It’s hard to imagine how you want it to work. I can think of several ways of making a drone controller. Are we even getting physics involved here or you want to fake the rotation?
Try this, see if you like it:
You can do -45 to inverse it. Again, this is just a mere stub and more nuanced scrip is needed for a more plausible looking leaning. Multiplying the clamp by (or replacing it with) a curve may be enough.
If you need a proper, realistic & physically simulated drone movement, you will need to look into tunable PID controllers (not an UE related topic) - and then replicate the principle in the engine. Each propeller would need its own error correction.
