I would use a 24mm Aerotech E30.

Stick with the single D12-3 (if that's how it is built) for the demo launch at summer camp. It will look good, lift off slower (more scale like) and the kids can see the ejection better. If it's built as a cluster, you don't have much choice, either 3 C6's or 3 B6's. Make sure you use a good 12v ignition source and check your igniters before installing them.


Hi, many thanks for the feedback.
On the older Centuri kit, do I need the clear stabilizing fins?
Havenít flown this in 20 years. Next week is the day
Thanks

I never flew mine without them. You might get by without them on a single D12-3, but I'd definitely use them with a cluster. Since the Centuri kit is such a classic, it isn't worth taking the chance without them, IMHO.

One thing I always did was to make sure I put the clear fin slot on the same side for all four fins. That gave it a slight roll, adding stability. If you don't pay attention, you could end up putting the fins on in a way that makes it tip over.
