RE: Bob Cat Copy Falcon 120 Jet
Hi Sara,
For some reason my friends decided to watch instead of take pictures... Go figure. I'll have another go next Friday. Hopefully we'll get better pictures then.
Jeff,
The tube is only used for startup. The stab is rather delicate and any flames during startup torch it immediately. It's simply a rolled up strip of aluminum that has legs attached with a clamp. These legs are pushed into the sand and hold the tube in the air.
BTW,
I've since come to the conclusion that the spin was due to the float reducing spiral stability. I'll be adding subfins underneath the existing fins to improve this.
