I am in the process of fixing my 550 due to the ESC burning up. Is there some type of device or way to protect my electronics in case my battery surges(if this is even possible) or my ESC fries again? I'd hate for this to happen to me again if there is a cost effective way to protect my gear.

TIA,
Andy

Yes, stick a Nitro in it.

And if you want even fewer issues, stick a flybar on it too.

As you know, if an ESC goes out, it will produce a soot material that goes into the motor, servos, and Rx. Most of the time, all electronics are ruined. My only suggestion would be placement of the unit and the purchase of a Kontronik.

Don't use the BEC function in the ESC...

Use separate BEC or LiFe/NiMh

It seems you are viewing the ESC as a consumable - they should last for ever!!

Did you get to the bottom of the last burnout??

Batteries don't surge! (Unless you suddenly increase the load across them, then the current rises, not the voltage.) This is not like the voltage spikes you see in your domestic mains supply..

you can try a fuse setup thats used in high power car audio...thats been the biggest issue so far...when a ESC decides to fart and short out there is no "weak link" in between the enormous power stored in the lipo and the melting/flaming ESC/Heli.

I have yet to see such a setup but I find no reason why one would not work considering that some of these fuses have 40V ratings and up to or over 200amps...and they are rated in DC voltage.

the only bad thing is that the car audio setup uses glass fuses on fancy clip or screw mounts...not sure how they would holdup under heli use though.

showing a preference will only get you into trouble, 90% of everything is crap...

+1 - and if the ESC gives up you can still auto it down.

This is my first 'larger' heli which uses a 6S pack.

I only had 40 or so flight on the esc. I would hope they last a bit longer than that.

I did not figure out what happened. I plugged in my battery pack to adjust my FBL unit and I heard a pop and saw a bit of smoke.

I like the Nitro idea but I am planning on going the gasser route in a month or so

It looks like the best idea would be to use a separate pack to handle my radio etc...

If the ESC is not a Jive, use a seperate BEC or 2s lipo direct. The thing is, no matter how you try and protect the Heli in the event of a crash, you never can. They are so unpredictable but protecting your Heli by using quality electronics is always a good idea

If a Jive or Jazz malfunctions, it just won't run. If any other brand, it won't run and has fireworks.

Andy,

Is this the Align ESC that burned up?

Do you have any additional recreational funds that can used for used/ new Kontronik? If so, buy it and forget about it.

I can help you locate a used one if you would like.

Thank you very much for the offer. I already purchased a Talon 90(Castle) ESC that I have installed. I have not been able to get to test things as of yet. I'm guessing the Talon may have not been the best choice???

I plan on purchasing a few more heli's in the coming months and I do not want to pour too much money into the 550 if I do not have to
