You are joking right. You think the rrp gear are going to hold up. I had torn them out with a 7xl regularly. The 2250 is almost twice the motor the 7xl is. If you going to have a chance at a diff surviving you need the 1/8 diffs.
I know you want to go fast. I know you want massive power. If you not welling to spend the money for relible drive train. Please get a video of it.
Don't get me wrong though. I wish you the best of luck. The 2240 was powerful. The 2250 is more motor and you going to have more weight on it.
