When i got my chassis it looked real solid and heavy but its realy light. Probably not that much more than stock considering its aluminum and 1 inch longer.

Dooley, have you mounted your servos yet? When i did the screw holes for the shifting servo, evx, reciever, and battery straps were upside down, I had to put a screw in from underneath the chassis and put a nut on top so that it could hold the servo. Do you have the same problem?
