I am hooking up the flap horns and I noticed that both flaps stick up about
1/2 inch higher than the ailerons.... I guess the silver lining is that both
sides do it... Any thoughts on this? Has anyone else seen this?
Sorry for large pics.

David:
There is a lot of down force on the ailerons in flight. If you put
pressure on them with you hand, they will drop quite a bit. In this
configuration, flaps will help overcome some of the nose down pitch
normal with a high thrust line, especially the mkIII and a high
powered engine.
Mine are adjusted very similar.

Bummer, hate when that happens!
No easy fix that I know of.

Hi Gang:
I was assuming it was the trailing edges of the flaps that were
sticking up higher than the ailerons.
Maybe David is talking about where they hang on the hinge line.

David, I adjusted the flaps using the threaded connectors on the pushrod ends to get the trailing edges of flaps and ailerons in line. Kolb doesn't use a left hand thread on one end so that it acts like a turnbuckle (at least they didn't on mine) so you have to disconnect one end to adjust them. Also make sure the flap bellhorns are installed per the plans. The guy who built my airplane apparently didn't understand how to align them and when I got a touch of aileron flutter one bellhorn got into my nice new Warp Drive and took out $500 worth of prop blades in short order.
Which leads to another suggestion, make sure you install the aileron counter balances. If they didn't come with your kit, call Travis today and order a set.

Looks like a hinge line problem to me.
Requires removing and reattaching the hinges.
This problem happen when rivets are set and are not exactly on the
apex of the tubes they attach to.
It is very easy to make this mistake.
I always first use a few aluminum rivets to attach each hinge and
double check the alignment before final riveting.
Replace the aluminum rivets with steel when alignment is confirmed.
Trailing edge no big problem.

Thanks John and Richard.
I have a prop extension so my warp should be fine, but I understand the
plans anyway.
I do have the aileron counter balances. No instructions with the counter
balances. Should I just drill out the outer aileron ends and slide them in
then adjust the slide out till the aileron is inline with the bottom of the
wing?
I'm less than a month away from first flight and closing fast. I'm going to
start the engine tomorrow.
