Hey Elliott. I know you are really proud of yourself and all.... the guy towing the airplane was Garry Zinger. He has been at the Visalia airport since the day that Rodney shot the first rivet in that airplane. The reason that he towed the airplane up to the taxiway because it was under the direction of the airport manager. I believe there was a Notam. Perhaps in the future you will be spend less time worrying about your cameras. RIP Garry Zinger
Thanks for the comment I was sorry to hear about Garry’s passing. The purpose of the comment in the video was to talk about the wide range of factors with working at a new location and a new group of people (like construction and closed taxi ways). As stated in the video if there is someone at fault here it’s me for not stepping in to figure out what was going on and make sure we were all on the same page. My apologies if that segment landed wrong, that wasn’t my intent. RIP Mr Zinger.
Soaking it up -- it's all osmosis and reflection, especially the procedural discipline. The review of judgment calls, whys and wherefores, totality of situation as aggregated, is all instructive and the best ever. Takeaways: When it's a hydro check flight, chase needs to be there waiting for each event stage. Also, more attention to electrical underlying the process which seems to be at 95% instead of 110%. It feels guilty to gain so much from the setbacks of this fine owner/builder. Admire the tenacity and resilience. Wholehearted rooting for his success and triumph of the Bowerspony!
I really like this format! I always look for what I call "The Nerd Edition" videos on YT when it's about topics I'm interested in. When viewers subscribes to a channel about a test pilot and experimental aircraft they are interested in almost everything. E.g. what kind of helmet you're using, how you plan to bail out and risk assessment in general, and everything technical down to a tiny little bolt on the tail wheel. There are tons of channels with hours of pilots chatting about random stuff while flying, but that gets boring fast. I've looked a channel like this for a long time and I'm pretty sure your channel will grow big pretty fast if you keep making content like this. Personally I would like even longer videos with more details, and when you make timeline chapters so people can skip I can't see how that can go wrong. Keep up the good work!
Way cool. I’m very late to the party here but did notice that the left main was retracting before the door was fully open. Hope it didn’t have a sequence/interference issue later in some later vid!
Excellent video. I am not a pilot, but am the son of an AF command pilot. Ive loved planes all my life. You are an excellent communicator, the detail is easy to digest despite the tech heavy subject. Thats a very cool plane. You clearly love what youre doing. Thanks for this channel and your content.
GREAT CONTENT!!!!! Keep doing what you’re doing!!!! This is a GRAND-SLAM for Aviation enthusiasts!!!! Watching you guys trouble shoot issues and explain the fixes AWSOME!!!
Excellent format. Really enjoying all the details...and the lessons learned as a result of them. You're a real pro Elliot. Curious what the endgame is. How long is a testing phase scheduled to last? Or is it flexible contingent on results? At what point will you "sign it off" and call the testing complete? Seems like with a plane of this type a lot of these things (or other things) may continue to come up. I'm guessing planes like that are a maintenance challenge for the life of the plane?
Thank you for the note. We were initially brought on to fly the first ten hours. After ten we were invited to stick around. The airplane has certainly had some teething issues, but I honestly expected worse, those guys have been working super hard to make it come together. At the end of the day as cool as the Stewart is very few have been built. As a result they are all different and customized. Gear, Flaps, Controllable Prop, PSRU, Cooling System....its a lot of systems to figure out. And with that glide ratio the margins for error are slim. Thanks for the note!
Thanks so much for the reply...that makes sense. Hell I'd keep you around too ! Once they see your "system" I would think its obvious there is no better way to certify it safely.
@@utopiasnow But you are so good at them now ! Maybe the landing gear will work properly on the next two. LOL. Great content. PSUs too. Raptor had a PSU failure as well.
I appreciate why your test regimen must be so methodical. The feedback you give the builder is excellent to help them solve issues and to define out systems and handling. One things for sure, once you get through these issues, that (fingers crossed) will be as reliable as anything else!
