Construction

Fliskit instructions are generally well written and clearly illustrated, and on a mildly complex kit like this they can simplify the build process a good bit. I deviated from the plan just a bit, mainly to allow for a paint scheme that could be all spray, no hand brushing. There were a couple of errors in the design encountered along the way, though I would imagine corrections will soon follow.

Construction begins by working the body tubes. The aft BT-20 serves as the motor tube, so just gets an 18/13 centering ring as a motor block. In order to keep the kit packaging (and shipping box) small, this design uses 2 12" tubes joined with a coupler rather than a single 24" tube, so there's a small seam to eventually fill/sand. Note that the coupler is also the shock cord attachment point, resulting in a small bulge.

A wraparound fin guide covers marking the aft tube for fins and details. There are two main fins and two small basswood stick time pieces positioned 90 degrees apart. At this point, things start to get a bit complicated. First, you cut two trim sections from the BT-70. These are designed to form arcs over the basswood trim pieces and span from fin to fin. In my case, the patters were significantly oversized, longer at the tips than the corresponding section of the fin that they rest against, so I had to trim mine down about 1/8" to fit. Next, the forward and aft gaps between these BT-70 covers and the inner BT-20 tube need to be covered, and this is done by cutting a couple filler pieces from 1/32" balsa. Even though the pattern is oversized and designed to be trimmed to fit, mine were too short, so I had to recut another set about 1/4" longer than the template called for. 

With the BT70 covers and balsa plates in place, construction moves to the intake assembly, a sort of ramjet style section comprised of a fiber base plate, 7 fins, and a balsa tap cover. Since I intended to use contrasting paint colors, I paused at this point to get some base painting done. I painted the fiber base plate offline a gloss black, attached it to the model, then masked it off. Next, I tacked on the two vertical stabilizer fins that but up against this plate and a rudder that sets on the opposite side with a launch lug. I took care of spirals, grain and seams, then hit the rest of the model with a gray primer, then a couple coats of white. Next, I painted the fiber radiator fins offline a gloss red, tacked them onto the (unmasked) base plate. I then cut the balsa top plate, painted it gloss white, and tacked it into place above the radiator fins. Good luck with that scheme trying to paint it after everything's built...
