Flying Can UAV email details

I found the email response to my questions from the Flying Can UAV designer.

Here is the response he sent me. I responded to this email with a few more question but sadly he did not respond to my second list email questions.

Listed on the U-tube page he noted that 3 piezo gyros are used.

Please note his comment about using a light weight prop to reduce gyroscopic forces. I'm sure his intent here is to reduce yaw motion from motor/propeller mass with power changes, perhaps not to reduce gyroscopic stability as I suggested in my previous email today.

Hi thanks for the interest.
The Servos are digital.
The gyros are all set to rate, I had a lot of issues with heading hold on the yaw axis.
The entire frame and shell of the craft is constructed of carbon fiber.
The spars and frame are made from carbon square tube with epoxy glue.
The shell is mirror finished carbon fiber sheet, The use of this material is very important to reduce weight and maintain rigidity of the craft.
Brush-less motor, Li-Po battery pack, use the lightest prop you can find to reduce gyroscopic effect. I'm using cheap light plastic 3 bladed props. also balance the craft in the middle of the prop to save yourself headaches.
Have a new version of both craft posting new videos as soon as the weather gets nice.
Thanks.
