Re: [Paparazzi-devel] Funjet1.xml airframe software questions.

Dear Pascal

 

With the following Futaba 7CAP ~radio.xml settings the motor ran at full speed when I switched to AUTO2 when the throttle was killed.

Equally the throttle strip recorded 0% after this action.

 

However the motor also ran at fullspeed when I switched back to AUTO 1 and the transmitter throttle was set to zero towards me.

 

I have assumed that a min reading for the RC throttle pulse width is the same as down pitch (i.e. gimbal stick pointing away from my body in flight stance).

As described here: http://paparazzi.enac.fr/wiki/Radio_Control

 

I am not sure if I should reverse the RC transmitter throttle min/max levels and leave the funjet1.xml settings as they are now (see below) upon getting this result from your previous instructions/questions.

 

Your help in this matter is welcome.

 

Thanks very much

 

Stephen

Hi Stephen,

what happen when you switch to AUTO2 with throttle killed (first blocks of the basic.xml flight plan for example) ? Does your motor run full throttle ?
If not, it is the radio configuration which is reversed. Which model are you using ?

*2)* I reversed the funjet1.xml command section as follows to get the surfaces moving in the right direction from the RC transmitter as set out here:
<!-- commands section -->
<servos>
<servo name="MOTOR" no="0" min="2000" neutral="2000" max="1000"/>
<servo name="AILEVON_LEFT" no="2" min="1880" neutral="1500" max="1130"/>
<servo name="AILEVON_RIGHT" no="6" min="1170" neutral="1515" max="1980"/>
</servos>
Unfortunately the throttle strip setting always reads the reverse of the RC transmitter throttle stick position and the actions of the motor.
Motor off stick towards me -100% reading. and vice versa.
Can I change this?
