In the latest development with our quad-rotor project, we attached the main controller board. It has three gyros to maintain its orientation. These types of gyros don't spin like we are used to thinking. They have components that vibrate back and forth.
When something is vibrating it tends to vibrate in the same plane and is resistant to rotation. The potential problem is the rotor motors can put out a lot of vibration into the frame. This vibration could interfere with the gyros (although I have heard that some people have had success not worrying about it). To dampen vibration from the gyros, instead of mounting the main board directly onto the frame, T cut out part of a "Dr. Scholls" foam shoe liner and I mounted the board to it with 1/2" 6-32 nylon machine screws (I am trying to avoid metal for weight and radio interference considerations). Then this was mounted to another cut out shoe liner, which is attached to the frame (in this case temporarily with small binder clips). I could have just glued the parts together but at the moment I want to keep things flexible so I can take it apart and redo it if necessary. Anyway, the plan is that this set up will be sturdy enough to work, but will fully insulate the board's gyros from motor vibrations.
Above shows the main controller board partially attached.
Below, the main board fully attached using the shoe liner vibration insulation. This one also has one of the rotor motor micro-controllers plugged in. That is the next thing to get sorted out.

Quad edition a better model. technology are effected in your future life. We are more interested about new technologies .I like this becauses of qualcomm’s latest soc hardware. thanks
