My Sincere Apologies!
for anything bad I might have said or "thunk" about G-62's, or Zenoah engines in general.
I'm relatively new to the gas engine part of this hobby (4 years), so I have played exclusively with the "high-falutin'" electronic inition gassers like 3W, BME, and DA. I have to admit I was intimidated by all the problems my colleagues had with magneto ignitions. I like to come out, set up ,and FLY, not stand on my head all afternoon trying to start my engines.
Well, this summer I bought and re-engineered and flew a Ziroli P-61 with new G-62's already on it. I fully expected to have to pull them off and fit them with electronic ignitions, or replace them with DA-50's. I even ordered a big-Hog Miller RC starter, so I wouldn't tear my arm off flipping the props.
Well, Surprise! Surprise! The G-62's average about two flips to start, and run like gangbusters..20X10 3-blades @ 7,400 after only three tanks of gas! NONE of my electronic babies are that friendly.
I think part of it is about having spring starters that flip the flywheel through both spark and compression, which would be pretty hard by hand.
OK, so they're cheaper, have no batteries to charge, start easier, run great. Besides forward weight (which warbirds always need anyway), what's the catch??

There is no catch, it just appears to be a well kept secret that has eluded many of the newcomers to gas for a few years.
Those that are only interested in light weight have little to fear from Zenoah, but the long term reliability is something to be reckoned with. That's one of the reasons a friend has been running Zenoah's for the last 15 years, and every one of the engines he started with are still running after that period of time, several with many, many thousands of flights.
Oh, and by the way, that's the way they usually start. Just a couple of flips.
