Tried today the new FM 422 and I must congratulate for the excellent work done by Hobbywing now on par with Tekin both in speed and acceleration with optimum temperatures of the engine.
I have tested various motor and SS Novak Ballistic pro, pro-GM and 17.5 Feigao all with good results: excellent performances by everyone.
We did a comparison test with a friend with Tekin and the benefits were actually identical.
Consider that with 17.5 I was much faster than across the Track to another friend of mine with Speedpassion 2.1 (with standard FM) and 10.5.

Thanks Hobbywing
