Challenger 1 Upscale
I noticed that my fleet is short on D powered birds so I've decided to add an upscale of my Challenger 1. Decades of use have taken their toll on my first rocket. Although still a great flier, it's becoming so brittle that I'm going to have to retire it to desk duty on the workbench.
The new one will be based on a BT-60. It will use an 18" tube and a Semroc 60YP nosecone. My math shows that the tube is only about 3/8" too long and the nose 1/4" longer than exact scale, so I will leave them as they are. I made a pattern and cut the fins from 1/8" basswood. They will be sanded to a diamond airfoil as per original. I have some plywood rings but will need to make a motor hook. I am also considering installing a baffle. I'll have to locate some decals and scale them up as well. |
