ESC Basically Melted

[green4191]

On my third flight today when I landed I tried to unplug the battery and the esc connector had melted to the battery connector. Had to use pliers to get it off. The battery is the stock battery. After looking over the esc it looks like it got wayyyyyyy hot. I've got 9 blade helis and have had more problems with this 450 x than I'll even mention. They told me to send it in (again I might add) and they'll look it over. I'm not about to send it in and wait two weeks for them to tell me yeah your right the esc overheated. At only about two months old this is bs. I've been fiercely loyal but after this problem and them asking me to send it in which will cost more than the esc itself I'm thinking my next heli from here on out will say "Align". If horizon is listening your losing thousands over the next few years because of your refusal to do what's right and just replace this thing which is under warranty! I'd be more than happy to have sent the old fried one in while they send me a new one.

Anyways anyone know of a better esc that I can put in this heli?

Maybe it's not just the ESC....

See if you can send the whole 450X in....hopefully the will replace it.....

Just be nice on the phone, and you're likely to talk them into it.....

I hope they give you satisfaction....

FWIW

Maybe just send in the ESC? FWIW, I've had to have mine replaced twice now. I have a HobbyWing Platinum-40A-PRO on order from Hobbypartz, it shipped today. The standard ESC on the 6HV kits is a HobbyWing and it seems that a really high percentage of people just go ahead and run them because they're pretty solid.

I've had good luck with the hobbywing platinum 100 amp I got with my Gaui 425. So a 40 or 50 amp Hobbywing ESC would be a good choice. I'm personally using a Castle Ice Lite 50 in my 450x because I'm trying out the governor. Seems fine and I have the servos (and 7200bx) running at 6 volts.

That was another thing I liked about the HobbyWing ESC. It's one of the few 40A ESCs, that I could find, that you can set the BEC output to 6V.

If you send me one, I will characterize it, including the voltage undershoot...the SBEC, I mean....
And I'll send it back, thoroughly abused...er...I meant "tested"....lol

[Rodney Kirstine]

LOL. I have 3 non-flying helicopters right now so I think I'll probably put this in the 450X when I get it.

Send it to them and you'll get it back fairly fast. Im on my second replacement so far, and both took 1.5 weeks from sending it off to arrival at my door. Both my problems where alot less severe and where replaced no questions asked. HH warranty is phenominal

Currently I'm using a YEP 45A ESC with the Scorpion -6 on a 12T, Governed at 3400 RPM. The ESC is actually a clone of YGE, and it no kidding has actual YGE firmware (will program with a real YGE card). The GOV works amazingly well. If you know anything about YGE, you know they have one ofthe best ESC GOV's around.

$30 for both the ESC and Prog card at HobbyKing, can't go wrong.

I sent mine in on Saturday and they shipped the replacement yesterday.

Rodney, while my response was joking, I would be willing to analyze a variety of internal and external SBECs.......free of any charge, other than shipping........

And if anyone could have a website, I would gladly perform the SBEC analyses and post the data...so that we all can compile a database of SBEC performance.....

Just a thought.....FWIW....

Thanks for the input.. I was in a hurry so I just replaced it with the stock esc and it's flying like a rock star. I don't know what the deal has been but I've had tons of trouble with this particular heli. I'll replace it with a better one soon. I just didn't want to send it in AGAIN! But since I replaced that I went ahead and went over every millimeter of it and went through the full setup for good measure. Now let's see how long it lasts..think I'll convert everything to deans when I change it out again.

EE has done some tests on the stock ESC/BEC and has come away with some good data. Basically it's a solid entry level ESC.

TBH, I haven't had any issues with my three 450X helis (I've had three Blade 450's but have two 450X's atm) so I'm keeping the ESC's stock for the time being as they are working fine.

So have i, to the extent that it failed again after all the upgrades i had done... this time the Ar7200BX (2 nd one in two months) again tested by HH and found to be faulty ( they sent a replacement)

Had my belly full of this crap!, stripped the electronics off... and Binned the damn thing.

Head/ frame etc was goosed as i managed to get it inverted before touching down just to make sure i would not be interested in re -building it made me feel better.. never will i buy anything more than an indoor heli from Blade.

Never flown such an un-reliable POS ever! in comparison my cheap as chips Tarot 450 pro v2 , with ZYX performs flawlessly every flight.

FA, so I take it that you won't be getting a 500X.....lol

I'm sorry for your bad luck....

No m8 definitely not.

[FailureToFly]

FA sorry about your bad luck....that is a really unfortunate.

Do you think the ESC was the cause and toasted you BX?

I had an initial 'fall out of the sky issue' but once I went 6v I've had a couple of great helis even after some pretty solid crashes.

I had an initial 'fall out of the sky issue' but once I went 6v I've had a couple of great helis even after some pretty solid crashes.

After the last incident i changed the stock ESC to a hobby wing 40 amp, fitted an external bec (rated at 10amp, set on 6v) step down lead to the tail servo, and on top of all that, i also fitted a TM1000 telemetry unit.

I had a bout 6 flights on it, telemetry always reported everything within acceptable ranges.
on the seventh flight i was just coming back to the field from doing a few FFF, and some loops, for the damn thing to start doing it's own thing again, ie i had no control.
no frames lost on telemetry, pack voltage 11.1v under load. and RX 5.9v.

That did it for me.... no more was i going to waste my time and money. Thanks to the many folk that i have met on here and done their best to help with the issues.

It's a shame as the heli does fly great.... i must just have had some gremlin with mine.HH confirmed the AR7200bX would not even bind when they recieved it, and replaced it again. (3rd one now)

[ritzcrakers]

never had a problem with mine. maybe the gear mesh is to tight?

M8, this heli has been to HH, had its ESC replaced twice, AR7200BX 3 times,, shall i go on?

Sorry if i come across annoyed, but i do know how to set belt tension after stripping and rebuilding this heli near 10 times in 2 months, infact could probaly do it with one hand tied behind my back, and blindfolded.

But thanks
