Does this mean I will get the same effect if I make up a Y splitter for a 1060?

Yes. 
 

if you don’t need the extra current capacity of the 880

1060 Should be fine to run dual parallel silvercans etc

Thanks! What is the limit? Is it 12T (limit of 1060) x 2 = 24T each motor? 

yeah close enough Rule of thumb  

silvercans are a “soft” 27t generally

but if you’re gearing them to the moon they’ll be close to stalling & can draw heaps too much current

@alvinlwh You can always place a fuse of your amperage choice in series just in case to prevent overloading (and potentially damaging) your ESC.  I know most ESC’s usually have overload protection, but I’ve read many threads where people mentioned their ESC just died. 

Never know how much the motor can dynamically spike in current draw when forced in real world driving.  

I remember my 5844 Pajero even came with an inline fuse on the MSC.

Can you explain that further? How many amps? How to work it out? 

Yeah, I suppose it would take some level of trial and error to find the right value... especially when the ESC has overload protection might be more difficult than it seems as I am sure heat build up also contributes to when the ESC shuts down.. hopefully temporarily.  

You can scratch off this idea as I don't want you wasting multiple ESC's just to find the sweet amperage fuse to use.. and perhaps on the 1060, you many never need one given the overload protection works each time, hopefully..

The 860 and 880 do come with a fan though, so maybe something to consider.

I'm running a pair of 15t firebolts off an 860, and it's been faultless.

(Also run a 15t firebolt on 3s with a 1060, so they're stout escs in my testing...🙄😁) 

Also, the 860/880 are 4s capable...

The chassis I am intending to do this experiment one, really, I am supposed to only use 27 - 35T motors as it has a fixed FDR of 5

Should know me by now, I'd look at that as merely a, serving suggestion....🙄

All depends on its mass and terrain.

Don't think I will go higher than 540 Torque Tuned when I go dual motors so will probably be within the safe (paper) limits if the 1060?

Mind the torque tuned are timed, so directional.

The 15t Core RC (same as the 15t firebolt I believe), pulls 20amp continuous, but upto 120amp stalled, so geared right and on tarmac, the data suggests they would be OK for a 60amp esc? But as its the upper end of its limit, a fan may be a requirement for future proofing.

If you've already got a 1060, then I'd maybe just get a cheap fan, and run it off a spare reciever port. If not, then the 880 might be a consideration (or research it, as the 1080 esc has some programmable options, so presumably the 880 has?)

Now, the issue for me to consider is at this moment, the 1060 is tucked in nearly into a space in the chassis. A 880 or adding a fan will mean it will no longer fit and I have to install an extension to house the ESC

That would settle it for me, 1060 it is!

I believe its got a thermal protection built in, so I'd run it, and see if it's OK, you're into an unknown, but it's great to be a pioneer! 😃👍

ahh! MST TCR 

yeah was wondering how one would go built FF+MR  

 

btw one avenue you might’ve not considered is, if your ESC is capable of 3S or 4S... run a higher volts battery & wire the 2 motors in Series (not Parallel). That’ll avoid “doubling” the current thru ESC.

Motor physics are never 100% linear relationship. 
 

Hot mod motors rely on high revs to produce their high power. Bog them down by overgearing and they’ll burn up real quick. 
 

Brushed motors aren’t digital devices either, even if you run slightly different pinions on a pair of equal motors or slightly different motors geared together they don’t seem to get too fussed (by our own experimenting). 
 

But TBH... these days with brushless & HV there’s less need to double up brushed motors for extra high speed running. At our recent Velodrome running someone turned up with a 6-wheeler pan car with twin rear motor pods. Don’t think it ran any better than the M07 with just a 5.5t running 2S... that little mini just cruised around like it was in rails lap after lap.

but RR motor mount does not allow 380.

hack it on with Grasshopper adapter plate?
