This is a 4 cell chassis with about 7mm of adjustable front to back movement of the battery; it also can fit a THUNDERPOWER 1350 Mah lipo pack which measures 66mm x 34mm x 14mm. Flex plates with damper tubes provides control to the rear of the car. The flex plates are available in soft, medium and hard. The servo mount holes are slotted to move the servo to center in order to cut down bump steer.
Include is an extra set of standard turnbuckles to move your servo to the center position.
The rear pod was widened to 38mm to accept most motors.
You can fit a Novak Mongoose, Castles 26mm and the Epic Cobalt 18 motors.
Include is a modified Aluminum left side hub to accommodate the widened rear pod.
The 2.0mm thick chassis reduces flex and makes the suspension work. Also added to the chassis are two 5/64 holes for balancing buttons to ensure your electronics are in the proper place!
