Now that I have a radio with the wonderful feature to let the trainer port only take over certain channels, I was able to build myself a head tracker. The electronics from an E-Sky 0404 radio will have to suffice.

Testing the concept.


I reused the parts from the sticks.


The Hat-Tracker done! I removed most of the unnecessary components from the pcb and soldered the pots to channel 4 and 5. In the hole at the end of the plywood stick I’ll connect a retractable keychain that hooks into the radio.


Here you can see the underside.

I have tested it and it works great! I hope to get some video of it in action soon to share with you.
