detail photo brushless upgrade guide

[coredump]

I change my esc to the walkera 10a pull from a 4#3b bl main. It does not need a converter!

I like it better than xp7a + aeo converter. The old setup throttle max out at 80%. With walkera ESC, I have throttle response up to 100%. I also feel that I got more head speed and power from walkera esc. Which is surprising, given m5 should draw about 3A average.
(3 minutes fly time, I charge back 150 mah, so 150mAh x (60 min/3min) = 3000 mAh).

My guess is that the FET in walkera is better. It is cleaner too. I think that is the better price performance ratio. You save on the converter.

Where can you get that Walkera 10amp? Is there a specific part number? That looks way easier to wire up anything else out there for sure. Good stuff.

[coredump]

It is the stock ESC from my 2 years old walkera 4#3b brushless.

Pay attention to what Dylan said about the different version of the
walkera ESC.

I have the main ESC and it works for V2.
I know for sure that ESC does not work for V1 board.
It might need the negative PWM version, the tail ESC as Dylan
put it.

There is an ebay link in the walkera esc thread, steal it here:

maybe it has something to do with the rev of the V1 board because i know for sure it works with my V1 board and can prove it quite easily hmmm.

edit:

maybe not that easily because the video camera on my phone can't focus on the writing on the board anyways its a V3.9 and the ESC is a L version, the very same version that i used on my V2.

[coredump]

I try this setup on V1 3.9 and it does not work for me. My ESC is the main brushless
ESC. It is also possible your wakera ESC version is newer than mine. My walkera
ESC is 2 years old. Your walkera ESC will most likely have newer firmware.

Edit:

your are using the tail ESC on V1. That is the known working setup.
My ESC is for main motor, so it doesn't work on V1, it works on V2 though.
Check out Dylan's post in the previous link. It all match what he said pretty
well so far.

[craig303uk]

i don't get it unless mine has newer firmware then?

it was bought only a month or so ago, it is a L version and worked on my V1 and V2 3in1's, wierd lol

[coredump]

You are lucky then. I wish mine works on the V1 too so I don't have to get another one.

Positive or negative PWM, it is all software any way. I am not surprise the new
firmware can detect and auto fit.

[craig303uk]

its about the only luck i've had since getting the damn thing ach a bit suckie it hasn't worked for u though.

[coredump]

Not work for my V1. But I can always use it for the V2 as main ESC.
That ESC is collecting dust any way, it is like the sudden new found extra
boast for the M5. I upgrade to the double brushless on walkera and
never use the stock ESC again.

[Supaplums]

Thank you very much for the great photos! I'm doing this on a v1 board. I have the AEO converter, an HP05 motor, and the ESC I'm not too sure about? I got it used and it's supposed to be a 10 amp. Are there a lot of different 10 amp ESCs? Wonder which one it is? I'm guessing the wiring will be the same right?

[coredump]

Now I have v1 board as spare. I
attach picture for wiring the v1 board.
The rest of the upgrade is very similar.

Do you have picture of your esc?

[new bee]

Thanks for the write up. I had picked up a v2 board before then changed my mind after reading all the mess some were having. Since i have sold both of my c05's and i have this new info. I picked up another v2 board so i can give this another shot. It should be hear later this week.

[coredump]

Glad that it helps. Let us know how is your walkera ESC works for you.

It would be interesting to know which MCU there is on the Walkera ESC you are using. See this post regarding the Atmega chip.

https://www.helifreak.com/showpost.p...7&postcount=28

[craig303uk]

they are both Atmega8's

16Au - 0830G

16Au - 0852G

[coredump]

Mine is ATmega8 as well.

[craig303uk]

can u make out the number below? it would be interesting to know.

thx

[coredump]

err, I try to look up the number. But the ESC is solder and I make the
wire as short as possible, so it is very solid on the main board.
The problem is, I need to unsolder to see it. This is my worker
horse heli now, a little bit reluctant to mess with it. Maybe I will do it
when I finish converting my V1 into brushless.

[craig303uk]

its okies would need the number off the chip there are a few of them from the looks of it, i was just thinking yours might have started with an 06.

i have another 3 non working L's 1 of them starts with an 06 and the other 2 08, shame i can't test the older 08's because they have a higher number than one of the one's i recently purchased

0620G, 0832G, 0843G.

wonder if this would be related to the firmware or whatever and why the ESC's worked out for me.

sorry just blabbing now

[coredump]

Ok I do it for you. I unmount the motor . It is 16au 0843G.
