rwf1953,
I've been keeping up w/ your posts regarding the CA hinges, and appreciate the knowledge gained by other's experience. I still have my GP Pitts in the box, and until your posts, I was planning on using the CA hinges. I now will use a pinned hinge. This will be my first gasser.
I suspect the failures are due to the gassers vibrating more than smaller single cylinder glow engines. I was just talking with one of our club members today that refused to try gas because of (among other things) the violent shaking of the engines and abuse it can cause the airframe and radio equipment. He likes the huge multi-cylinder glows.
I am still putting the Fuji 50 in my Pitts, but for sure will use better hinges.
Thanks for all the knowledge you have shared regarding yours!!

I think Pilgrim has it right on this one, I have not flown with gas yet as the ones I see at our field (20 t0 50 CC) vibrate an order of magnitude worse than the big bore glo engines. With most of them if you watch closely as the owner runs his engine up and down the RPM range you can see points where one or more of the control surfaces go absolutely nuts turning into blur that you can hardly see. When a gas flyer says his engine is really smooth, he is not talking about smooth compared to a good glo engine, he is talking about smooth compared to other gas engines. Just as I see it. [8D][8D]
