I am nearly finished building a Bridi Utter Chaos right now. Everything is pretty much ready to cover. Just take your time and be sure that you follow the steps. I used a jig for building the wing and I also cut lightening holes in the spars. The wingtips are solid balsa and I hollowed thos out. I set it up with 2 servos for the ailerons so that I could utilize flaperons. Let me know if I can help you. [8D]
