BTW. IF YOU CHECK THE HP RATINGS BETWEEN THE G-62 AND THE QUADRA 50 , YOU WON'T SEE TO MUCH DIFFERENCE. I HAD A 20X10 ON MY 50 I THINK
Well OK Warbird_1, but I have first hand experience with this engine and like I said, I'm so impressed with this engine and it's performance, I bought anther for the Mustang....
I'm busily installing a Zenoah GT80 w/CH in a Ziroli Corsair at this time. I had a Corsair with a Sachs 4.2 and it did well, but I always hated the huge hole in the cowl for the carb and muffler, not to mention the fact that the engine was offset off center to fit such that i could not use a dummy radial....
The point I suppose I'm trying to make is that there's alot more to selection of an engine for a Warbird than meets the eye....I find that the biggest "turn off" to a gasser in my selection process is whether or not the plugs stick straight out of the head, or not. I get real tired of trying to fit engines in tight cowls because of plugs that are installed 90 degrees to the top of the head.
The ZDZ Single I find makes a good fit in many such designs that would ordinarily be fitted with a G62, Q75, etc.