I am astonished as to the logistics required!! Thanks!! I am fascinated by your power of mental recall in stressful situations! Great stuff! Glad you made it back to base safely!!❤️❤️
I said it before, I'll say it again; I just love this format! As a private pilot and airplane owner, there are always things to learn, to pickup from your videos. Even when my plane and engine is from a very different category. Very. Nice. Job! 🤙🏻😎
Really enjoying the longer format videos and appreciate the time it must take to edit and tidy up. Following the problem solving processes on the ground and in the air is very entertaining and thought provoking. Thanks & stay safe!
Once again a spectacular video full of information on the process you’re trying to accomplish and then when a fault may arise the response to that issue, coupled with the debrief. Solid work, keep them coming
Elliot - thank you so much for posting these detailed videos. As an experimental pilot/builder I always have concerns regarding my aircraft and how I will respond in an emergency. I feel like I learn something from your in-depth analysis of both in-flight and post-flight issues. Clearly your professional attitude is both impressive and provides a real-world learning experience. Thanks again!
Thanks for saying that. The effort for these longer videos is correspondingly bigger, but feedback like this makes it worth it. What airplane are you working on now?
Great Video Elliot. Hope this plane gets the bugs ironed out with time. Great format Really useful to see the brief and debrief and your critique of where to improve.
Another great video about the tests on this aircraft. The detail is terrific, the style is engaging, and I always learn something very new. Keep up the great work and dedicated effort. Airplanes really are cool...
Thank you for taking the time to make these videos so informative and enjoyable to watch. Being able to watch the development of an aircraft from the perspective a test pilot is fantastic and pretty rare. The biggest takeaway I get is how you're able to 'normalize' abnormal or unexpected situations and deal with them methodically and effectively. It has improved my own troubleshooting in the cockpit, so thank you. I like the music a lot - you can't please everyone so just do what makes you happy and lets you express yourself, it's your channel after all. The AWOS mixed in with that beat; that was really rad. Cheers from Australia
Fantastic format, as I noted on your last vid. You are taking us along on the test program, which I find fascinating as a pilot. Love all the nerdy details... and great footage editing etc. Keep on keepin on. Also, props to the chase plane for wearing masks... It sucks I know, but it works. Too many people not following those recommendations, will take forever to get back to normal.
Elliot, I like any and all efforts you make to post these videos and the longer format is good. Bottom line is that you are showcasing an original and unique perspective of the aviation experience and that is all that matters. We're lucky you want to do this and share with us.
Jerky motion Is a symptom of air in the hydraulics to my untrained eye. Not sure where the leak mentioned is but if oil can get out air can get in. Very interesting thanks for sharing
Thanks Elliot for the in depth review of your test flights. Your flight planning and sticking to a game plan during a flight and observing all the data that is available to you at that given time is stellar. Keep up the great work!! Love your channel.
Great stuff guys , your procedures are really thorough and you dont miss much . Great for risk reduction. Love your flight test work best out there. Be safe.
Elliot, I happen across your videos some time ago and I really find myself enjoy them. Thank you, I know it is time consuming putting them all together. I simply enjoys listening to a professional that is quite obviously skilled at his craft. It is a rare find indeed to find someone that is comfortable in there own skin to have the humility you do. You own your mistakes and expect others to do the same. That’s how I know your good at what you do! I’m just a fairly low time VFR PPL that loves flying so you won’t get any arm chair quarterbacking from me. My grandfather was a pilot and later a test pilot just after WWII. He and his friend Chuck Yeager learned to fly out in Taft CA on Gardner Field. That’s where he and my grandmother are buried now. Anyhow, they were both mechanics together before learning to fly. Growing up around some of those guys was pretty awesome. Anyhow, stay safe and Blue Sky’s my friend.
Thanks for the note. Sounds like yours was a house filled with great people telling great stories. Keep me honest if you see anything, I think I can take the feedback. airplanes are cool
The only thing I would suggest is to have chase do a departure pick up like you have done in the past with this aircraft. My flight testing is in the rotary wing world so we have the luxury of having chase aboard from the time we leave the chocks, however, when we utilize a fix wing as chase we always do a departure pickup even if the mission is a low risk. As you well know any risk is a risk that can compound when things are not going as planned/expected. When you have an anomaly chase is there to give you immediate feed back of the situation to help cool the helmet fire. We have found that it is strong risk mitigation . Just my two cents worth. Love the new format. I can’t wait for more.
