When i first started with boats many years ago, speed controllers were basically a rheostat type circuit board and a wiper arm on a servo.

I have been looking at ESC's but i notice most of them have 3 output wires, and also they dont seem to mention Gel cels (lead acid).

Question 1. What are the 3 output wires for and how do they connect to a small standard motor?
Question 2. Do they work with Lead acid batteries?

Two wires to battery.
Two wires to motor. Solder on.
I wire to receiver.

Yes you can use SLA batteries

Hi Lee

       ESC   3 wire = Brushless Motors ( Fast )

       ESC   2 wire = Brush motors all speeds

       Have a look at ACTion web site with all the info sheets 

       http://www.action-electronics.co.uk/home.html

 P.S.
         Where are you in the world

       And  HI to the world of model boating

Dicky,
Not being pedantic but it is usual to not use red and black for the motor as it is the same as the battery connection.

Bob not to be pedantic but who was it that ran out of fuses because he connected the red wire to the black terminal several times and had to bum a spare fuse off me at Whiteley ?

That apart, I'm colour blind anyway so it would not make any difference what colour they were.

Cheers all,

I need a two wire then for a standard brush motor, it all makes better sense now.

Thanks
