Reversed pitch in my ArduPilot

Help! Ive got the same problem as the original poster, although I’m building a traditional helicopter rather than a quadcopter. The flight controller tilts the swash incorrectly in the pitch plane when the heli is pitched nose forward or back. It works fine in the roll axis. I set up the servos and transmitter as per the videos on the Arducopter instruction page, and am at a loss as to how to fix this. Meanwhile, the transmitter moves the swash in the expected manner. Can anyone shed any light on the problem please?!

Sounds like you reversed the transmitter channel when you should’ve reversed the autopilot’s servo parameter.

Problem solved; the issue was with the board orientation setting (I had assumed that the board orientation would have been automatically set once I’d calibrated the flight controller).
