Project 4X: Shorter chassis stiffenerFor more torsional flex, a quick stiffener can be obtained which basically acts as a connecting point for the servo mount therefore the front side topdeck stiffener. It can only be found in combination with a topdeck, either this new dual straight topdeck and/or standard flat topdeck. In addition saves a considerable amount of fat. The quick stiffener is of course appropriate for the latest topdeck stiffeners, nevertheless a 4mm shim can be used involving the rear topdeck stiffener and motormount in this instance.
