I don't think the flight leg spacing and speed for the desired along/across track settings are getting properly calculated when using a custom camera. I usually can test this by comparing 70% on the X3 to 20% on my custom camera (1280 x 1024 x 12mm x 4.8um/pixel x 1s/frame) and count the flight legs. They can be 1-2 legs difference depending on the area but in this version they are off by much more. Am I missing a setting to apply the custom camera parameters for the flight plan? The resolution looks correct.
I'm using the latest MP Business v3.0.5.
