…is the month for big rockets! I am building a fiberglass rocket that I plan to take to over 1000 mph. It has to withstand 35g and the Mach transition that tends to burn the paint and rip the fins off. I also have to get the on-board avionic computer and digital altimeter working to blow the drogue and main chutes at the proper moments. And that, it turns out, is the smallest rocket allowed at BALLS. Everyone else will be flying the big stuff (cruise missile boosters and home-made liquid fuel engines).
We have some other goodies planned for XPRS and BALLS at the end of September…. It’s all very exciting….
