Hi Serviceteam,
is it okay to connect ESC's BEC including throttle line to AUX and connecting SUMD including power line to RUD and connecting Ultra Guard to Receiver.
Ultra Guard works as buffer, that means in case that ESC's BEC voltage goes down by 0,5 volt Ultra Guard becomes active and will supply the whole system with power.
In that case reduced voltage is at AUX and full voltage at RUD - is that okay and best option ?
thanks and br

Hi,

your solution looks good and it should work well. But an ideal solution is that UltraGuard is at the same or close place where your main power supply (BEC) is. If you have no free ports in the unit then it is good to use receiver. Please check if the receiver power bus can handle higher currents.

To be perfectly sure, I recommend to perform BEC test with all the servos connected.
You can find it in our software in the Diagnostic tab.

Normally UltraGuard should not be armed during this test.

Hi,
Following your idea connecting ESC's BEC to receiver as well will end into one power connection from receiver to spirit system. Is that okay ? Looking at your recommendation, given in your manual, connecting two power lines to spirit system in case of Heli is bigger than 500 class.
I will do the check - that's a good idea.

You are right,
but I dont know what ESC/BEC you are using.
If there is possibility to connect master and slave cables, it is always better to use both.

For example this cable:

can solve some of these issues.

Hi, that's a smart solution.
Think i will leave throttle line at spirit system. Connecting ESC's BEC to receiver and spirit using an y-cable as shown. Rest of it as already designed.
So i will have two power lines to spirit
by the way it's Graupner +T100 G6.
