| gyro stabilizationHello all.
Mike must have missed one of the videos we have up. There is one that demonstrates the gyro stabilization on our gimbal. If you go to our multimedia page, click the 'next' button once and look for the title Test Flight With 3-Axis Camera Mount, that video was taken with the AutoCopter airframe, manually flown by 'Rusty', while using the gyro's.
The gyro's work pretty well because of a few things... Our gimbal is large and has a lot of mass. It is also very rigid. Because of this, and the isolation method I'm using, the tilt and roll gyros are able to be mounted directly on the gimbal, and on the respective axis. The pan gyro can go anywhere on the gimbal head or on the helicopter.
Toward the end of the video you'll see Rusty do a slow pirouette while I was photographing him. I wasn't even aware he was doing a pirouette until I saw the landing gear come into view.
As to your other questions / comments, I'm sure Mike will get back to you shortly.
As far as the AirFoil mount, we have (or had) one here at the lab. This was an older generation, made with aluminum and wood (for the camera base plate). I never really flew it because it never really met the needs of the AutoCopter. I had always been looking for something more "integrated" if you will, rather than something that straps on. From what I hear form others howecer, as is apparent here, it performs well.
I do like, very much, the newest mount from Kevin at RotaryAerials (the GimbalMount). I've been playing with his mounts for some time and they are extremely clean, very light, very professional looking and they simply work well. The isolation he provides is good, but because of our application I haven't always used his isolators (because of mounting methods). I can submit that with simple 'T' mounts from Barry Controls, I was able to get down to a 1/125th with 35mm film and a 28mm lens with no blurring. I was happy with that. Using Kevin’s isolation, I would expect the results to be similar.
