This time it's not the usual hole in piston. My big end on the con rod let loose and sent shrapnel all through my 2 gal. old os70. Was fly around lightly, and it just flat out stopped. Auto'd it in safely and packed it up. Got home, tore it down and saw that I'm out a whole freakin motor. Engine was mounted in an xspec with 9.3:1 gearing. Main rotor speed was about 1800. Engine was never lean, I was still tuning it. Never overspeeded, WTF? I've used many motors and this is the first one to ever grenade on me. What's up OS?

Nothing is ever so bad that it can't get worse

Look at it this way!

look at it this way, at least you managed 2 auto ur heli out safely without any damage 2 ur xspec.

i'd be much happier goin home with an xspec and a busted engine, rather than a busted engine and a pile of smashed xspec bits.

not so bad wen u look at it that way huh!
