Does it work with the mcpx brushless from hk?? i mean does it work/fit for tail and main or how i install the 2 brushless motors any tutorial or pics or an instruction avabial???? Would be nice to get some jnformations abut how to use the motors and whag you need...

As per a few other folks here, I too am having timing issues. I have mine hooked the "the steve" converter and the CO5 brushless motor in my mCPx. The only way I can get the motor to start running is to turn it by hand and then it runs fine until I s***l down to an off position. Are there any ESC programming procedures out there for this little ESC?
 Rototiller 49 points
I have not seen anything for programing but mine did the same thing till I soldered the motor right to the speedo. Starts every time now. HTH
 john 47 points
Great Tip - Will give it a try! Thanks!!
 john 47 points
Well everyone, that did the trick! Soldering the three C05M motor leads right to the ESC board bypassing the three prong plug solved the funny timing issues that would prevent the motor from starting up. Thanks again to Rototiller for that great tip... MCPX's need a brushless upgrade to get the most out of them and this little 7A brushless ESC works fine in conjunction with the C05M motor.

How do we program the esc?, and is there a compatible programming card?
Is there a manual?
Michael  5 points - 7/14/2012
 
Does anybody know how to program this esc with the transmitter? thanks in advance

do any body no if this esc has a bild in converter if not how do you connect a converer to de 7 amp esc. do anybody a diregram.
 Bent 33 points
There is no converter in it..... You need the "double-chanel ultra micro brushless converter".
BEST ANSWER CREDIT AWARDED
 ronald123456789 11 points
Oke thanks bent do you no how to connect this t the converer. So yes is there a digram of it
 Bent 33 points
It is a dual converter, so you have blue and yellow in and out. (Use only the yellow or blue = one channal converter)
There are arrows indicating in and out!
Connect yellow "in" to one of the mcpx motor output (signal for brushed motor).
Then conect yellow "out" to signal on ESC (the red one with mcpx looking motorplug).
Red( ) and black(-) to the battery.
 ronald123456789 11 points
Oke thanks bent i see it now so you use one channel for de tail en one for de main motor and de 2 small wire's(from the esc)the not use. and for the break you only use the bleu or the yellow wire.
 Bent 33 points
I have uploaded a diagram under "FILES" called: Mcpx connections.
You can connect the converter power to the two thin red/black from the esc, or connect them as i have shown.
 ronald123456789 11 points
oke i see it the foto. very nice i hope i to have the stuff quickly.

do you heve this setup also so yes is is good stuff.and where do you place the converter en esc
gr ronald
 Bent 33 points
Yes i have the 1s 7A ESC, Dual converter, C05m motor. I am not satified with my setup, as it seem that the esc isn´*t timing vel.(can´*t find how to setup esc!)
I have put the converter on the esc, and the esc on the mcpx main board. (Be careful not to short circuit anything!)
 ronald123456789 11 points
oke thanks yes i will put the converter direct on de esc en de esc not on de board i whil thak the power cabels and solder them together. mabby you have a foto from it. if you you can mail it to me trex450*hotmai..nl you no

It's great if it built in converter, but not sure. I'm wait for the answer too.
 Rototiller 49 points
No built in converter. You have to add one. The wire with the connector is for your signal.

is this like micro helis upgrade
 aaron2233 528 points
any body going to answer
 hoggy33 45 points
Not sure about the microheli esc, but this esc is similar to the xp7a you still need a brushed to brushless converter for it to work with the mcpx.

yes aaron you can upgrade the mcpx with this but ur a durp and lol ... come to mine tomoz
 Sejong 1 points
Photo of the esc only the line of the connector to connect to the converter's output ones you find attractive? The remaining two wires connected to the battery and how do you handle?
Norbert1  62 points - 5/27/2012
 
I ordered this esc for my mcpx. Now I connected it to the motor the baterie, the hot motor connector out and plus/minus to the mcpx. Swash and rear prop is running, but no beep or function on the brushless motor. With other ESC motor is beeping and running. Is this esc broken or does it not fit to mcpx? But no beeping or LED at all? No instruction come with the esc.
 Rototiller 49 points
The big red/black wires are your battery input, I solder to the board. The 3 hole connector on the board is for the brushless motor. The wire with the connector on it gets soldered to a convertor. The convertor gets soldered to the board for signal and - for power. The last two wires are and -. Those two along with the singal are what you noramlly plug in to a rx. I just unsolder them to save weight.
 capitansalomon 13 points
Hello, do you know if it's possible with this device and the bl converter upgrade the motor of the N.Eagles ultra micro yak 54? Thanks
 Rototiller 49 points
Sorry I dont know that plane. The convertor just changes the signal from digi to anolog so the speedo can hear it. Other then that this is just a normal speedo. If that plane has a anolog signal then this and a motor will work, no convertor needed.

