I traded an engine for this NIB Picco .60. I'm waiting on it to arrive. Has anyone owned and flown one of these? I understand they are very similar to OPS's.

The Rossi header should fit since it has an inside diameter of 24mm and my Picco's exhaust port is 22mm in diameter plus the thickness of the rubber o-ring. I imagine I can try different o-rings until I get a snug fit.

I'd appreciate any info about this exotic Italian critter.

Thanks.
