How much if any do your lipo's hang off the chassis ?.
It depends on how you mount them. The kokam's basical sit flat on the chassis with just a touch over. I mount mine in a plsatic case which goes over the side ~1/4 inch but still fits fine under the body and is protected in hard plastic. If I mount the kokam's on their side, they will not hang over the edge naked or in the plastic case.