any diagrams ? especialy for the three lead besides the battery wire ? is it trully esc with a converter ?
Norbert1  62 points - 5/5/2012
 
Is a converter for mcpx needed or is it integrated?
 hotsam 250 points
If this had a converter included, be sure they would have it in the (true enough short) product description. Also they offer the brushless converter as a combo, which wouldn't make any sense if it was included..
 Timm 2 points
But why there is a plug who looks like the Motor connector?
 Norbert1 62 points
Thats the question why I ask, nobody here who has the answer? Next question is: Its called a microheli upgrade - which microheli has a pcm output for brushless? Also as a normal BL ESC is it to expensive. We have to wait for the answer.
 aaron2233 528 points
hello the coverter is very good because it make it brushed to brushless i love it it is the best thing for the mcpx v2
 hotsam 250 points
hi aaaron, are you talking about this product here? do you have it already, and tested it? and it is a converter AND an ESC??
 aaron2233 528 points
yes i do have it and it is very good for what it is
 hotsam 250 points
cool! and it is? a brushed to brushless converter combined w/ a brushless ESC? do you mind expaining how to wire this? Cheers
 aaron2233 528 points
wel the one plug goes two the right side of the main motor then you wire it to the brushless motor then you need a bigger battiery
BEST ANSWER CREDIT AWARDED
 hotsam 250 points
you sure are a man of few words *)! Yes and I'm a BL-conversion dummy: If the plug goes to the motor-output and the 3 jacks on the other side are the A/B/C for the BL-motor, I still don't get what the other 4 wires are for. 2 of them to parallel the Battery, i soppose? and the the 2 thin pos. and neg.?
 aaron2233 528 points
you dont need the two other wires
 Norbert1 62 points
hello maaron2233, are you sure you own the esc and use it on a mcpx? The 2 thin wires must go to mcpx all-in-one electonic. The single pin of the esc goes to the left side of the main motor socket, but dont fit there. Does this esc really work on you mcpx?
 Michael 5 points
the three jacks go to the bl motor, the longest red wire is the motor signal, the two thick red and black wires go parallel to your battery. now the two wires left would be for your receiver. you have three jacks on your receiver, signal and -. if you use it with your mcpx you dont need those two and - wires because your mcpx board is already connected to your battery.
 Michael 5 points
*its signal, plus and minus on the receiver. it deleted the plus sign...
 Norbert1 62 points
Hello Michael, when I right understand, can´*t I plug the ESC direkt to the motor out of the mcpx. I need a converter to translate it to a normal servo signal, like it come from a standart receiver?
 Michael 5 points
i am not sure about the signal yet, gotta test it first. but i wont be able to test it until the end of june. just connect it as described and you will see if it works or not. the wrong signal should not destroy the esc.

1 thumbs up!
Received the item yesterday it is not a plug and play option for the mcpx it still requires a brushed to brushless signal converter. I had a spare 'the Steve' so I wired it up and it works perfectly. Here is how to wire the Steve to the esc. The Steve has four wires red blue yellow white. The white wire is soldered onto the board in place of the red wire with the motor connector on it. The red wire is soldered onto the board in place of the smaller guage red wire. The blue wire is soldered in place of the smaller guage black wire. The yellow wire is then soldered to the resistor point on the back of the board or the positive side of the main motor plug Hope this helps

Speedo works but I have to hand start it. Its paired with the co5xl and the double-channel converter. Once spinning is does great. The single lead with a plug is your signal, the convertor goes there.

Got this into my mcpx just fine with the converter.
Motor stuggles to start even without the rotors connected.
Looks like a timing issue, above 1/4 throttle seems fine.
Would give 5 stars if I could program it.
Yet to fly...

For MCPX users: This ESC can be flashed with the BLHeli code (Atmel/HC5A1SA48V code). You have to disable the transmitter programming feature to fit inside the 4k flash. Also I found the battery voltage sample to be noisy and added a cap on the voltage divider network (could have been fixed in software too). With this code you can connect directly to the main 3-in-1 board without the brushless converter. It also has a governor mode which is a huge improvement. I'm running a HP05S and it works pretty good. I also increased the P gain to 3.0 on the governor PID controller. Attaching a connector for programming does require some soldering skills, and you do need a AVR programmer.

I´m in general happy with all from HK. But this ESC - I don´t know. No instruction - ok, it´s not my first ESC - I´ve also 2 other brands for my MCPX. I plugged the thick red and black wire to baterie, the thin to mcpx. The single plug to the motor out of the mcpx. The rear motor works, swash plays but BL Main no beep, BL ESC no LED ??? With other ESC all fine. Again HK BL-ESC only Motor and baterie - no livesign. Is the ESC dead - or something wrong - I don´t know. The dsicussion tab helps also not, so I will send it back - -sorry .
