Did you remember prop size?
Great work Charles!!! Glad to see this girl fly, can’t wait to get mine in the air soon👊🏼👊🏼
Outstanding aircraft Charles. What a buety. Nice flying!
I like it! I was thinking I'd drop the speed brake with full flaps. Have you tested the brake yet? Thanks for posting your flight videos
nice field!
I loved the flying, completely engaged. I have this plane, I it fly it every outing.
For those who care.... The crash occurred on 3 May and the plane was repaired and flying again on 7 May. www.rcgroups.com/forums/showthread.php?3473121-3D-Lab-Print-B25/page9 Watching the end of the flight in slow motion it's clear that I got too slow on final approach. At 6:15 you see the plane roll out of the turn onto runway heading, but in a slightly nose high attitude. At 6:18 the stall occurs and the nose starts to drop. At 6:19 I pulled full up elevator and added power, but it was too late. The plane impacts in a nearly level attitude but with a high rate of descent. After that all I could do was watch the inevitable.
You took of the other way. Were you landing downwind?
There was almost no wind that day.
Stall? More like you let it drop like a rock onto the ground.
Nice video. Enjoyed the sight of the two flying formation.
Nice formation flying, 👍🏻🙂
The pilot was correct he did stall it in. Low and slow coupled with a high wing loading and the result is obvious.
What a shame. Hopefully it can be repaired.
"Stalled it in"? Not sure.
High wing loading.
Sorry for your crash. Trying to be constructive so as to learn, in the video i heard you say you " i stalled it in". Just to be clear after watching and playing back crash a couple of times in slow motion would it be correct to say , you actually missed judged decent rate and never flared, it looked like plane was flying, you just flew it into ground thats why it bounced. Then after bounced plane ended up in extreme angle of attack and then quit flying and tumbled. Only save at bounce would be to full power and go around and hopefully regain flight control ?
@keepyourspeedup - Yep, he never flared and pancaked it. And that resulting bounce was so nose high I doubt he good have saved it by firewalling it and trying to do a go around. Anyway, it should be repairable since he can just 3D print whatever new parts he needs. :)
Yep, totally agree with this assesment. The pilot misjudged the rate of decent and distance to the ground.
@@Jimbo-in-Thailand Actually, repairing 3d printed planes is a pain. After a crash like this most likely 80% needs to be re-printed. Almost a complete do over. Foam planes are much nicer in this regard.
@@adamtrzaskowski3901 It depends on the damage. His fuselage clearly broke in half and another piece flew off, maybe a wing tip. Since 3D printers (at least mine is) are so freakin' slow I would definitely try to salvage this model. Of course, that's assuming there's not a lot of other damage, cracks, etc., we can't see.
Flaring a model plane is an exeptional event, and doesn´t occur with all types of airplane. The trick of a good landing is actually easy to explain (probably not easy to achieve): come down in a quick descent, and keep it parallel to the ground, the closest possible; let the speed drop, until it touches the ground.
Ha ha POJ
Nice flight. This video is one of the reasons I bought the jet. I have really enjoyed flying it.
Cool flight I’m curious why does it count down?
Great engine, great sound!!! Where did you find that spinner? Do you have any reference? Thank you
Great flying! Could you kindly advice the parameters of your bungee? And how you made the hook on the model?
You won't need the gyro Charles, mine flies like it's on rails. I have 40 planes and do not fly with gyros, only thumbs, bad eyes and brain! Hahahahaaa Good flying though! I also invert her 2 feet off our 500 foot runway! WooHoo
You are quite the pilot!
@@charlesradford3811 I just love to fly Charles, when I get a chance!
Hello. Did you use the DLE motor suports? If I need get more 2cm is is a lot
I used 3" DA standoffs plus a 5/8 plywood spacer with a DLE 55 RA. Stock DLE are too short.
@@petercyr3508 l get 2 standoffs and cut the longer option
Nice flight Charles!
Beautiful plane and flight! Nice area. 👍🏻
Awesome plane and great flight
that is really cool!!
Did you adjust the timing at all? What size lipo are you using? Cheers.
No, I didn't change the timing. I'm using 5000 packs.
@@charlesradford3811 would you say it gives out close to it's claimed 4-4.2kg of thrust? I ordered one to go into my viper and the viper motor to go into my f22
@@M4rkmcc21 Yes, I think it does
Very nice. The flight and the plane itself .
