We have a winner!
Shows persistence and a bit of brainstorming pays off.
Other accepted answers would have been "Alien" or "Little Green Man"

Ummm...if Alien was an accepted answer, then Daveyfire got it first....

Wow! You are right! I didn't see David's post (was packing up to leave the office I think).
OK, I'll give out two prizes. David and Jeff PM me with your mailing addresses.

Well, the initial prize was a new parachute from my stash. I'll have to come up with another appropriate one for David.

Nah, don't worry about it... I kind of cheated, I have seen a rocket based on a similar alien figure before (at the January 2002 ROC launch, see attached), and when I saw the contours of the injection molded thingamabob, I knew it had to be one. IIRC this flight didn't go exactly as planned, so I'm looking forward to seeing you pull it off successfully!

I expected someone had tried it before. It's just too tempting. But he kinda cheated... adding a whole nosecone on top? Although his rendition looks very nice.
Successful. I am planning on it. As Pat G. said more than once on the LCO stand at LDRS30, "put a big enough motor in it and anything will fly straight."Planned motor: J340M (metalstorm) which should be especially nice at night.

Does anyone know of anyone who has launched a mannequin??? I was considering modifying a mannequin to look like iron man, and mount the motors in the hands.

The person set up across the fire lane from me at LDRS30 had a mannequin rocket in a bridal dress he called "Shotgun Wedding." Sorry, I don't know the name of the flyer, but I believe he flew it on Saturday.

I know, right? I hope yours has a creative deployment mechanism that keeps the exterior lines clean!
Far cooler than the J180T that he chose. This should be awesome. Looking forward to the rest of the build!
Certified, Don't ask!!!
Dam, I see these every once in a while, and old Halloween Alien, purrrfik for convertions.
Very Cool!

Finished the centering rings and bulkheads last night and in doing some of the trial fitting and, considering I want this thing around for a few years, I am gravitating toward using well nuts and bracket/grommet combinations to assemble all the plastic skin and lexan fins around the rocket proper. I want to provide some "give" at the connection points to relieve stress at landing and the durability of the epoxy-to-plastic connection is questionable anyway.
In addition I took a look at my Lexan stock and found it was at ZERO
Finally, looking at the head shape, I actually have more room than I thought in the nosecone "bowl" and thus have adequate space to attach "muffin pan" lead weights as needed (shown in use in this build).
Attached is the adjusted Rocksim file and a picture of the Lexan standing beside some carbon honeycomb I got in recently for a future high performance 98mm design.

This is going to be awesome, Tim. Looking forward to seeing her fly at MWP. The night launch alone is enough reason to make the drive.

With halloween coming, you should body-paint your grandson green and have him pose next to the rocket! What a great picture that would be.Here's another guy that is looking forward to seeing her (him?, it?) fly (my grandson

A small red flag raised on this build when I found out from my father-in-law that he has his band saw torn down. The band saw is what I have used in the past to cut Lexan fins. I tried doing this with a jigsaw with no avail as I got ragged edges (maybe there are other options?). So for now I am waiting for him to get it back together. Not panicking yet, as he's pretty good about getting things done when he knows there is a need.
In the meantime a few boring steps... 1) top two centering rings attached to motor mount, 2) motor mount attached to booster body, 3) inside fore end pic of motor mount, 4) "interface" CR attached to aft end of chute compartment, 5) inside pic of chute tube.

Tons of company over the weekend so slow progress. Surgery conducted on the alien (top of head cut off) and a bunch of fitting and sanding. To fashion nosecone a coupler tube section was cut with bulkhead attached shown on the left below. The base was epoxied on the end of the booster tube shown on right below.

My father-in-law got his band saw back together so the "log jam" was cleared. I cut fins last night. This morning cut slots and am now tacking them in place before applying the internal fillets. Pretty healthy span on the fins, but of course much of the surface will be "buried" inside the body.
No pat answers
On to internal fillets. And to just be sure I'm J-capable, I am adding a quick/dirty layer of FG across the fin/body tube fillet area up to about 1.5" from the root. Nice thing about this build, all the laminating and epoxy joints are hidden so they don't have to look good, just be functional.
As I'm contemplating final assembly, I am getting fairly paranoid when it comes to the disparity of materials. Polystyrene, Lexan, phenolic, wood, metal brackets, etc. At first I had planned to make as many connection points as possible. For instance a big heavy fillet where the wood base CR attaches to the Lexan fins, and then put L-brackets along the body and attach the fin exit area with screws and grommets. But then considering the variation in landing angles I began to worry with a wood base hitting and then the plastic body and then experiencing a torquing of the Lexan fins... So now I'm leaning completely the other way, i.e., minimizing the attachment points between disparate materials. So I'm down to 4 well nuts attaching the base plate to the body feet area and then another 4 well nuts attaching brackets to the interface CR in the neck/shoulder area. Of course the body would also be held laterally by the four fins through slots in the body, but there wouldn't be any specific attachment at the fin/body joints. I'm less worried about the top of the head/nosecone as it has more than enough attachment points and structure to hold the nose weight in place.
Any thoughts anyone has on the above would be appreciated.

Well, finally finishing the fin can. Aft end shown with CR now being inserted and then left to dry. The fin can looks pretty rough... not only due to the fiberglass layers showing through the clear Lexan through the fillet area, but also because I still have the plastic film on the fins. I'll keep it there until I get the final fit in the body to alleviate any errant scratching.

Coming along nicely. I was going to comment that you build fast, Tim, but I realize you just use your time very efficiently. I'd still be building the motor mount. (Cause I spend a lot of time day-dreaming about what it will look like finished.)
P.S. Is your grandson coming to the launch? It looks like he might already be emotionally attached to the little green man. You absolutely cannot crash it.

Yep, no reason watching paint, er, epoxy dry... Take a 10 minute break from work mix/apply/clamp and then back to work for two hours--then repeat.

Big learning experience cutting the fin slots in the body today. #1 it is nearly impossible to map out straight fins on complex curves of a body like this--not just an arc, you are dealing with undulations. #2 cutting four 9" slots in the bottom of the plastic body removes a lot of the rigidity of the structure. So combining the above, I do have the fin can inserted in the slots, albeit in slots that are not too smooth and wider in most places than they need to be, and I am now worried about the overall structure of the body under thrust. Thus I am going to flop back and move in the direction of tying everything together to get a more rigid structure around the MMT. This will unfortunately involve foaming around the feet area of the body and blocking some of the light that will be shining from the LED's, but, all-in-all, I believe the stability and safety of the craft is more important than the light effects. Since I will be filling some gaps around the fin exit area, Rustoleum 2X Key Lime Green will be my new friend.
