Sorry for your loss. It was a beautiful plane. This is a classic accelerated stall situation. It's a high speed stall that typically occurs when pulling out of a nose down attitude too abruptly. You can see the left wing drop and the aircraft enter a spin.
OK: so how DO you fly out of this accelerated stall without becoming a lawn dart? Seriously. Left descending spiral, airspeed increasing: ??? Gas off - neutral stick and rudder - rudder opposite spin - pull up as wings get level - gas on - pray ???
Photographer followed rule two of photography - focus so tightly on the action so that most of the action is missed 0:01, also on the way to rule number one - when something exciting happens, point the camera away from the action 2:11
Wow, Really sorry to see this... It looked to me like you just lost radio contact with the model.. I suspect a control surface may have stopped working if it wasn't the radio... Did you ever fix it or get a new one... Did you ever find out what happened....? Just asking... Thank You
@@jyrrys If you mean the pilot had stalled the wing on the inside of the spin, then I agree. "Torn flow", separated flow, whatever is just translated aerodynamics about stalling a wing, right? No reply about radio failure, so I'm guessing it's a stall. Above I asked how to fly out of it and wonder if anyone can reply with actual facts. Keep flying!!!
Maybe, but I don't think it was slow at the bottom, just not removed from it's descending spiral flight mode, in which mode pulling UP only makes the spin TIGHTER and the nose drop MORE. Then there's that sudden stop at the end that causes so many problems.
This was not your fault. Its only a model and should be able to do anything you like with it. You were not flying too fast. One of two things happened. 1. Brown out - No comms or 2. Structural failure due to bad build quality. Seagull have absolutely no quality control. These are built for a price - not for quality. I have a list of all the things wrong with mine and it beggers belief. The engine mounts flex so badly you would swear that the engines were not screwed down. The vert stab was cracked around the base and full of filler, the elevators were different shapes and L/H was warped. The L/H elevator hinge wire was 2.5mm too close to the horizontal stab trailing edge. They couldn't even find a WWII pilot that fit. The wing cutouts in the fuse are oversize which allows the wings to pivot around the tube (have installed close fitting dowels to eliminate this issue). The undercarriage is not a bad design but they fell over with how it had to operate installed. Even RC Universe showed it as modified. One of mine had 7mm of fore aft slop when it was fully down. Very badly made. You could drive a bus through the clearances - talk about backyard manufacture. The level of instruction for the bits you really need information on is missing.
... or he screwed up gave too much elevator and stalled the wing. The instinct is to give more elevator in that circumstance, which just makes it worse. Give full throttle and get off the elevator long enough to get the wing flying before trying again. Its something to practise from a much higher than these low passes. In RC parlance that turn was at 'one mistake high', unfortunately he made two mistakes, starting a high speed stall and not recognizing it.
@@tonywright8294 How? The RC control module PCM radio signals make his fillings vibrate, and he can very carefully distinguish among various channels, servos, and radio-jamming feature. ;-]
I thought so too. Scale models typically are not designed to be flown aggressively. The crash wasn't because the plane failed structurally though. Tapered wings, if not designed properly, can lead to tip stalling problems.
