Hi, I'm currently drawing plans for a Cessna 140 that I want to model. The wingspan will be 56", and I hope to power it with a .26 or .30 4-stroke. I also want to put a scale interior in it. I am having difficulty figuring out how to attach the wing. Most of the kits I've built have had the wing spars continuing through the fuselage, and have bolted on in the rear. On this particular model, this would get in the way of the scale interior. Also if I put in a scale interior, how would I access the radio gear like the battery and receiver?
