OMFG. You think I care whether or not you'd hire me? Besides you couldn't afford my rate.

In Align's defense can you imagine what a Walkera forum would like?

This is COMPLETE BULL!
Sheesh...... someone with the opinion of a doofus who obviously has other problems yet blames it on the 430L. Dude... do you have any idea how many are running that motor just fine? Including me?


I will agree. I have seen many more with no failures than with failures. My 430L (silver can) in my son's heli runs flawless and has just as good power as the 80 dollar motor in mine. There is something else wrong here. I also use the Align 35BL ESC on this combo. A Speckrum TX and RX.

What you don't see in this thread are the vast majority that don't have a problem, as most complain but don't post a praise.

I've never taken the time to calculate how much $$$ it cost to turn my 35 into a decent helicopter. There's not a single Walkera part left on it - I replaced the last part - a cheap plastic boom holder about a month ago).

Someone needs to bump the "Official Align Rant" thread. It has apparently fallen off the main page again. I do believe crappy second rate align motors is captured there.

To the OP, I run a Himax 2815-3000 (its basically the same as an AXI 15-16-3 or is it 16-15-3 -- can't recall) and allows me to run with a nice HS of approximately 2,500 rpm. Its what I decided to go with after my Align motor went the way of the dodo bird.

After looking at your gallery you have an OLD gray V2! So how do you know so much about the Trex SE to even try to tell me I am a know it all


Were we talking about an SE? I thought we were talking about motors. Besides, If you look at my "OLD gray V2" you'll see that it's pretty much an HDE SE.

WTF is your problem? You see the ignore option next to my name? I implore you to use it. You've got a serious character flaw going on there man. Did Mommy not hug and kiss you enough?

Finless,

Can you read, or are you just being an A$$!

In a previous post, I said that I recieved all but one of the motors for diagnosis AFTER they were bad (I performed a post-mortem on them).

The Align motors are build marginal. This IS a known fact!

Align is not the only company with motor issues, but they ARE the only company that build consistantly marginal components!

The design of the Trex is a decent machine. If the parts were higher quality, most of us wouldn't have to spend money on upgrades. The common phrase is wait until something fails before you upgrade it ..... this says that MOST of the machine WILL fail.

These failures are NOT due to design, but are due to the way that Align cuts corners in order to bring a product to market at a low price, but still make a good profit. I think taht most of us here WOULD pay more if the quality was there!

As far as this man's issues, he should replace both the ESC and motor. If the motor is turning slowly, and the "smoke" did escape, either one can be bad, but the problem is that which ever is left IS SERIOUSLY DEGRADED!

The ESC uses MOSFETS to supply the power pulses to the motor. When MOSFETS are stressed, they degrade. Whenever a motor gets hot enough to smoke, IT IS SHORTED (Maybe not a molten mass of what used to be wire, but shorted all the same)!

Francois,

PM me with your address and TELE, and I will send you a spare motor that I have. Noth that this NOT an Align motor !

I didn't say that a fault in the ESC fried the motor. What I said is that whenever the motor fries, the MOSFETS in the ESC become stressed due to the large current demands when the motor "goes-up-in-flames". While the ESC may still operate, it is NOT a good idea to keep on using it unless the ESC's rating FAR EXCEED the batteries possible short circuit rating (because that is the amount of current that the ESC WILL see during the instant of destruction).

Whenever a brushless motor stalls, enourmous amounts of current are drawn from the controller. The way that current is drawn by a brushless system is similar to the way that current is drawn through a series wound motor (let's simply remove the sequencer from the brushless equation to make thing easier). When either of these motors stall, there is NOTHING to prevent the motor from drawing as much current as is theoretically possible from the power source. In the case of the brushless motor, the limiting factor is the ESC and the BATTERY.

Better to be safe and replace the motor and ESC than to take a chance that one of them "survived" the abuse and will continue to perform as though nothing happened (Neither component is unscathed by the experience, and only an idiot would think so).


