connect PX4 (type:PX4Multirotor) to custom drone (type:SimpleFlight) in UE4

[MinIN-git]

Question

What's your question?

How to connect PX4 (type:PX4Multirotor) in custom drone (type:SimpleFlight) in UE4. And

Include context on what you are trying to achieve

I want to change default camera position, setting at the initial stage Multirotor. And I had two ideas:

1. Go into .cpp and change the camera settings there
2. Create a new copter (in setting json) and connect px4 to it

Context details

I need a more general solution (ie via setting.json), but I don't understand how to combine type:PX4Multirotor and type:SimpleFlight.

Include details of what you already did to find answers

My setting.json looks likes:
