RE: GT-80 IS THIS A GOOD ENGINE
I have a GT80 in a Hangar 9 Extra 330L. I run a 24x10 Fuchs prop and get 7300 rpm. My plane weighs 29 1/2 pounds ready to fly and the Zenoah will hover it a bit over half throttle and will accellerate vertically from a hover. I have about 50 very smooth running,trouble free flights on it. And it keeps getting better and better with each gallon of fuel. In other words................... I LOVE my GT80!
