Are 4 strokes more likely to grenade like that than 2 strokes? It seems like I've seen more fragged 4 strokes than 2 strokes.
Having flown C/L combat, ratrace and Goodyear......... I've seen a lot of 2strokes go.
Having flown mostly weekend R/C for about as long, I can't remember any 4stroke in ruin that wasn't just a meltdown from the owner setting the sucker by ear. Certainly never saw a crank go and don't expect to.
But then, I've only seen a few R/C 2cycles ruined. One guy did most of them in. He likes to go fast. (He's the only guy I've seen trash an OS, btw.)
The crank in my photo above was about the only thing I salvaged from that engine. Other than dirty and a dinged threaded end, it came out fine. I can't beleive how tough they are.
