Ah I see. Then I can actually use a motor that's a traxxas replacement like the .19t from dynamite or the os .18. What motor would you actually recommend me trying that isn't overly expensive? I just want to stay around the kind of power this 3.4 makes compared to the recommendation that losi said which was to use a .15 os motor which is definitely not something I want to mess with. Would a piston and sleeve from a different motor work? I want to explore all kinds of options before anything does happen to this motor since i haven't been in the RC world for that long and am trying everything i can to get most power out of it without killing it so I'm keeping it rich for sure.
