I've got a second hand, but basically new, xtreme carbon fibre brushless maxx chassis. The chassis is awsome, and my truck now handles like a 1/10th on-road.

However, for some reason I keep on stripping spurs very very very quickly (about 2 hard accelerations). I'm using the stock slipper/spur set-up with 12 pegs, and I'm running a 2000XL on 18cells (ie. gobs of torque). I think I've narrowed the problem down to the mount mount; as far as I can see its twisting under the torque, and hence altering the mesh between the pinion and spur. I'm using the motor mount in this photo, http://www.xtremercracing.com/Images/BLBSIDE.jpg . I don't want to use the stock motor mount, because that will raise the CoG a lot.
I wonder if using the strobe slipper with a blue delrin spur would solve this problem, or if anyone else has had this problem and how did they fix it?

Thanks

Id say use a strobe slipper with a ofna spur, and youd need a mod 1 pinion for the motor, that should work for that powerful application.

k, thanks for the quick reply. Think I'll email xtremerc aswell to see what they think.

ok, no problem, but if you want the greatest gear mesh , and longest lasting setup than id use the strobe slipper, and ofna spur, maybe theres better but i havent seen any other gears out there.

Thicker motormount. Even with a strobe slipper you might still have the problem of wearing the spur's instead of stripping them.

Nice clean chassis, me like it.

might want to consider adding a brace. i dont know if you can fabricate things or not but just by the looks of it a rear aluminum brace off of a 1/8th scale buggy might work with a little modification.

Yeah i'd agree that mount looks a little thin although the basic xls aren't heavy.I think squee's suggesting to triangulate the plate itself with a brace which is a good idea,(a buggy chassis brace or some turnbuckes),or you could make a thicker mount from some 1/4" aluminium angle or you could make a holder for the rear of the motor.BK make these(see pic) which makes it alot easier.
I also recommend the mod1 strobe slipper.
