AirJib AJ6-800

Even though we offer the copter AirFrame AF6-800 as well as the gimbal CameraMount CM-M as two separate products that can be used completely independently from one another it almost suggests itself to combine both products to a complete system in the form of our AirJib AJ6-800.

Here we generally have to differentiate between a 2- and a 3-axes gimbal.

In the 2-axes version the gimbal is rigidly mounted on the copter, meaning the camera rotation around the vertical (yaw) axis is carried out by the rotation of the copter itself. Thereby the camera can not be freely rotated by 360° as possible with the 3-axes version. However, a 2-axes gimbal still allows for the recording of entirely stable videos since the roll and pitch axis will be compensated in any case. This configuration lends itself perfectly to one-man operation, meaning the copter's pilot simultaneously takes over the steering of the gimbal if such a need arises in order to rotate the camera around the horizontal (pitch) axis up- or downwards.

Thanks to an additional motor the gimbal in the 3-axes version can rotate itself around the vertical (yaw) axis completely independently of the copter. Here the gimbal has to be operated completely independently of the copter by a separate cameraman. This mode of operation allows the pilot to focus entirely on steering the copter and to fly set maneuvers in coordination with the cameraman.

With a free 360°-rotation of the gimbal we are inevitably faced with the problem that the bottom of the landing gear will at some point always enter the frame. There are two possible approaches to counter this effect.

The landing gear can either be furnished with retractable legs that will be moved by one or two servos or the landing gear is attached directly to the camera mount and would thereby always follow its exact movements.

We ourselves decided on the second approach as it offers two significant advantages. First of all, by dropping the retraction mechanism both the servos and the gearing are no longer an issue which makes for fewer components overall and eliminates a possible source of error. Secondly, a landing gear that has been attached directly to the gimbal is around one third lighter than a retractable one.

The landing gear attached to the gimbal has been designed in such a way that it only takes a few moments to dismantle it and mount the gimbal on a manual operation device instead.
