When breaking in this new motor, I followed Traxxas break-in procedures
as closely as possible. However, shortly after starting every few
minutes I had to give the motor a break due to heat. Thinking the motor
would be better after break in, I installed a micro temp circuit (
http://www.venom-racing.com/instructions/vst/revo/index.htm ) and
followed through with the break in process. I'm now on 6 tanks of gas
(125cc) and still have a motor the triggers the fail safe circuit after
a few minutes of fun. The temp trigger point is set at 285 degrees F.
Now suspecting air leaks I found a rather large obvious crack between
two pieces of plastic molding that houses gears between the starter and
back of the crank quality. Good quality high temp silicon sealing the
crack seams to help but the motor is still overheating. I'm unable to
find any visual air leaks at this point but the motor still hits 280
degrees at idle. Should I send this Revo back?
