DKflyer : I had one of these Caps a few months ago . I had a Saito 150 on mine, I started with a YS120 " too heavy" then on to a YS 91 " too weak" & settled on the Saito. Man what vertical !! This joker would hold a hover at about 1/4 throttle , yes they hover & TR very well. I used Hitech 425bb servo's except on the rudder, it was a high torque Cirrus. I replaced all the hardware to Sullivan , tail-wheel, control horns, clevises. I moved the servo mounting tray to the back of the wing opening & glued it in there for balance with the Heavy YS. Hope this helps, Later, Rob
P.S. Get your motor & balance your plane as you build it , this might keep you from having to add weight to get it to balance later. If you go with the 120 Saito you'll most likely have to move your servo try back also. Later
