Kopter Bat
 

http://www.ninfinger.org/rockets/ca...er/kopter8.html
Looking for something interesting to build this summer and the Bat caught my eye. I'm having an issue figuring out the dimensions. Not sure if it's just old eyes or a blurry scan.
Just checked, and Chas provided the scan. Any chance you can check the catalog for me, Chas?

Hi Bill... found a PDF of the catalog with clear information on the subject...

I tried to resize the picture of the rocket to the 20.25" length the specs say and it did not scale up well... the body tube on the picture is wider than what the specs say, it comes up to a BT-55.

Hope this helps a little.

Bill,

I found that I have two Kopter catalogs that appeared to be identical. No catalog numbers or dates. Only changes are to the price list and that one catalog has the Bat and the other the Astros plus the first also has the Mini-saur vs the Delta Streak in the other.
The catalog with the Bat and Mini-saur appears to be a later catalog as the prices are higher... :D

The Bat is listed at 20.25" long and 0.71" diameter. Recommended motors are A83, B4-2, and C6-3

Hope this helps.
