I've always wanted a V/S autopilot for launching the DG-EX. Something that can hold 20 m/s up to 64km then 0 m/s until orbital velocity. I've done it a hundred times by manually adjusting the trim, it's just exhausting to watch it constantly for an hour. I don't believe there has ever been a...

i believe a solid fuel rocket motor would be a better choice for propulsion. if compressed air was a better propellant, then government rockets and missiles would use it. 3000 PSI is much higher than the combustion pressure in conventional solid rocket motors. that means you take on more dead...

It isn't exactly just a few extra dV... it's atleast 3000 m/s and this would still be a pretty powerful rocket. perhaps an N class motor. The key thing here is that the burn will be short, we're basically just firing a motor without much else to it. very little weight over the fuel weight...

i've been working on my own music. bubblegum maybe? here's my latest two released tracks http://tellan.net/disturbia.rev2.mp3 http://tellan.net/whatever.rev4.mp3 and one that's in the works http://tellan.net/bow.rev.0.75.mp3

you need about 11.0 km/sec velocity change to get to the moon from the earth's surface. there is no fuel you could use that would fit into any rocket small enough to be considered 'model' rocketry that could provide enough DV to launch from the earth's surface. The coolest thing is that you...

i need to get some small kits to mess around with some more

m6 is disabled. There have not been new posts since June. The latest post in the off topic section is Arthur C Clarke dies. [ Goto Page: 1, 2 ]Simonpro272,548Sunday, May 25, 2008 2:29 PM and you're obviously trolling/flamebaiting. Troll Flame Baiting means you're making one/two line posts...

M6 is no longer active. It's safe to consider this the official Orbiter forum.

Hey Travis welcome aboard. Instead of introducing yourself here by announcing how sorry you are that you have an abrasive attitude, maybe lett everyone know a brief history of yourself with the community. Many of the m6 first folks are here now. It is an open forum, please express your...

The makers of the Dora show (a kids show) probably aren't smart enough to know what NASA footage they are using. They see it as just some more misson control shots. I think if they knew what event they were using video from they probably would not have used it. This would be like using...

Sounds like your video card drivers are corrupted - hence the BSOD when switching into 3D mode... I'd start with video driver updates. Something must have caused them to get corrupted however, so I'd do multiple full disk checks to determine if you've also got a faulty hard drive. Do more...

Orbitron is a must have. http://stoff.pl I've seen hundreds of identified satellites and numerous iridium flares.

a 26 acre ranch sounds like a dream to me... plenty of space to launch a high powered rocket even... When you build and launch them on your own property you do not need a LEUP or any sort of HPR certification. You do need to contact your local air traffic control tower to find out what type...

I've definetely seen my fair share of stupid folks on youtube doing things that just make you say WHAT? I dripped a very tiny drop of hot Rcandy ~250F on my pinky finger while pouring a grain once. It's sticky and doesn't come right off either and i couldn't drop the grain either without...

sounds awesome what were the chamber dimensions, the grain dimensions (outside, inside, length) and what size was your throat? I'd like to run it thru my spreadsheet see how your report compares. thx

You have a legitimate concern, but don't worry. The new orbiter versions will be mostly compatible with existing addons. Some addon developers may need to recompile their addons with the new Orbiter, but that only takes a few minutes. You shouldn't notice any major addons stop working, and...

Nope: All the motors I made were fired on Jul 4th. Unfortunately, the camera we brought down had dead batteries :-( So all the efforts went undocumented. I would like to make a clear PVC rocket at some point I'd bet it would be really bright, that stuff's wicked expensive though. I'll...

I've never tried these hydrogen rocket kits. Sounds fun. Usually sucessful gaseous or liquid motors are severely more complex than regular solid rocket motors. I'd need to see more specs to determine how to improve it. Need to know chamber diameter and length, exit diameter, fuel volumes...

I voluntarily installed vista on 3 computers in November 2006. It's still running on all 3. Never had to wipe, repair or restore. Obviously if everything didn't work great I wouldn't be running it at all. Yes it uses a little more RAM, but RAM is cheap. Upgrade to 2 Gigs or 4 Gigs and...

This sounds like an MTU issue. MTU is a thing that tells the computer how big the data packets it's sending can be. Try this: http://www.pctools.com/guides/registry/detail/280/ Try setting your MTU down more and more starting at 1450, then 1400, then 1350, until things work again. XP has...
