I'm running a gtb 7.5 in my bj4, orion 4800 lipo geared at 15- 72 and after 8-9 mins it thermals. I've opened up the body to allow more air and it still does it. I'm running a fan on the ESC so it runs cool. I've concidered a larger fan between the motor and ESC to draw air accross the esc and past the motor.Any suggestions here would be much appriecated.
Thanks, Be Blessed, Kingskid :thumbsup:
anything smaller than a 15 pinion, the motor rubs the center oneway. If I'm going to gear lower, I'll need to go bigger on the spur gear. Thanks, I'll give it a try. Be blessed :thumbsup:
after some research, I decided to add an 1.5 inch fan between the speed control and motor(eliminated the original fan). At 16-72 it runs at about 150 after 10 minutes. They tell me the sintered rotor drops the temp about 30 degrees so I just put one in. Won't get to test it until saturday. I'll post my findings for anyone who'd like to know. Be Blessed
great, kept the temp under 150 even after 15min + runs. Power is MUCH smoother too. Best setup I've EVER owned. I would highly recommend the rotor in any BL setup. Be Blessed :wave:
