Yesterday I ran a tank of fuel getting the engine ready for the first fly ( when the weather let me do it!! ), and I was shock how hard the 91 pull turning a 14/6 prop. I didn't tac the prop to see the rpm, but the pull of the engine was sweet. I do think that the OS 91 II has tons of power for this bird!! Can't wait to fly her!!!!
RC gods, please give me good weather for this weekend!!!!
