Ed: I am glad to see I was not alone in being unable to get my Wen-Mac 049 running long enough to fly. I think mine was on a Stuka and a Corsair but I whipped it around on short lines and it actually flew
until I got too dizzy and fell over. I must have had some of the very early poor running versions. I had better luck with my Cox PT-19.

Didn't I buy an OS engine from you ahwile back??
