The plane at full throttle always pitched straight up. Pilot must had to hold it nearly full elevator down to control the climb rate at full throttle... stalling torque roll on take off.
I think it was combination of pretty strong wind comming from the right mainly ( not left )& low takeoff speed that created a stall made it easy for the plane to roll over & crash. But mostly must have been the wind...check your takeoff direction mate to be straight opposite to the wind...just my guess...
I could see by your frequency flag on the first flight that the wind was moving from left to right. That first flight was a downwind takeoff. I suspect the second takeoff was the same. I own the NitroModels 337 and this heavy plane needs the wind working with you. Longer takeoff, into the wind, and better matched RPM would have made a difference.
To set the record straight, the 337-Skymaster has a twin push-pull engines configuration (one in front to pull and one to push from behind the fusalage) , if one fail it will not effects the performance of the airplane, hence, its still has enough power to stay airborne..that was why the U.S air force adopted these airplanes during the Vietnam's conflict where the the threat of anti-aircraft was too great. Therefore, engine's failure wasn't the main reason to cause the crash.
For take-off on grass, I always have mine airborne at greater distances with full throttle. When the wings have enough lift, the plane just get airborne without much of pulling back the stick.. Just my share to you. Best regards.
Unlike the first take-off, there was a hesistation on the throttle at about 7:11 due to the bouncing, this could have reduced the airspeed needed for take-off on grass. Right after that, the pilot was a bit hash on pulling back the stick caused the plane lift off with high angle of attack without enough sufficient airspeed to get airborne..classic slow speed stall, one wing tip over and the airplane went into a spiral spin...no one could have got out of the situation at such low altitude.
it appears that you lifted off in ground effect not enough airspeed at takeoff and it tip stalled very common mistake with high wing loading aircraft sorry for the accident

It sure looked like it stalled. Its gard to tell the speed from the video but it appeared the engine faultered for a second and the angle of attack was a bit higher at lift off on the second takeoff. Its a heavy plane. Love the KMP 337. I have 2 of them..

Was the repair successful?

My money is on pilot error, sorry to see it, when your a flyer it hurts to see this happen, bad luck.

Bumpy runway, high winds and bad throttle management = crash!!! I was a very nice plane tho

Did you check to see if both aileron s were operating properly before take-off roll ?

I tell people all the time... DON'T FLY WHEN IT'S WINDY!!! This is why. Now I'll be telling people "DON'T TAKE OFF FROM BUMPY GRASS RUNWAYS!!!
Sucks...it was a nice plane.

was it ESM model? can you please guide me the CG of this model please?

That sucks. Sorry about the aircraft. Looks like it stalled - angle of attack too high with engine out I'd say.
Don't worry, I crash at least one every flying season...
