Hi all, I'm new to rc flying and am having a problem with getting my plane off the ground. I bought a plane from nitroplanes.com, it is a cap 232 and supposed to use a .40 - .46 size engine, which I'm using an os40la. I tuned the engine wide open throttle till the rpm's dropped then richened it up a bit. The props I've tried are 10X6 11x4 and 11.5x4. I must be missing something but can't figure out what it is. Too bad Realflight G4.5 can't have these variables to learn from.
