Rotors at different plane

ArduCopter Copter 4.5

Hi
I have recently started working on a quad design. I wanted to know whether I could have rotors at different levels.
Means, there will be certain vertical difference between frontel and rear rotors. Both the front rotors will be in the same plane, and the same goes with the rear rotors, but the rear rotors will be at different levels, i.e., vertically distant from the front rotors.

  1. What can be the pros and cons of this configuration?
  2. Will there be any affect on maneuverability?
  3. How easy will it be for my drone to cruise during missions, and will there be any effect on the overall flight dynamics?

The only issue with this configuration is the vehicle is not balanced on the Z axis so fast yaw will cause it to pitch. its normally not really noticeable unless you are stationary and yaw it at a high rate, which will then cause it to wobble.
