I love tractor motors! Once they get going in the right direction all is good.
The damage on the CSM's tail looks very minor. A few seconds of CA and it is back in the air. Hardly any soot as well! Is eleven motor, (8 tractor and 3 mid cant,) asymmetrically designed , ekranoplan flying going to be kid tested, mother approved?
KID: "Hey MOM, I am going over to the park with little Ricky to launch his ekranoplan."
MOM: " That's fine dear, just don't use all the baby wipes!"

A designed breakage. My inner bulletproofer is CRUSHED!
With the burn bans still in effect nothing is being launched locally, I started to feel like this guy:
What can be done? The only answer is to close your eyes, click your heels together three times and wish really, really hard: "THERE IS NO PLACE LIKE ESTESLAND!" Then you simply follow the yellow brick road and you are there! SCORE! CHILI BLASTER! A launch actually happening in the State! Headin' on down to Hudson Ranch, Yippee! Beautiful country outside Pueblo.
Show Jack to the SCORE boys and get a pad assignment, put Jack on the thick long 3/8" rod, load Jack on the away pad, insert your last old style Q2G2's, say a short prayer and then;

Jack landed real close to the pad. No damage!
Thanks to my Home Boy Fred for helping me to get Jack set up.
Jack got a lot of stickers in his hair. Will need a complete comb through.
Overall the flight went just as my mindsim for Windows 95 had predicted. No need for all the pre-launch nervousness. Flew the way any Duces should. It did telescope under all that F 15 smoke. The nose cone drag separated and deployed before the ejection charges went off, but all that drag on from the tail made it slow down real fast so all was fine on the way down. This rocket doesn't need silly ejection charges, it will fly just fine on plugged F15 -0's. Next time I am up before the Pad Fuhrer I will say "Yes Sir. no ejection charges required to fly this odd roc safely." On second thought, that might not go over so well.

It does look like winter time for a launch here in the Metro area. Our Scout groups are piling up with all the cancellations. If we do have a launch it will be getting hundreds of Scout rockets in the air. No room for silly oddrocs for awhile. Yes, Jack is just a happy go lucky, harmless kind of toy.
I'd approve that card based on the proven tapeworm designI bet it will recover safely too.
Dick knew all along! Just like Qui Gon Jinn knew who was going to win that pod race! He must have some kind of Master Ekranoplan

Good job with the flight! Glad you were able to find a solution to the burn ban problem. Less than a week to go for everyone to get their flight in!
No, No, not the Dark Side! Wait a minute, I thought clustered tractor motors were surrounded by the Dark Side! Maybe they bring balance to the Ekranoplan, tapeworms and scary Jack in the Box rockets?
Thanks! The solution was to head south to a club with a private launch site and a big annual event. The burn ban has recently been lifted in Park County as well. So off to South Park this upcoming weekend! Things are getting better all the time

Thanks for the photo. Yes, always a bit tense before a first flight.
Jack looks a bit scary...
YIKES!:y: Now that the design has flown I need to make a Hillary in the Box and a Trump in the box then have a drag race to determine the Presidency!

I will take my chances launching out in the open, can always run, duck and cover. Bunkers and sewers are full of scary clowns!
Headin' on down to South Park on the 28th for the Tripoli research launch. Two F 15 0's already plugged and ready to go. Still might be able to score 2 old style Q2G2's, but if not it will be old black tip Estes igniters from an 18mm motor package. Loving that slow speed drag separation. Loving that little bit of extra power from the plugged red label motors motors, even less fire danger to boot!
Little low power toy Jack in the Box will just be a warm up launch for the Tripoli research boys. With Jack, ejection charges are just for pyrotechnic effect. With all the down time from the burn bans I hope they have had enough time to home brew up some big and interesting composite motors. Maybe even a hybrid or tribrid, all depends on who can make the drive up.
I love it! :grin: Congrats on a successful flight and IMHO the "least 3FNC" build here! :clap:
Second flight at Tripoli Colorado yesterday:

Drag separation recovery worked fine, even in the thin air of Hartsel. Caught a bit of burn at take off on the outer tube just where one of the nylon cords attached, so the bottom BT 101 telescope tube went up on three cords, making for even more drag. Flew a bit higher with the thinner air and maybe a bit more power and less weight from the plugged motors. Deployment was a bit slower but maybe again the thin air and a tighter chute wrap than a week before. The good thing is it will fly on Hobby Lobby motors.

Thanks. But I still love me some 3FNC action!
Thanks. Gotta get me some of that clustered, canted, tractor and plugged motor action. 0 fins, drag separation recovery with a telescoping tail and googly eyes too boot. Small and Harmless Rocket Ship. Later on the weather cleared up for the big stuff which was awesome. Great day at the launch then some Texas style BBQ.
Thanks to the Tripoli guys and even the Pad Fuhrer who drove up to be at the launch. Thanks to all the other Home Boys who helped me out.
Thanks Skp! You got all the bits my video missed! Like the take off and the telescoping action!
Globbed the broken nylon string back together with CA, lost maybe half an inch in length but it should not affect flight performance, BT 101 still hangs straight. Had to tear up about half an inch of string on the exterior of the next tube in order to get the BT 101 to seat properly again so Jack could stand upright on the floor.
Jack showing off his flight scar.
Jack hanging out with Skeeterrific, who also had a zipper from being launched on a CTI F30 longburn. These dudes think their scars make them look tough and more attractive to the ladies!
So, after two flights what have I learned and what can be done to improve the concept.
What is that you are saying Jack?. . . Build a Jill in the Box?:wink: Naughty Jack!
I was thinking using square tube or balsa box fins.
Channeled kevlar for more burn resistant tail shrouds.
Plugged motors could be mounted higher with drag separation recovery, just have to stay away from NAR events!
Less smoky composite motors.
Higher level of finish, a crank fin, a music chip like on a greeting card.
Nomex cloth or mylar foil on the tail tube interstages instead of strings for more structure with less twist and flutter during flight.
Pyrotechnic effects - day or night, stay away from NAR and Tripoli events, hang out at the Pyro Club where "recovery" is a seldom heard word.
Night version with LEDs!
Upscale? Downscale?
Still thinking a telescoping Rattle Snake with a real rattle on the end would be cool.
A flying Matryoshka doll, you can always step down the telescope as well as stepping up like on Jack. Stacked cups would work that way too.
R2D2 with telescoping legs, just like the real one when they are in an XWing fighter.
A medieval illustration comet rocket.
A telescoping Hammer Head shark. You know where the motors would go! You would get a nice swimming action through the air! SHARKNADO!
A POP THAT ZIT rocket! Oh now that is just too gross!
And for Halloween there is always Oliver Cromwell's head on a spike!
