CRASH CARCIS XVIII Regional April 17-18, 2010 Bear Creek Park, Lakewood, COStill time to build those points before heading to NARAM-52!

Joe, could you email me your current version of alphabet contest rules so I can edit and post. The new Hi-DEF contest rules ARE posted as of yesterday and the Triple Shot (H-I-J) contest rules will be posted tonight or…   Read more»

Rules need to be explicit whichever way they bend. Seems as if each and every contest is different enough to warrant specific and explicit options/rules for the contest to be properly administered. If there are two or more NCR member…   Read more»

In general, unless there is an overriding reason subject to wide discussion, consensus, probable vote at the annual meeting, and in the end, the judgment of the executive committee (President, Prefect, Contest Director, etc.), ALL contests are limited to NCR…   Read more»

Adrian,Thanks for pulling this together.1) is there a particular reason the F motor can’t use a motor adapter? It wouldn’t be efficient, but would there be any unfair advantage?Generally, the optimal mass will be higher for the higher-impulse motors. Since…   Read more»

Adrian,Thanks for pulling this together.1) is there a particular reason the F motor can’t use a motor adapter? It wouldn’t be efficient, but would there be any unfair advantage?2) I agree with 5a, not 5b. Would there be another entry…   Read more»

I’ll take a crack at writing down the rules, and people can modify The goal of the contest is to safely and successfully fly one rocket with D, E, and F motors in 2010, to the highest combined altitude for…   Read more»

Everyone can build to any weight they desire… I was recommending that each person’s rocket flies at the same weight for each of the three motors.The larger motors will have a higher optimal weight, while the smaller motors will have…   Read more»

Hey,Not sure i understand….If you can make a lighter rocket than me, why should we penalize you?David

If someone will write out the rules as discussed, (I missed some of this), I’ll post them on the rules page.

I’d suggest that the configuration and weight be kept as close to the same as possible. Just as the rocket airframe is optimized over three impulse classes, so should the payload, recovery, etc. For example, adding weight to the nose…   Read more»

Both of the Triple Shot Sweepstakes contests are still without any posted rules that everyone is supposed to follow. A Fixed weight is a good suggestion. Is that for a payload or the entire rocket? Motor weight will vary, even…   Read more»

A Raven, a beeline, and a battery can also fit side-by-side in a 24mm airframe tube, but you have to spread them out a bit more so that the total length is more like 2.7 inches. There’s also no room…   Read more»

By the way, this morning I’m working on a little 29mm av-bay design. It fits a beeline tracker (with USB battery charger), a Raven and a shared little battery all next to each other inside a 29mm blue tube coupler….   Read more»

I agree, nothing but the motor should change between flights. Using either honor system or measured weight would be fine by me. I always take my little scale with me to launches, and other people probably do too, so borrowing…   Read more»

Will the Triple Shot contests require a fixed dry weight? I think that would add to the design challenge and possibly make it more fair, but would require a scale or honor system that weights were fixed.

I’m hoping a BRB will be good myself.

The BigRedBee Beeline and Adept trackers will both fit into 24mm tubes. It may also be possible to put a Raven altimeter and a beeline side-by-side in a 24mm tube, but I’d have to check on that. I have bench…   Read more»

I’ve got a very light all-carbon 24mm altitude bird I built years ago to take the F and G records from John Wilke… after several near losses due to the small size and extreme altitudes I was getting on a…   Read more»

Depending on when Dr. J comes out with the 24 goodies, I’m thinking it would be pretty exciting to fly the 24 stuff. Adrian and I are already drooling over the idea, so I foresee some of them being flown….   Read more»
