RE: Please help....
Next thing to check if ch3 moves..
In the TX you need to check the pitch curve. If it's flat that will produce no movement on ch6.
The TX is in heli mode isn't it? I realise it is a heli transmitter, but it can be put in plank mode as well just as a plank TX can be set to heli mode. It is one of the basic parameter settings.
Check the pitch rate setting and the servo end points (if it has this setting).
Can't think of any other settings right now.
