Video Shooting Capabilities

The installed Caddx Tarsier 4K camera comes with an ND8 filter which helps in correcting “jello” by allowing the camera to increase its aperture. The camera resolutions can be switched between 4K, 2.7K, 1440P, and 1080P. The choice of the resolution also depends on the speed at which you wish to fly the quadcopter. 4K recording captures 30fps and is recommended if the speed is slow. If the quadcopter has to be flown at high speeds then this resolution setting can lead to blurred recordings. In such cases, 2.7k resolution is recommended which captures 60fps.

If the quadcopter is being used in bright sunlight for video recording, then you should use the ND8 filter. This will reduce the light but keep the contrast intact, which will remove any jello effect and provide better quality video.

FrSky XM+ Receiver

Both these quadcopters detailed above, use the unique FrSky XM+ receiver. It is extremely easy to bind, binding is the process wherein a specific receiver is associated with a particular transmitter module. The XM+ receiver also supports the failsafe feature which is very helpful in the event of radio loss. The failsafe feature controls all the movements to a preset position in case of signal loss for a given length of time. Failsafe feature is highly recommended when the system is being used for the first time or it has been re-bound.

XM+ is a full range receiver like X4R-SB and XSR, with an added advantage of being much lighter than them. A typical XM+ receiver weighs only 1.6 grams. In addition to its excellent range and lightweight feature, the XM+ receivers have diversity antennas It supports up to 16 channels SBUS and the firmware is also upgradeable.
