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!

Hi Jeff,

BEC is an abbreviation for Battery Elimination Circuit, meaning you
eliminate the extra battery for the servos. It is basically just a
voltage regulator that produces 5V from your battery. As Maik said you
can just use the 5V provided by the BEC of your speed controller.

Cheers, Felix

Hi Jeff,

to me that sounds like your servos are drawing too much power with the
more rapid corrections of the AUTO modes. Especially since it works if
you have one or two disconnected.
If the servos draw too much current the voltage will break down and
the twog probably resets.
I would recommend to check that and maybe use an extra power source
for your servos.

Cheers, Felix