MOTOR 101
If you use the wrong timimg on a motor, you are INTENTIONALLY degrading the MOSFETS in the ESC. Brushless motors use the INSTANT of static pole incidence as the timing reference. Low timing releases power from the windings slightly before the instant of incidence between the static field and the windings. When the timing is set to Mid, the power is released from the windings just-as the moment of incidence occurs. This results in a greater moment of attraction between the poles, but also, there is also produced a counter-EMF pulse from the windings as the windings pass over the static field. Since the pulse is removed at this specific instant, the counter EMF pulse is amplified by the inductive nature of the windings. When High timing is used, the power is released form the windings Just-After the moment of incidence. This results in a MUCH-LARGER counter-EMF pulse being generated by the windings as the motor passes the moment of incidence.

hey guys

not to be an ass or nothing and mind my spelling but i been reading alot of this post and follow finless post for some time now and i got to say man you really got an isue with how you come on to other fellow members
i see you made videos (i seen a few) and they are good but after you started to make this videos you act like a dam movie star and a know it all, and you can be mean to people just trying to help other pleople out, some times your way of seing things dont have to be perfect but is how you see them and in this matter is how we learn, i know that the guy that started this tread had to be thinking what the F is going on not only this tread got highjack for personal ego and fighting who is right and who is not but getting to thecnical for this guy to understand what is going on just give the guy some advice on how to take on this problem and finless the dont be such an ass and think that your opinion is the only one that counts
once again mind my spelling (my spanglish is getting worst)
and this was only my 2cents
cheers

Poor Francois, the man just wanted some help.
My experience has been very good with the 430L. I expect to get what I pay for. I did the finless mod with the endbells, works great. I did however, notice that the enamel on the windings didn't seem the greatest. I just made a note to be cautious with the motor. So far every thing is lukewarm when I land. That is w/ a 13t pinion and 315 woodies, tt curve 100 95 100 +- 9 deg pitch. I'm no pro, just flips, rolls, loops, and inverted.

Francois, I hope you find a suitable motor. IMO it is kinda a gamble if look at the statistics. The price makes it worth it for me however. I just wish the motor had some more margin.

Hey all, can't we all just get along? If I hated something soooo bad and it always gave me trouble, I'd leave the broad er, heli.

Francois:

I would try sending the motor and ESC to Align and have them check it out. Maybe they will replace it for you. If the radio is glitching, take some advice from Finless and check it, it could be a contributing problem, and if it is, getting a new Align motor and ESC will lead to another similar failure. Another brand _might_ hold up better, but if the underlying problem is not solved, it's just a matter of time. If Align replaces them for you, Hurrah, otherwise, I personally would make another choice. But I'm a relative Noob to electric helis and readily admit it.

I'd have a look at a Castle Creations 35 and a JGF 450TH. Excellent combo, IMHO. I use the DX6 Spektrum package and have had NO Glitches. Very happy with the combo. Just wish the DX6 had a few more curve options, but it's working fine for me as a newbie.

Bob is just a tad opinionated, but very helpful, and a nice guy, always willing to help. Can't say enough. I followed his videos in my setup, and my heli works great. Hard to argue with success.

Oh, and none of you guys try doing any 3D moves with your Toyotas. They WILL void your warranty for that. I have had quite a few Toyotas and they are very good built and very good service. The GMs have been marginal. But that's another forum.



Cheers!

finless i agree with you

but that is why we got this forum we get some bad advice and some good one too, your advice are good the only problem is that we need to get some points acrosse more nicely and people will be like hmmmm finless is right, instead of people fighting with you because they felt threated by some coments you make just my 2 cents cheers

Under all the rhetoric in these threads, there must be some grains of wisdom somewhere. However, I hear the bell ringing, time to come in off the playground boys!

For the benefit of everybody.

I got a new motor from Align today, install it and fly 3 full lipos....and guess what? perfect fly. With the new one I realise now that the old one had something wrong since the begening. At every flight I thought the wind (15-25 mph)was doing strange thing to the bird , it use to drop 6-7 feet and climb back as I describe in my first post. But today strong winds 25 mph and never drop, very stable and a lot of fun.
