I have designed this block to get the 1 axis gimbal using the RunCam Split 2 camera and 9gr Tower Pro Servo. It works really nice, giving the ability to see not only what is in front of the model, but also what is below. It covers completely the camerra - usefull for sand or snow landing. There is the additional arduino mini driving the servo, it reads the FPORT frames and extract the throttle and gimbal channel. By reading the throttle channel, the driver covers the camera when the throttle is 0, usefull for landing. It also detects the failsafe and sets the camera position to record what is in front. This function could be realised by FC, but INAV sucks for the platform like Omnibus F3, it keeps the I2C bus (even if totally not used) and by this consumes the spare pins dedicated for driving the additional servos. Additional driver provides also the nice ability to drive the servo only for 3sec after detecting the change position request, usefull if the gimbal would be blocked by something - it will try to move only for 3sec, saving the energy, eliminating the vibration caused by "trying to move" servo.

Printed with PETG. It weghts 42gr with the servo (no camera).
