Default Multi-Engine/motor brushless ESCs

This is probably on the forum someplace but I couldn't find it in a search. How do I wire two Atlas brushless 12A ESCs? Can I use the BEC circuit? I am putting two Atlas AM2308/14 motors on an Albatross.

Thanks in advance for your help.

The recommendation for two brushless motors is an ESC for each motor.

If both ESC's have BEC, then remove one of the red (+ive) wires from one of the ESC's Rx leads. Having two BEC's feeding can be detrimental.

The easiest and neatest way is the prize up the little plastic retainer in the connector and withdraw the wire and socket, tape/insulate it, not cut the wire. That way you can simply plug it back in at any later date and use the ESC in another model.

Both ESC Rx leads can be connected to the Rx via a 'Y' lead.

Both ESC power in leads can be paralleled to one battery or connected to individual batteries.

I believe there is a recommendation is to keep the motor to ESC leads shorter than the ESC to battery leads if possible, but that's not always possible with multi motors.
