Using AFSD on this aircraft is very interesting, Massimo has set up an unusual propeller set of graphs where the efficiency of the prop is virtually zero at zero speed & low revs. Not only that but the engine sound seems to be higher in revs than one thinks. Never heard a Rotax in reality so that might be a misleading route to follow. So one does not get very much thrust until more than 40 HP is reached, after that it then accelerates very well.
I note also that the quadrant in the VC has a label for the handbrake, but the lever is on the instrument panel. I have added toe brakes at 50% & reduced table 1101 braking strength as an idea.
One other funny - throttle set to 55% gives rpm of 5500, and any increase of throttle does not change the rpm indication, but the sound does increase.
I would therefore say that ground friction is not a problem, its in the engine/prop parameters.
Is the prop a Constant speed unit? It has a very narrow pitch range (19 to 20°)
