8XL running slow

I had something similar happen with a 7XL. When I replaced the rotor, it came back to life.

I apologize for my lack of knowledge....when you say replace the rotor, did you have to replace the entire motor or is it something you can repair?

Yes, the rotor is the part that spins in the motor. If you have had it before and it was fine, then maybe you fried the rotor (rpm's kill Feigaos) if you were under geared?

Have you tried running it free wheeled yet?

I have just put the brushless back on and will do the free wheel test before bed. The RPM makes sense. The front center drives broke, so I was driving it 2WD. The temp was nml, but I am pretty sure the RPM were higher than normal. The motor is a Wanderer. I will get back with the test.

Zero, thanks for the input. I did the free well test and the temps were perfect. Turns out it was the EPAs - thanks for the suggestion Brian. I don't understand how they changed. I am pretty happy though, that costs nothing to fix! Thank you all again!
