Geez, I see that this forum has had one post today already, we don't want to over do it [)].
....1/2Aers hard to set up?
You can almost completely bypass hobby store hardware. I've used 1/16" copper coated brazing rod for push rods and 1/16" ply control horns. Just use medium CA to glue them into slots in your flaps. Bend a V shaped bend into the wire for adjustment. I use Hayes brand 2 oz tanks and simply tie them to a profile style maple/balsa/1/32" ply sandwich engine mount. The Hayes tanks take longer to take out of the wrapper than they do to set up.
The HS-81s work well for elevons, I set them up with bulk servo wire to save the cost of servo extensions. That about wraps up "set-up".....well, the wing tip fins are double back taped to the wing tips after covering, uhhh....oh ya, don't forget to get your hands on a Cox rubber 5x3 or 6x3 prop, they are nearly unbreakable.

PPS, cover the planes with $2 per roll craft store cellophane that has been misted with 3M77 and use clear packing tape to reenforce seams and cut-outs. This stuff is much easier to use than hobby shop film.
