Looking over the Micro Scale building que I noticed a model I've had on the list for several years.
The Aerojet General Astrobee-500 3-staged sounding rocket. My intent was to try to 3-stage it. Well after several recent looks at doing so the best I could do would have been 2 staged but I decided to built this model as a single stage sport Scale instead. If it flys fairly well I may try building another staged.
The model really has some off sizes requiring the use of T2+ Minimum diameter MMX body tubing Only for the Motor mount with 14mm and 19mm main body diameters and a long T2 (.246") third stage probe.
To save as much mass as possible all transitions and centering rings are 110lb Cardstock. the Rings are laminated 3 ply cardstock.
Fins are on piece .032" Basswood.
Shock-line and Anchor are a combination of 49strand Stainless steel Beading Wire with 30" x 70lb Kevlar.
This model will use a 1/2" x 12" Yellow PTFE Streamer Wadding.
