[Paparazzi-devel] Strange Surging Behavior

[jlastuka]

Hello All,

I am experiencing some strange behavior from my TWOG after uploading a  
new airframe file. I originally had the easystar2.xml uploaded and  
installed in my easystar and had great results, we flew basic flight  
plans in auto2.

I have now installed the system into my Multiplex Cularis and have  
uploaded the attached airframe file (I got it from Maik, originally  
from Hendrix) and am experiencing some strange behavior. The problem  
occurs in both auto modes and also when switching modes. The system  
seems to get lost in surging cycles that last from 2 to 30 seconds.  
The ailerons, rudder and elevator all jolt about once per second and  
all radio control and telemetry communication are lost during the  
surging cycles.

Interestingly, if I unhook my ailerons, the problem disappears. And  
strangely, if only ONE aileron is hooked up, everything works as it  
should. Only when I plug in both ailerons do I get the erratic  
behavior. When I move my hands around the IR sensors the control  
surfaces move as expected, but then the system will suddenly go into  
the described jolting cycle for 2-30 seconds, then return to normal.

I have attached my new airframe file, as that is the only difference I  
have made from my previous successful settings.

Any help is greatly appreciated.

Thanks,
Jeff
