I've been building a CGB superchipmunk for a few weeks now. Fuse is almost done, tail is done, wing is, well, done. Done in a bad way as far as the wing goes. Landing gear blocks have been beefed up, but I screwed up, and a lot of the glass I put in to re-enforce hasn't fully adheared to the wooden structure. The sheeting is crappy, and the servo mounts are wrong (I glued in the ones for the bellcranks, then switched ideas..

I hate built up wings. A lot of work, but fragile, and if you're not a wood craftsman, but you are a perfectionist, VERY aggrivating.

Here's my question. I'm going to have a set of foam cores cut, and I'm going to vac bag them with glass/epoxy. What, as far as a spar, will I need? Also, any articles on mounting retracts (I'm going retracts now) in the foam wing? I'm concerned with damaging the wing on a landing due to bad retract mounting, and considering I've never installed them before, I'm sure I could use the help.

Thanks!!!
