I would like to know where I could purchase wedges? I am planning to use one on my aileron and wondering where would be the best location to place it and what to use to attach it?

Avery has wedges, I think. You can make your own out of wood for a trial. Place it near the inboard end. Start with double sided tape so you can remove/adjust/lengthen/shorten.

Can anyone tell me why a tab is not preferable to a wedge? Easy to install and easy to adjust. I must be missing something. Doug Dahl

A trim tab on the wing tip will not cause flaperon flutter.

Thanks Joe, very helpful, does anyone have any pics of tabs on wing tips? How have they worked out for the users?

Lots of people use this wedge:

Most have needed it for the rudder, very few for the ailerons - the aileron "squeezing" seems to work without a tab or wedge.

Wedge

On my RV6 I used the balsa trailing edge for model airplanes and sold in hobby shops. Bought a piece, trimmed until right, painted like the airplane, held on with clear packaging tape. Has been there 12 years including some flying in rain. I am amazed at how well it is holding up.

RV12 - trying to work out exactly the right place to bend that firewall to bulkhead fuel return line.

RV6 - finished in 1999, still doing great

Avery wedge works great!

No need for aileron trim tab. Trailing edge squeezing works great. DO it A LITTLE BIT AT A TIME! Small squeezes make big differences. Avery wedge works great. I used one full tab on left side. Looks good and won't get bent accidentally like a trim tab. See here: http://www.mykitlog.com/users/display_log.php?user=BigJohn&project=639&category=0&log=123536&row=38

The trailing edge of the LIGHT wingtip can also be squeezed, very carefully.

John:

In my case, even significant squeezing of the light aileron (or flaperon) did not correct the heavy right wing. It only partially corrected the problem and we reached a point where additional squeezing was not possible due to the trailing edge of the ribs. I consulted with Vans and they suggested trying the trim wedge instead- that has solved my problem. I may be in the minority and am not sure why mine was so difficult to resolve. I am strongly considering an aileron trim system longer term so that it can be adjusted for any flight condition.
