mad4rc Posted May 2, 2015 Share Posted May 2, 2015 I have just recently bought a 1/18 scale 6100kv trackstar sensorless brushless system. The motor is getting very hot.The wire to the motor are getting hot too but only to the point where they plug in to the esc wires. It has done this from new. I tried running it for the second time and its still the same. So just befor i send it back i thought i would post it on here to see if there are any easy fix's i can do. Wishing to save on down time without a combo as mine is currently out of stock and dont want a slower one. My mesh seems fine no notching.I am running 17t pinion and a 66 t spur. The speed controller seems to be doing everything it should.Any help would be great. Quote Link to comment Share on other sites More sharing options...
NuttyProfessor Posted May 2, 2015 Share Posted May 2, 2015 Drop a few teeth on the pinion chap, how hot is hot though? Quote Link to comment Share on other sites More sharing options...

Geeze Posted May 2, 2015 Share Posted May 2, 2015 You don't say what you're running it in but if the motor is getting hot then the first thing to try is dropping a couple of teeth in pinion size. Quote Link to comment Share on other sites More sharing options...

Geeze Posted May 3, 2015 Share Posted May 3, 2015 Check with your friend what gearing he is running but it sounds like you need to gear down quite a lot. Quote Link to comment Share on other sites More sharing options...

NuttyProfessor Posted May 4, 2015 Share Posted May 4, 2015 You can get smaller pinions. Could be under or overgeared, you get the same symptoms either way where either the motor is topping out too quick or the motor is having to work its nuts off to keep it moving. A 380 can is ideal for a GT14, a 380L might be better for torque and heat though. normal 1:18 motors are 370 size so having a 380 or a 380L might be better just my 2 scheckles worth.
