Full scale Corsair had a bent for such problems on take off due to the huge power: The enormous torque of the Double Wasp engine also made it a handful for inexperienced pilots if they were forced to bolter.

20ft was the altitude it reached, not the ground roll. Look at post #8.

unfortunately without a video no one here can really help and only speculate. It does however sound like a stall.

As I stated in original post, was perfectly balanced and ailerons were correct. Appreciate everyone's comments. Yes, without a video, it's difficult to determine. Thanks.

I bet the operator did the same as I did during a maiden flight on a TF P-51. The CG was perfect, all flight controls pre-checked before take-off. Full power pre-check before flight was good. Take off roll at full power lifted off around 150 feet, climb out speed more than enough for stable flight. At approximately 70 foot altitude the Mustang seemed to slow down then slow rolled to the left. I could not recover from the roll before impacting the ground. I couldn't believe what just happened when the take-off seemed just perfect. I then happed to look down at my transmitter and seen the throttle stick had been lowered to 1/3 throttle. Due to the excitement and nervousness of the maiden flight I believe I moved the throttle stick back to 1/3 without realizing I did it.


Was the FG90R3 damaged in the crash?

I had a warbird act up on me real bad on take offs.. as you stated I had the CG absolutely perfect according to the manual.... BUT. She was tail heavy and as soon as I added nose weight all the bad habits went away.. I’m just gonna throw this out there.. if you added any tail weight to that combo I can almost bet it was tail heavy.. and having a three blade adds even more prop torque to deal with.. my buddy has the same exact setup and you almost have to fly it nose heavy.. all warbirds in my opinion.. either way whatever the reason I’m sorry that happened it def. suxx.. that is an awesome combo and I feel your pain.. I had a Mitchell go in on the maiden I was so bummed out! But that’s part of the hobby I guess.. recover what you can and keep flying��

FG90R3 had very minimal damage. Hit on the wing when it went in, which saved the engine.

I bought a receiver once off E-bay (that was counterfit) and my 80" Bert Baker Zero rolled into the dirt after about 5 minutes of flying on its first fligh. Sent it in to the mfg and they confirmed that it was a fake and would loose connection and crash. Now I'm very particular about getting a genuine product

Did it have redundant power? Did everything work after the crash? Most likely a servo or a loose connection in the power supply somewhere.

A club member has the same setup on his. One time he took off and the engine died as soon as he took off. I will tell you for sure the airplane didn't crash to pieces. It landed and ripped off the gear only. What I am trying to say the airplane didn't stall so in your friend's case I would think there is something else going on other than engine speed. Either a sudden change in elevator trim causing it to stall, a bad servo on the ailerons, flaps or elevator. Maybe he had a flap to down elevator mix in and it was in the wrong direction or too much? Just thinking out loud.

I'm wondering if they were plugged in... reversed ailerons would have been responsive.
