Estes Puma #7256 Build, Part 1, Parts







This is a detailed BT-20 based mini engine model. It looks to be designed to go alongside the earlier released Lynx and Scorpion models. I picked this up on clearance at Hobby Lobby.

You don't find many kits with 1/16" thick balsa anymore. The balsa is thin to construct the wing engine boxes.
The parts of interest:
That bulbous canopy nose cone
Two small 3/8" long launch lugs
The multi-pieced laser cut balsa
The dowel was curved, a bit of a warp




The engine vanes are very small. One had come off the laser cut sheet and was at the bottom of the bag. It'd be easy to lose, I put it into a small zip lock bag.

  1. BT-20 based rockets are ac real pain to prep. Those 6 inch parachutes would drive the most patient person crazy. Danielle has a Scorpion, and it amidst never gets flown for this reason.

    1. Hi Metal,
      When I started in 1969, many of the rockets I had were BT-20 based. The Sky Hook, X-Ray, Wac Corporal and Apogee all had 12" chutes!
