That's funny. I can see how a D21 might tear the fins off of an Alpha. But I will have to try a D10 some time (when I'm at a much larger than usual field).

We just got home from doing the launch for the Alphas we built at the Museum of Flight yesterday. Most of the 45 or so that were built yesterday turned up today. Lots of B6-4 flights.

All were recovered and we only had one separation - it looked like a poorly tied shock cord at the nose cone. Only a few flew as if they had significantly misaligned fins so the Qualman fin jigs that David Qualman supplied us (see the third picture in post 45 above) clearly helped make the models better.

A good time was had by all as we flew off of old launchers. We used a 1966 Electro-Launch, a Tilt-A-Pad, a BigFoot, and two Porta Pads (not Porta Pad IIs) with an FS-5 Launch Control System, a 2212 Astron Launch Control System and a Centuri Powr-Control on the tripod pads.

Fun stuff.
