Estes Saros / Nomad Upscale (BT-55)

thingiverse

I've always liked the Estes Saros rocket for it's sleek scale like appearance. The original kit was available from 1971 - 1978 and it is hard to come by these days. The kit came with a plastic fin unit, plastic adapter/transition and a plastic nose cone. You can download the Saros instructions here: Saros: http://plans.rocketshoppe.com/estes/estK-54/estK-54.htm You will need the following: - 1 x BT-55 268mm (10.56") long - 1 x BT-50 225mm (8.86") long - 1 x BT-20 178mm (7.00") long - 2 x Launch lugs 15.8mm (0.62") long - 1 x Engine hook - 1 x 381mm (15") Parachute - 1 x Shock cord - and 1 Saros decal sheet which you will have to print out. The scale of this version is factor 1.363 compared to the original size. Assembly Notes: - I've added pictures to aid in construction. - Use the positioning tool for engine block placement and for engine hook slot position. - I don't really recommend gluing the nose cone and the adapter to the BT-20 body tube. This would make replacing any damaged parts easier. Friction fit is sufficient to hold everything in place. - The same goes for the fin unit to the BT-55 body tube. - It is also not necessary to glue the engine hook retainer in place. This way you can remove the engine hook for a nicer static display model. However it is possible the due to heat from the motor that the retainer will shrink making it hard to remove again. - Paint the body tubes in white. One fin is painted in black. The fin mounting plates are painted in silver. - I use 5 min Epoxy for the complete build. This rocket flies great on B6-4 and C6-5 rocket engines. I would love to see your results!
