There are lots of good "educational" rocket kits. I have seen various groups use ones like the wee Estes UP Spaceloft. For a group I worked with, I selected the BMS School Rocket, having already built one just to see how it would go. I wanted a bit of a traditional kit with balsa and individual fins (instead of a premade fin can) to give a little more "craftsmanship" so to speak. Yet the kit is straightforward and easy. It also has a sharp look, and makes a model rocket of a worthy size. The instructions are excellent, though most kids only give it a glance and go. The pre-slotted tube makes attached fins easier and ensure better alignment for a beginner.
We built nine kits with no problems. Eight of the kids attended the local Tripoli launch and flew them with almost no problems. One hit a car under streamer descent, smashing a fin - that's just poor luck. One singed its streamer but there was no damage otherwise and 30" of caution tape later we were back in business. On almost twenty flights, that's relatively trouble free. (I did try to stress proper use of wadding and proper fit of the nose cone!)
All did their first flight on A8-3's and I was quite surprised at the good performance on such a modest impulse. The flights were low, to be sure, but higher than I expected. They actually could have used just a bit more delay - I think the ejection charge time was closer to two seconds rather than three. The beauty of the A8-3 is you can easily view the entire flight process. Most used a B6-4 for their second flight and were suitably impressed. One chose to use a C6-5 and I lost track of the rascal on the way up. Other than a longer walk, no problems.
The rocket's weight for its size is quite light, and I'm sure allowed the good performance on the A8-3.
