All things being equal - Better ESC - lower temps?

[jamespl]

Im running the stock setup but with ec5 connectors and they get warm but what i find strange is that my 7.4v 5800mah 25c batteries run cooler than my 7.4v 5000mah 40c, both sets are turnigy. So how does that work? Just upgraded the motor connections today to 4mm. I was gonna try an x642 prop as the esc is always cool after a run just the packs and connectors get warm!

My understanding is that if you are pulling more amps through the wiring and connectors that they are rated for, you will have heat build-up that could then lead to higher amp draw from the battery and obviously, less efficiency. I think that is the same thing DRIFTAH is saying.... If motor and ESC are running under good temps, yeah, look backwards towards the power source. Battery "C" looks good for what you are running, so it most likely is a poor connection or under-rated connectors..... Just my thoughts....

if you are going to push things further you will need to at minimum upgrade to 5.5mm bullets throughout to help.super hot batteries usually mean you are trying to draw too many amps from them so possibly think about upgrading motor and esc and be very careful with overpropping,someone that has a stiletto may want to chime in and advise you on a good prop choice here.I have heard that a lot of guys are using the grimracer 42x55 mildly detongued and s+b possibly with a backcut as well.

Hi Everyone;

Newbie questions here. I have a stock Stiletto setup that is running quite hot (batteries and connections mostly). The setup is 1800KV Proboat Motor, 60amp Proboat ESC, running on 4S (2x 2S - 5000mah 40C Gens ace packs).

I want to experiment with props and increase my speed a bit and I was wondering if all things are equal would replacing ESC with one of higher capacity (say a Swordfish 120) keep my temps in check, and allow me a bigger margin of safety to experiment? I am told the motor is easily able to handle more load already.

Also if going to a better ESC is a good idea, is there any advantage to say going to a Swordfish 200A model or would that simply be overkill?

Thanks for the input...

Eric
