Introduction

The Turnigy 9X is an inexpensive and highly hackable transmitter for remote controlled aircraft. This guide will show how to change a Turnigy 9X from Mode 1 (with the throttle on the right and elevator on the left) to Mode 2 (with the throttle on the left and the elevator on the right).

Thanks to Miro at iFixit for photographing this guide while I performed the work at Maker Faire 2011!

  • Remove the spring arm and spring for the left stick.

  • Push out the retaining pin.

  • Remove the retaining pin and spring arm.

  • Remove the spring.

I found it unnecessary to remove the retaining pin in step 4 or step 7.

In step 4 just detach the spring and then swing the arm vertical and it will slide off the retaining pin.

Image 1/2: Drop the retaining pin into the spring arm.  It is a loose fit, so it will freely drop straight through if the arm isn't held level.

I found this step to be unnecessary if you didn't remove the retaining pin in step 4.

Image 1/3: Hook the spring over the end of the spring arm.
  • Attach the spring to the plastic hook on the right stick.

  • Hook the spring over the end of the spring arm.

  • Line the spring arm up with the hole in the right stick casing and push the pin into place so it is flush with the side of the spring arm.

If you didn't previously remove the retaining pins then you can simple orient the swing arm vertically, slide it over the retaining pin and then tilt it down towards the spring. Finally hook the spring over the arm and it should be good to go.

My radio did not come with a plastic hook on the right stick to allow this conversion :( Stuck with Mode 1 now.

You are supposed to use the hook (spring arm) from the left side.

I just received my Turnigy 9X.

I ordered a Mode 2 Tx.

Sticks are ok (right stick stays in the center).

But when I open the tx, it says Mode 1 !!!

Left stick (up/down): elevator

Left stick (left/right): rudder

Right stick (up/down): throttle

Right stick (left/right): aileron

Is there something I can do ?

Make sure you hold the spring arm down when you push out the retaining pin. The pin required some force to move and ended up moving all at once causing the spring and spring arm to fly across the room. I almost didn't find them.

This is a great tutorial except...when you do this you still have your throttle on the right. You have changed the hardware and way the sticks feel but your throttle is still on the right. You need to make a programming change to switch to mode 2 left throttle. You must reverse which side the throttle is on. I found the solution here: http://youtu.be/sSWO_RrGDEk?t=2m25s
