8XL Overheating (Mamba Max, Losi 8ight, 4S) -
04.29.2008, 01:54 AM
Hey, guys.
So I have a Losi 8ight (Buggy) with a Feiago 8XL motor. The Mamba Max has the capacitor mod and a 25mm fan mounted on top. Also using a CCBEC. 4S lipo.
The motor has SICK power. Tons of speed and tons of torque. Problem is - the motor is getting REALLY hot REALLY fast. After 4-5 minutes of race-pace the motor comes off between 190-210f. the ESC comes off between 120-130f. Ambient temperature is approximately 75f.
I've read over and over "If the motor is hot and ESC is cool.. GEAR UP!" I started at 14/48 and had a heat issue on the motor. ESC stayed cool. I decided to try 16/48 and the problem remains. I am currently running 16/48 gearing.
What might be the problem? Am I geared too high/low? Could my motor be faulty even though it produces massive power? The drivetrain and motor spin very freely. Binding is not an issue.
If you have a similar setup (8ight, MM, 4S, 8XL) I'd like to know what gearing you use and what temperatures you come up with. Any info would help me.
Any help would be very appreciated. I've been trying to figure this out for a very long time now. I just don't have the money to plop in to a neu motor.
Thanks, guys.
