Back to Joes idea on naming rockets after candy bars, why not Mr. good by Bear could be salted nut case or in my case…..PAYDAY!!!!Have funDway..

Another way would be to have interchangeable guts for the same rocket. A couple of well concealed screws should do the trick, I would think, if I was thinking in that direction, which I am not.If everyone would pay-up with…   Read more»

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…   Read more»

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….   Read more»

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,BEAR

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.

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

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…   Read more»

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…   Read more»

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,…   Read more»

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,…   Read more»

You’ll have to get permission for Hughes. 10+ years ago I launched there but also had the authorities show up a couple times.Edward

I met with Keith and two other guys on Tuesday afternoon to discuss things with them. They had NO sponsors at CSU at that time. They have my contact information. We discussed where to start since they have very little…   Read more»

I have some contacts in the CSU Atmospheric Department, maybe they could find an interesting payload to boost.Chad Moore

http://www.soundingrocket.org/Might be a good competition to start with – probably too late this year to do the NASA Student Launch Initiative program.

I’ll contact them and see what they are thinking – I’m guessing CANSAT or something similar might good for them.Edward

On the tips for carbon clothed tip to tip I’ve used Pro-Line from Wildman. I coated the leading edge for about 4 mm. Otherwise I’ve used Aeropoxy (Giant Leap) laminating resin successfully. I’ve hit Mach 2 with it without issues….   Read more»

If you’re going to do Mach 2.3, I would coat the leading edges of the fins with Cotronics high temp epoxy after doing the layup with regular epoxy like Aeropoxy or West Systems. I personally use aluminum tipped nose cones,…   Read more»

When doing this type of tip-to-top glassing, do you need to use special epoxy (high temperature) to keep it from delaminating at high speed? You said this rocket was simulated to go Mach 2.5. What epoxy did you use?

The video was pretty clear. I picked up some 2oz cloth and 30 minute epoxy. I have an old fin can I’m going to do some practice on. I’m still wondering what vacuum bagging does for you. Seems like you…   Read more»
