For XCAM Circle flights, the XCAM must be rotated from a nadir (cameras pointing down) position, to an oblique position (cameras pointing out at an angle).
Once you have completed your circle flight plan, the software will show you the roll required for the plan. You can access this information:
- During the Flight Planning Phase after you have selected an aircraft ground speed.
- By opening up the WaldoAir FCS and selecting a project in Sim Mode. It will pop-up with the required angle.
To rotate the XCAM to the required angle:
- Fix the XCAM in the strut cradle as normal.
- Check the cables attached to the XCAM have enough room to move.
- Loosen the straps slightly to allow movement of the pod.
- Rotate the XCAM to the required angle. The use of the tilt sensors in a mobile phone work really well for this. Rounding to the nearest degrees is ok.
- Tighten the straps.
- Check your installation.
There are many apps on the Google Play Store and Apple App Store. Choose one with good reviews. Here are some examples:
Here's an example of the pop-up, which shows the required angle of 54.2 degrees:
This means the XCAM should be rolled 54.2 degrees from its vertical position, like so:
Firstly, there are a few things to note:
- The XCAM FCS is designed only for clockwise circles. Therefore the XCAM must be mounted on the starboard (right) side of the aircraft, pointing out towards the right.
- Check your fitting position for obstructions. You don't want your XCAM taking photos of the aircraft or landing gear.
