- Hi viewers please like and subscribe to my channel. Click on notification bell for more videos. This is Free Wing Motion RC Avanti V2 80mm EDF Jet and unfortunately bit the dust. What transpired up there, it's beyond comprehension. While trying to bring her back to landing, I lost control of it and sticks/gimbals input were not affecting it and it started rolling gradually and plummeting and ended up crashing into the ground real hard and disintegrated into pieces, beyond repair. Please comment and explain what you observed and what could have been the cause of its premature demise. This is my second plane following the crash of FMS Viper 70mm 15th Anniversy Edition.
Plane: MotionRC Avanti V2 80mm EDF Jet
Rx: Frsky Archer SR 10+
Tx: Frsky X20s
Battery: HRB 6S 6000mah Lipo
Cam: DJI Osmo 5 Pro
Crashed on Maiden on Saturday 11/23/2024
Wind: 12+mph with 15+mph gusts
I have flown jets and EDFs for many years and I think I have an advise for you. I have also totalled a jet worth many times what your Avanti was worth and I now how it feels. So here is my thoughts. You crashed because you flew to far away from your self. Its nothing strange with that, that is exactly what happens when you cant see the model properly. Next thing is that you flow to far away for to reasons. Number one is that you flow very fast. That model can fly easily on one third of that speed. Number two is that I think that you were unprepared for how fast the model got away. When you fly jets and other fast ships you have to make up your mind in beforehand about where you will go next and after that an so on. Third advise., don’t use the flaps. They have very little practical use on the Freewing Avanti. Start and land without them until you know your way around and then when you feel more at ease you can start to explore them.
So my advise to you Is. Bye a new one. Shit happens. Next time only use full power for take of, then throttle back, a lot. Decide were to go after take of and were to go after that. Use the throttle, its not an on/off switch! And above all, keep close!
Good luck!

Huge thanks for your awesome advices. I always appreciate advice(s) from anyone more experienced than me as you are more experienced. I've seen in one of the videos that's true that it can fly and land well without the flaps. However, since it's a fast jet and in multiple videos pilots have extremly slow low pass with the full flaps deployed/extended, that's of course the case of low/slow passes. Yes, I did fly it fast but I made sure that my throttle was not 100% it was 50% and did transition to 100% on one of the low passes. Also, I will try to reduce my flying envelope. I will upload a few more videos not me flying but one of the very experienced pilot of my club, who recommends only 10% expo and even he flew 80mm Mig-29 twin little far. Anyway, thanks again for your kind wishes and advices. Appreciate your comments, and I am going to follow on these advices I am getting from great pilots all over here with their nice comments.
@@jannicawunge4940 speed has NOTHING to do with this lol
@jannicawunge4940 I'm sorry this is bad advice do you even fly??
@@jannicawunge4940 flaps work very well on the Avanti I've had 2
That wall of text was difficult to wade through. The word is 'advice', BTW.
Maybe English is a second language?
It was a great model. I love mine, fast and on rails. It is true that you may have flown too far away and full throttle all the time but hey we all have done it. This Avanti is one of the best edf planes ever designed and made. Get a few more.....
Thanks for the comments. I have not flowin it throughout full throttle, I kept transitioning between full and half, however, I think I should have kept flying the Habu. I will get another Avanti V2 and would wait until I am fully confident with my Habu as I fly it without any issues. It does not have flaps, however Habu is a great trainer. Did I fly very far, well the DJI Osmo 5 Pro is an action camera and does not zoom therefore she appeared to be flying far then it looked.
Sorry for the loss loosing orientation can really mess you up that's how you learn mistakes happen!! keep flying
@lucaspoole8866 Thank you and I appreciate your kind words. Yes, I'd not stop flying.
loosing the orientation twice is no fault of the model. Keep it closer or get bigger and maybe slower models. :-)
Once you get it trimmed out enough that it flies straight, start shooting approaches and land if it feels right. Don’t play jet jockey until the battery is done.
@TheRCAviator I did say the battery ran/drained out. However, upon checking, it was 30%, which had enough juice to bring her down on the ground safely. To be honest, I didn't have to trim her at all as she flew so good.
First, I have to offer my standard RC crash sympathy reply....
That'll buff right out. 😅
Secondly, RCAviators comment rings true. It's a practice I learned from piloting and transitioning between multiple General Aviation aircraft types. I carry that technique to the RC world, as well.
Take it up on a full charge, get it trimmed perfectly, practice several slow, flap down passes at a safe high elevation for a recovery cushion, let it stall a few times to understand the speed limitations, then start doing touch and goes for the remaining battery life. Always keep it in as close as the aircraft will allow in the turns.
