Putting the pinion on the very end of the motor shaft is bound to cause alot of stress on the shaft, especially if the truck is doing jumps and bouncing around. It would in all likelyhood snap, but that is down to the fact it is only 1/8", the common size used when it was designed. Hopefully the 5mm shaft upgrade will allow the pinion to be place further towrds the end of the shaft without risk of damage. Still, Traxxas were aware of this, yet said nothing- now there are a lot of people with motors that are no good for the new truck; you have to have a little sympathy for them and understand their predicament. I think a clever person with a CNC will need to design a new motor plate that is recessed in certain areas to allow the motor to be mounted further forward & line up with the spur better.....
