Nick: I could not install my flap servos as shown in the instructions.
When bent the pushrod would hit the top of the skin and the supplied
clevises were too big and long. Because of the supplied clevis length the
bend was too far back to function. I cut away the TE spar but still did not
get sufficient clearance to work. The main problem is that the screw in
flap horns are too short. They need to be 6.5 mm longer. I cut the top of
the horns off and silver soldered them to a section of 3mm screw from which
I cut off the head. The silver solder I used is not the regular stuff that
will not work. I used 93% silver. Flux used is borax (Boraxo works) I got
my silver solder from a welding shop. It has 70,000 pounds per inch yield
strength. Then I used a section of straight pushrod with Sullivan clevises
which are much smaller. I still had to cut away the TE spar for clearance.
Since I lengthened the flap horn I had to lengthen the servo arm so it now
rides above the surface of the skin. Thus I had to cut a slot in the servo
cover.I think Vladimir just didn't engineer the flap servo installation.
I think he made up something he hoped would work and threw it into the
box.
When I tried to install the pushrods for the V tail I realized that the tail
cone would make this nearly impossible. So I cut the tail cone off and
taped it on after I was done. Glad I did this.
Finally I found that the instructions for installing the aileron horns don't
make any sense. I reshaped the horns so that the holes were over the hinge
line and glued them in at a height that made sense. I could not figure what
the picture showing 6mm height was supposed to show.
Those were my main problems. If you have any questions don't hesitate to
contact me. Or call me. During the week day call my cell phone
314/477-6778.
My many calls to Barry Kennedy for help over a long period got me many
promises but no help whatsoever. He promised to call Vladimir, contact
other builders, etc but never, never gave me any information.
I flew the plane yesterday for the first time. It flys beautifully. It's a
keeper.

I just finished assembling/building my new Graphite 2. I ran into
problems installing the flap servos/pushrods. If anyone is interested in
how I resolved/fixed the problems I'd be glad to share my experience.
Online or off depending on how you respond.
