SpaceRockMan,
Torque is the wrong term and this was discussed before you got here.
The problem that caused your crash, is the same as what caused that deadly crash at Oshkosh, a couple of years ago.
It is not torque that causes a plane to veer off its course, during the take-off run; but the prop's spiral slipstream, hitting the fin and the rudder on one side...
Because of ground deflection, with the tail low, hugging the runway; the bottom of the slipstream hits the fin and the rudder from the right, requiring left-rudder to correct.
Once the plane gains some speed and the tail rises, it is the top of slipstream that hits the rudder and the fin; but now from the left! This requires a force reversal, because now right-rudder is required, to keep the plane tracking straight.
This confuses newbies, even to the brink of hurrying the take-off, ground-looping and crashing their model...Or their full-size plane.
I am sorry it had to happen to you.
Extending the take-off run a bit, to achieve greater speed, is the solution.
The P-factor is another issue... When a plane climbs out after take-off, it is at a rather low speed with the nose high.
As a result, the descending blades of the prop have a higher eventual angle of attack, than the prop's rising blades.
As a result the plane tends to veer to the left during climb-out, requiring right-rudder input from the pilot, to fly straight...
Dar,
I live close too Oshkosh, and was there that day. That Mustang crash was caused by two P-51's that were landing at two different speeds. The trailing mustang was a modified P-51 and it was landing much faster "still airborn" when it ran into the back of the leader which was allready on his mains.[X(]
