This is a lesson about some revelations I had early on when learning my orientations. It's what I like to call coordinated and uncoordinated controls. Simply put coordinated controls are when you are using rudder and aileron in the same direction and uncoordinated controls are when you are using rudder and aileron in the opposite directions. For example:

Nose forward flight: Coordinated
Tail forward flight: Uncoordinated

Meaning if you are flying nose forward you will use rudder and aileron in the same direction whenever you turn or bank, and opposite directions with backwards flight. This becomes obvious and natural after flying for some time, but at first it's good to keep this in mind to help know what inputs you need to use.

Also here's how you fly funnels:

* Nose down funnels: Coordinated
* Tail down funnels: Uncoordinated

It's actually easier to just remember that Nose down funnels are the same coordination as nose forward flight, and tail down funnels are the same coordination as tail forward flight. This works out well because this also applies to inverted flight...

* Inverted Nose forward flight: Uncoordinated
* Inverted Tail forward flight: Coordinated

and

* Inverted Nose down funnels: Uncoordinated (same as Inverted Nose Forward flight)
* Inverted Tail down funnels: Coordinated (same as Inverted Tail forward flight)

---

So weather you're just starting out with some simple forward or backwards circuits, or funnels, or inverted flight just keep these coordinations in mind and it will help remove some of the dumb thumbs until it all becomes natural.

...
Here is another interesting tidbit of information about coordinations...

Whenever you are flying coordinated flight, pulling back on the elevator will pitch the heli upwards (or pull the heli up). If you are ever flying an uncoordinated orientation pushing forward on the elevator will pull the heli upwards.

So for example upright nose forward and inverted tail forward orientations, which are both coordinated orientations, will use back elevator to pull up...
