I built mine with Titebond wood glue and 5 min epoxy on the motor mount, no internal fillets or other fancy stuff. Flew it at Hartsel CO (8,000 ft above Sea Level) on an I 260 Medium with the delay cut down a bit, the biggest, awesomest motor I have ever flown.
Nice whistle as it went up. Got a small zipper so I probably should have left the delay alone at that altitude. No other damage, the wood glue held up fine. All stock components from the Xmas sale package. It needs at least a "260" punch as it is a heavy little tank and needs to get moving off the rail. Secured the epoxy Copperhead BB mixed nose weight with a drywall screw. I filled in the gaps under the rear fin plywood mounts with tube bondo. Two heavy coats of primer sanded and multiple coats of white paint and the fins were smooth. Lots of electrical tape striping and black vinyl letters from Office Depot. Used well nuts to secure the rail buttons. A nice light sand and the paint stuck good to the nose cone, but it will still flake of if it gets a good bang.
