dual esc set up?

[Vin-m]

is there anything special that i need to do when setting a boat up to run dual motors ? is there a special way to wire up esc's so that the batteries drain equally thus providing equal power to both engines the whole time?

I assume you're building a two motor, two ESC ststem?

I'm not aware of any extra gadgetry or specific ways of wiring that help with dual-ESC systems. You've basically got two single systems getting their radio input from the one receiver, so you just need a splitter cable for your Rx to ESC. If your ESC's have BEC's then you should disable one (bec) by pulling the red wire (please check that) from one of the ESC -> Splitter lines. You only need juice from one ESC to run the rx and steering servo. Other than that, you wire each Motor -> Batt -> ESC exactly the same way as a single drive system. As each motor should be doing the same amount of work, your batts should discharge evenly. Even so though, you'll probably need to time your runs to some extent because one LVC will likely kick in before the other. No biggie if it does - should still be able to cruise back to shore. Got a Zonda Cat with dual motor & ESC which works fine. Just remember to get the counter rotating drive cables and props! Then be careful you spin each driveline the right way :).

I have not built a twin yet but i was told you can run the batts in series and then hook the red to the red and black to the black on both esc's and then feed battery power to them. That way your not feeding two different systems. Is this true?

Disable the BEC on 1 of 2 escs, or both and run an rx pack. Then get a decent Y-connector, and you're done. I have built a lot of twin cats, 1 battery to each motor/esc combo, power is always dead even when comparing one to the other, voltage identical after bringing the boat in.

If the boat is built correctly there is nothing wrong with each system providing independent power to each prop.

Keep both sides separate. There is no reason to tie the two together unless running at an IMPBA sanctioned event, where it's required. If there is a failure, the issue will be isolated to that side only, protecting the other. As long as both powers systems are identical and the controllers are calibrated correctly, both sides will run in unison.

What if, say I'm doing a twin a small hull that I want to run 6s on each motor but don't have room to run two 6s packs....just enough room for two 3s packs?

You can wire them in series and parallel the controllers if the packs are large enough to handle the needs of both motors. The only issue is if there was an incident like a motor failure that takes out a controller. With both ESCs in parallel the likelihood of that motor taking out both controllers is there.

thanks for the help wiring it up atm