Thanks for the comment. We recently got bit by low chase on this program, so we switched back to high chase. The real answer is a chase plane that can keep up. Maybe someday.
Yeah, its been a tough few months. The nature of the issues require a lot of man hours to diagnose and address. Meanwhile a complex airplane with lots of new stuff on it, distributed knowledge on all the systems, ideas on how they play together. We all appreciate Rod's gorgeous airplane and are trying to help him get his dream to the next step. The saving grace of the program is its a good group. Which makes everything easier. Thanks,
don't disregard the low voltage flash. when you first hit the gear up switch the hydraulic motor is under a very light load, but as the gear gets higher the load on the hydraulic motor increases drastically. the flash you saw on the low voltage indicator tells me the battery / wiring to the hydraulic motor cannot supply enough power to finish the cycle. this drops the pressure and then the motor has a harder time to get it back as well. this also messes with the pressure regulator. so you get a "pumping/ surge " cycle going. ..... motor/wiring cannot get enough juice to run without dragging down the voltage, making the motor now to under powered to continue. if you set the pressures up you'll get past it sometimes as the motor is under strain for less time (faster cycle). test: connect the low voltage indicator directly to the motor actually physically AT the motor to see actually what it's getting to work with and get a digital scope to monitor this and save the voltage profile all thru the whole cycle. now you can actually see the motor strain as it works. be aware that testing on the ground, does not simulate flight. especially in electrical. to just cycle the gear alone is not valid as the battery is at it's best...... Test with full avionics/radios/lights on and engine running. each system lowers the battery voltage a little. is the aircraft alternator regulator able to compensate and support the aircraft even at idle? or are you slowly eating away at the battery voltage with a long taxi or long ramp time, then asking it to get the gear up while it's weakened........ a weak or under rated battery could be the cause ,...... but i would be looking at the wiring to the motor, and a probable increase in the wire size (lower gage) to not have as much wiring voltage loss to the hydraulic motor. now redo the scope test . every piece of wire, connection, switch, will affect the performance of the motor. wires are like rubber bands. each one stretches(looses a little power) depending on load (amps used). more load=more stretch=less voltage to work with smaller wires lose more, heavier wires lose less..... length also matters..... take some measurements and see what the motor has to work with. love watching you work.... i've been following this since the beginning, even talked with Jim and Peggy years ago about buying the company he had about 43 kits sold then....before the trouble he had with his overseas production tooling getting tied up in foreign country. please pass this on... to them thx Jim
If you read the history of the 'Mustang' you might come across the information that Several Mustangs were lost due to inner wheel door failures. It seems someone decided to eliminate the door locks on the inner wheel doors which allowed them to partially open during flight at cruise speeds. The result was that the planes suffered catastrophic failure of the wing and crashed. This only came to light when the mechanics and engineers jacked up one of the planes to test the systems and couldn't find the problem. The tale says, They went to lunch leaving the plane up on jacks with the gear retracted and when they returned to their surprise one of the doors had leaked off pressure and fallen open as the plane wasn't equipped with uplocks on the inner wheel doors.
I really enjoy watching her fly and the senior gentlemen is a wealth of knowledge. Thanks for doing a great job of walking us through the process and educating along the way. 👍🏻✊🏻✊🏻
Thank you James. It's a long story, but the summary is it's hard to look stoic and too cool for school when you are fist-pumping. And I haven't been to an airport recently that needed more stoic/super cool people in airplanes. Woot woot! airplanes are cool!!!!!
Elliot Seguin I was wondering the same thing. Thought that it was a symbol of grinding (putting in the work) and reminded me of old steam locomotive 🚂 wheels as they are starting to roll! Whatever the backstory, while the stoic look has a place and time that is cool, I agree that so does the celebration dance! Keep making aviation cool for everyone and not just the “select few”.
