SN96,
Some kind of gyro/accelerometer combo I think. Not positive though.
linuxguy,
Yes that is my vid. EnduranceRC is my YouTube account. The wheel was the first stage of the project, its covered earlier in the thread. Headset is phase 2.
The below link has a video of something similar mounted in an RC airplane.
zoomkat,
Vrflyer, from the rc-cam.com forums is the maker of that video I believe. Doing this sort of thing on r/c planes seems to be a pretty hot topic right now ever since that video was posted on digg.com
cool project can’t wait to see more
That video was very cool. Makes you want to be small enough to fit in one of those RC plains and experience the flight first hand.
I once tried to build an ultra light airplane, but had kids, which changed everything for me. I had all the wing ribs made and they turned out ok, but some of the earlier ribs were a bit warped. To make a long story short, I spent $280 for the rib kit and wound up scraping it after a year and a half.
The application is done as of now, so the video is a little dated. So far the application I created is a full driving system. Steering wheel, pedals, pan/tilt control via headset, controls on the steering wheel re-center the camera, endpoint adjustments, inverted channel options, midpoint adjustments, sensitivity adjustmetns…you name it, it has it.
Ah…here is a screen cap, see for yourself.
What was that app programmed in? Visual basic? C#?
Very well done!
C++, created in visual studio
If only I could learn C++ 
You could probably use any programming language you want but I just chose C++ because I already had some of the parts done.
There are VB examples for the PCTx as well as C++ and there may be some linux compatible classes on the way. One of these days Id like to create a Java example as well.
Check out Microsoft’s Visual C# - they actually have a FREE version. I am actually looking at this as a way to create some robot interfacce software once I get a bluetooth link on Octabot.

There is also a free verison of visual c++ but I actually think it would be easier to learn C#. USB in C# is also very easy if you wanted to write your own controls.
