Here is another link or two on this topic: http://www.space.com/missionlaunches/090814-nasa-new-rocket-complete.html http://www.spaceflightnow.com/ares1x/090814stacking/ There is still concern about thrust oscillations in the solid motor, but I think this will turn out to be a good launch vehicle.

It might be spectacular to build a United Airlines one. The catch-cry for them used to be "Fly United, and land in pieces!"

Nice work Krusty.

Try eBay for decal paper. I think it is available with clear or white background. Just search for "waterslide decal" The Lexxjet kit is nice. Just up to sanding and painting mine. I have upgraded the drive to a 29mm with a custom machined slimline mount on the back of the boat tail. Probab...

Thanks for the invite. I keep thinking I would love to get down there for a launch, and also up to Serpentine sometime. Just family stuff limiting time available for me. When I get my "Possum" (ringtail!) finished I might have to bring it down there for the extra altitude. Work in progress...

Corona plus Booster

Just completed building a Corona and booster. Looks great so far, can't wait to see how it flies. Seems quite low mass, so I need to be careful with motor selection so I don't lose it!

I'm not sure if there is any increase in temperature at sub-sonic speeds. Looking at it from a conceptual point of view, above the speed of sound is where the compression of the air is occurring since the shock wave can't outrun the moving object generating it. Compressing the air is "doing wor...

Good idea Wombat. I was just using some of these today, chasing thermal runaway in a switch-mode power supply. Found the culprit. I find the stickers great as I don't want to attach thermocouples to mulit-kilovolt components! I have waaay too much on my mind if I am forgetting stuff like that! :?
