Needed them in a hurry and Estes came through!!

I have been using these Alpha iii rockets for around 10 years in Vacation Bible School. This year there were several additional boys. I needed rockets fast!! The gentleman at Estes worked with me on the phone and the rockets were here the next day early in the morning. As far as the rockets themselves go. I have never had a problem with them. They are easy to build. And the boys like launching them off.

Awesome for groups

No idea what the 3-star review built, but the big selling point of this kit is that the fins come as a pre-made piece. This eliminates the need for kids to struggle with that part. Also tends not to break when kids don’t pack chutes properly.

I use this bulk pack for scouts aged 6-17. While the kit is a bit simple for the older kids, they enjoy helping out the younger. I use Aileen’s tacky glue as it dries in an hour and is easy to clean up before that. Less messy than white glue and less dangerous than super glues.

While the instructions are good, I prepare the parachute between the motor tube and fin can assemblies. This allows drying time. I also attach the parachute to a #12 snap swivel so that I can teach how to fold and pack while the motor tube dries.

Once the motor tube is in the fins and they are attached to the body tube, I set that aside to teach how the rocket motors work and what the letters and numbers mean. I finish up with the mounting of the shock cord and tying it to the nose cone. Clip on the chute and done. I recommend not packing until just before launch.

I recommend getting the clear Phantom if you intend to teach to groups. It’s the same rocket in clear plastic, so it is easy to show inside. It also comes with a cut-away motor to show the internal sections. I put bright orange tissue paper in as “wadding” so it shows well.

Once your group masters this, I recommend the Green Eggs bulk pack. It’s more $$, but kids really get into the challenge. The C11 bulk engines are fine for this. D’s are more dramatic, but much more $$. I typically only provide a D to those kids that successfully recover without damage on 2 C11 launches.

Oh, and buy small eggs- leaves more room for padding and improves success.

Thanks Estes!

The rocket is flawless in terms of ease of assembly. However, we and our 10 yr-old coworkers missed the balsa cutouts and gluing followed by painting. If they are still available, the catalog is unclear.
