I used a pack of 1/2A3-0Ts flying my Beta (Estes 0845) kit back in the mid-90s. They worked well, especially on small fields. I wish Estes still made them.

I remember picking some E18 and F24 reloads back in 1994 that were packaged in single packs. Those loads were changed to 3 packs sometime about 1996-1998 when Aerotech started stamping the manufacturing date on the instructions.

I can probably count on one hand the number hybrid motors that I have seen launched since 2010. In 2005, probably about 40%+ of the HPR flights that I have seen were hybrids. I think that the complexity of the hybrid GSE and extra requirements (electronic ejection) to fly hybrids have seen...

Aerotech actually produced and sold B6, C4, C6, C12, and E27-4 reloads for the Aerotech RMS-18/20 case back in the early 1990s. They discontinued a few years later the mid 90s due to low sales.

If the tube is a little larger than a BT-20, it is probably a a Quest T-20 tube. The ID of the T-20 is 19mm. The nose cone looks like a MPC/early Quest version of the PNC-20.

Aerotech does discontinue stuff form time to time. I have not been able to buy B6, C4, C6, C12, and E27 18mm reloads for more than a decade. I also can't F14s for about the same amount of time. Further, G33 29/40-120 reloads have been not been made since the 2001 Aerotech fire. I would like...

They switched to a full length BT-55 when Estes made the change to the PNC-50Y for the nose cone. The ARCAS (K-26/1226) was probably switched at around the same time. Estes was probably trying to save some money by not having to carry the BT-55V.

Personally, I would keep AP motors in a airtight container with some silica gel packets, if I was storing them for several (10+) years. Otherwise, I prefer to keep my AP motor stock low so they don't get very old before use.

Personally, I think the most impressive sparky motors were the Silver Streak motors from Rocketflite. Very low smoke and lots of sparks.

Your motor was born on 4/27/1994. My experience with motors this old is that the delay will run long. About 6-7 seconds instead of 4 in this case. Unlike White Lightning, Blur Thunder ages pretty well and does not swell up as much as WL, especially in the humid Southeast. I would recommend...

The Jolly Logic Chute Release works fine with the stock parachute. I would set it to release at 120m or 150m. The small parachute size is designed to minimize drift. The Aerotech kits in general are pretty rugged.

The Mini-Commanche-3 uses the PNC-20A, the same nose cone used in the Viking, Wizard and many other Estes BT-20 based kits.

BT-56 is the Estes name for the old Centuri ST-13 tube. eRockets still sells them as ST-13s. There were a number of classic Centuri kits that used that size of body tube. The first use of BT-56/ST-13 in an Estes was the Astrocam 110 (1327) to keep people from using other rockets to loft the...

BT-50. The nose cones on the pods are BNC-50Js.

Your battery should put out at least 12 volts. Most composite igniters require 12v launch systems. A pair of six-cell RC car battery packs will do the job.

Just put a nose block in the middle tube joint. It is much easier to transport the Mean Machine in two 3' sections than a single 6' length.

The Chinese made Quest C6 are more like C4 motors. They tend to work better with light, low-drag rockets than heavy, draggy rockets. An Alpha would be a great choice for the Quest motor, but a Fat Boy would not be.

As long as the BP is kept dry, it should work just fine. It is the AP-based parts of the motor that are really affected more by aging.