So far, this has prevented me from bending and trash-binning a whole bunch of spendy planes on their maidens. I guess my local clique of RC aquaintences tend to appreciate my discipline as I can't count the number of controllers that have been handed to me by others that are apprehensive about their first launch of their foamer or composite investment!
God willing my success streak continues because I'd feel awful bad binning someone else's airplane!
Shiny side up!
I would recommend flying on battery telemetry voltage callouts.flying wide open throttle gives no time for the lipo to regenerate and will hit low voltage cutoff.also recommend programming the esc and turn off low voltage cutoff.
Thank you. I'll definitely work on it and set them up.
I recently totaled my V1 Avanti, so I completely understand. Get another one, they are great planes!
@@jkepps That's the plan and looking for Avanti V2 ARF Plus.
Best to fly as far away as possible when testing a new airplane
But mostly experienced pilots are advising otherwise.
I always cut expected flight time by 50% with a new aircraft. I increase the flight times based on remaining power. Not all at once and definitely allowing for how much throttle is being used. I use telemetry that monitors pack total voltage not the voltage going to the ESC. I set my alarms based on that value. I record the battery and throttle use per flight. I usually just download and save. It’s useful to figure out how set values and troubleshooting. I have never had an issue with the ESC being powered by the flight battery. I have had issues with ESC reset for other reasons but not available power.
I personally don’t fly a long ways away from myself with a new project. If it doesn’t trim out within a couple of passes I land it and figure out why. I also don’t do any turns that exceed 90 degrees in my landing pattern. I learned after awhile.🙂
Correction: I monitor the total pack voltage not the voltage going to the RX/ESC. It pulls directly from the balance plug on the battery.
@voivode2591 Thanks for the amazing advice, and given your experience, it's really something to learn from.
I love my Avanti. At our flying field in Holland we always fly north of us so we don’t ever see the sun in flight. And still they’re quite fast and hard to see
Thanks for the response. I appreciate it. You're right the advices I am getting is to fly it at a slow speed, however, I am not a full throttle guy, but I will make sure to fly it slow and keep it under control in future to bring her back safely to the ground.
Wow, you fly so far away!
I'll upload the videos of one of our club members with 30 years of flying experience. As I shot these videos with DJI Osmo 5 Pro, Action cam which is not capable of zoom in therefore it looks it flies far. I'm going to reduce my flight envelope from this point on. Thanks for the comment and liking it.
Very sorry for you. I feel the lose that is why I 3D print my planes these days. Print build fly crach repeat.
@@GuusK thank you for your kind words. Appreciate it.
You were at times flying way to far away . Probably just lost orientation
@Mikeylikesit1968 I did fly a little deeper, and that's how I fly my Habu 70mm. Naturally, action cams don't do much justice, but DJI Action 5 Pro shoots good video. I'm going to now on start using dual 2.4Ghz and 900Mhz receivers for better redundancy. Thanks for your input.
I have a 80mm cougar and 70mm viper and both do not last over 3:00 mins without having to land so i like to land about 1:30 into the flight so if you need to go around you will have the amount of battery left however i believe this crash was from orientation lost very sad to see a new bird go in on a maiden hopefully you can replace it 😅 very sorry for the crash tho
@alexmullany thanks Alex for your kind words. Really appreciate it. I'm being advised by everyone like you to keep flight time 3 minutes. Orientation was one of the factors and also one of my brotherly friends who flies turbines and EDFs told me that my plane was stalled and it might have been due to half flaps deployed and lower airspeed.
I make several 3 min flights checking my packs afterwards once I have a base then and only then do I adjust flight times accordingly. 3 min pretty much standard on jets then go from there. Sorry about your loss and definitely to far out for orientation
@BillWaggoner-sk4ci Thanks for the nice comments. I did say a couple of times about losing orientation, but the video cam was DJI Action cam without zooming capabilities. However, my flight envelope is the same for all planes including prop ones.
@ModyKhan shame to see her go down like that, unfortunately I've learned some hard lessons like yourself. It's what we do after that defines us, I'm positive you'll be back up in the skies throwing out some great flights. I do wish that my vision could see that far out, good luck and get back out to fly soon
That is a shame but, as you say, all part of the hobby. My only advice would be to buy a flight controller, learn all about INAV and install it in your next plane. Not only is INAV great fun to learn, it will save you a lot of money, smashed models and heartache. Don’t ask me how I know! 😊
Thanks for the advice and the comment. Appreciate it. I have purchased the TD SR10 dual frequency for the redudancy. I've heard about INAV and flight controller but honestly, never bought them let alone used them. I guess, I would have to make sure the plane is more secure, resilient, and redundant, just like any workload people run on the CLOUD 😁. I am gonna delve into the INAV as well. However, the TD series receivers are capabale of Gyro stabilization. I am little wary of using Gyro, since these planes fly awesome without it.
