I'm also having this problem, nvidia card, with the stock transx. Tried the transx built for 2009, but it complained about a missing dll call. Can't see the white plane intersection line or my orbit, so there's almost no way I can take off and hit the correct orientation. This is really annoying.

Ah, great. That's just what I was looking for! I wonder why it's not part of the standard functions?

Is there a way to directly get the vertical acceleration of a ship?

Definitely NOT just the XR2. I can't change the reference AoA within the stock DeltaGlider either. Thanks for the tip about the COG. However, I can obtain satisfactory results with the AoA control loop. If you didn't know, the controller is a PID controller whose parameters you can specify in...

The XR2's autopilot cannot do an inverted re-entry due to the bank angle limitation (+- 60 degrees?). Right or left shift gives the same result. The XR2's autopilot is not on, but maybe still somehow is intercepting keystrokes? I guess I would need to try it in the DeltaGlider or something to...

This is Orbiter 100830. Shift or no shift, the AoA reference change isn't working. Just to be clear, I am talking about the AoA/bank control loop for Aerobrake, not the one on the XR2 itself. The Aerobrake version number is 0.96.1.

The XR2. Also, I'm in Windows 7 64-bit.

After setting the reference AoA, you used to be able to change it with Shift+Num8 or Shift+Num2. Now that I have upgraded to orbiter 2010 and Aerobrake 0.96.1, it seems I can no longer do this. Is this a glitch, or am I the only one?

Awesome. Why exactly must non-spherical gravity be on for IMFD to work? Also, why doesn't the correction burn work as I expected? Again, I tried hitting "AB" again when the burn vector display said the remaining dV was about starting to creep upwards, but when I clicked AB, all the numbers...

You were absolutely right. I ended up reducing the flight time to 80-something hours, and got a much better trajectory. However, immediately after the injection burn, the map showed my moon perigee altitude to be increasing at a rate of about 2 km/s. After it got around 3M, I pushed "AB" again...

This is the XR2. I launched to get into LEO, then thought I could set up IMFD to do a free return with the moon. I was wrong. It seems no matter what I do, I can't get a free return trajectory that returns close to earth unless my perigee altitude above the moon is over 2 Megameters. I would...

You know, all I ever wanted to be was a commercial space pilot. Consider this my resume... 47lksSseMWA XR1 launch was from KSC 33. Lifted off and pitched past vertical then rolled to the correct heading. Used scram after mach 3.5 (the video doesn't show this). I settled out at about 1900 m/s...

If you have trouble finding a spacecraft that can get 20 tons into a path to Mars, it might be easier to launch the tanker into LEO then launch another craft to dock to it and apply the extra 4,000 m/s it would take to get it to Mars.

I recorded a short hypersonic flight of me in the XR1 from Cape Canaveral to Habana. However, during playback, the scram engines don't light up and their throttle levers don't move, and the apparent amount of scram fuel doesn't change. Is this a known thing? Too bad... it was a fairly cool flight :(

The way to do it is to try to maintain 125-150 m/s during the final stages of landing by changing the pitch of the nose. If you're unpowered, I think usually keeping the nose between -20 and -10 degrees usually does it. If you're powered, you can use the engine to keep your speed up while you do...

This is me at the joint meetings conference in New Orleans, 2007.

You don't need the hud. You should have had the Surface MFD up while you were landing. One reason is to look at the altitude and velocity, and the other is to keep an eye on the vertical rate of descent as you touch down (so you don't break your landing gear on impact). If I remember, 150 m/s is...

Usually gear fails because you are going too fast when you open it. Only deploy your gear in the last 20-30 seconds of your flight when you are going slowest. Normal airliners only deploy the gear during the last 2,500 feet or so.

Yeah, so how do you time your departure from Mars correctly so that the Moon will be in the right location for you to do the retro slingshot?
