ok so im pretty new to this.
I bought a ECX Ruckus truck. I ended up upgrading the esc, the motor(t12) and to lipo batteries with the advice of local hobby shop.

The first titan motor i fryed due to not breaking in properly and running the esc on niccad setting. Oops.
THe replacment T12 i broke in via the water break in method. This motor lasted only about 2 runs totaling about 30 minutes.
So i went back to the stock motor and fried this motor after 30 minutes.

I was running 23 pinion on the t12 and the stock 18 pinion on the motor it came with.

Why am i burning motors so quick?
