Hi Maytech great to have you here.

I wrote a support email about 4 weeks ago and never got a answer. It would be great to get a comment what might have gone wrong. Thanks Boris

i am having big problems with the Maytech Opto 35A V2.
I have set them up to my Hexa multirotor which was running fine with turnigy plush 40A before.
No matter which settings I am using on my AXi 2820/14 motors which are expensive and high quality motors, the motors will not start up spinning without problems.


Please see the video : http://vimeo.com/36179776


Eventually the first startup already resulted in a damage of my motors since i got the smell of something burned from them. Since i fly expensive camera equipment those motors are not reliable for me anymore.
Could you please forward this email to support or development so i can get some clearance on what went wrong !.


Initial config for the ESCs. No matter which setting I choose though the startup problem stays, changed timing to motors accordingly, start up strength etc. The only thing that reduced the issue is putting governor mode in soft start 1 or 2: But the problem it still visible at the beginning.


Brake: offBat Type: NICDCutt off: No protectionMotor timing: AutoSbec: not installed since optoGovernor mode: RPM OffRotation: as neededStart up Strenght 30%Low Voltage Cut off Typee: Reduce Power

Hi Boris,

Thanks very much for trying our ESCs.[
It is so regretful we did not get your former email about the problem you meet.
We will download the video and check it. I believe our sales staff who once took care of your request will email you the feedback.

Thank you.

Hi Guys,

just wanted to report how my situation was resolved concerning my Maytech V2 Axi 2820.

The answer was that Maytech V2 are not compatible to AXI Motors. So if you guys order V2 make sure they guarantee that the V2 work with your motors.. I have a loss of about 700 to 800 Euros including ESCs not usable for me and the six smoked up Axis, that will certainly will not be put on an AP plattform anymore.

Boris

"This is because the motor is not well compatible with our MT V2 ESCs. Our MT V1 ESCs work well with AXI motors.
In order to be compatible with most motors in the market, we cannot adjust the software to meet specific motor specs. "

Man that sucks! It would be nice if Maytech would have alerted everyone with that incompatibility. What other motors are they incompatible with?

Hi Man, we tested AXI 2808, 2814, 2826 motors this week, with our V2 ESCs, they were working well.
We will check what the problem working with 2820 motors, although we also have customers who use V2 ESCs and 2820 MOTORS and they all work well.
Last, our V1 ESCs are good compatible with the multi-rotors.
Pls adjust the ESCs settings correctly according to the controller and the motors you use.

About Boris burnt motors, I am sorry to hear this. What propeller size you use and the timing mode you set for the motors. If so many motors you burnt, It is better you should also contact the motor supplier why it happened so much.

Which statement is to belive ?

@ maytech, Boris is no Newbie to Multirotor technic, so I think you should look for the problem at your ESCs and not the AXIs​

Hi Man :) Hi Maytech

All i am getting at is that this was the outcome of me hooking up the maytech 35 A opto V2 to any of my six axis,


In the process or at the first startup and 2 of the 6 axis produced smoke and all others reminded me that summer is coming since they make me long for a BBQ.

I tried all the different settings, repeating myself the only thing what made it better but didn't get rid of the problem was setting governor mode to soft start 1 or soft start 2.

Before you ask yes i tried all different timing settings every possible setting the ESC offers, but dedicate to one motor since i didn't want to squeeze the last life out of those that might still have some substance left.

What i don't understand is you calling out axis are not compatible than pulling back from the statement and saying yes its work. Shouldn't you guys know from beginning what works what not, considering that there is not such a huge difference when it comes to the motors used for multi-rotors ?

And than take this as a fair approach from my side not mentioning any names and pointing the finger directly, but ask around in support if I am the only one having motors smoke up using your V2 ESCs. Either you know already or you will be surprised !

It would also we very interesting to get an explanation why this motors start up problem always happens at the second startup try in the same rhythm on going? For me it is obvious that its am FW issue that you might have resolved in the meantime. !

What i heard both Maytech and HK (as many else) hardware manufactured by this company: http://ztwoem.en.ec21.com/ Please correct if i'm wrong. I have now 6x V1 and 6X V2 maytechs. I have startup issues too with V2, a bit similar but not as bad as Boris had. Don't want to wait them to start smoking, and this is combo with QC3328 motors. My motors get also very hot quickly when dodgy startups but this happens more randomly than Boris had. But this is only startups without props, when props are on it seems to help but...

V1:s are starting fine and my setup was flying great with them but i can't trust them at the moment because likely one of them failed in flight last week and it was very very close i crashed cinestar setup with dslr on. Hope i didn't screw my motors with V2:s after testing them again after V1 failure.

Kari



Just a FYI.

I have removed the heatshrink of a Maytech V1 esc and I find the hardware identical to my other Esc...
http://www.hobbyking.com/hobbyking/...0A_BlueSeries_Brushless_Speed_Controller.html

As to why a V2 destroyed a set of very expensive motors is entirely the ESC' fault. Under no circumastances even under wrong settings can a healthy esc destroy a motor.

EKKK!
This al sounds VERY disturbing. I have been using the Maytech 20 amp version 1 ( I think) on my FW450 with TorxPower motors NO PROBS what so ever. Is it just the V2s that have the issues?

Japp as far as I have heard and seen the probs are only with the V2. Most people are happy with the V1 version with no major problem as far as i know.

Hi Lars,

Thanks very much for your comment.

Boris said he used AXI2820/14 motors, it is not the AXI 2808, 2814, 2826 we once tested before. So we replied to him it is may be due to the compatiblity problem of the V2 ESCs and the motors he used.
AXI2820/14 current capacity is 36A/60s, Boris used our 35A-V2 ESC, we need to confirm with Boris which propellers he used.

THE MAIL FROM YOUR SUPPORT TO BORIS: "This is because the motor is not well compatible with our MT V2 ESCs. Our MT V1 ESCs work well with AXI motors.
