I've got the same setup as RC. I used 4/40 wire for the split elevator on mine. Only two flights so far, but no problems. Mine is slightly nose heavy and after seeing how she performs, I'm going to leave it that way. I too have 4/40 all around except for the aileron/aileron connection. The Saito 150 is plenty of power. I've been flying around at half throttle or so. I put some flourescent tape on the LE of the wings so I could see the plane better below the treeline on approach.
Great bird!
