Length of motor wires effect performance?

[mjp8081]

So my plan was to mount the electronics at the center of the board and run the 3(x2) motor control leads through about 18 inches of 3w/12g wire (x2). I was wondering if there are any issues with longer lengths of wire (interference or resistance), esp. on the ESC OUT (to motor) end? Will it make motor control/acceleration less smooth for any reason? Is there any reason why I should reconsider the distance between the electrical components and keep wires short? I know the SBEC has a little shielder magnet.


I will post a build thread soon...thx

I have about a 12" - 14" motor wires from the ESC with no issues for one motor. For the most part, I think it's fine. The batteries should be as close to the ESC as possible, however.

Real problems only arise when you have different motor wire lengths. Long and short wires affect the timing, but all wires the same only have a bit less efficiency as far as I know.

I have one motor about 4-5" and another about 10-12" for a dual diagonal. On start-up I notice a delay but after you get the motors going it's pretty much equal.

OK sounds good--thanks guys, I will go as planned.
