I'm thinking a kick-ass boost to get some mass moving past mach followed by some sustaining burn to keep the momentum burning and that mass to keep it coasting. My preliminary designs on Rocksim are v...

Tim, sorry if I'm not seeing the problem... Paul is selling old style AMW cases and re-labeling or making CTI-compatible cases. Last I heard all Paul's propellant is made by CTI so whether it's for an...

Damn John... I bet you could do something about that K record with something like this. I bet the ticket is going to be optimizing weight. Put a little mass in there, make it short as possible so prob...

All commercial and government liquid fueled rockets use active guidance systems, usually using gimbaled exhaust nozzles and in some case entire combustion chambers. Gyros were used as the reference fo...

I would suggest morning. As always, I'll be happy to drive the trailer up to the North Site on the Thursday before the event and manage range set-up. I can also handle recharging all the range boxes. ...

You really need to get peel-ply from a composites vendor such as Fiberglast.com or Mr. Fiberglass. Aside from the fabric material itself, peel-ply is typically coated or impregnated with chemicals to ...

For the most part, the rules set down by Doug look to be extremely solid and will promote a great competition. Team projects were not addressed in those rules and the entry fee is one of the few aspec...

Doug, As always, utterly superb pictures. Warren

Thanks Doug for the post. Yes, there is an Upscale Contest in the works and it looks to be a very fine contest. Rules are pretty well fleshed out - again, thanks to Doug for coming up with this idea a...

As I read the proposed rules, it doesn't matter whether a particular upscaled project has been done before so long as YOU haven't built the particular rocket before the contest begins. W
