Two Brushless motors on One ESC….YES!

[Anbjorn]

I'm no expert but starting at 8 degrees on most motors can't too be far of. Then it stepping up and down from there. A degree or two does not make that big difference unless you ar running a SAW setup.
I would think the hotter (high kv) motors lower than 8 degrees would be the way to go.

It also states: IMPORTANT: Timing must be set prior to test/use. DO NOT RELY ON FACTORY DEFAULTS THIS IS NOT A PLUG AND PLAY ESC

So where do you start? Boaterguy, is your info speculation, or first hand with this esc? Without timing info from the motor manufacturer, you risk the 'failure' stated on the website.

Actually that's quoted from the HV ESC's. Timing isn't quite as critical on the LV ESC's. I'll update the information, thanks for pointing that out. A degree or two on an LV ESC won't make much difference.

If you're not familiar with timing, lipo LVC voltages, acceleration types or throttle curves, you probably won't like the ESC. It's fully adjustable and needs to be configured before being used for the first time. The factory defaults don't apply to all setups or preferences and could damage your lipos if run down to 3.0v or you could flip your boat if you're using an exponential throttle curve with soft acceleration set.

The first two developed hot spots under heavy loads (~140amps) and eventually led to failure of the PCB, so we designed a new PCB layout with more copper and bigger solder pads for the FETS which should resolve the issue. This process takes a few weeks for the new PCB and then a few samples need to be assembled, then component tested.... then field tested. So I'd say by 11/1 ish. Also adding a spark suppression line and some misc firmware updates.

The main purpose of the twin ESC is to simplify the wiring and appearance of a twin cat. I work directly with a group of electronics engineers that build the ESC's. They have over 20 years experience building electronic components and enjoy RC products themselves. I actually write some of the software as needed. Being a retired software engineer has its advantages.

Anyway, hope the information helps clarify things a bit. Carry on.

other way around

Ive read this entire thread, very interesting!! Will it work the other way around? 2 esc's to 1 motor? curious

this has been done with the lehner motors that have different windings (not sure exactly how they work but they have 6 leads).
you would need expert advice from either the lehner manufacturer or someone who has done it.

Long Answer;
It can be done, but only with a dual driver dual fet board ESC. Basically two ESC's that run off of the same PWM signal and power leads. Each motor requires its own driver / fet setup and needs to operate independently. Especially if RPM is not exactly synchronized. IF the shaft is shared between two motors, in theory you can, but in reality one will pull more than the other and they will sorta fight each other since the kv between them is rarely exactly the same. Some have gotten away with using two motors off of a single ESC in light use applications.

Short Answer; no

Again the answer is No, but the last "hopin i could" reply is one of those only seeing what they want to, again, its your cash, have fun with it. :)

What Fightercat has done is combine two esc's together for all intents and purposes, once additional fets and a controller are added it is no longer a single ESC, regradless of the power source application or single board. No lack of context and no comparison to apples and/or oranges. Not to take away from what FC is doing in any way, at least he pushing forward in the hobby in some way. keep the innovation coming FC, nice to see someone else putting their own money into the future of the hobby. :)
