I remember now RVM. Shame about your 82. I hope your new one gives your plane what you want. As far as the props. I have not put a tach on mine since I broke it in. The Zinger does pull the engine down more than the APC. At least it sounds that way. I am baseing my opinion strictly on how the plane feels in the air. Mostly how it reacts from a hover. Or how quick it will get in a Waterfall. The spool up is what I am after.