Always in at 3 then check, bummer too lose one on a batterie loss.
@truenaturestormers2525 thanks for the comment. I've checked that the battery was still 30% following the crash.
Bugger,yip I keep them close, couldn't hardly see ,only fly bys was visable, anyways mishaps makes for a better pilot and was sad to see happen to a nice edf ,good luck for future flights , just dont tell mum you got a new one 👍
@ianr7176 thanks bud for the comments. My mum is in heaven. Lost her 30 years ago.
@ModyKhan oh crap sorry about that
Were you flying with too small a pack or is that the expected flight time of that EDF cuzz, it hardly seems worth it at that point.
You said it yourself - you lost orientation. Battery didn't die, the "lost telemetry" message was after (not before) the crash. It's happened to all of us. Sorry for your loss.
@Roj0307 thank you. Appreciate your kind words. I did lose orientation for a bit, and when I wanted to bring her back for landing, she crashed.
@@ModyKhan I've been rc'ing for 45 years, and have done the same so i feel you're pain but there's always a silver lining. Take care.
Safe mode has saved me many dollars, but, everyone is too cool to use it.
I've never set the safe mode and I have seen the videos, but not sure how to set it up. Do I have to make the servos neutral or do you have any video recommendations for setting up the safe mode?
Happens to us all, this hobby would be no fun if everything went perfectly all the time!
Yep, it does happen to everyone.
@@ModyKhan Got a remaiden of a broken jet coming up myself. Can't rule out the possibility of a crash ever, no matter how good you are and how well prepared you are.
Flying looking into the sun when doing a maiden flight is seldom a good idea!!!
Pilot sounded unsure of what was going on almost the whole time !
Battery did not die .You were disorientated and it felt like you lost control! That's my opinion !
You're right. Time of the day wasn't good, it was a late afternoon. If the sun's direction at our field were different, later afternoon flying won't matter. Thanks for the comments.
flying too far away , thats all. the avanti v2 is a great jet!!!!! good vid for all to learn from.
Thanks for your comment Steve. A lot of people are saying that plane was too far. To be honest all my planes including props, glow in the past, and EDF I fly within the same flight envelope. The video was shot by DJI Osmo 5 Pro action cam, which doesn't zoom so it also gives the impression that plane is too far. Thanks again for your comment and I appreciate kind words.
@@ModyKhan yeah i can understand that. Id say after looking back at the vid, i probably fly that far away when i get ready to land and then turn to final. I hope you get another one, I love mine!! I run Li-ion packs I make in it and get 6 min flights no prob.
Start with max. 3 minutes because an EDF is not very efficient.
With any plane I first fly a circle close to me, to check how it flies.
These are not beginner planes.
Thanks for a great advice. I'll follow it.
Even if youbpower the transmitter from the same source as the ESC the motor willstop but your transmitter and servos will respond and keep on working as per normal !
@@PieterErasmus-bm3ms Thanks. Did you mean receiver?
You mean receiver
As others stated yes, that pack seemed little and I was a bit surprised you say 4 minutes on the video. Better to go always for around 3 minutes and see. Also it is a good thing to reduce the cut off. A plane costs much more than a pack...
I always fly all my rc planes with a throttle timer % on my transmitter .
I never setup throttle % or timer
@ModyKhan
I think ur tx is a Frsky , if so you can input a timer on for ur model. For example, 2mins then set up ur throttle % on ur tx . When combined , your full throttle will be at 100% with the timer and when you pull ur throttle down half way down , ur timer will be 50% slower .
Throttle off ...0 % on ur timer..
Does that make any sense?
Or you could just put in a timer only and when it gets down to the last minute, it will give you a count down .
I'm using the original frsky Taranis 👍
First I agree you were flying way too far away keep in mind orientation is commonly lost when you can’t see your jet. I would slow down and stay in a closer flight pattern also the time of day matters the Aun can also cause visual confusion I recommend flying in the later part of the day

You had to mch fun. 😅 I fly mine for 3mins then land. 4000mah 6s.
@chrisneru6564 :) I don't fly full throttle all the time, which gives me more than 4 minutes
this version 2 avanti right out of the box can go 4 to 5 mins, this new setup stock is very efficient!!!!
That's why you never power your RX and servos from the esc! Use a separate battery every time.
