I pulled out Peter Alway's "Art of Scale Model Rocketry" the other day, and that Astrobee 500 caught my eye yet again. So I decided to give a whack at it. This one's upscaled a little bit from the plans in his book. It's built with BT-60, BT-70 and BT-20. The nose cone is the Estes plastic cone supplied with their "Yankee" kit (it's available in their BT-20 nose cone assortment pack too).
The booster has a 24mm MMT, the sustainer an 18mm MMT. The BT-20 'Asp' section tube passes through the upper shroud section to the bottom of the JT-60 coupler which serves as the shoulder, so theoretically I *could* still turn this into a 3-stage bird, just like the original Astrobee. I'm thinkin' about it...
