Differential Thrust on Ch3 and Ch4

Hi guys,

I am building a micro plane with 2 motors, no rudder. I have a 4 channel receiver. Does somebody know how to program a Turnigy 9x transmitter? All I read is that the two ESCs are on channel 3 and 5 (or 5 and 6). I don't have a 5th (or 6th) channel. What do I need to do to run the two ESCs on channel 3 and 4?

I appreciate your help.

Im a spektrum guy so I dont know exactly how to do your transmitter but on the plane just plug one esc into throttle and the other into rudder then program the mix into your radio for differential thrust.
Thank you for the quick response. I know the video and this is exactly what I did. Unfortunately this Programms it to channel 3 and 5. But I need it to go to channel 3 and 4 (it is just a 4 channel receiver). So what I don't understand to assign the mixes to channel 3 and 4.
Ok. After some lost brain cells and a couple of hours in front of my beeping transmitter I got the solution:
Mix 1: THR --> AUX1 +100%
Mix 2: RUD --> AUX2 +100%
Mix 3: AUX1 --> RUD +100%
Mix 4: AUX2 --> THR -100%

In the end it seems logic. ;-)

Thanks for your help anyway.
