This is an optional "F2" 7075 CNC machined, hard anodized chassis for the OFNA Hyper 8 buggy. This chassis is longer than the original chassis that comes with the buggy, and includes new front and rear dog bones, along with a new front upper servo saver plate. This is the version of the chassis that is 2mm longer in the front and 2mm longer in the rear, so the total length is 4mm longer, and the engine is also moved back 2mm. You can bolt this chassis directly onto your Hyper 8 buggy for improved handling in rougher track conditions!
This chassis is also stronger than the stock chassis that comes in the kit, and should help eliminate the problem with the stock chassis bending when landing from huge jumps.
