Summary

This is a replacement fin can for the Estes Eliminator rocket, and will probably work for other purposes. It fits on an existing BT-56, and with sanding or fiddling, on a BT-55. It should be stable for all mid-power 29mm motors.

The picture with the fins attached to the unfinished rocket must viewed with "large view" to be viewed seen. Otherwise it's just a purple tube.

PLA in particular could deform when hot.  Sanding out the interior a bit and coating with epoxy could prevent this.  My final versions will be printed in ABS.  Future enhancements will allow for better performance at trans-sonic velocities.</p></div>
