Car came with a 13/56 gearing. It also came with an optional 19 pinion.im running a 4000mah 2s. I put an 18 tooth pinion on and love it, however it gets hot. Esc was 170 the motor was 240! I bought some other smaller pinions to try as well but really like the performance with the 18. I picked up a motor fan that I haven't installed yet. And from what I understand you cannot go to a bigger spur? Any suggestions?
Maybe upgrade to a better motor+esc combo such as a Castle Creations system.
Slash 4x4, Rusty VXL(project), Slash 2wd(project).
Buy a new motor. Anything that hit that kind of temp will have some damage.
Cheap, Fast, Reliable. Pick 2.
holy cow Bitties that is one toasted motor, I think the motor temp limit is @ 180. do what most People here do, upgrade to MMP/2400. maybe try 15t pinion and ease off with the throttle, don't drive with full throttle for such a long time, let the truck rest and cool off.
by the way welcome to traxxas forum and to this addictive HOBBY
humay has left the building, peace.
I have a viper esc and 3900kv motor to try, but it's at Viper currently for warranty. A magnet in the motor cracked. Hopefully I will get it back soon and ill try it out.