Well done! The blending of the video editing and story keeps getting better. In your early videos, you were always good at telling the story and the video shot was good. I think that you are using more cameras which helps tremendously. Just like when you are testing a plane, the more purposeful data you have, the better you can understand what needs adjusting/fixing, what is working right and what isn’t. I know that more cameras 📸 means more editing and that is the bane of most “TH-camrs” but it makes a huge difference in sharing the story at a level that keep both the highly experienced and educated and those (like me) who are more layman than expert engaged. This video is a better version of showing while telling. Thanks for putting in the time and work to do it. Oh, an like everyone else, love the music selection!
Thanks for that. I wasn't sure that the two added cameras would add technical value (beyond a storytelling purpose), but they absolutely did. Stoked you can see it.
Very impressed by this: First of the detail of the video (thank you!) and 2nd by the procedures you apply before, during and after the flight. I run a web hosting company and we do similar things on big and important changes or maintenance: pre-execution briefings (going through everything and making sure everybody is informed - and yea we also have cases like the tractor person, in our situation it's more like a customer freaking out :). What we're not doing yet: a post-briefing where we go through everything that happened step by step with everybody confirming their approval or possibility to add. Will totally do this in the future! Thank you!
As a fellow IT professional I can attest to the value of both post-flight debriefs and "post mortem" debriefs after a major update or outage. Its important that they don't turn into a "blame-game" and get personal; but rather focus on things that can be done better next time through concrete action (i.e. different comms verbiage, adding checklist items, cross-checks, etc). One way to help with that at company meetings is to alternate talking about 1 thing that went poorly, and then 1 thing that went well. Having those little moments where people can pat each other (or themselves) on the back avoids falling into a big negative spiral.
@@noelwade and I think that's exactly what I'm so impressed by Elliot and other test pilots: the capability to look at faults, even if they are human faults, and just accept them with no blame, and not only this but also search an improvement on themselves that could have prevented the situation. I think that's a huge skill that we should flex more and more, not just while flying or work.
The style and content really work for me. Love the snappy changes as they help deal with all the information we're getting, so there's no info overload at any one time. Aced it again! Keep up the excellent work Elliot 👌👍
I fly fully-certified and well-maintained jets for a living -- nothing close to experimental -- and I really enjoy hearing your thought processes and analysis for handling abnormal scenarios. Another great video, with this one going all out on the editing / music. Keep up the great work, Elliot.
Loving the classic g shock watch, missing the tunes. In all seriousness, great content, great information. I do like the mix of technical knowledge and artful composition. You have developed a unique style over the years with these video, I wouldn’t stray too far from what has been working. Thanks again, looking forward to the next one!
Awesome debriefing! I work with a bunch of hospital executives and have discussed debriefing benefits with them. I'm thinking I'm going to show them this video to show them how it's done.
This is not the only Mini P-51 with landing gear problems You were involved with If the Hydraulics pump loads and knocks the Engine out You would think they would put the Hydraulics on an independent power source
Yeah tough day. In all fairness the hyd pump had its own properly sized breaker. It was this odd but per the plans main breaker that was the issue. Anyway, thanks for the comment. Good to have you here!!
@@utopiasnow I think that it's a very complicated plane he has had to redesign the control system he should have known mounting control cable pulleys directly on the skin would be a problem the PSRU is a unproven design the engine is unproven I think it's about 1000lbs overweight and he has had to cobbled together too many stop gap fixes. I'm just saying be careful with that one. With that being said I really hope to see it in the air soon 😊
1 2 3 4 This type of video is...Outstanding...This plane sure got a lot of "bugs"....May be to many hands....Just saying....Thanks my friend....Fly safe...!
Love it. Thanks for taking all the time to put these videos together - I know that editing multi-camera footage and snipping out all the important bits takes *many* hours of work! Its great to be able to understand your methodology and see the thought processes play out. My upcoming Sonex first flight will be _far_ less sophisticated than any of the ships you're testing, but its still great to be able to see your experiences and glean little nuggets here and there. Reading about flight testing is all well & good, but seeing attitudes and decisions play out is also hugely beneficial. Thanks again!
