wiring diagrams

[weboyd]

I have a Turnigy 6 channel transmitter and reciever and have just completed a C-310B Cessna by Alien Aircraft. I am having a devel of a time getting the wiring correct. I can read instructions but cannot seem to connect the dots. Can anyone draw a wiring diagram for a twin engine electric using two controlers and one battery for me. Any help would be greatly appreciated.

Use a Y connector to plug both ESCs into the Throttle channel on your Rx.

Here's a video of same:

Thank you very much for your help.

Nice video on the two motor set-up

If you would want to use the BEC's from both ESC's, this will provide info on how to do it. You will not need the 9 amp Shottky diodes, methinks a pair of diodes on the order of 3 Amps each would do it. Let me know if you'd like part numbers on the 3 Amp Shottky diodes.

The video has a MAJOR flaw. You want to connect the batteries together - then connect both ESC's.

Doing it as recommended - may cause the one motor to quit before the other. BAD.

REALLY BAD.



Again parallel the batteries first then plug them into the ESC's.

My other recommendation - always disable BOTH bec's for twins and use a separate BEC or another LiFe battery for the airborne system.

I have watched MANY crashes on twins where one ESC BEC was not enough. MANY.

Agreed:
If you are flying a smaller sized model like the C-310B Cessna by Alien Aircraft, and your ESC BEC's are of the switching power supply type, the use of both BEC's along with the isolating diodes should work well. A club member had this setup in his twin 2500 watt (each) electric jet, using two 100 Amp Castle Creations ICE ESC's with their uBEC's. That diode setup worked out well.

That said, I would NEVER use a linear type BEC on any model with more than two LiPo cells in their battery pack. The risk is to high.

For the larger models, what works well is the Castle Creations 10 Amp uBEC, along with a two cell A123 or LiFe backup battery. My two setups (running 2400 and 3000 watts) now have over 200 flights total on them, with complete success.

Take a look:
