Can this be done on the Europa? I've seen an article (from a fellow forumite) that involves building up the thickness of the surfaces and sanding to reprofile, but I don't really fancy this route if I'm honest. Had anybody done anything (ideally UK approvable) on their machine?

Invisible from above, sticks to the aileron by itself, can be cut until you are happy, and easily modified/removed. Worked well all flying season 135 hours .

Good quality rubber. I used it also in lieu of the tail plane strips. They worked fine. However, am considering replacing them with balsa strips as per manual.

Rather than glue on tabs to flying surfaces, I went the internal elastic bias route. At the bottom of the pilot's stick there is a bolt which secures it into the socket. The thread from the bolt pokes through the nut to the rear of the socket with several thread turns to spare, so it's a simple matter to turn another nut "backwards" onto the thread until it butts against the first nut. This pair of nuts now provides a concave groove between them. On the left sidewall of the fuselage, nearest to the pair of nuts and in line with the left-right deflection of the stick, I cut a small "X" in the carpet to expose a 1" square of fibre-glass which I cleaned and then bonded on a plastic anchor of the type used to support bundles of electric wires. All that remains is to attach two or three elastics of the type which our post lady uses to hold bundles of letters together and "Voila" you can stretch as many of them across to the pair of nuts as you wish, to eliminate any strong right roll tendency. Of course they aren't strong enough to present any kind of hazard to flying control.

Helpfully, that had a screw adjuster on a lift strut so that you could adjust the incidence on one wing. I'll have a go with the foam strip at the weekend, and see how I get on.

When flying by myself it flies wings level. Like others, I have added a strip off foam. The stuff i used is as per the link below to eBay. http://m.ebay.co.uk/itm/150900600898?nav=SEARCH Hope this helps.

I used a pencil split along length. And glued under trailing edge of the appropriate aileron. Then 'hands-off' !!!
