The following arrived this evening from Steve Makish about his type 4 failures.
Orma Hello, Steve here. My crank was a 78mm scat. It broke across the # 3 rod (I think, it was so long ago) The crank was brand new and no mods were done to it. It broke at about 220 hours. Dan Diehl broke one on his type 4 engine also right about the same amount of hours. I also cracked a stock 71mm, but I found that out on the ground and not in the air. I rebuilt the engine again with a stock crank but had Steve Bennett put in his force one hub. I flew it for about 25-50 hours before I sold it to a guy locally who was building a kr2s. Strange sidenote. Last week at sun and fun a beautiful kr tri gear pulled in from Venice fl. We got talking and he was a real nice fellow. Come to find out he bought the guys project, finished it and is flying with my old engine (110) hours so far. He was not happy with the performance and was looking into putting in a corvair. funny how things work out. Hope this answers your questions, Regards, Steve
