ok guys I'm buying remy's mx-3 and i was doing some investigating.. airtronics says they use a "z connector" as opposed to a regular servo connector.. i looked at it and seem that the only difference is the red and black wires are switched.. is this the only difference?? so i can rearange the ones on my servos and be ok?? or do i have to buy there little connectors?? i have a hitech servo and a factory ofna one but nether have the blue plug on them.. also is the battery wires switched to or not??

if this has been brought up befor I'm sorry.. i looked in the radio gear section but came up empty.. can someone please instruct me in what to expect on this radio.. also if anyone has some airtronics receivers available that would be great.. cause this radio has 5 model memory so i can get rid of all my radios and just use this one right?? thanks for you time guys!!

I'm not sure what makes a "z" connecter a "z" connector. I have the MX-3 w/ the stock receiver. It came with a couple servo's. As far as I could tell, what makes it a "z" is a little plastic flange part that you can cut off. It's kind of a guide and also makes it harder to plug the servo's in backwards. Unless you have really fat thumbs and smash it in there anyway.

on the websight it looks like the ones with the blue ends have the red and black wires reveresed.. is your receiver blue??

someone please help!!

the airtronics radio I have has the wires in the normal position. but then again mine's the MX-A

Yep, mines blue. I never had to switch any servo wires around or anything. I've used airtronics servo's, hitec servo's and futaba servo's in the airtronics reciever and I never messed with any wires. Just plugged them in.

Here's what I have and the servo's I use:

This receiver: http://www2.towerhobbies.com/cgi-bin/WTI0001P?&I=LX0785**&P=V
These servo's:

Hope this helps you.

I have the MX3-s. Same as MX3 except synth.

Anyhow, I have run every type of Rx and servo off of this, including Airtronics servos with non-Airtronics Rx's. "Z" just means it has the little extra piece on the plug, You cut it off and everything then works as normal. I have never had to change any wiring. Even if it was reversed, (which I have never noticed) your Tx can reverse modes for a servo, so it should make no difference. I do not think polarity can or would be an issue in a servo only because you can run one reversed at will by the settings on the Tx anyhow.

this is why I'm asking.. see the pic of the blue reciever.. its ground then hot then signal then you see the pic of the black reciever its red then ground the signal and they have the connectors that switch it..

olds i looked up your setup and all but the futaba servo say there "z connector" compatable..

man this is confuzing.. i dont wanna burn up my servos.. but i dont wanna do a bunch of work that i dont need to..

I believe it will depend on what receiver you use. Do you know which it's coming with? Once you know the model, you should easily be able to look up the correct pinning. Just verify that with the servos you have. If you need to switch the pins, it's easy to do. No need to buy new servos. Or you could just buy adapters. But switching the polarity is simple and free.

 

[beason]

dunno ill ask.. its like 6 months old so it may be the older black reciever..

 

[Revo Rancher]

Beason, that link confirms what I thought. The important issue is that the signal wire is in the right place. The hot and ground lead might not be important especially considering the MX3 Tx has servo reversing capability for all three channels. I do not think servos "think" in terms of polarity for any other purpose but to reverse their operation. If it did matter, then the Tx would not offer servo reversing features. Reversing of the servos is done on the menu screen, so actual mechanical switch is involved.

However, like Candyman states, it is real easy to switch the pins. Don't waste money on the adapters.

 

[beason]

the radio could just "switch" the signal it sends to the reciever.. and call it servo reversing.. you tell it left it tells it right.. ya know.. dunno ill switch the pins just to be safe.. I'm not even sure which rc to put it on right now.. lol

 

[vbgagnon]

Hook up that junk servo that I sent you. I won't matter if that one burns up. If it works then you should be set. Ofna electronics are futaba based.

 

[beason]

futaba is the only one olds listed that DIDNT clame "z connector" compatability... oh well.. i got a week or so befor having to figure this out.. WE NEED MORE INFO!!!

 

[vbgagnon]

what servo's do you have? I'll get you the info you need. I also need what reciever your getting. (model number)

 

[beason]

ill have to get back with you on that.. dont have the receiver yet and not sure which rc its going in. will be wether hitech 645's or whatever you had on the throttle on the buggy..

 

[Revo Rancher]

These are DC motors. They turn the same either way. I would imagine you might be right that just the "signal" is being changed by the switch, but polarity still should not matter as to the health of the servo. Maybe Plaid, our electrical specialist, can correct us all.

 

[Plaidfish]

Revo you're right....+ & - are not important....the signal wire is the one you want to make sure you aren't applying supply voltage to....on your Rx you have 2 pins that carry the voltage to the motor....the 3rd wire (signal) is a SCR signal.....like an electronic version of a potentiometer.......I do actuator designs for HVAC damper control sometimes and it's just a very large hardwired servo....if you cross the +/- it just reverses the direction of the motor......there might be a small chance that the controller in the servo gets it's power from +/- and it's polarity sensitive but I haven't seen micro controllers that are polarity sensitive anymore in the last 5 years...I can't imagine these servos are using ancient technology....Beason...hook it up and just make sure your signal wire is in th eright slot.....

thanks a bunch fishy.. and everyone else.. you guys are great..
