Alien R-Candy Motor test with delay mechanical deploy
This is a motor test with my new Alien R-Candy formulation, the delay grain is flexi-fuel and the mechanical deployment with fish-line release is being tested. There were no leaks in the delay grain and the mechanical release worked as expected. YIPPEEE !!!!
The fuel has been around for 4 days. Was even frozen for a while...so it seems that it did not shrink away from the walls of the grain tubes and remained safely inhibited. The burn time was a tad faster than flexi-fuel.

My New "ALIEN" R-Candy
In my attempt to try to make a more "pourable" fuel I used 65/35 KNO3/SU and 10(milliliters) Antifreeze. The fuel was very pourable "workable" but to crumbly after it set up. It burned at 10 seconds per inch. So I reduced the Antifreeze to 7.5 percent (9 milliliters)and this seemed to still pour well and set up solid. The burn rate is about 7 seconds per linear inch very close to standard R-Candy. Interesting thing: would it be 6 seconds for 6 percent and 9 seconds for 9 percent? Just an observation.
The test strand here is a tad shorter than 1 inch so it only took about 6 seconds to burn. The fuel seemed to inhibit very well to the casting tubes. I think this will be a good fuel for casting. The Antifreeze gives it the GREEN florescent color thus my naming it "ALIEN" R-Candy.
I guess to say antifreeze by percent isn't really accurate because its not by weight but milliliters. Please TAKE NOTE of this discrepency in post.

Scratch Built Nose Cones Using Crown Method
Thanks to Serge for the idea. This was my first attempt at making my own nose cones using the Crown method and same tube as used for the airframes. They aren't "perfect" but now I can make nose cones for pretty much any size tubes.
The small cone is 1 1/4 inches in diameter. The cone on the right is 2 3/8 inches in diameter and is finished and painted below. Not a bad olgive attempt if I may say so myself.
