Hi John,

Sorry you have trouble setting up your transmitter.

I already contacted you in ( to 
try and resolve the issue with you. (it is easier in a real time conversation)

Independent of that, I assume you are talking about setting up a virtual 3 way 
switch using two switches and mixing. You should start up the GCS and see what 
the ground station reports. The default setup I use is using Gear and Flap 
channels. Where Gear is kill and Flap is mode. These are channels 5 and 6 

You should check your airframe file what channels you are using. The setup I 
have in my airframe file to be able to use those two channels is:

<define name="RADIO_MODE" value="RADIO_FLAP"/>
<define name="RADIO_KILL_SWITCH" value="RADIO_GEAR”/>

This goes into the radio_control subsystem section of the autopilot target.

You can compare that with the example ladybird_lisa_s.xml 
 example airframe file for example.

The default setting in the quadrotor_lisa_mx.xml 
 is using different channels.

Additionally, if your motors are turning without you explicitly unkilling 
(using the switch) being in ATT mode (using the other switch) and arming the 
motors (using the throttle stick at 0 throttle and full yaw) is worrying. You 
should make sure that the configuration of the "servo" outputs in your airframe 
file is correct and that when things are killed and unarmed the motors don't 

If you don't get throttle response even though all the above criteria are 
matched then I am stumped myself... :/

What you also can do is using the GCS settings tab you can switch into PPM 
telemetry mode and see what values Lisa/MX is receiving from your transmitter. 
(you can print the telemetry messages using the messages tool started from the 
paparazzi center) This might help you to see what the source of your issues is.

I hope this helps...