Thank you for the comment. I did mention in the video that I ran out of the battery but I was wrong, that battery had 30% juice in it, which I didn't include in the video, however, I could have still had another minute on 50% throttle and bring her back safely. Honestly speaking, I take every experienced person's advice seriously but I have not seen anyone using a separate battery to power the ESC and RX on EDF Jets, they are all using the same battery all the time regardless of the miliamps.
I very rarely use a BEC with a separate battery unless it’s a petrol
I have come down with 2% in a 6S EDF and still had plenty of Rx control. Not ideal I know but can happen
@ModyKhan 30% doesn't mean you had that when it was flying , use a load meter to check lipos not cheap ones.
@@iansummers6945 I agree with you on it. Despite the battery tends to be below 10% it still pushes enough juice to get the control surfaces moving
@@Mikeylikesit1968 First off, give me some credit, don't just assume that everything I am using was a cheap one. I am using Spektrum XBC100 Smart Battery Checker & Servo Driver for RC for the batteries and there are other two good voltmeters to check the lipo batteries + the HRB is pretty popular brand and even ZEEE batteries never gave me a problem. My batteries were brand new, again, as Iansummer6945 mentioned above, that if the battery has 2% the control surfaces still deflect. I always balance charge my batteries before I get to flying field and Tx shows the battery volts on the screen as well. This crash had nothing to do with battery, it was my assumption which I was calling out about in the field prior to checking the volts in the battery.
Sorry Bhai, part of the hobby
Thanks bro. It's a part of hobby and it comes with its caviats.
What I can tell happened here:
1. You probably lost orientation. This is why I don’t buy this jet-the grey/red scheme gets lost in the blue sky.
2. Four minutes is too much for EDFs of that size. At the very most, three. And by the time that alarm goes off, you need to be already on final approach.
There are planes like the 90 mm T-45 that can give you only 2 1/2 minutes before you need to be already heading straight into the runway.
Great observation. Did I lose the orientation for may be a millisecond yes. Four minutes are too much, I agree with you on that. However, with 6s 6000mah battery and given the sheer power of this beautiful bird, the time of crash was over 4 minutes on my Tx and I still had 30% left on my battery, which could have given me at least another minute given my throttle had been most of the time 50%. However, I fly my Habu 70mm with 4S 4000mah, and it gives me over 5 minutes easily. As I mentioned to the other viewer to my channel that I take everybody's advice seriously and I will try to fly under 4-minutes. Also, if I am going to get the ARF plus model of Avanti V2 again, I will paint the bottom with black stripes to get more visibility.
Not to to mention a lot of F-16s in 70,80, and 90mm configurations, their colors are extremely blending with the sky that let alone orientation you lose a whole dang bird up in the sky...
@@ModyKhan There are F-16s that are painted ideally for visibility and still have true, scale liveries: the E-Flite 70 and 80 mm Thunderbirds ones (white top with red and blue trims, and black bottom). The new FMS 64 mm F-16 can be purchased with this scheme as well).
If I get the Avanti 80, I will paint the wing tips bright yellow. I have a Flitz 2 discus launch glider with a yellow nose cone and, while small compared to the size of the sailplane, it really sticks out in the sky and makes the plane easily visible even at long distances.
1 mile pattern, full speed… 1st shakedown…. What could go wrong
It's a half mile pattern, full speed momentarily not perpetual, of course what could go wrong..
My huge THANK YOU to all great RC fliers / viewers / and appreciating people for subscribing and liking my channel and videos. Happy Thanksgiving, and losses are a part of hobby. I have seen most experienced pilots lose their $15K jets and I can't fathom how they take those losses. Once again, Thank you all for your kind words, subscribing, commenting to my channel.
Your problem here was your loss of orientation, it happened to you twice, the sun in front of your fly path and the distance where you were flying didnt helped to much. Lessons learned here, pack the debris and try again with more wisdom and knowledge that this little bird have gave you. Grettings!
First off, the way you are trying to tell me is that you have tons of experience on flying these birds and your tone has some sarcasm in it which I do not appreciate it at all. You need to learn your own lesson how to keep a mellow tone and tone down a little when start commenting here on people's flying skills. Using the words like wisdom and knowledge, you have no idea about me or about my knowledge on various topics, so try not to be condescending here which can prove you to be an immature popper who is trying to just pop up. I have a great deal of experience however, the most experienced pilots are humans not robots, they make mistakes. I kept my flying in the right circuits, kept the plane below the sun to get in my eye. For your info that is not my first rodeo. Additionally, the plane was on my visual line of sight which I am sure you understand what I mean by that. I didn't even receive and VFR low warning on my Tx. It's not the lesson learned and I sustained the loss nobody else and that is the part of the hobby along with the risks that it entails. What I said during the flight about the orientation in my video, I still kept the plane in circuit, that battery was still 30% left, it's was the loss of signal during that time despite the plane was on my line of sight visually, and within the range, and it stopped responding to my gimbal input and took a roll, and plummeted to the ground. If it would have been a pilot error, I have no problem admitting that. No hard feelings here, just trying to make my point across. Happy flying.
