Yes they are to long.I will do away with them once I figure the right setup.I put new bearings in it when I built it to see how long they last,after 6 or 7 runs they still seem tight,but only time will tell.The tires wnd wheels are off an XT8,they have 14mm of offset.It's pretty much the exact size as my 3905.I have had a couple issues,the rear brearing carriers broke in 2 bashes,so I used some RPM,s on 3s with the slipper to tight it will twist shafts.But really I very rarely go bashing with a Pede and not stop before it's broke,so I'd say this is close to as reliable. in this vid I ended up stripping a spur,dang motor moved. http://www.youtube.com/watch?v=4xSknqCz-GA But I've bashed it like this about everytime.I have several short vids of it. Stock the Stampede uses different offset wheels,thats why the extenders must be different.I have the wide front that makes them equal length also.
