Smoking a Turnigy C35-30 - 1400kv Bell Motor

[martyisnuts]

i bought this motor no prob but the 40amp HK esc i bought crapped out on bench test.HK has some good buys but i don't buy to much there anymore.I may start buying there if they ever get a canadian warehouse up and running.

[thechoosendude]

Please tell us your ESC, prop and battery... also what ESC settings you had. That way one can determine if was truly the motors at fault.

Looks like a few Turnigy motors I bought. I do believe in the saying you get what you pay for. For now on I just stick to Eflite. Two motors have done that to me. I am not taking a risk anymore. I know the brand names cost more but they have all worked great with no problems and Horizon Hobby has great customer service if you have a problem unlike Hobby King.

bin it

[LTF85199]

you can still rewind it and bring it back to life

[Stylensky]

You get what you pay for.

na im not blaming the pilot on this one, I have had to many things I had purchased from hobby king turn out to be junk! How about them being always out of stock on those cheap turnigy radios!

As for timing of the ESC, no where in the video does he show what ESC he is using so how the hell would anyone know if even the ESC he was using had a timing setting, could have been one of those cheap 30 amp ESC that you cant program. And timing problem will fry the ESC before the motor anyway.

I think everybody said it, it's operators fault !

[cod4madass]

your timing was wrong without a doubt you bought 2 motors and smoked of them cus of a silly amatuer mistake.

[C0ldFart]

I've just found out that electronics is running on smoke. sooo, when the smoke get's out it stops working :-|

I had a Turnigy motor fail on my E-Flight Eratix plane. Bought two motors and the other worked OK but I am using an E-Flite 32 instead if the Turnigy. No more large Turnigy motors for me. Too much of a risk. Their motors are OK for small foam planes only. Bad customer service when I tried to return the motor too. Just my opinion.

[mysticsailor1983]

the answer is simple , GOD did it , if you dont repent your sins , all your motors will fail like this .......................NOT

[SomeUselessGeek]

Back to the bench. Did you have the timing of the ESC set right? Are you sure you didn't have a broken phase problem (broken or marginal wire)?

[therealheavyj]

@SomeUselessGeek - musta been timing - not a physical problem since 2 different motors failed the same way. But thats ok - I'm way past this now and lovin' the Turnigy Aerodrive stuff...

[brushless55]

Possibly the wrong timing on the esc.

ourtunners need correct timing

[peterm8133]

if you are putting too much current through it, it will do that i tried to put a motor in a boat and it did that even out of water

[bestamerica]

maybe too tight or wrong backforward or twister wires

[knglaser]

A possible mode of failure;

Flying with a too big prop, causing a higher current than the motor could handle. Just enough to make it survive a couple of flights before the enameling on the wire to be destroyed and later on get shorted or burnt clean off.

With only 2 phases left it's unable to start spinning, or get the timing going...

[therealheavyj]

in retrospect and after having owned and flown now probably 15 turnigy motors in the past year id would say that you are correct. The only 2 turnigy motors to fail like this both failed the same way. had to be just overpropped enuf to cook. I seem to recall reading somewhere that it was ok to use 10x4.7 props - but on review i dont see that now. oh well. I'm a happy turnigy customer otherwise.

[daverose69]

This is what happened. You made a mistake soldering on the high amp tube connectors, so you cut the leads a bit shorter and resoldered the connectors. What you failed to do is carefully strip off the insulating varnish from each of the three motor leads. Each one of the three leads has six tiny thin wires going to the armature. Each little fine wire lead must be carefully scraped and sanded to the copper, then twisted again before soldering. Use flux, and a 40 watt iron.

[ChickenHawk110]

Other posters have commented this too.

The way the motor is twitching back and forth, the answer is with your ESC or the ESC leads.

Thats the behavior when one of your ESC leads is not connected or your timing is incorrect.

So,

1: The two motors MAY have been bad motors, the windings burnt out.

2: The soldering was poor which made an open circuit, the windings burnt out.

3: The timing on the ESC was set incorrectly for that motor, the windings burnt out.

But I trust you know this, right?

[therealheavyj]

The motor was twitching after i smoked it - which was after probably 10 flights (on each motor). I suppose it's plausible that the timing was close enough to get it to fly in the first place but off enough that it caused the damage.

I've moved on to the Turnigy Aerodrive - so far so good - these are holding up very well so far...

[therealheavyj]

I had 2 exactly identical motors I bought at the same time that failed in this manner. It would only work (without squealing) in high timing (as I recall).

Having great results with the replacement - turnigy aerodrive c3536-1100 - seems to be a lot higher quality motor for not a lot more money... I own about 2 dozen HK motors. This C35-30 was what i thought gonna be my first non trash motor - buts its been the only one to smoke on me - twice...

[calmatosport]

Yep, this is probably your fault.

Incorrect soldering or bad contact between connectors, or you have a severe timing issue.

Does the esc work on none TGY motors?

[garfield1971]

I have 6 different Turnigy motor, all from Hobby King (Hobby City).

Very good quality motors in use for over 2 years.

Looks more like you use wrong timing on your ESC. (or other wrong settings)