Air speed could play a part in the gear binding up, but it's most likely a pressure issue like air in the system which would also cause the pressures to read low and spike around. I would cycle the gear on the stands with about 100lbs of force pushing aft on the wheel to see if you can reproduce the issue after bleeding the system.

My flight testing is in the rotary wing world so we have the luxury of having chase aboard from the time we leave the chocks, however, when we utilize a fix wing as chase we always do a departure pickup even if the mission is a low risk. As you well know any risk is a risk that can compound when things are not going as planned/expected. When you have an anomaly chase is there to give you immediate feed back of the situation to help cool the helmet fire. We have found that it is strong risk mitigation .
Just my two cents worth. Love the new format. I can’t wait for more.
Thanks for the comment. We recently got bit by low chase on this program, so we switched back to high chase. The real answer is a chase plane that can keep up. Maybe someday.
Great Video....there seemed to be a lot of frustration in the debrief room for sure.
Yeah, its been a tough few months. The nature of the issues require a lot of man hours to diagnose and address. Meanwhile a complex airplane with lots of new stuff on it, distributed knowledge on all the systems, ideas on how they play together. We all appreciate Rod's gorgeous airplane and are trying to help him get his dream to the next step. The saving grace of the program is its a good group. Which makes everything easier. Thanks,
don't disregard the low voltage flash. when you first hit the gear up switch the hydraulic motor is under a very light load, but as the gear gets higher the load on the hydraulic motor increases drastically. the flash you saw on the low voltage indicator tells me the battery / wiring to the hydraulic motor cannot supply enough power to finish the cycle. this drops the pressure and then the motor has a harder time to get it back as well. this also messes with the pressure regulator. so you get a "pumping/ surge " cycle going. ..... motor/wiring cannot get enough juice to run without dragging down the voltage, making the motor now to under powered to continue. if you set the pressures up you'll get past it sometimes as the motor is under strain for less time (faster cycle).
test: connect the low voltage indicator directly to the motor actually physically AT the motor to see actually what it's getting to work with and get a digital scope to monitor this and save the voltage profile all thru the whole cycle. now you can actually see the motor strain as it works.
be aware that testing on the ground, does not simulate flight. especially in electrical.
to just cycle the gear alone is not valid as the battery is at it's best......
Test with full avionics/radios/lights on and engine running. each system lowers the battery voltage a little.
is the aircraft alternator regulator able to compensate and support the aircraft even at idle?
or are you slowly eating away at the battery voltage with a long taxi or long ramp time, then asking it to get the gear up while it's weakened........
a weak or under rated battery could be the cause ,...... but i would be looking at the wiring to the motor, and a probable increase in the wire size (lower gage) to not have as much wiring voltage loss to the hydraulic motor. now redo the scope test .
every piece of wire, connection, switch, will affect the performance of the motor.
wires are like rubber bands. each one stretches(looses a little power) depending on load (amps used). more load=more stretch=less voltage to work with
smaller wires lose more, heavier wires lose less..... length also matters.....
take some measurements and see what the motor has to work with.
love watching you work.... i've been following this since the beginning, even talked with Jim and Peggy years ago about buying the company he had about 43 kits sold then....before the trouble he had with his overseas production tooling getting tied up in foreign country.
please pass this on... to them thx Jim
Thanks for the detailed comment.
Great comment 👍🏻
Wouldn't that be an amperage issue, not a voltage issue though?
l agree...
@@noelwade if the amperage is maxed and the breaker doesn't pop, the voltage will drop.
Great as usual! Thanks guys
Thank you Randy!!
Great length of video, could go longer, no issue.
Thank you!!
Good stuff! Keep it safe.
Thanks, will do!
If you read the history of the 'Mustang' you might come across the information that Several Mustangs were lost due to inner wheel door failures. It seems someone decided to eliminate the door locks on the inner wheel doors which allowed them to partially open during flight at cruise speeds. The result was that the planes suffered catastrophic failure of the wing and crashed. This only came to light when the mechanics and engineers jacked up one of the planes to test the systems and couldn't find the problem. The tale says, They went to lunch leaving the plane up on jacks with the gear retracted and when they returned to their surprise one of the doors had leaked off pressure and fallen open as the plane wasn't equipped with uplocks on the inner wheel doors.
