Dual batt/switch setup on one Rx?
I just read the latest issue of RCM the GP 300s PW Extra review and he used 2 batts and switches with one Rx? How do the batts plug into the Rx? isnt there only one battery port? I would like to do this set up on my Extra when I get it.
I am using JR 662 with R700 Rx. Thanks

Twin Batteries
Airframe,
this is possible but a short circuit in a switch is a more immediate problem. Either way diodes can be placed in the circuit to prevent any such action. Diodes will loose .5 - 1v so you need to use 5 cell batteries. This is exactly what I do on any model that can carry an extra battery. Since lots of my models seem to need nose weight its not much of a loss. You don't get much current out of lead!
Regards,
John.

John the voltage drop through a silicone diode is exactly .6 of a volt.
The diode also needs to be rated at or above the max current you are likely to draw.

Typically a cell will fail shorted or open.
If you have a 5 cell pack, a shorted cell will give you the equivalent of a 4 cell pack. A cell failing open will allow the other pack to fly the plane.
