Mick Baker Posted August 22, 2021 Share Posted August 22, 2021 Just read the article in RCM and E July edition re the concord one model, on pade 31 there is reference to a throttle ESC mixer that uses diodes which permits all the bec's to be used without shorts etc, can anyone point me in the direction of the circuit diagram/veroboard cuts. Cheers, Mick Quote Link to comment Share on other sites More sharing options...
Dad_flyer Posted August 22, 2021 Share Posted August 22, 2021 The circuit is very simple I think, just needs one cut for each diode on the + wire of each ESC. The receiver goes to the three pins at the top, the ESCs are side by side at the bottom. The first ESC is basically straight down, the second ESC has the three short yellow wires to step across the board by three lines, etc. Each ESC central + connection has a diode in series, pointing from ESC to receiver. The trace in the stripboard just needs cutting under each diode. What I don't know is which Schottky diodes would be appropriate. You need high current and low voltage drop ideally.

Allan Bennett Posted August 23, 2021 Share Posted August 23, 2021 There's a long thread on this subject (i.e. using two separate power sources) in another forum, which might be of interest. It uses a twin Schottky diode to make things simpler, and I've added LEDs to confirm that both sources are supplying volts. Quote Link to comment Share on other sites More sharing options...
