You didn't show any collective in that video (throttle stick), but I think I can help. First thing you need to do is reverse your aileron channel (right front when looking at it from the back). When you do this, your aileron and elevator both are going to be backwards, but the key here is to get them moving together.
Once you reverse the aileron servo, you should have a swash menu in your Tx somewhere that has 3 settings, Aileron, Elevator and Pitch. Aileron and elevator are the cyclic movements with all 3 working together when you move the right stick, and Pitch is your collective or throttle stick. This menu may be called Swash AFR. Let me know if this helps.
