I take it they have the OOP motor program running at NARAM? I was hoping they would do that.

Sounds good. I also found a couple of Estes 1/2A6-4's with the date 5-4-73 Maybe I'll use them instead
Do you or anybody know if Estes used codes for the dates later on? I have some others here but no dates just something like 4P2 and 21P16.
Hopefully I will find out more info on those AVI motors (I'm working on it).

I launched my Golden Scout #1050 twice yesterday. I used a 13mm 1/2A3-2T and it seemed appropriate that I used an 18mm Semroc Engine spacer tube as the motor adapter. Both flights went very well with nice tumble recoveries. The characteristic ding in the engine from hitting the engine catch hook on ejection was present both times. The motor stayed in for both flights on ejection. I did notice after the second flight that the fin to body joint had a hairline fracture at the leading edge on one fin, I assume from the landing, but I'm retiring it, so no matter. Typical residue at the 3 ports. Great little flier. This was a great way to celebrate the 50th anniversary of Vern and Glenda Estes' contributions to model rocketry.

I launched my Golden Scout (Flight #1096) four times today. I used 1/4A3-3T motors wedged inside used 18mm motor casings.

Instead of using a shim, I used a stiffer wire for the "motor retaining wire." By bending the wire inward after installing the motor, the wire keeps the motor from bouncing back into the rocket (most of the time).

The rocket tunbled correctly three times and came in nose-first once.

I've created a high-speed (slow-motion) video of Flight #1096. You can see it at:

You can either view the lower-resolution YouTube version or click the link at the bottom of the page to view a high-resolution version using your media player. (Or "right-click" the link and save the video to your computer.)

I flew my Golden Scout (flight number 0379) yesterday and was unable to enter the flight information on the Semroc website. Anybody else having the same problem?
