Tyler and I are thinking about using a 29mm config on a Madcow Screech for the alphabet contest. Question is is there an adapter to start off with a E motor (24mm) that has an adapter to fit into the 29 mount? That way we could run the alphabet E-I. CTI has the 29xl as far as we have investigated.

Dave;
In the interest of un-fairness and giving myself a greater advantage, I will tell you that it cannot be done and there is no possible way for you to make one yourself from scratch. In fact, if I were you, I think I would give up now.

Dave,
Always easier to adapt a motor tube down a size than up. Estes has a simple product that surrounds the motor and does just that. They already have sleeves that make an 13mm motor fit comfortable in an 18mm tube, and an 18mm sleeve type adaptor that fits comfortably in a 24mm motor tube. Soon there will be a sleeve that surrounds the 24mm motor to fit comfortably in the 29mm tube. Next size up make sense. I’ve got a crazy idea of splitting a tube so I can easily fit a 29mm motor in the 38mm airframe. Otherwise, all manner of possibilities to make this contest a challenge. Same airframe, different internals and possibly a sealed bay to add/subtract necessary weight for balancing. But Bear has the right approach. Quit now while you’re ahead of the field.BEAR
I agree with Joe completely, and want to emphasize what he said, because of his great wisdom and experience.
Other than that, I will not tell you that I have a cheap drill press, that I have a circle cutter for that drill press (up to 6 1/2″ diameter). I will not tell you I buy large sheets of 1/8″ and 1/4″, also 1/2″ plywood (depends on the motor size for which I would have used if I was doing something like this, which I am not) so I can cut rings out, (which I really did not do when we were building that big rocket in that hanger and that I made six sets of rings for motor adapters for the outside first stage motors).
I will also not mention that if you were to look in one of my tool boxes, you would find motor adapters for 18mm to 24mm, or 24mm to 29mm, 29mm to 38mm, 38mm to 54mm, or 75mm up to 98mm, or 75mm down to 65mm, or any size in between. And I am sure you would not see that they are in various lengths so that I can use spacers in long ones for short motors and vise versa so that I can adapt to just about any situation.
I would really suggest that you quit while you are already behind. 😈 😆

BOYS! BOYS! Such trash talking, and so early in the contest. NCR has needed 2 things, a great flying season and a good contest. I hope plenty more of the NCR faithful put their money where their rockets are. I know Dave Way has a prototype built, we will be testing it this weekend at the Brown Mud Test Range, just outside of Delta. And then there is my bird. I am WAY to humble to brag and say it will win, but I named it “Taken Candy from Babies”. 8)

Yeah probably rocket candy. Salt Peter and sugar. Sounds rather bitter to me!

Dave,
Joe and Bear forgot one key element. Pay your entry fee THEN give up and quit! Got you all beat anyway, been sanding all weekend. Calling this one, the Alphabet King.
BEAR
We have to remain positive and try to help wherever we can, so if you can put in to the winning purse, as Mr. Hounddogger suggested, before you drop out, that would be greatly appreciated.
Best regards,

Not to sound over confident, but I’m thinking of entering twice,(two different airframes) so I can double my chances of winning! And if Dave Way is playing, make sure Marshall isn’t the chief architect/designer. That kid has some serious smarts. Yo Tim, no one likes “Sweet Tarts” or “Sour Apples” or those nasty “Lemon Heads”.
Another great contest – name your rocket after nasty Halloween Treats – like “Baby Ruthless” or “Three Rocketeers” or “Silky Way” or “Bit of Money”. The posibilities are endless – “AP Joy” or “Mister Crash BAR”.
Dave Way
Gentlemen,
Just wondering how I got Thrown into this conversation.
My prototype should be prototypes. And in the interest of unfairness, I am thinking of several identical airframes with different internals that can’t be distinguished from one another.
What I can’t achieve with my good looks and smart son, I can achieve with caginess and underhanded cunning.Good luck.
Dave Way……..
