[@cal-native]

Interesting comments here. Having flown RC off and on for 47 years, my two cents is that if he could pull off a halfway decent knife-edge, then he was skillful enough to pilot a high-wing, buoyant, stable aircraft like a carbon cub. It appeared to me to be some kind of radio glitch or perhaps a servo tray coming loose, as there was a simultaneous engine hiccup and down elevator spasm (maybe the engine misfired due to negative Gs). It was most definitely not a stall.

[@whoisjohngalt5258]

I agree 100%, been flying since the 1960s

[@user-rx8qq8sk9ydv1ce5ib]

Definitely not a stall

[@user-rx8qq8sk9ydv1ce5ib]

But maybe confused and made an up elevator rather than down.

[@josephhubbard5299]

It went in hard on a minor downline. Look like an elevator servo failure to me. Didn't see any pilot error on that

[@reignman0311]

Then why was the throttle on full blast when it happened?

[@FarmerFpv]

The first landing was super sketchy. To slow on the downwind? That makes no sense. He was in a dive. The elevator flutter is consistent with digital servo flutter from when your right thumb slips off the stick. The guy is a sketchy flier. Too much money not enough time and skill on that plane.

Radio failure. Engine was intermittently failsafeing right before impact

If there was a gyro inside, there ist the reason. to much gain brings flutter on higher speeds. Just easy as this

[@crgonzalez08]

Bull…. That was pilot error all day!

[@aidanbilger5753]

Gyro would have likely caused a higher frequency of oscillations but could have been the cause. However if you listen to the sound carefully you can hear a couple changes in RPM which suggest an intermttent failsafe. These rpm changes correspond with the pitch oscillations. Looks like he was flying jeti so it would have logged any radio issues. Hopefully he lets us know the true cause of the accident as im sure many jeti users like myself would be very interested in seeing if it was a radio issue

[@olekristianfollstad5913]

Looks like flutter on the elevator

[@icin4d]

Looked like more throw than flutter. Flutter usually happens so rapidly the control surface is destroyed. Looks possibly like the linkage let go, or control horn failed.

[@johnnichol9412]

Flutter is a rapid vibration of the surface, that was an up and down movement repeated three times.

[@scotabot7826]

Called a radio lockout. Listen to the "hit" on the throttle servo a second before the elevator pitched down. Easy to see and hear with the eyes and ears!!

Sorry to see that Regardless as to skill vrs plane, money vrs skill. (and so on) I said to myself I was not going to speculate in comments,. but... The approach seemed too hot and too aggressive of a descent for any kind of thought for a landing. Also the barn door flaps down made me cringe,. I thought certainly we would see a tip stall or wing drop. But he kept enough power in that, that didn't happen. If I was going to say,.. it looked like thumbs goofing up or thumbs still learning. The flight in general looked like a new pilot to me, that should not have been turned loose on a plane that nice. Starting with the 1st. taxi and then 6 foot take off. and the 1st landing was almost a crash.... my gut says the plane was nose heavy. That mixed with, be it pilot error or equipment error, spelled disaster at any rate. Sad to see such a nice bird returned to kit form. The guy has already taken enough beating losing this plane, Remember we all have been there and may be there again. Cheers.

Aerodynamic loads on the elevator were overpowering the servo. Or a servo failure. It was a slow up and down movement and definitely not elevator flutter.

[@Raptor50aus]

Looks like it went off the air (failsafe). Notice the engine change note too.

[@ChampPilotN4864E]

As a veteran pilot of General Aviation it appears to me it was an accelerated stall. The plane can stall at any airspeed or angle of bank. If the angle of attack is exceeded at any airspeed, angle of bank or position of the nose even straight down the wing will quit producing lift. In most GA planes that is about 18° angle of attack (angle of the chord line of the wing and the relative wind). I don’t know anything about servos or radio control aircraft but I have a great deal of knowledge about GA aircraft.

[@colebryant8832]

Radio…. Throttle and elevator glitching. Sorry to see that happen .

[@peterb6382]

He might have manually reduced the throttle to stop the elevator flutter

[@scotabot7826]

Exactly!! So simple, yet you have people on here writting thesis papers as to what happened. Man. it's so funny. These people kill me!!

[@georgelevin6134]

Lord I remember a newbie turning on his radio next to me my Chipmunk dived straight in. Looked very familiar.

[@MChronicleSword]

The pilot flew the plane beyond the limits of the electronics. Elevator servo drew too much power and starved power from the other servos - hence why the engine was intermittently glitching out. I don't think it's the radio or elevator's fault. Pilot flew too fast on a plane meant to be flown slowly.

[@shmaknapublar]

Any large scale radio install should have power distribution systems capable of producing more than any modern servo would normally draw and they also isolate each servo so any short will only effect that individual channel. They also run off of multiple batteries and receivers that can be isolated/ignored when a fault is detected. This is common practice now, with some radio manufacturers even offering power distribution and redundant features in their flagship receiver packages. My largest sailplane uses not only two main radio batteries and four independent signal sources/receivers, but I also run all non-critical servo functions through a completely separate power distribution system running on it's own power source. If a retract servo or brake servo locks up and completely drains the secondary power source, my flight controls aren't effected in the least. If you are flying something this big without multiple redundancies in your radio set up, you are not only a fool, but are endangering all those around you when your large scale model is powered up and/or flying.

[@scotabot7826]

Nope Sorry. Don't try and make something that's so easily obvious, in to something difficult!!

[@poochies0316]

how do you beef up rx power rails ?

[@cletusberkeley9441]

@poochies0316 One way i've used is to carefully run solder across all the positive (center pins) and also the negative pins, thus creating two rails that can handle greater current. I use heavier gauge wire to connect these to a UBEC or a dedicated RX LiFe battery. I may also use a 10000uf 25V capacitor at this point. Long servo lead runs like aileron and elevator I do with heavy duty servo extensions. I may also use a heavy duty "Y" lead out at those servos and plug 4700uf or 10000uf caps out at those points to buffer current demand at those servos to mitigate voltage drops at those points during moments of high current demands. I have this presently on my Bergen Gasser and Turbine helicopters, my 120mm EDF Ultra Viper jet and my new T-28 Trojan.

It never happened again with that plane. Fixed and flew it several more times without issue. Went back to that field again with another plane. Flew around fine made several flights. Came in on a similar approach this time with a larger Aero Works Bravata. I could clearly tell that something was knocking my radio out of sync. Another club member informed me that I was making a mistake flying in with that approach angle. Somewhere at around 30 to 35 degrees. He suggested several expensive options or just standing in a different location if I was going to take that landing approach. He also explained that having my antenna on my receiver extended straight out was not a good idea in these conditions. Fold it up 90 degrees.
