The Digikey Shottky diode has become obsolete. Here is a replacement diode, rated at 12 Amps.
This is not a common requirement, but a few wattflyer readers have been flying high powered twin motor electric models. And they may have wondered if those Castle Creations ICE uBEC (Switching Battery Elimination Circuits) can be parallel connected for reliability.
It is not a good idea to directly parallel connect these switching power supplies due to poor load sharing and/or interaction between the two uBEC's.
One way around this issue is to isolate these two uBEC's from each other by a high current diode. Problem is, the usual diodes have a 3/4 volt voltage loss in this type of application. Nowdays, the Shottky diodes are available that operate with about 0.4 Volts drop at 9 amperes.
One concern with this type of setup is that the two separate battery/ESC/motor power systems have a single ground point, the two receiver servo connectors. I've beefed this up by wiring in a piece of #14 wire between the two black wires of the Castle Creations ESC battery inputs.
Take a look at the attached photos and JPG's of a setup I've put together for a club members electric Gulf Stream model. This model uses a pair of 5000 Mah 6 Cell LiPos for battery power, a pair of 100 Amp Castle Creations ICE ESC's, and a pair of 2000 watt fans.
Last night we wired up the two electric motors, the ESC's and the batteries for the Gulf Stream model.
More work needs to be done on this Electric model, but it will show up in Wattflyer after its maiden flights.
