My collection of OS .15s with cracked crankcases has led me to wonder just how slow and survivable SSC really is. With a rigidly mounted engine on the front of a 40 oz "piledriver", the engines have been coming away as junk after a crash. An easy to shear mount has got to be the answer. The glow .15s are a little bit too hot for this class to be really and truly "SSC". Diesel .15s give enough power for combat and drop the speed down to a level that is truly "SSC".