That totally sucks…
Hi! Just got your video recommended. TH-cam is intelligent me having stalled the Avanti 70mm V1 and the Viper 70mm 15th ... I´m not an expert by any means, well maybe in crashing :P I would say you were flying far away for being this your maiden flight on the model. I would say to 99% you stalled her with landing gear out and flaps (extra drag) and that insane tail wind... So sorry to see this. I began to fly not even 2 years ago and this year Edfs. Although having a lot of practice I did stalled my 70mm viper doing a last take off to make a better landing and flying too slow downwind. I was near the sun so i had less time to react when she was coming down. In your case you were far away, maybe not high enough but you couldn´t see the plane position for recovery.... Just my thoughts - on my channel I have my Avanti 70mm stalling :S
Happy Thanksgiving to y'all!
Nice transmitter though
Thanks. Love this transmitter and newer version Frsky X20 RS is also out and really nice
Whatever the cause of the crash was. It's still pilot error!! Why fly so far away??
Boy, how judgmental you are. If a plane loses control and plummet, it's a pilot error. You are the judge of the judges and delivered your verdict that it's my error. Again as long as the plane is within the line of sight and if your hearing is in good condition, you should have heard me saying I see the landing gears come down. If you don't know what you're talking about, stop commenting on the channel of people who have common sense.
@@ModyKhan Than don't post your video if you, clearly, cannot accept the truth! As always. It's never the pilot's fault. Just like you! OH. I forgot. Just how is it possible to crash one of the easiest e.d.f. jets on the market? Too much of a e.d.f. for you? Try something that you can handle.
Just in time for black Friday.
Right, the price is still the same, no discounts
Sorry, bro.
Thanks you, buddy. Appreciate it.
Looks like you were flying way to far away and lost orientation.
I did lose the orientation temporarily. Upon bringing her back to landing, a friend of mine told me that since half flaps were deployed, it might have been airspeed that could have been the reason of stall and then it slammed into the ground.
Practice using your switches without looking at the controller. These jets can get away from you if you take your eye off of it for one second. Been there, done that myself.
It is not my practice for the last over 20 years to look at the Tx''s switches or the screen. I've not done that in this case or even in the past. Thanks for the comments.
Downwind takeoff - Not a smart move
How did you ascertain it was a downwind take off? During taxxing did you notice the windsock on the right top corner, and upon taking off did you notice the windsock direction on the left corner as well? Please make sure your observation is accurate before you put in such kind of smart@ss remarks. Quite an inept move, which speaks volumes.
Ppl should read ALL COMMENTS AND REPLIES and no one should have to repeat what they think happened. Its all explained in replies🙄🙄🙄
Don’t fly your whole flight full throttle, especially on a new maiden.
I was not flying it full throttled througout the flight.
Don't let the wife see it and order a new one 😉
@@JordanColeman-r8w lol, right. She already knows and ok about it.
Once again my huge thanks to all those members who provided me a very positive feedback, advices, liked my videos, as well as subscribed to my channel. Additionally, I had a lot of clairvoyants here with deep prowess of looking at the video at a glance and gave their verdict pilot error which gave me a pretty good idea about their flying experiences. Anyway, it's an old video and I came across this video, not sure what happened to this awesome Sukhoi SU-27 turbine jet and cost a pretty penny.
th-cam.com/video/aCA89eqCS3w/w-d-xo.html
A $25 FrSky voltage sensor would have saved your plane.
I have set up a voltage display on my radio. I did say that the battery died, but it wasn't the case. The juice in the battery was 30%.
Oh it died while flying. The voltage dropped to the point you had nothing left to power the servos and edf. That 30% is only after a resting period.
Couldn't see it
You meant you could't see the plane or you didn't see it coming?
You're flying It too hard and too long. I always keep my maiden short. To much wot flying.
I didn't fly the plane throughout wide open throttled, I did transition it but did fly 50% throttled as well. Also, I have learned and keep learning that these planes though they fly extremely well, but any plane has an inclination of stall especially when it does not fly with the the right speed, doesn't constitute full throttle but about right. I am continously flying my Habu 70mm and it's teaching me quite a bit.
Your flying too far away
