| If you prefer to control the throttle with one stick and the attiude of the vehicle with the other stick, | ||
| set up your transmitter to send roll stick inputs to the :ref:`RCMAP_YAW<RCMAP_YAW>` channel (normally channel 4). | ||
| The rudder servo should be attached to the :ref:`RCMAP_YAW<RCMAP_YAW>` channel as well (normally channel 4). |

rudder servo is not "attached"...the TX should send rudder stick commands to the RCMAP_YAW rc in channel

Ok, let's fix the param description too, I agree on that word: https://ardupilot.org/plane/docs/parameters-Plane-stable-V4.5.7.html#rudder-only-rudder-only-aircraft

| Servo cables can be connected to any output of the autopilot, | ||
| but using the default channels 2-4 listed below is recommended. |

many autopilots do not provide servo rail power for channel 2 (or 1)

Which ones? This means the existing 4 channel guide is not correct, and also seems like a pain in the butt for fixed wing users.

actually having no servo power rail for the first two outputs is more convenient in many cases, usually the motor esc(s) are attached there, eliminating the need to remove the ESC BEC wire

again there is no default yaw stabilization....only roll should move the rudder

no need for this if done in FBWA...any RC reverses are discovered in that step

Ok, let's update the other guide then. I copied this from there.

| If in MANUAL mode the surfaces move backward with stick movements now, the corresponding RC input should be reversed. To do this, in Mission Planner RCn_REVERSED can be easily set on the SETUP/Mandatory Hardware/Radio Calibration page. |

you could move this expansion up to the FBWA test

Ditto on the 4-channel guide.

I set up a Parksone radian today, and decided to document some of the special things for a 3-channel plane. Some of the content was stolen from
RUDDER_ONLYparam description, which wasn't mentioned in the wiki.Currently, there's a fair bit of duplication with the 4 channel plane page. Perhaps it's modify the 4 channel plane to be "conventional" and have separate section for 3/4 channel differences.
