I liked mine with the BCMA 26cc. It had plenty of power for hovering and pulling out of a hover. I did not add any tail weight, but I put the rudder servo in the back and I put the Rx battery on a tray I made about 1/3 back from the trailing edge of the wing in the tail, (I think it ended up being about 8" or so aft of the trailing edge of the wing).

I'll try and embed a couple short videos of me during some first attempts at hovering a long time ago. The links are below just in case RCU doesn't allow for the embedding of videos.
