You built your Enerjet Aerodart the same way I incorrectly built my first one.
The Enerjet version only has 3 fins, not four like the earlier Centuri version.

It sure looked like 4 in the photos.
Lucky for me I have 2 more of those nose cones. |

Enerjet Dart
Another use for the 1340 booster - This is from the Sept. 72 Enerjet News.
Shouldn't be too difficult to throw together.

I wish that the folks at Estes would clue into this and bring some of these kits back. At first I was thrilled to see the Estes Phoenix Bird... But the complexity of the balsa fins defeated the simplicity of the original Centuri kit. Don't get me wrong, I like balsa fins, and can easily build those kits, but the design was IMHO originally a beginner's kind of rocket. The exciting design and simple build practically guaranteed that noobs could make a cool rocket, gain confidence, and want to stick with the hobby. The fact that guy's like us are still excited about them should reassure them that the kits have staying power.

And the REALLY silly thing about the Estes bring back of that particular kit is they had the fin can mold from the original kit and were activily using it in kits like the Eliminator. And so they bring back this classic kit -- one of the first kits to ever use the this plastic fin can -- and what do they do? The issue the kit with BALSA fins!! (??). Balsa cheaper? Yes I'm sure. But if you are going to bring back a classic kit and can do it faithfully and you ALREADY have the fin can, why not use it? So yeah, could have been a good bring back in a lot of ways, but they missed it big time on that point. Earl

Part of the problem is that Estes is phasing (or has phased) out the BT-56. The logic is that the BT-55 is so close to it that it won't be missed. Personally I think that's a little shortsighted. There is a lot of history behind that sized tube and I think it should never be eliminated. Likewise the egg capsule for the BT-56 is gone. It's my understanding that the mold for it is close to being worn out, or has worn out completely. Which is a shame because I rather like that funny little nose cone. However, I do prefer it in the HIPS plastic instead of the Polyethylene plastic, due in full to the ability for paint to stick to it.

I saw that fly at the Southwest Model Rocket Conference in New Mexico in 1973...Gary Schwede was a very clever individual--that model had a modified Estes Transroc with a nose tip thermistor probe. The upper stage ignited via a timer that started when the umbilical plug pulled out at launch--hearing the upper stage EnerJet motor light up was awesome! I also *did* see Larry Brown from Centuri fly the X-24 bug on top of a Saturn V at one of the SWMRC, unfortunately, I did not take pictures that year... |

Gary's original EnerJet dart model did not use the plastic fin can...this is from SWMRC 72. Looks like this was the inspiration for the model in EnerJet news drawing
