Check your PM, so you can save some calls !
The F1 and F2 functions are like a '3rd chanel', unfortunally not used in most PCB-designs, so you have to pick the signal directly from the RX6 C chip and build the 'driving-part' externally. My english is'nt very good, and it's hard for me to describe my thoughts....
As i said, you should first change only the transistor No.6, and try if it works. If the actuator has not enough power, you can cange the transistors No.1 - No.4, but i guess that is not necessary.

With a single transitor you can only drive a motor or an actuator in one direction. If you need to have 2 directions, you have to use an H-Bridge. Try to google it out (i'm to lazy to describe that in english... ).

I'm completely new to RC-Planes / Helicopters, but i've done lots of Bit Char G mod's ...
