How to connect twin BL motor and esc

[skyfool]

Hi, I am going into EDF. Can I connect 2 BL motor with one esc? Is there anyone who can point me where to find diagrams for this connection. Thanks

Based on the way an ESC work, its is technically not possible to power 2 BL motors with one ESC unless the motors are both electrically and mechanically linked and synchronized in such a way that the ESC "thinks" that its only controlling one BL motor.
But this is just my guess and it requires quite an amount of technical knowledge to make it work. IMO it is not practical and chances are it won't work. So it goes back to my conclusion

use two ESC

you can share a batt. just make sure the batt can take the load.
you can connect a single Rx output to 2 ESCs through a Y-cable. No prob with that.
