Estes Teros #1285 Upscale Background

The Estes TEROS started as a Coldpower Convertible rocket in 1972 - 1973.
The Coldpower Convertible line used a smaller Vashon style engine that fit into a BT-50 tube.
The ejection was an interesting spring release.

The other models to use the "Ram-Jet"  BNC-50BC nose cone were: #0816 Wolverine and the #1311 Laser Torpedo

Coming up:
I'll be making an upscale of the Teros using the Dollar Tree store champagne flute nose cone with the Quest 50mm tubing.
The outside diameter of the the original BT-50 tubing is .976, the 50mm tubing is 1.97".
This will end up being slightly larger than a 2X upscale.