Fantastic video as always. Love all the information Elliot. Thank you!
Thank you Mark!
2:40 pretty cool how the entire aircraft scoots back under the canopy. 🥴
Very enjoyable and I really like the format. The “mind set” the group displays is very impressive,,, I am learning a lot. Thank you for the posts.
Thank you for the comment
I really enjoy watching her fly and the senior gentlemen is a wealth of knowledge. Thanks for doing a great job of walking us through the process and educating along the way. 👍🏻✊🏻✊🏻
Thanks for the comment. I appreciate the feedback.
Thanks for sharing this. I always learn a lot from the detailed briefings, thanks for your great work and invaluable expertise.
Thank you Mike!
You're really hitting your stride on the editing and formatting/directing. Awesome video.
Thank you Adam
Your content is very unique, amazing video as always.
Thank you very much! Glad you think so.
Crap, I have too many questions...need to do some reading.
Thanks
Love the videos !
Thanks PR
Please give more info on the raptor program in Georgia as i live in Athens Georgia and would love to meet you guys and see the plane
Really enjoying these long form videos. Well done. Is there a back-story on the fist pump ?
Thank you James. It's a long story, but the summary is it's hard to look stoic and too cool for school when you are fist-pumping. And I haven't been to an airport recently that needed more stoic/super cool people in airplanes. Woot woot!
airplanes are cool!!!!!
Elliot Seguin I was wondering the same thing. Thought that it was a symbol of grinding (putting in the work) and reminded me of old steam locomotive 🚂 wheels as they are starting to roll! Whatever the backstory, while the stoic look has a place and time that is cool, I agree that so does the celebration dance! Keep making aviation cool for everyone and not just the “select few”.
No one does a better double fist pump than the Legendary #giddyfelix 😎
Well done! The blending of the video editing and story keeps getting better. In your early videos, you were always good at telling the story and the video shot was good. I think that you are using more cameras which helps tremendously. Just like when you are testing a plane, the more purposeful data you have, the better you can understand what needs adjusting/fixing, what is working right and what isn’t. I know that more cameras 📸 means more editing and that is the bane of most “TH-camrs” but it makes a huge difference in sharing the story at a level that keep both the highly experienced and educated and those (like me) who are more layman than expert engaged. This video is a better version of showing while telling. Thanks for putting in the time and work to do it. Oh, an like everyone else, love the music selection!
Thanks for that. I wasn't sure that the two added cameras would add technical value (beyond a storytelling purpose), but they absolutely did. Stoked you can see it.
Very impressed by this: First of the detail of the video (thank you!) and 2nd by the procedures you apply before, during and after the flight. I run a web hosting company and we do similar things on big and important changes or maintenance: pre-execution briefings (going through everything and making sure everybody is informed - and yea we also have cases like the tractor person, in our situation it's more like a customer freaking out :).
What we're not doing yet: a post-briefing where we go through everything that happened step by step with everybody confirming their approval or possibility to add. Will totally do this in the future!
Thank you!
Thanks Michael, I am glad any of this is useful.
As a fellow IT professional I can attest to the value of both post-flight debriefs and "post mortem" debriefs after a major update or outage. Its important that they don't turn into a "blame-game" and get personal; but rather focus on things that can be done better next time through concrete action (i.e. different comms verbiage, adding checklist items, cross-checks, etc). One way to help with that at company meetings is to alternate talking about 1 thing that went poorly, and then 1 thing that went well. Having those little moments where people can pat each other (or themselves) on the back avoids falling into a big negative spiral.
@@noelwade and I think that's exactly what I'm so impressed by Elliot and other test pilots: the capability to look at faults, even if they are human faults, and just accept them with no blame, and not only this but also search an improvement on themselves that could have prevented the situation. I think that's a huge skill that we should flex more and more, not just while flying or work.
LOL the freaking tractor guy just showing up and taking the airplane.
The style and content really work for me. Love the snappy changes as they help deal with all the information we're getting, so there's no info overload at any one time. Aced it again!
