I built six of those back in the days of the original kit. One for my own fleet and the other 5 side by side for Estes' "Build-Up" program. For those of you who don't know what that was.... back in the mid-seventies, Estes Industries would invite rocket club / NAR section members to participate in building up kits that they would take around for display at trade shows and other events. The only stipulation is that the models had to be built to "Catalog Quality", meaning flawless finishes. It was all about appearance. I seem to recall that a small number of some models wanted for this usage didn't have to be built with all flight components in place (engine mounts, shock cords, etc.) because they were earmarked for static display only. The SWTs were full builds, however. I remember a lot of hours filling and sanding fins and body tubes. Back then, we didn't have CWF, so things were done with Aerogloss Balsa Filler or Sanding Sealer. I seem to remember the club I belonged to getting somewhere around $10 - $25 in Estes merchandise certificates per bird, depending on complexity of build. It was a great way to stock up on kits for the club to use to fly at public demos and for competition meet prizes.
I have a Scissorwing Transport clone on my near-future BAR - build project list. Looking forward to that one!
