Updated list. We are getting there. May have one more here in Louisiana. I expect a few more as there are some participating in the TRF Traveler that seem to be under the impression that they are one and the same. We'll see.

It was brought to my attention that not everyone has Openrocket or Rocsim and I can't wrap my head around that idea. LOL. I had Openrocket before I had rockets to fly. So I am posting the sim results and a brief write up on said results. Now to those of you who know OR inside and out...I may have missed a detail. I have about 14 iterations of this thing in my sim folder so be gentle. Mass and Cg will change after it is assembled. I will mark the CP, and maybe empty CG, when complete and come back here with the updated file(s). Omitting the retainer doesn't help enough for me to fool with the hook. I will save some mass when I mod the MMT (yes I fixed that you witch hunters
) and fin tabs; and there are a few tricks I can use to shave a little here and there. A wood or paper CR up front will help some, the fin tabs will hold the MMT once everything is assembled. I think I can remove enough glass to account for the added mass of the epoxy.

The wedges on the front of the fins are there to fill the empty fin slots and give it a little bit better profile than just plain ole fins. Removing them helps a little with the mass and stability but not much. The fin tabs will be cut as needed so the file doesn't reflect them perfectly. This will put it at .98 CAL on the mighty D12, over 1 on the C11. Even the F39 has .69 CAL. If that doesn't sit right with you but you insist, smash a half ounce of clay into the tip of the nose cone. But this rocket at that altitude, may want a tracker and a few more eyes. These sims are run on a 3/16" rod, at 34" long. Kick that up to a 42" rod and they all get well over 40 ft/s. I don't know when it is necessary to jump up to a 1/4" rod or a rail but I would suggest the F's be flown on one or the other.
I am sending it the printed adapter. I loaded PLA+ and it prints wonderfully. I don't care if I ever see PETG again. I can play with the design and lighten it a bit but feel free to build your own adapter if you want a lighter version. Or even take a drill to one of the white ones I am sending. The white ones are plain PLA, black ones are PLA+.
I will put a simple 3/16 lug on one side, conformal 1010 guides on another. Printing interchangeable 3/16" and 1/4" lugs seems like an unnecessary complication. If the group thinks it necessary I will gladly do so though. I may again get the feeling to under-simplify things and look harder at it.
I invite the makers to design/print a coupler A/V bay for it so it can be flown DD if anyone so desires. I am willing and able but it wont be done quickly. If anyone wants to do it I can send the piece I cut off so they can get the dimensions correct. I can also send along an Eggtimer Quark.

I did my best with the RKT version. This is how it saves. I can go in and add motors and sims, adjust the dimensions and when I save it loses all that. You will need to reconfigure all the pieces. Sorry about that, but it is what it is. The drag, mass and Cp stay the same. The Cg changes for the better and the RKT version has better results all the way around.
