Why of why did my hydra 240 fry..??

[Avanti]

What is it you propose we do? honestly not being an ass. I have seen many chinese products fail along with hearing about castle's fail. It stinks... literally! I am at the breaking point running a castle in my sv with 8xl. with 642 prop even it peaks well over 100A. I wonder if a 4 pole motor would be better. To loose some torque and spin a 4 pole motor might be the way to go?

exactly what douggie said try to follow what the key people do (and pray for the best).
Like I said mine has been ok so far, but every meet our club has another castle burn on someone (and not just newbs, but very experienced racers).
as for an alternative, there is no clear answer, but there are china 200a for $52 shipped (they would make a nice back up to have on hand while your CC is back at the factory)

key things to remember:
keep your wires as short as possible.
make sure you have good solder connections.
if you suspect there is water on your esc DO NOT try to give the boat throttle.
the CC hydras are water proof to 100' fresh or salt water, however if you opperate them while in water they will fry.

disclaimer: I am not claiming to be a FE guru just passing on the knowledge I have picked up along the way. JL

Thanks for the knowledge. So 4 pole motor is better than 2 in most applications. simple.
Edit: and keep to your basics: no running wet esc, keep wires short, start small prop. gotcha

SORRY to steer your thread away Ghost.

And why does that motor not look like any 8XL I have seen?

[AntronX]

the short reason is IMO the cc esc is a POS

I disagree, they burn up because people run overpowered or improperly engineered setups.

To the OP: Everything Castle techs told you is true. Feigao 8XL is rated at 87 Amps and here you are shoving 120+ Amps into it. About Fecalc, it calculated 67.72 A for my setup, but real life test showed 80 A. Fecalc is not accurate. Throw that motor away and get Neu 1527 1.5D to run on 6S. This motor will handle the power you were trying to get out of that 8XL. Get Eagle Flight V3 and watch your Watts.

Where can you get the 200A controllers from? I'd like to try one. Do they require a pistix?

[domwilson]

True. It's all black with black wires. Just one of those things that make you go hmmm....

[ghostofpf1]

Trust me..I scraped the label off for the water cooling jacket and it was a Feigao but I've had it for a couple years.Originally purchased for a Cen Matrix 1/8 buggy brushless conversion that I built and ran for only a short time.....

Still not seeing the 200 amp controllers on the OSE site.

I remember reading "Is there a way to check and see if my motor is bad"In the on the starting post.There might be a way to check it.Ok here it goes,Brushless DC motors are almost like AC motors,in the A/C biz the way I check for bad motors is by taking the motor out of place put it on the table pull your 3 leads out and put an ohms meter on it and measure resistance between the wires example(wire 1 to wire2,wire 1 to wire 3,wire 2 to wire 3)also check each wire to ground to check for an open winding example(wire 1 to motor case,wire 2 to motor case,)you should read resistance between all wires and read 0 resistance from wire(s)to ground.I have only checked a brushless motor like this one time and it seems to work like AC motors

re :

I may be off base here, but I noticed in your pictures that you're running a UBEC battery eliminator. If it was needed for the 200 amp controller because it didn't have a BEC circuit & you plugged it [ the UBEC] in to your rx with the Hydra 240 without eliminating the red wire in the Hydra 240, there'd be a problem that could have led to your meltdown.

I also agree with Jay that an 8XL on 5S is wrong for a 33" mono. Jay knows his stuff.

One last "long shot" : I've smoked several CC controllers during the Legg Lake weed season; wrap something around the prop, gun it &

O.K., one more thing : too much part throttle causes overheated brushless SC's.

There, my 2 cents

Reddy those are only the 4s ones Hi model has the 7s ones.

[ReddyWatts]

Yes, these are $50 and the HiModel ones are $70, both including shipping. They were referring to the $50 controller, but thanks for pointing that out.

Fluid is exactly right and every thing he said can be sumed up in 2 words "Improper Application". That is why 99.9% of cc esc's fail.

No one more than I dissagree's with the pricing but you get what you pay for. The Aircraft esc's are a gamble at best due to quality.
My 2 Cents.

Just a side note & I'm not trying to be antithectic. If I was to invest almost 300 in an esc I would damn sure study it's manuel like it was the gospel & dredge every forum untill my eyes burned for applied knoledge.
But thats just me.

[ghostofpf1]

OK..enough abuse already
Hopefully this thread helps someone else avoid my apparent mistakes in the future.
I know I've learned a few things .
SJFE: Ya know I read the manual front to back and nowhere did it talk about wire lengths or cautions on timing etc....and in order for you to be antithetic you'd have to be in the crowd that was not calling me foolish.Yet there you are standing amongst the majority
In retrospect I think my biggest mistake was abusing the motor and it took out the esc
thanks for the help

[ReddyWatts]

Thanks for telling us about the problem. None of this was meant to be pointed at you, it was directed toward the problem itself.

We can all learn from it.
