So you're covering the wing, horizontal stab, and vertical stab with Monokote? I've built 3 electric King Kobra's and have always tried to keep the airframe as light as possible because I power them with a 6-cell Lipo .... a big brick of a battery. So the vertical stab, rudder, and elevator are stick-built and I've lightened the fuse. Covered the whole thing with Ultracote. Wish I had painted the fuse but thought it was a bad idea given my attempts to lighten the plane.

Are you powering it with a glow motor? I'm very fond of the King Kobra - am building a scaled up version of it - has a 80" wingspan. Powered by Power 160 electric motor. It's a tail dragger to save weight and remove the added complexity of a nosewheel.

Would like to see pictures of your KK when you're done. Have fun!
