FJ, I'm not sure if this will help. I came across this post while looking for info on a new Tx and saved it as a word file. I believe it was posted originally by Quickster47, but I'm not sure.

6EXH set-up


Here is the basic setup I am using right now.

Setup for the Helimax Axe CP

PARAMETER Menu:
Swash Type setting: HELICOPTER(HR-3)
MODUL: PPM

CCPM servo channel mapping:
CH1: Right rear CCPM servo
CH2: Front CCPM servo
CH6: Left rear CCPM servo

Servo Reversing:
CH1 = Aileron Normal
CH2 = Elevator Reverse
CH3 = Throttle Reverse
CH4 = Rudder Normal
CH5 = Gyro Normal
CH6 = Pitch Reverse

Swash AFR:
AIL-> +65%
ELE-> -65%
PIT-> -37%

Throttle curves:
Normal: 0.0%, 36.0%, 72.0%, 83.5%, 100%
Idle1: 100.0%, 83.5%, 72.0%, 83.5%, 100%
Idle2: 100.0%, 83.5%, 72.0%, 83.5%, 100%

Pitch curves:
Normal: 40.0%, 45.0%, 50.0%, 72.5%, 100.0%
Idle1: 0.0%, 27.5%, 50.0%, 72.5%, 100.0%
Idle2: 0.0%, 27.5%, 50.0%, 72.5%, 100.0%

PROG - MIX1:
ELEV->THRO (Ch2 -> Ch3)
Down -20%, Up +20%

PROG - MIX2:
AILE->THRO (Ch1 -> Ch3)
Left +20%, Up -20%

Why mix throttle and aileron/elevator?

Cyclic movements take additional throttle to keep head-speed up, this is something I learned a while back from suggestions for the Hornet from Eric Larsen's home page.

Easiest way to test for yourself is to hover and just run the helicopter through some quick rocking motions, you'll be able to hear the head-speed drop.

The two mixes add throttle during cyclic simply to keep the maneuverability up, the stock radio doesn't do this, and it's why you hear so many people complain about a stock Axe losing head-speed in their first loops.
