be sure to dremel the rear hole some more on the body if your putting it on a 1.0. although its ovaled already, on the 1.0 the rear mount sits right at the front of the hole. since the 2.0 is 2mm longer the rear mount sits right in the middle. i found this out the hard way, after a few bad jumps with my car landing smack center on the chassis. the flex ripped my 2.0 body around the front mounting hole.
