Twin Props

[David Marks 2Participant @davidmarks2]

I have just read an article in a model boat magazine regarding a scratch built model with twin props. The author states that both props turn in the same direction as opposed one going clockwise and one counter clockwise. Does anyone have any knowledge of which method is correct or are they both acceptable? I have also noted that R/H and L/H props are available. Again in a twin prop set-up should one prop be R/H and the other L/H? Can both motors be operated via one ESC?

There is a wealth of stuff on the Internet about this.

Briefly:
Contra-rotating is better than two running in the same direction;
You will need one of each RH and LH for that.
The props turn thus – Stbd Clockwise; Port Anticlockwise – both when viewed from the stern.
Yes, you can use one ESC. Wire the motors in parallel; if they both rotate in the same direction then reverse the two wires to the ESC on one of them.
If you need more info then go looking – it's a subject which is very widely covered in the minutest detail, so I'm not going to enter into any further debate about it.
