Default Upscale of Estes 1380 AIM 54 Phoenix

I added the Estes BT 80 rocsim file, remeasured the kits fins and corrected the online version with this one.

This is a 3" upscale of the Estes kit using BMS thin walled 3" tubing. I did round of a little on the fin measurements on this upscale for ease of cutting, but they are very close to the Estes original. A coarse this is a semi scale at best. You can compare them to the Estes file I corrected and added to this post.

The nose cone for the 3" upscale would be closer to the Estes & original rocket if you use the Estes 3" x 9" long nose cone. I went with the BMS 3" x 11" cone, looks better, a little more stable in flight and this is a semi scale at best.

I also changed the motor tube location and added two more center rings for strength with plastic 29mm motor retainer. Don't like the base to get dented up on landings.

I'm going to try balsa forward fins on mine to keep weight down. This is a small local field flying model.

Don't forget to add nose weight for the different motors you will be using.

Hope this proves to be of some fun and help to some of my fellow rocketeers.
