Just changed the motor on my pro-pulse, it's a 17T trinity mini monster. I'm still running the stock esc and the motor has a heat sink and fan mounted on it, i'm running a 13T pinion and 54T spur and have observed no overheating. The problem i'm having is glitching, the car just goes WOT and stops responding to the Tx.
The stock esc is rated at 80A. i'm sure my motor doesn't pull that much current. I also noticed that sometimes if i touch the tx antenna i get WOT and when i let it go it stops. I did notice the glitching started after i change the motor though.
The esc is just behind the motor, didn't try moving it. I just made sure it was as far as far away from the receiver as possible. So the esc being close to the motor causes problems? It's in the same place when i had in the stock motor.
