Of course they will, Darin. But there is still the possibility that e.g. there
is a slight warping in one of the flaperons. That would affect the banking attitude
because, as I wrote, using a small trim tab on my left flaperon helped.

Darin,
Yep....You are not alone in the "I'll adjust one aileron..." scenario! That is
a very common mistake. :)
After I responded to your original post I found where someone had started a second
post on the same thread (I hate it when people do that!). It makes a thread
hard to follow and clutters up the Forum. OK...I'm off the soap-box! [Laughing]
Anyway...It sounds like most things were already covered. Yes, You do need to
determine whether it is a heavy wing or yaw. Your Ball indicator needs to be
where you can see it and easily determine if you're centered or not. This is
something that will change depending on your power setting and airspeed. I ended
up with a small trim tab on my rudder and set it to center the ball at my
"usual" cruise speed.
I can't speak for the 7, but on the Series 5, you don't want to stall it in an
uncoordinated configuration! That can be really bad on short final...or at low
altitude.
You have gotten some great advise from folks on this Forum. I look forward to
hearing about exactly what is causing the problem. Good Luck!
Travis :D

Darin,
As Lowell mentioned in his reply I too cured my heavy wing by adding a
rudder trim tab. It now flys ball in the center hands off when you can find calm
air. (rare)

Me, I would elongate the holes using a Dremel with a burr.
If you haven't covered, I'd consider replacing the thin plates with
tubes, similar to that on the horizontal. Then you can use
polyethylene bushings on all surfaces.

Simple fix, use a drill and reamer and go up to the next size larger bolt
and rebore the bushing to work with the larger bolt. If you can't do that
then you'll have to weld a new tab on.
That's the only things you can really do to fix it.

Jeff

If you do go to plastic bushings use Delrin, or better yet PEEK, Nylon
will wear out very fast if used for elevator bushings. PEEK is very
expensive, Delrin is probably your best choice.
You can get the bushings from McMaster Carr http://www.mcmaster.com

any bias between left and right adjustment should be toward increasing washout
rather than washin.

Hey guys.. lets not confuse the Model IV elevators to the 5 and newer...
Jorge,
The simple fix is to open the hole slightly... Can most likely be
done with a reamer. When the elevator tab is bolted on it will be up
against the inner bushing in the stabilizer and be just fine.
Fly Safe !!

John -
That would work, but it would not be acceptable from the accepted practices
point of view, since then you would have a hole larger in diameter than
the bolt.
Obviously it won't be a serious problem, but I think going to a 1/4 dia. bolt
would be a better solution. That is if it is like a series 5 which uses bushings.
Regards,
Jeff

Travis,
You are right, the flaperons will simply find neutral...I thought of this
after adjusting them the first time. Don't really know what I was thinking
when I made the adjustment...I have moved them back and now plan to do a
little more investigation to determine if it is a bank or yaw issue.

Hey Mr. McBean,
How was Oshkosh this year? Was the Kitfox the hit of the show? :-)