Keep up the excellent work Elliot 👌👍
Great to hear! Thank you Kevin.
I fly fully-certified and well-maintained jets for a living -- nothing close to experimental -- and I really enjoy hearing your thought processes and analysis for handling abnormal scenarios. Another great video, with this one going all out on the editing / music. Keep up the great work, Elliot.
Thanks man, I appreciate the perspective. Very different worlds, I am always very impressed by the certified jet world.
Loving the classic g shock watch, missing the tunes. In all seriousness, great content, great information. I do like the mix of technical knowledge and artful composition. You have developed a unique style over the years with these video, I wouldn’t stray too far from what has been working. Thanks again, looking forward to the next one!
Thank you Greg. I am glad you dig my old Casio.
Great video. I could watch an hour long video of yours.
Thank you Mac, I appreciate the support.
Awesome debriefing! I work with a bunch of hospital executives and have discussed debriefing benefits with them. I'm thinking I'm going to show them this video to show them how it's done.
I hope it helps. Thank you.
Really like the format and style of the video. Learning a lot from your test methodology. Thank you!
Thanks Paul!
Great stuff Elliot! We're super stoked for you and the Dudeman to come fly the Raptor prototype! Get that baby airborne!
Thanks Mike, video coming soon!
I love your videos, I’m definitely getting benefit from it 😀
Great to hear. Thanks for coming along.
This is not the only Mini P-51 with landing gear problems You were involved with
If the Hydraulics pump loads and knocks the Engine out You would think they would put the Hydraulics on an independent power source
Yeah tough day. In all fairness the hyd pump had its own properly sized breaker. It was this odd but per the plans main breaker that was the issue. Anyway, thanks for the comment. Good to have you here!!
Nice work guys! 👍
Glad you enjoyed it!
I shouldn't be leaking at all, is most likely a crimped gasket, a seal would leak heavy, ,,, gaskets are tricky sometimes on any motor !
Beware of the Raptor that thing is a mess
Thanks for the comment. Any specific concerns?
@@utopiasnow I think that it's a very complicated plane he has had to redesign the control system he should have known mounting control cable pulleys directly on the skin would be a problem the PSRU is a unproven design the engine is unproven I think it's about 1000lbs overweight and he has had to cobbled together too many stop gap fixes. I'm just saying be careful with that one. With that being said I really hope to see it in the air soon 😊
Wow you are professional I love it I love hearing you talk about what happened. That was a nice airplane
Great stuff, keep up the great work! Amazing videos.
Glad you like them!
Do other test flights like this always have this many don’t want to say problems but problems?
1 2 3 4 This type of video is...Outstanding...This plane sure got a lot of "bugs"....May be to many hands....Just saying....Thanks my friend....Fly safe...!
Thank you Steve!! I appreciate the note and the thoughts.
Love it. Thanks for taking all the time to put these videos together - I know that editing multi-camera footage and snipping out all the important bits takes *many* hours of work! Its great to be able to understand your methodology and see the thought processes play out. My upcoming Sonex first flight will be _far_ less sophisticated than any of the ships you're testing, but its still great to be able to see your experiences and glean little nuggets here and there. Reading about flight testing is all well & good, but seeing attitudes and decisions play out is also hugely beneficial. Thanks again!
Thank you Noel, I am glad you enjoy it and find it useful. Best of luck with your sonex, fun times ahead for you!! I am jealous.
airplanes are cool
Thanks for the early morning Aviation treat Elliot
Good show buddy!
Any time! Thanks for the note!
Air speed could play a part in the gear binding up, but it's most likely a pressure issue like air in the system which would also cause the pressures to read low and spike around. I would cycle the gear on the stands with about 100lbs of force pushing aft on the wheel to see if you can reproduce the issue after bleeding the system.
Thanks for the advice. I appreciate it.
Also can't wait to see you get the raptor off in these coming weeks elliot.
Great video, very informative, very well filmed and edited. Learnt lots!
Really enjoy your videos but sometimes the music gets a little annoying. I'd rather hear the sound of those wonderful old planes.
