RE: Craft Air Cowboy Build
No pic's, in fact the biggest reason I'm trying to share my build is because there is so little info on the model. I was given the plans by a friend who thought it would make a great "next step" in the progression plane. I've been offered a .25 engine for it but it's such a simple build I'm tempted to lighten the fuse and go electric instead. I've finished the tail group now too. For the tail group I simply followed the layout on the plan, nothing too fancy, just put down & cut to the diagrams. The LE's on the stabilizer & fin needed to be rounded so I made a block sanding "router" using a 3/8" cove bit and a couple of peices of 80 grit emery cloth. For the very front piece of the fin I used a round rasp that matched the profile that I had sanded into the main part of the fin. I also cheated a bit and used my disc/belt sander & mitre to get the angles right for most parts of the tail group. Other than the lead in part, the angle of the LE of the fin is 30*, the TE of the fin & LE of the rudder are 23* and the TE of the rudder is 15*. I'm still not completely done the wing yet, I'm not quite sure how I'm going to join the 2 wing halves together yet. I'm also considering making the tip blocks out of beaded foam & a light coat of epoxy for strength in an attempt to save a bit of weight.
