 |
|
The time has come for me to squeeze the right aileron trailing edge to try to correct a heavy left wing. Can some one give me an idea of how much to squeeze? I gather it is a really small change that is required.
How do you do it? With fingers? It seemed to me that a couple strips of wood a few inches long squeezed with the fingers will do. Iplan to do about 1/3 of the length of the aileron on the first try.

Hi Tom,
I agree - proceed with small amounts of squeezing and test fly after each adjustment.
I used some thin strips of wood and the "bending Pliers" that have the 3-4" lip for bending metal flanges. I used the wood strips to prevent the metal of the pliers from denting the metal. I think I squeezed about 4-5 locations along each aileron.
If you over squeeze, you can apparently place a board against the edge and hit it (gently and carefully) with a mallet to "swell" the edge back out.
I did mine back a number of years ago and it flew wings level afterwards. Be advised that if your paint is old or brittle it is possible to knock chips of paint off the edge using this process.

Tom,
I tried various methods and am sorry that I did. I saw a minimal improvement in wing heaviness and to not like the invertible ripples created in the trailing edge of the aileron. I was also worries about over-radiusing the trailing edge. I really wish I had just installed a simple trim tab instead. Adjustable, looks more professional etc...

Before you squeeze anything, have someone else that you have confidence with check your rigging.
All the RVs I've seen with a heavy wing problem were rigging related. Typically one aileron is mounted lower than the other, the gap betten the wing and aileron is different between wings, one or both ailerons are not parallel to the wings, or an aileron is mounted lower at one end than the other.
Once you are happy with the rigging, make sure your wingtip is not a problem. If you fitted the wingtip before rigging the ailerons you might have a problem.

TOM:
I WAS GOING NUTS TRYING TO FIGURE OUT HOW TO SOLVE A "HEAVY LEFT WING"
ON MY RV-7A. A WISE OLD BUILDER (2X RV-6s and 1X RV-7) GAVE ME SOME
GREAT ADVICE. HERE IT IS: GO TO averytools.com. ORDER YOURSELF A
"RUDDER TRIM TAB," ORDER NUMBER SKU: 9883, COST
$13.50. BOND IT WITH PROSEAL TO THE OUTSIDE, BOTTOM TRAILING EDGE OF
THE RIGHT AILERON AND LET THE PROSEAL CURE FOR A COUPLE OF DAYS. IT
WILL FORCE THE AILERON UP EVER SO SLIGHTLY - YOU WON'T EVEN NOTICE THE
UP AILERON WHEN YOU LOOK AT IT AND THE TAB IS SMALL AND INCONSPICUOUS
HIDDEN AWAY UNDER THE AILERON - PRESTO - LIKE MAGIC - I HAVEN'T HAD A
PROBLEM SINCE AND HAVEN'T HAD TO TOUCH THE AIRLERON TRIM BUTTON.
TRY IT - YOU'LL LOVE IT.

Dan has the idea, but instead of buying anything, it is easy enough to do with a small piece of scrap aluminum. Also, a myiad of less expensive bonding agents (such as JB weld) will work in place of the pro-seal (which has very limited pot and shelf lives).
