Making an RC electric boat
Ok I'm new to this site, and I just have a few questions I wondered if the community might be able to answer and help me with?
I'll just go over them in brief quickly to give people the jist of it all.
1) how do i wire two motors through one ESC?
2) looking at getting 2 of this motor
Graupner Speed 900BB Torque (6373)
Single ballraced, 12-pole armature.
Nominal voltage 12V, Operating voltage range 6-40 V
No-load rpm 6500, Current drain at max. efficiency 8A
but what does all that about the voltage ans amp usage mean to the more simple amoungst us? (me)
I have built a boat before, but it was a while back and with my fathers help, and he's an electrical engineer so he knew what he was doing.
thanks in advance to anyone who can assist with this

If you are looking for speed, then go for Brushless, even worth starting with a Ready to Run !! Take a look at this clip !!
They only require a couple of mods out of the box !!

It would'nt have to be "full" Size probably 1/4 scale would do for Cookee !!
