I flew a McCoy redhead 35 in OTS for several hundred flights with excellent service. I flew a McCoy redhead 19 for close to 1000 flights with no problem. I've seen one Fox 35 break the conrod, not the crank. Never had a problem myself with thousands of flights. I appreciate someone else getting all the bad ones. I heard somewhere there was a run of Greenhead 35's which had interference between the piston and the case, and that these were the ones which blew cranks.
