Thanks guys this is good, Starting to look like physics at school, arghhhhhh, but I guess there is alot of physics in the forces acting on an airplane.

So now I understand why blipping the throttle works, accellerating the prop creates little bursts of torque to the airframe? Right/Wrong?

And the Diameter, RPM thing makes sense.

But I have also heard that increasing the pitch of the prop will speed up the torque roll, how does this work?

Reallity (that I have seen anyway), seems to go against the RPM theory, as the smaller the engine/faster the rpm, the less torque produced, ie little engines high rpm vs big gassers at low rpm?

Or is this an indication that the prop diameter is more powerfull than RPM in creating torque?

Or is this just a scaling effect at work here?

Thankyou,
