Estes Sandpiper, Kit # 1389, Part 1, Parts






The Estes Sandpiper kit was produced from 1983 - 1984.
Vashon (Freon, "cold power") previously produced a Sandpiper about the same size. The Vashon version was hardly scale, there was no tapering tail cone.

With the release of the new, large Estes Jayhawk, I thought it would be interesting to build this variant.







This is almost a spare parts build, the 3D printed nose cone was explained in the previous post.
I redrew the decals, fin patterns and shroud. The shroud (as it is right now) may not fit the BT-20 and BT-50 tubes. I'll make adjustments before the PDF is available to Patreon subscribers. 

The original instructions and parts list: CLICK HERE 
The BT-50 tube is 7 3/4" long, the engine mount tube is 3 1/2" long.
The tail cone length is approximately 1 11/16" tall. The nose cone is 4 3/8" tall, exposed.
That long launch lug is an LL-2E at 9 1/2" long. 12" long launch lugs can be ordered from jonrocket.com and cut to size.
Clay weight square (not shown) is 1/2 oz.

The payloadbay.com website is down right now, 
I had to find another shroud generator, this one is from:

Before I had the 3D nosecone, I had ordered a SEM-BNC-50YP balsa nose cone from Erockets.biz. 

If I couldn't get a plastic PNC-50S, I was going to add the upper vanes like in the old Vashon kit. The vane template is directly below the balsa cone.
