YS Engines .60SR Side Exhaust Competition Helicopter Engine
Never blew up an engine til now. Piston shattered on 2nd tank of fuel. I sent engine back to OS hoping for a replacement. That was a month ago. I bought this just out of curiosity and I am not the first to have this problem. You can see that on various heli forums. Only buy this engine if you like wasting money. Otherwise I say stick to OS.
