I am kind of new to this. Like 4 days old new, so if I am doing something stupid please understand it is not intentional and I could use a guiding hand. I have trouble following the "normal" path for any hobby as I find I learn much better trying to do my own designs. Today I took a pile of balsa, made some plywood, cut some fins and tried to hand sand an airfoil. Here are the results so far. I still need to fill and sand these so they are a bit furry.
The goal of the attached rocket is to go up and come down with an A engine and have it still in good enough shape to repeat with a B and eventually a C. I wanted to stay between 1 and 2 margins for all engines, and keep my fins simple enough that I could practice doing this airfoil thing without the complexities of a moving 1/4 chord line or radial taper. I do not know how to put an engine hook into Rocksim, so try to imagine one there In the actual build I will be using the 24/29 motor mount kit from apogee just to make sure I at least get that part right. Rocksim shows stable flight with deploys reasonably close to apogee for A8-3, B6-4 and C6-5 motors.
