Yeah, I know. It may have moved the cg just a touch more forward, but it still flies very well. Maybe I needed just a bit more forward cg. Those are cool mods you've made, Joe. I've thought about doing the same things ever since I saw a Hangar 9 Alpha that someone in the club had done the same things to plus he put a .61 Magnum in it. It's a very cool looking and flying plane with lots of power and it doesn't even have the advantage of a semi-symmetrical airfoil like our planes. I thought I might try a .46LA in mine. Was it pretty easy to change from the 40LA to the 46LA? Also, was it a lot of work to take the dihedral out? Was yours the RTF or ARF?
