Re: [Paparazzi-devel] Strange Surging Behavior

Thanks Felix,

For testing purposes, I disconnected my throttle so that I didn't  
destroy my table / limbs if the motor started (yes, I should always  
just take the prop off). I didn't even think that I was removing a 5  
volt power source that gets hooked up to the TWOG! So while testing,  
the TWOG was trying to power everything on its own and overloading??

So am i correct to say that the 5V from the ESC (throttle input)  
actually powers the whole servo rail on the TWOG? ...When I remove my  
prop and connect the throttle input to the TWOG everything works great!

Thanks,
Jeff
