RE: GP PT19 on Zenoah G26/38???
I think the 90 4 stroke may be only good for scale flight at upper end of the throttle. 120 4 stroke I can go, but the G26 cost lesser than 120 4 stroke over here!
Anyhow I wanted to try out gasser and see how things are not to mentioned fuel expense on glow with 120 size!
