This isn't an X6, but the original s107. Sorry, mate. Hopefully somebody finds the wiring diagram you need. Hang in there!!!

Regarding replacement motors.

Is this a Syma X6?  If it is, the replacement motors are indeed A and B. These are for the LATER/LATEST control board.

Take a pic of the PCB, shrink it down and load it.  I am trying to upgrade the Control Board, and use the A and B Motor units.

No question as to Red/Blue.  Those are the rear of the four.  I'm trying to find out which Red/Black goes to which front of the four, since those control left/right turn.

You may have to do it like I did, and put it into Word or Wordpad, then save it as an *.rtf.

I believe JamDJ popped it up in one of his posts. (That or another Admin!).

I can't keep track with whom is doing what!

Regards, Bob, Robert, or Sarge

Well, what I can say is that if it's a clone, I'd rather not worry about which one is which, because you have to replace both or neither. My first heli was a clone, but it had its motors replaced before I got it from Amazon. I'll say right now that it was the best of my early helis until a friend bashed the back end off of my dorm room wall and busted the leads to the tail motor. Now that I'm getting back into these things, I think I'll actually get around to fixing that, if the battery didn't go dead dead.


But, if you replace one motor on your fake, the other will not have the same speed, and will fail on you shortly anyway. They have very cheap plastic brush holders, which get hot, and when you stop flying suddenly, the plastic warps, knocking the brushes out of whack and killing the motor. I would just order a new set of motors, swap them out and have basically a brand new heli for not quite half the cost. (Well, new except the battery)


Good luck!

I was shopping online for a replacement motor and ran into an unexpected question: Motor A vs Motor B

Is A the one to the front? (spitball wild guess)


I have a clone with a blown motor. Without cranking the bird up I am not sure which but I believe it's the rear mounted one.

I have two clones I ordered off ebay.

The red one (my original of the pair) is still going strong.   However, -

the second (yellow this time) was often glitchy in answering the controller (or acting despite the controller). Gratefully, a motor died and I haven't had to struggle with it. Now I've read that the motor failure is common and replacement very feasible, so I'm gonna press on with it.
