Which ESC for a serious 2S setup?

[Diegoboy]

I am wanting to setup my M1 Supercat S as a 2S boat. She is currently a 4S boat. I am targeting a 4100kv Neu motor. Every time I do the math, there's not an ESC that can handle the amps OR the ones with high enough amps cant handle 2S.

Here's what I know...
---Boat: Hydro & Marine M1 Supercat S 26.5" long
---Lipo: (x2 in parallel) 2S PolyQuest PQ5050-XQ 35C / 70C burst 5050mAh
---Motor: Neu 1515 1D (2000W surge)

---ESC needs 169A / 270A burst

Is my math wrong or is my motor choice wrong?

What do you guys suggest?

A t180 would be a good start but I've killed many over powered over amped set ups in my offroad car so aim high

On 2s Danny maybe a 240 lv useing any thing over 3500 has got me in trouble in a boat

Danny, fightercatracing has a 300A constant ESC that operates on 2-6s lipo. I'm not sure how heavy they are, but as far as current capability, I believe that's your huckleberry.

[Boaterguy]

yup, go with the FC
unfortunately the 400A one is only 3S+, not that you need it!

[antslake]

Why are you going to 2s?

[Diegoboy]

Yes 2S 2P (7.4v total) because IMPBA says N2 uses any motor on 2S

I have the ETTI Demon Rigger with a neu 1515 1D, CC240 on 3s 5000mah 40-50c can't remeber the numbers from the data logger, but do remember the temps were aleays good.

The Castle chart (link below) does not list the 1515/1D, but I would go with the Hydra240LV. It will handle 2S and should handle those bursts without balking.

It depends on the prop you put on her. Correct me if I'm wrong, but two 2s 5050mah lipos in parallel, wouldn't that be 10,100mah, beyond the 10k limit? I've got batts you can borrow. Regardless as you know, heat will be the issue. If you lose cooling for any reason, the wires are done and hopefully nothing else. On a Prather 225, that will do about 56mph. I would think she'd only pull 135-140A. I'd watch out for the half throttle stuff.

If you truly believe that your numbers are right, do you think the motor can handle that without overheating? It may make it. Perhaps call Don F.

Doing almost the same build, Drifter S and a Lehner, my numbers came out very close to yours.
Think I'll try a Castle esc.
Don't want to be the test pilot for a high amp 2s setup on one of the FC escs. Just haven't seen enough people using them yet to get a handle on them.
Learned my lesson with the Motley Crew. One boat I wish I had waited for some user feedback on.
What did Darrin use for an esc in his 2s Wildthing he set some records with last year? Can't seem to find the thread.
Be interesting to see what happens with these builds. Waiting for hardware for mine.
Cheers

That motor is fine... Ran the same motor in an N2-Mono and an N2-Sport Hydro for a couple of years without any issues using a Castle Hydra 240 ESC... It's a solid motor choice for a competitive N2 boat.

[RaceMechaniX]

In no particular order:

Castle ICE 240
Castle Hydra 240LV
FCR 2-6S 300A
T-180

I would recommend extra caps with running N2 power as the ripple currents are generally high.

Is the CC240 LV a 2S ESC? I always thought it was a 3S?

As far as I know it is... I've been using it for several years, using the BEC and everything, so if it's not, it is now...
