[maxxdude1234]

just to report to you guys. Ground the shaft, works absolutely fine and holds the pinion nicely.

Just ran my bl maxx for the first time (2000XL/7018/18cells)...All I can say is wow!!! I was cruising along on asphalt in 2nd gear at about 10mph, jammed on the throttle (not all the way), and the truck just lit up. The front end rose off the ground, and the rear twisted round as the tires began to baloon, and I must have been doing over 30mph within a couple or seconds.

After a 5 run the batts were still cold (indicating they have hardly had to chuck out any current and still have loads of charge left), the 7018 was barely even warm, and the motor was fairly warm. From listening to the truck accelarating hard in 2nd gear, I think I can hear the slipper clutch slipping a bit. I'm running a stock slipper with 12pegs, but I'm going to tighten it all the way down - I don't do much jumping, so it shouldn't matter.

Thanks for all your help guys, and special thanks to mike for helping me out with choosing the right set-up and organising shipping direct from bk - cheers!! :D
