Im taking a good look at the rear end housing and assembly on the XO-1 for a large scale project im working on. The question i have is if the XO-1 rear differential/cush drive clutch is run without the center drive shaft will anything negative happen? Is running that complete unit RWD an issue?

Also can anyone confirm the hole spacing on the motor mount? Does that 1717 use the standard 25mm spacing on the mounting holes?
