RE: Zenoah G-62 or DA 50
Silversurfer
My Z Corsair flew just fine with 5 extra pounds of "ordanance" with a G-62. (40#) It flew just like any other heavy warbird. I wouldn't exactly say it would do a scale loop from level flight but.....you know what I mean. Landing at about half throttle was cool, just a little faster than usual. Also with a 22-10 prop.
BTW, RC Ign straightened my crank years ago and it never ran better.
I wonder if a DA can withstand 20 prop strikes in a year and still run fine??? Yeah I was just learning about warbirds then.
