This all new chassis for your RX28SE Gen 2 changes the battery and shock mounting system slightly so that we can have more space to move the 340mah hardcase lipo fore and aft on the chassis, as well as allowing for our new 400mah LiHv battery to fit in the chassis in 98mm configuration.  This chassis also sheds approximately 5-6g off of the chassis in higher areas ensuring that while the chassis gets lighter, the center of gravity does not suffer. The kit is finished off with a new forward center shock mount that incorporates a band-less battery hold down that is more reliable and easier to use.
