A few years ago a club member launched something like an upscale Tornado and I loved it. Unfortunately, I didn't get his name or any details of his rocket. Recently, I realized that it was based on the low-powered (LPR) Estes tornado. I found the Tornado RocSim model on Rocket Reviews and downloaded it and proceeded to upscale it by a scale factor of 3.48. I then proceeded to replace the parts in the RocSim model. I wanted to use parts from my inventory, so actually the model is not a true upscale. So, originally the airframe was a BT-20 and now it is a BT-80. However, the basic idea to use "maple seed" recovery for the upper part and flutter recovery for the lower part is preserved.
I plan to use 24 mm motors, so the fins will require through-the-wall tabs. The exterior shape of all 3 fins is the same (although different from the original Estes), but the tab will be different for the fin that goes in the maple seed upper section.
