First thoughts about a design

I'd like some feedback about a design idea. The rocket will be a 3 x 29mm cluster, all Skyripper G69 hybrids. This will likely be one of the last hybrid rockets I build, so I want to do something memorable and unique. I've successfully clustered two of these motors repeatedly. I got a good deal on another motor set and some reloads, so I want to give this a try.

It would be EZ-PZ to make a 3FNC that would seriously outperform what I'm considering. Been there.

Here's a hack-up of the design idea. Rocksim says it's stable on two or three engines. One engine it goes just high enough to be risky.



The real deal will be all CF laid up in smooth curves. The nose cones on the pods would be fairings sweeping to the main. There would not be three independent tubes for the motors, the body will be one structure with voids for the motors. The wing fins would be CF over a foam core, with vertical fins a plywood composite structure. I know this idea will have a pretty serious tendency to weathervane, but since it's pushing to over 6K I wouldn't be flying it on windy days anyway.

Anyone flown something like this? Anyone see problems I should consider?

Thanks for the input.

I have nothing to offer, but I am curious. What size motors? Are you planning for glide recovery or traditional?

29mm G69 hybrids x 3. Standard dual deploy.

I thought you were looking into hybrid fireworks...

And where the hell are you getting 29mm SRS reloads?

Even blowing things up gets old after a while Plus I have a pile of CF, a quart of West System, and no other plans for the winter.

The reloads are stash, Al, plus I lucked into 2 complete packs a few months ago. I have, all told, 14 complete (including starter) and 2 partial left. This rocket will likely fly only once.

I also still have ten 38mm and two 54mm.
