servo gimbal (for mobius on a 250 quadcopter)

this is a small, simple servo gimbal for my 250 quadcopter with a naze32 flight controller. the gimbal is very simple for several resons:
- servos and m2 bolts act as supports and pivot points
- no need for an additional gimbal controller, the signals are taken from the naze32
- the gimbal has just two axes
