Had this idea for a while:
Body consists of 2 BT-80 cones
18mm mount
good bit of nose weight
good bit of base drag :)
Looks to SIM out pretty good
Hope you like it

Very nice! I like curvy rockets. I think how it will fly is going to depend a lot on how the weight and drag is balanced between the 3 fins — could get squirrelly!

I think maybe you have a typo in the post. It says 13mm motor mount, but it must be 18mm.

yep - corrected :)
 
Did you get the shoulder of the aft cone to fit inside the forward cone just by cutting a slit in it? That’s pretty nice.

agreed on the D21 - might be a "heads up" flight :)

You might also check out some of the new Quest Qjets. C12 or more likely the D16. I haven’t used them myself, but I’ve seen some D16 flights of Estes rockets that are kind of heavy or draggy for Estes motors, and they looked pretty good.

I actually cut the shoulder off both nose cones, cut a gap out of the wider of the 2, to fit inside the bottom cone by about 1/3 inch, then drilled 1/8 inch holes around the cone, going through both the new shoulder and the cone itself. I then roughed it all up and used epoxy (the holes making epoxy rivets) :)

Sounds like a good technique.
 
Can't resist a challenge...

If the rocket really is 203g, then OR is much less sanguine about the possibility of getting the thing off the ground with a C6, which makes sense. That's pretty heavy for an 18mm BP motor.
 
ok - how did you do the ping pong balls??
and I added nose weight, so my sims will be even lower :)
