Letting the smoke out is one way to test it, lol. Hopefully it doesn't damage your controller.

Hey Terry, just think of it this way. You have the distinction of being the first man to toast a motor in RC boat history!:doh:
:bounce:
A motor with an 8mm shaft might help if the rotor is vibrating at full rpm. HET, NEU, and TP 4070 motors have 8mm shafts.
Many of them have the same protection. The Castle Ice air and marine ESCs both had/have over current protection. MGM and Schulze ESCs have safeties in place for reversed polarity, shorting, locked rotor, and motor leads falling off. However they will all tell you that any of these situation can still fry the ESC, regardless of protections within the ESC.
When I was using Castle Ice air ESCs in boats (before they released the Hydra Ice), I dunked a 160HV (essentially the same as a Hydra Ice 200HV) and the overcurrent protection shut the ESC off after spiking to just over 300A. I dried it out and it worked fine. Other people weren't so lucky though. Sometimes the overcurrent protection seemed to do nothing to prevent failure.
Ok good advice guys :thumbup1: So... ok just looking at the ESC's Steve has got here......
I can go the Seaking 180 for $119.00 - yeah.. that's doable.
Or the Swordfish Pro 200 Amp 8S for $129.00
What is the pick of those two in people's opinions??
Will I get away with those on 6S in the Ariane Hull? And those cheaper 6S Swordfish speedy's...... can you actually run em on 6S? And in a 36in mono With that Neu 1515 1650?
Not familiar with your hull, but I ran a 1521/1577kv on 6s in my 33" Cyberstorm(M445) with a SK180 for quite a while and it held up just fine. I haven't owned that particular SF, so I can't speak for it, but I have had some good luck with their other controllers.
Ok well the Ariane2 is a TFL Hull. 36 - 37 inches long. Nothing too off the planet :smile: Oh boy.... you can see my frikkin burnt cooling tube in this photo.....
Well ok... if you ran a 1521 / 1577kv on 6S with Seaking 180 then I'd wager I'd probably get away with it too in this hull with my setup. Most of my other boats actually run the seakings anyhow.
Add that to Make-a-Wake's advice/report above and the numbers are adding up for it.
I actually have 2 x Neu 1521 / 1860kv motors with the 8mm shafts that are going into a cat I have on the bench - which is partly why my spending cash is gone right now. But....... not for the Ariane I think.
I just wondered if the Swordfish - for the extra 20 bucks - has anything more to offer than the SK. If it's much of a muchness then I'd rather take the 20 into a seaside bar and get cocktails......

Terry, the T-180 is rated to alot more amps than the SF. We have used several T-180 esc's in 6S setups running motors up too 2300kv with no probs. We have yet to burn up a T-120 or T-180, but we sure have burnt up plenty of others... DJ
The swordfish 220a 2-6s is actually 10 bucks cheaper then the T180. The SF 200a 2-8s is 10 bucks more but its an opto, then you need to mess with an SBEC or a reciever pack for only 6s. I have an SBEC if you need one for minimal expense, but i'd go with the higher amperage 2-6s myself.
i would much rather a seaking 180 over a swordfish....
I add two 1000uf caps myself, just more confidence and probably longevity to the ESC as well.
I modded the cooling on one where the big empty space between the cooling tubes is closed off on each end and one intake and output fills the chamber for alot more efficient cooling. i used what i had laying around which ended up being aluminum L stock, the added side on the L just adds extra heat disapation i would imagine.
I'm sure it helps. I did something similar. ...

Nice! Mine looks like a "caveman" rendition compared to yours but its just for function, good job!
Yah know T180's had an issue of pre-mature thermal cutoff from my experience and a few others I spoke with, maybe it wasd the limited cooling system they made stock........
