That, always made me wonder. I've also heard stories like that, but none of them were second-hand or first-hand sources. Always, somebody quotes that from long distant sources which they also don't know about.
So, is that really true? When someone engages full throttle directly after turning the engine on, will the torque just flip the plane over?
Somehow, considering the weight of the plane, I don't think torque force, even with 2000hp engines, is itself enough to flip a plane standing still with three gears instantly.
From what I imagine, I gather that it is the following results of a full-throttle take-off run that causes the plane to fall under the danger of ground-looping, and that, is what causes the planes to 'flip' - as in the case of the Beta5 Spit9(although, this was due to a bug).
Can anyone comment on this?
