- These are good suggestions, and very timely.

- My problem with the antennas (antennae?) coming off was not aero forces
- but recovery snapback. There was the classic dent in the leading edge
- of the body tube and the toothpicks were ripped off *up*. I lost one one
- the first flight (a "B" powered checkout), one on the "C" powered second
- flight and two on the "D" powered third flight which CATO'd as it left the
- rod. The legendary Peggy Apple forwarded me another kit and pack of motors
- even though I couldn't find the casing of the one that blew. I am just about
- to start building it, so I'll try your suggestions (I like the idea of
- using "real" metal anttenae). My only reservationg is that if you make the
- attachement of the part that breaks off stronger, it'll do more damage when
- it finally does go!
