When I was building I wondered about that - in fact like you I still do. I filled the tube up with anti corrosive paint to ensure complete coating (pouring out the excess). Every time I have the wings off I squirt with LPS. But even so there is the U bend where water can accumulate.

I would think that is a good idea - I will probably try to work out how to do that myself. In any case i think it is highly unlikely for water to get in while the plane is complete. however if youre trailering it might be a different story Thank said I have not heard of any cases and the UK is not exactly arid...

Most of the corrosion in the flap drive tube is from condensation. With gr ease on the flap pins and the tight fit of the bearings, no water from rain or tie down should get into the tube. If in a cold, wet, place, with no c orrosion control on the inside of the flap tube, a fine rust scale will nor mally form on the chrome moly as in any stick and tube aircraft. My tubes were filled with linseed oil as a film like the old timers did. O K so far, no serious corrosion but I do think a simple drain hole in the be nd is a good idea. If you have no treatment, Corrosion X or ACP50 in a =BC inch tube played in to the cross tube through the bearing hole and sprayed around with a bit of air pressure to coat the inside should work with the tube in place. Then for the purist, hook a vacuum source and pull out any excess fluid and it s hould soldier on for many years. Most scrap plastic brake line tubing is f lexible enough to do the job and even go down into the bend from each side. I never tried it, but I think I=92ll give it a go on 96EG (one of the early Classics) to see how it works. Bud Yerly Custom Flight Creations, Inc.
