Post Mocha Setup - comment and question
My Mocha arrived and I'm getting it ready. No big deal, but as you do the setup make sure and check the screws in the aileron EZ connectors. One was missing altogether and the other was loose.

Just make sure you check it before flight or it could be a problem.

Also I'd prefer to use my own JR transmitter. There appears to be only one connection to the receiver. How would I swap out to a Spektrum receiver.

You can connect the spektrum receivers instead of the ppm receiver to the RC RX pins on your Lia. Where the primary receiver signal wire is connected to RX3 and the secondary to RX5.

You will also need to change the Lia airframe file (conf/airframes/esden/qs4_lia_a21.xml) in paparazzi (oposite of what is described here: ... rent_Radio) to use Spektrum. After you done this you can compile and reflash the firmware as described here: ... e_Tutorial

I hope this helps!

Thanks for the heads up on the linkages. I suspect they loosened during shipping...
