Almost You will have 3 wires to the motor instead of 2, and there will not be any wire from reciever to battery. There will only be a wire from ESC to reciever, as the ESC will feed the reciever with the power it needs to operate

Ah kk i understand for the battery but i dont get why there is a third wire on the motor [X(]

PS: look at the picture its the closest thing i have to a wattmeter (haha)

You have 3 more because brushless motors need more power sent into them that 2 wires couldnt handle. thats why you have to have a brushless ESC!!!

Ah ! good/fast awnser :P

Not really (I think hes joking with you).
To simply transfer more current you just use thicker wires.
The reason brushless motors has 3 wires is because they are essentially not a DC motor, despite the name (BLDC - BrushLess Direct Current). It is a 3 phase permanent magnet synchronous machine, or PMSM.
And since it is a 3 phase AC motor, it needs 3 wires just like any 3 phase AC motor.
The brushless ESC is a DC to AC converter, and its only a brushless motor WITH the ESC that can rightfully be called a BLDC.
A "brushless" motor without the ESC is just any 3 phase synchronous AC motor.
There is a lot of sinning towards technical defintions in this hobby, and I ususally dont care, like most other hobbyists.
But I understand this is confusing for someone not familiar with it.

Oh ! Yeah this is kind of confusing when you only know about old brushed motors and you enter the world of brushless :P But when i look at the ESC linked higher, i only see 2 wire going out the ESC, maybe i dont see the third ?

There is 3 motor wires, but the one connected the farthest to the ESC is laying underneath the 2 others in the picture, so its tricky to spot. You see it entering the ESC if you look closely.
If you click the link to the motor, I believe you can see 3 wires to the motor there.

Yeah the 3 motor wires ares easy to see on the motor link, and yeah i finnaly spotted the third wire on the ESC link :P by the way, what do you think about the kilowatt gauge a posted earlyer ?

EDIT: I found that my old motor was a 3mm shaft so i need the shaft adapter on the shaft side and the motor side, but i cant find one on hobby king..

Hi WaveZ

Yes, that's all good in terms of the wiring. By the way, Tamiya connectors are OK up to about 15A maxiumum. Other popular battery connectors for RC boats and cars are Deans and Traxxas, both good for 40Aor so. Beyond that most people use bullet connectors - 5.5mm, 6.5mm or 8.0mm which are good up to 150A or so but are more fiddly to use and more likely to get a short circuit because the terminals are not kept separate and the male bullet is exposed (uninsulated).

Also, what size is your prop shaft? - to check what kind of coupling you need.

Short cuts are easy to avoid in this case just need to add shrink tubes. And my propshaft is a 5mm.
