Well, the CG is fine, maybe a tad tail heavy. I'm not going to use flaperons, but actual flaps that came with it, but they were locked. Its certianly not the idle, as I had a few deadsticks, and it still came in fast. Im using a 11 by 6 apc prop with an os 46 FX. I also don't think its my approach, because if I try to make it longer i will need to add throttle to prevent it from stalling.

Since I just got the hardware, I think its worth messing with them even if I get good landings without them.
