OK, here's a picture of the Skybolt. Reason I went ahead and posted it was it shows the way I use the horns that're supplied in the ARF's hardware. Reason I wanted to show that was it is a way to actually lighten the overall installation.

I cut off the bottom of the horns and simply slot the aileron itself. Epoxy the horn into the slot and you've got a very strong installation. Since you're not using but half the horn itself, that saves weight, but that's not the big savings. Not using the "other part" of the horn and not using the screws saves the most weight.

On your little airplane, you'd be getting rid of a ton of weight.
