The same question bugged me in flying /hovering etc..
The force which would instantly accelerate the model -seemed higher than the force which tied to rotate the model.
The thing I kept coming back to ?
th accelerative force is a derivitive of the twisting force .
Y/N?
Only problem with that interpretation is you're watching the rotation of the model as a measure of the force.
The aerodynamic "power" of the model has a great deal to do with it's rotation.
A big foamy with lots of areas will rotate less than a little foamy. Neither are flying with any "power" in the aero parts, but those areas still resist being pushed around in all that air.
Put a 25kW motor on a big foamy. Hover it and then try to accelerate. If the foamy is big enough, you don't see much torque roll right? Might not even see one at all. Put a 150kW with it's appropriate propeller on the same foamy. Or trim off some of the foamy wing span and fuselage and keep the 25kW. And what do you see?
I'd say this test method doesn't suit the hypothesis. and change my observation to suggest that the angler hooked his shirt on the first cast
