Status: offline 		Each Zenoah I've owned (actually any gasser)....Pennzoil 40:1 from day one, properly tuned, properly cooled. Standard approximate 12 minute flight times, with full cool down in between flights. Breaking in the engine is more about heat cycling than it is hours or number of gallons. Just tune it, cool it and heat cycle it.

Status: offline 		A 22x10 prop, Penzoil at 40:1, proper cooling, tune the carb 100 rpm rich, fly the snot out of it (lots of throttle changes).
No long torque rolls or hovering for the first few gallons

DING! DING! DING!

We got a winner!!! Concentrate on the "40:1" part and the "fly the snot out of it" part. I dare you to break it.

Status: offline 		The G-62 is one tough engine, I have two of them. Wal-mart oil would be fine as long as you follow the suggested mixing ratio on the label. Tune the engine and fly. It is much more likely the engine will be damaged in a mishap than anything else.

Status: offline 		Would a 20" prop be ok if ground clearance is a problem? I'm not too worried about having enough power. If not, I'll have to find a longer landing gear for my Big Bee. I'm preparing for the first flight next week if all goes well.

It's a little small. Might work.

The engine will love it, your neighbors might not. You should be in the high 7000-mid 8000 range

Status: offline 		Course with the smallest prop you can drill and fit you need the cheapest breakin oil you can get yer hands on. Or did I miss something.?
Don't mind me, just muttering, lets see, 20x10 prop at 85ish hunerd rpm on whatever oil walmart sells at the cheapest price. Sounds like a hoot! in progress. Then figure the feller doesn't really have a clue bout tightening, balancing, picking out a good strong, prop. But hey! What could possibly go wrong?
