"This is a replacement fin can for the following model rockets:

Enerjet 1340
Enerjet 1340/20
Centuri Phoenix Bird
Centuri Argus
Centuri MARS Project
Estes Longshot
Estes Maniac
Estes Challenger II
Estes Eliminator
Estes Eliminator XL

The dimensions were taken right from fin can and put into the CAD program I used to design it. The tubing designed to use it is Centuri ST-13 and the Estes BT-56. You can always scale it up or down to fit.

Will it reach and pass through transonic speeds and even into supersonic speeds remains to be seen. The massed produced one that came with various kits was not able to do so."
