Get a pad with 3 legs, since 3 legs will always be stable:

I see your point. A 4 leg or similar style pad can be aimed by a single, simple 16 oz beer can (or in a pinch a rock). Oh, and have a far lower CG, and far wider rod and rail compatibility. Jerry |

I really liked Feyd's link to his launch pad build. That looks like the way to go! (That and an Aerotech controller.)

Also, I bought 4' launch rods from an on-line metals company and they are working out well. They came shipped in a sturdy tube and all were straight. Inexpensive rods but shipping was a little much (at least to me). Launch Rod Steel Which grade of steel/metal did you buy? How bad was the shipping? Thanks, Bob p.s. Nice fleet/build pile!
