After a winter of building my 40 GP Extra 300 the day finally came to see if all this hard work paid off. The flight went amzingly well. This plane needs very little elevator throw. Landings are a bit faster than my super sportster but that was expected. I was really worried that the TT 46pro would be a real dog on this thing, but i was pleasantly surprised at how the TT pulled the Extra quite well through the loops, climbs, spins etc. It isn't by no means over powered but it is a nice sized power plant for this bird. I havent used the cowel yet but will put it on soon seeing that the TT has worked 100% for the first 8 flights.
