I think a Saito 100 would have been a better choice. Even with 3 servos in the tail, sheeted horizontal stab, and major reinforment of the tail boom, my SS120 is still wayyy nose heavy. I'm running out of ideas of adding useful tail weight. I'll get a heavy tailwheel assembly and see if that will tilt the scale a little. If not, I may have to sheet the fuse sides and top of horizontal stab, too.

How did you get it to balance with a 180?
