Personally, I like to use polyurathane glue for most foam work. I use elmers "ultimate glue", Gorilla Glue is the same stuff, more or less.

Goop melts foam, so you can't use it directly on foam. I've used it to glue on the canopy, and that's about it, really. On the P-47, I might have used it to attach the vertical and horizontal stabs, I don't recall exactly.

When I first started, I was using the 270mah nicads. They are ok. But honestly, it seemed to me that the hitec packs aren't using the best quality cells. I had a couple go bad on me. You can get 300-350mah nimh packs from places like cheapbatterypacks.com or radicalrc for about the same cost, less weight, and more capacity. A 720-750mah Nimh pack weighs about the same as the 270mah nicad pack, and allows longer flying.

With the 270-350 size packs, you'll want a field charger. You'll get 2-4 combat rounds on a charge. I tend to recharge at least a little after each round to be safe. With a new nimh pack, you'll want to slow charge it a few times. After that, I can charge it at about C, or .3-.4amps.
