Thanks for that Da Rock, must have been one of those cyberspace glitches with the original thread then!
The servo connects to the top of the aerofoil as per the second picture. The nose of the aircraft is to the left as you look at the picture.
This is a semi kit, glass fibre fuz and foam wings. The rest you build yourself with reference to supplied plans.
Re the MAC point, a poster added to the original thread, that it was more important to have the pivot as close as possible to MAC. I was curious why.
.
This one uses a Dr. Mark Drela design, which when properly fabricated is quite good. In this instance, the pivot point was well behind the 25% mac. and the airplane had a serious stop-to-stop oscillation on the horizontal, leading to a total crash.
The drawing shows the proper way to have done this.
