I raced my buggy last night it's zd buggy 1/8 scale 2700kv motor with a 3s 11.1v lipo 20c I believe. After first run it read 190degrees so I threw a fan on that didn't help for second run and I think motor is toast smells toast. I'm also using a 13t pinion gear. Any one have any advice on what my next step should be? I'd like to keep it so it can do the same speed.
Here are tips to try and cool it down.
1. Cut cooling holes in your body.
2. Put a heatsink on the motor.
3. Run it with the fan on the motor.
4. Gear it down. Chances are it's geared WAY to high. The lower you gear it, the slower it goes. But your buggy will run cooler.
5. Check the driveline and axle carriers for anything that could cause binding.
Heatsink, fan, cooling holes
