Has anyone here ever upgraded the xtreme w/the titan 12t 550 and xl5 ESC? In general, the shaft is longer on the 550 than on the stock motor, and I'm afraid it will bang on the other side of the transmission, opposite the mounting hole.

1)Does it need to be cut? if so, how do I do it w/o damaging the shaft?
2) the shaft on the 550 has a stop (for the pinion) that is further away from the body of the motor. does this have to be ground down, or should I just turn the pinion w/the set screw on the outside?
3)Do I need any mounting rings or anything else?

Thanks for the help!

PS: sorry but I dbl posted, since I didn't know which forum it belonged in....my apologies in advance.

If you flip the pinion, the gears may not line up well. I would do what this guy did; use washers between the motor and motor mount to keep the shaft from hitting the gearbox wall.

Thanks for the reply. I had seen that video but didn't know if he used a washer or motor mounts. Thanks again.
