Default NARAM-52 and the NAR Expired Motor Test Program

I flew a fair number of rockets at NARAM-52.

One thing I had planned was to fly several out of production motors under the NAR Expired Motor Test Program.

I have several Cox D8-0 motors in my collection so I thought I would use one as a booster to a current motor in a two-stage rocket.

The Estes Mongoose was my rocket of choice with an Estes B6-6 motor in the upper stage. Ignition was by Quest Q2G2 ignitor.

The D8-0 motor ignited promptly and propelled the Mongoose off the pad. When the D8 had finished it's burn, it ignited the upper stage B6-6 motor. The flight was completely successful and both stages were recovered (It did take awhile to find the first stage).

The performance of the Cox D8-0 was impressive, it really pushed the model into the sky. It would be neat to see the return of this motor (hint, hint ).

Pretty cool! I love those old, vintage motors. How did the first stage look when recovered? On every Mongoose I've seen flown, the first stage is always very stable (instead of tumbling) and acts like a lawn dart to the ground, damaging the upper tube.

I did not see how the first stage acted after seperation. It appeared to have dived straight into the ground and landed in some soft mud. After I cleaned the mud off, the booster looked fine.

Hmm... That gives me some warm fuzzies as I consider burning one of the five D8-0's that I have.
