Smoking a Turnigy C35-30 - 1400kv Bell Motor

I bought 2 of these motors from Hobby King and both of them smoked. Look here in HD glory as I smoked my last one of these. Very unimpressed with these motors I must say. 0 for 2.

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...

[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.

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...

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.

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.

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