Finally got this far enough along to take a few pix. This is also Sterling Hellcat based with a foam wing and the rest of the parts traced from the kit parts, except for the plastic canopy that the kit features.
Radio installation uses the same low-cost Hobbyking receiver/servo as the MO-1 above. I did buy some extra receivers and servos and had no trouble with binding the new receivers to the transmitter.
I stuck the radio in a cutout in the foam on the bottom, with a plastic cover screwed over it. The battery is underneath the receiver in the shot below.
Also I will be using a slider which I haven't yet worked out, but will also use the direct connections to the bellcrank that Bill has shown. One word - I first set it up with a Sig 3 inch nylon bellcrank and then decided I had better pull test it. At about 35 lbs, the plastic bellcrank started to fold up, due to the offset load (due to the monoline buttons). If conventional leadouts were used, threaded through the bellcrank, I'm pretty sure that the plastic bellcrank would be OK up to the normal 20g pull test. Anyway, I went with a Fox aluminum crank - which I pulled to 90 something pounds with the buttons.
