Guy's thanks for the replies, I'm really enjoying this repair as I've not done any proper modelling for around 18 month's (well I have designed a couple of foamies and put them together but that's not real modelling is it

) pretty much since I finished my ZN Twister, in fact I STILL have another Twister kit sitting in it's box ready to put together, maybe a build thread?............................
I've pulled off the project for the evening and will resume first thing in the morning after taking the wife to work at 6am, I really like getting in the shop early and getting down to it, I'm also really down with a tough cold/flu thing at the moment and the evenings seem to be the worst time for getting all bunged up again (why is that?). So tommorow it is, finish the final filling and sanding, then get the covering on, no big deal with that!
Dave, just to answer your couple of points, yeah the filler is just the type you mention, it's marketed as "Red Devil" over here as well as other names but it's the same stuff you mention, almost as light as microballoons. It sands real easy and I always give it a shot of thinned pva after just to seal the dusty surface ready for covering, I apply this using a small piece of tight cell foam, the kind you'd find in your TX carry case, used as a squeegy almost. I'll post up some pics of that when I get to it tommorow. I then use my covering heat gun to quick dry the pva coating being careful to keep the heat far enough away from the surface of the wing so not to cause the pva from bubbling up but close enough to rapid dry and prevent any swelling, hope that makes sense

. Your right on the money with the CA/Kicker method of application, however, I run a piece of masking tape along the inner most edge (parrallel to the span) of the piece of balsa that I inserted in the wing skin as a hinge tape kind of affair, then run the CA over the foam surface and shot the kicker on to the balsa skin inner, the skin is then layed down immediatley in to place and within seconds it's bonded and good to go!
Ryan,
That would have been so cool [8D], it's amazing how us modellers all think the same way when our fellow fliers need some support, great jesture there my friend, great jesture!
Regards,
Andy.