Excellent Charles, those twin batteries are definitely the way to go. Mines on the bench waiting for the same. I know you mentioned it before, but did you go with tailerons? I know you're using full span flaps, but do you also have flaperons, which is all I've been using. With the extra channel now available from removing the speed brake, thinking about tailerons, but would it make any sense to have both, with flaperons?
Hugh, this plane does not have flaperons. The surfaces on the wing are used as flaps only. As I recall, I had to change the rotation of one of the wing servos so that both servos could be connected to one channel and move the flaps correctly. The tail surfaces are used as tailerons and provide more than enough control. I used a Hobby Eagle A3-L gyro to handle the tail surface mixing. When I first flew the jet I had the wings surfaces as ailerons and the tail surfaces as tailerons....the roll rate was way too fast. I converted the ailerons to flaps and that gives me better takeoffs and landings.
@@charlesradford3811 thanks for the info Charles. I may just follow your lead. I'm using the 8 channel Spektrum AS3X and may be able to program it through its wing/tail type options without changing the wing servo and at least I now know to un y the elevators and put each of them on their own channel as long as I'm taking it apart. Hope to start surgery soon and may need to PM you for more of my stupid questions. Thanks so much.
Nice. Did you try it without the gyro at all?
Yes, I flew the first 5 flights without.
gyro? or no gyro?
Yes.
Excellent Charles, much better than the last one you flew and that 2nd landing was butter. 🤙 Just upgraded mine with the FMS 12 blade fans, not that it needed it, but these give 25% more thrust and should help me get off grass even better. Hope to try them Monday, but our weather has been very windy for 6 weeks now. BTW, the TV nozzles are outstanding, you may want to install them as well.
Thanks. I'll be looking for your results with the new fans.
Known trait with this bird... inability to recover from this high an aoa due to upthrust. The only only thing to do is poweroff until the nose drops but you need ~200ft alt to recover. He only had 20ft.
Did you feel it increased the performance enough that you would do it again? Im looking to dp the same for my viper cause i want better verticle and top speed, but the extra weight and cost may not be worth it of its only a little improvement.
Honestly, no. The difference isn't that much.
@@charlesradford3811 thanks for getting back to me. Thats some good flying skills you have.
Did you have to rewire the plane for this or just undo a Y connection?
Did you found a solution to this issue
Beautiful flight and a perfect landing
She sure flies nice, smooth landing as well. Great looking weather to boot! Looks like a zero "pucker factor" EDF. 👍
You have flaps?
Yes. Tailerons to control the plane...flaps on wings for speed control.
Wow nice flying, I love it and subscribed to your channel 😀😀😀 Great what you did to the setup, those twin lipos and FMS units are a big winner, it makes me want to add this plane to my hangar 👍🏻 Greetings from Belgium!
Thank you.
You really got this thing "rockin" with the FMS fans and dual batteries. Outstanding! Oh yah, BTW, text book landing.
Would be nice to enter more info about gyro, which brand! and how it setup is done?
Hobby Eagle A3L gyro from Motion RC
Nice flight. What battery set up were you using?
Two HRB 6s, 4000mah
Nice flight Charles. It's too bad HH sold these with such an underpowered setup, it is nice looking and a great airframe if set up correctly. Your mods with 2 batteries and ESC's was a great idea. I'm actually OK now with just the new FMS fans and a lighter 5300 SMC, at 700gr, it gives me about 3:20 in flight time and flies so much better with a CG of 150 or more. If I wasn't working on a repaint of the Mig, I'd probably follow your leed on the twin batt for the SU-30, well done!
Good job on your flight ✈️👍
Great video and landing!
You hit a bump and the plane when airborne, you did have two choices,one relax the elevator and let the airplane keep in stray line, the other option was to keep the full power and put the nose down, you decision of cut power, was the worse, but we all make mistakes, sorry for you lost.
There was simply no other choice, but to crash. With high AOA, you cannot push the nose down if you add throttle, it pushes the plane up. And the ttw ratio is less than 1, so the outcome must be a crash.
Did you only have two positions for flaps? I heard “Flaps down” and then “Flaps up”. I use a 3 position switch that gives me about 15 degrees for takeoff and 30 to 40 degrees for full flaps. I also use a stick position switch that raises the flaps from full to takeoff when my throttle is above 60%..
I’m thinking of getting this plane and using a dle 55ra. Would you recommend this plane after having it some time? Is it a true 86” wing. Years ago I had a seagull model that was not as advertised. Thanks
Yeah you can definitely get her slower for sure. It is definitely a sweet flyer! Mine has over 170 flights and over 3 years old.
