Although this isn't the most original plan around, I was able to get some interesting performance out of it.

I call it "Hyper Loader"...

G35EM-10......3490'......Dv 18 FPS......60" Tower
H165R-14......4290'......Dv 21 FPS......36" rod 3/16" dia

H220T-14......5300'......Dv 18 FPS......36" rod 3/16" dia

Length: 43.1"
Diameter: 2.34" (ST-225 payload, ST-125 main body)
Weight: 15.53 oz

Enjoy!

Very cool Craig! You used the big 10.3" "Fat-Ogive" cone from Semroc and the new BR-125-225

Not a Centuri Hustler and not an EnerJet 1340/20 either but definably EnerJet-Ish because of the fin can. I like this one! I'm surprised with the large cone and transition that the dry weight still comes in under a pound.

I've only used the RockSim subassembly feature once or twice and it's been a while. Can I add the molded plastic launch lug for that fin can into your subassembly or do I have to create an entire new subassembly?

Thanks, Steve...

You only need to add the launch lug component, specify the material as poly PS, and save the subassembly locally on your computer. Then you can call it up at any time, as RS saves it into a folder which you specify for subassemblies.

I knew it had a Centuri-ish look about it. Maybe that's why it popped into my mind so quickly...

I named this one as a sequel to the Estes Challenger II. It may be a little more useful with the payload section...

Borrows a few ideas from the EIRP Starship Excalibur to keep it from being bland and ho-hum...

Imagine those bulkheads as being 1.5" long BC-5 ogive nose cones, cut down and shaped to conform to the ST-13 tube. Also, those ST-5 tubes are cut down their lengths to be glued up against the ST-13 tube...

Length: 23.3"
Diameter: 1.34" (ST-13 / BT-56)
Weight: 3.47 oz

D12-7......1170'......Dv 14 FPS......36" rod 3/16" dia

Enjoy!

The GoonerJet 1340!

Why build that same tired, stale, albiet stylish and sophisticated, EnerJet clone, when you can "Get Goony" with this classic plastic fin unit? Go play "chop-chop" with that body tube and get started!

Length: 13.6"
Diameter: 1.34"
Weight: 2.62 oz (includes 0.5 oz ballast)

B6-4......265'......Dv 18 FPS......48" rod 3/16" dia
C6-5......740'......Dv 8 FPS.......36" rod 3/16" dia

Enjoy!

I take busted up Generic E2X rockets from the school launches and make two stagers out of them to use for demo flights the next year. I have always intended on painting them up and calling them Challenger III's to pay homage to my first purchased rocket, but I never do. Since we almost always lose the sustainer, I just leave the bodies painted as the kids had them when they were single stage rockets.

I'd post some pics from the last few years, but I don't have signed waivers from school. These days, I'd get fired and sued for every rocket penny I have just for posting a picture of a kid having fun on rocket day.

Now that's creative. Very cool Craig!

I saved your Challenger III 2-stage file as well. You have a 2.5" bulkhead thickness/length with about 1.5" exposed in the design file. Would a Semroc BC-514 or BC-517 work or is that what you had in mind? Those are 1.4 and 1.7" exposed length plus whatever the shoulders are.

I was going to add the molded launch lug into the fin can subassembly later tonight and I noticed you already did that ..... thanks! Now I can save that subassembly with my other design files. I hate having to move all those individual components around.

Shame on you .....

I guess the urge to "Get Goony" with the 1340 was just too much to resist

That's a good idea to recycle the E2X rockets into two stagers. I'll bet the pics are interesting.

I wonder if anyone has tried any of the new Quest T-Minus 5 RTF kits. Those are pretty inexpensive .....
