dual esc/motor setup

[BrianG]

Sounds like you need a HV and high amperage ESC along with a 1521 motor! That's a beastly truck.

The trouble is with dual BL is getting them to run perfect. One motor may have slightly different kv, and each ESC may be sending a slightly different amount of throttle. So, the faster motor/ESC will be doing most of the work and heat up more.

But yes, you should run twice the battery. After all, you are theoretically doublinig the power. Current will be higher than a one motor/esc setup, but a little less than two added together (less load on each setup).

Yeah, you'd run a Y cable for both ESCs, although it would be better to use CH3 mixed with the throttle channel so that you can fine tune each ESC/motor if needed. A simple Y cable means any adjustments to an individual setup would have to be done in the ESC programming.

If you use dual batteries in parallel, you'd want to use the "unslow" harness, or something like it, to make sure both batteries are drained equally.

Also, you'll need to remove the red wire on one of the ESC throttle cables (to prevent paralleling the BECs).
