I just felt like I wasn't keeping up with other racers. So I just went ahead and bought a 2200Kv and a 2650Kv motor (from China) so I will be switching out probably to the 2650Kv but the Tekno manual doesn't list that size motor so I wouldn't know gearing so I will drop in the 2200Kv because I have the pinion gear but bought a Tekno one cause I know they work.
