lorrylemming Posted July 31, 2022 Share Posted July 31, 2022 It's normal for brushed motors to get hot, max temperature is about 80°C. Anything higher will damage it. 1 Quote Link to comment Share on other sites More sharing options...

Nitroholic Posted July 31, 2022 Share Posted July 31, 2022 The LiPo battery is providing more power, which should make the car run a bit faster....but makes the motor work harder, so it gets hot. The 15T Firebolt is not the highest quality of motor, so when it dies ( as they all do ) it would be a good time to drop in a mild brushless system, which will make the car go better. 1 Quote Link to comment Share on other sites More sharing options...
