Any Series-5 ogive nose cone that doesn't extend up to the edge of the tube would be fine. I wasn't looking at the spec sheets when I added those in, and that shoulder is obviously too long for any of them. You could even use a longer one at the top and a shorter one at the bottom (or the reverse)...



Each time you use that subassembly, though, it will throw the lug out-of-sync with the shroud, because RS doesn't allow you to link the lug to the shroud. Dumb and illogical. You can only link it to an outside tube. Just be aware.

Dirty job, but someone had to do it first...

With a full 18" length of BT-50 on the sustainer, and a short 1.5" length at the top of the booster, you've built yourself a clone of the Estes Scorpion...

How well do your 2-stagers fly?

Yep. That's why I didn't fool with testing for stability. I just looked at the Scorpion dimensions and knew the rockets were long enough to be stable.

The crash bashes fly great. I use streamer recovery and I've still only gotten one back in the four or five years I've been using them. It doesn't cost me anything to lose them, and it takes minimal effort to slap one together. I've been useing the same booster stage every year. I use C6-0 to C6-7 and don't expect them back. I just want the kids to see some high altitude flying. Our playground is small, so my demo flights are heavy, fat, noisy rockets to keep them in the recovery area.

I noticed this. I thought I was doing something wrong

Subassembly is a great feature but if all of the subassembly components can't be linked to each other to form an "independent subassembly", it sort of defeats the purpose to have to copy and paste or move one of the components around. Just another RS quirk .....

Still better than moving ALL of the components in every design file

I know I've used a similar design before, but I think it was a smaller model. I cannot remember which one...

This one uses that nose cone from the Estes Cyclone and the Centuri Taurus and Space Shuttle.

Here's an improved drawing for the EnerJet fin can, with everything in-sync. I added a 3.75" length of ST-13 as a reference tube in the subassembly. The easiest way to use this is to simply lengthen the reference tube as needed. All of the components take their position from the base of this tube.

Enjoy!

A brilliant solution for simulating the EnerJet fin can Craig!

That's a much needed work around to simplifying building this part into the design files.

Thanks for sharing!

I belive the yellow cones are still included in the PNC-56 cone paks, at least they were in the last one I got a year or so back.

Then if someone wanted a true ' no painting' clone - Semroc tubes are white , get a black fin can , and have at it .

( unopened Longshot kit sitting here next to me, awaiting it's sacrafice to make a Challenger II, plus likely an Enerjet 1340 - I already have a Maniac in non-stock paint, just don;t try it on a G200 ...

Unless I;m mistaken, the Estes Mongoose is an exact copy of the Scorpion as well.

Been wanting to do a Scorpion clone for years, as a few friends had em in the day ( never had one myself) - but the decals are not posted, anyone have those * beg * :-)

(Please sned em to Scott and Phred, too, if someone has em :-)
