I have the manual, that's why I referenced the CARF specs on specified arm lengths and requirements. The manual makes no mention of which servos they use nor which arms they use (arms that are aluminum but not threaded to play well with pin clevises are not easy to come by). It does look apparent that the wing servos have arms that were cut down and new holes drilled though. I would just be interested to see which specific servos and horns other builders have used is all.

I've since found that SWB does make an arm that I think will work, should be able to cut these down as needed:

But even still, I like looking at build pictures. Figured with as many as have been flying there would be more pics of specific installs/layouts/etc.
