I've assembled the fuse on my 4*60 and noticed some small gaps between some of the formers and the top/bottom of the fuse. The gaps look a little too big for CA...should I ignore them since the former sides are bonded or try to fill the gaps with epoxy? Also, I plan to sheet the back deck...should I just trim enough off of the deck runners to allow for sheeting them add some blocking at the top of the fuse for backing?

Iraqvet, I would block the gaps with some balsa. In my opinion, its impossible to make an airframe too strong unless you make it so heavy it will not fly. Remember that most RC models are seriously overpowered and that power to weight ratio can put tremendous strain on the airframe.

use some sawdust from sanded down balsa and thick CA to fill your gap. unless its to big(are you talking 1/32" 1/8" or what) As packet said when you start using epoxy everywhere you are adding unnessesary weight. Light spackel or wood filler will work also.
