I had an airtronics tx/rx/servos, but now the radio is junk. I am going to put the rx and servos in a different plane. What tx's are compatible to use with this rx?

I also have a new futaba radio which has model memory(rx in a different plane)but I dont know if these will work together. Is it as simple as just getting a new crystal for the rx? do you have to get a certain brand of crystal to use with certain rx's/tx's?

thanks

The servos will work with any radio. However, the Airtronics receiver is not going to work with a Futaba Transmitter.

Thats correct the Futaba and Airtronics Rx will not be compatable. You can use any JR FM tx or any Tx that is shift selectable such as Hitec Prism 7X, Optic 6, Eclipse 7 or the new Corona with that Rx. Making the assumption you are talking about an Airtronics FM Rx and of course not an Airtronics AM Rx.

John

okay so airtronics servos dont have plugs that are wired the exact opposite of futaba?</p>

Only the older Airtronics servos do. But all Airtronics servos with blue plugs on them are wired the same as all other major brands on the market today.

Ken

I think you are confusing two separate compatability issues. First is the modulation shift, for a Tx and a Rx to function together they must be of the same shift (positive or negative) or either the Tx or the Rx must be shift selectable to match the other.

The Servo plugs are a different issue altogether. If your Airtronics servos have black plastic plugs with three splines then no they are not compatable with any other brand Rx or the new Airtronics Rx's. If your servos have blue plastic plug (this is the Airtronics 'Z' plug) then yes they are compatable with all the other Rx brands.

All of this would be a whole lot easier if you would just say what color your servo plugs are.


John

sorry, they are blue plugs. Does this mean they would be compatible with a futaba rx? also how do you know what the modulation shift is for the brand/part number you have?

thanks

blue plugs are ok...then..if is not..you will see smoke coming from the serve after you connected lol.

Good - Blue plugs that means you have the current airtronics plugs and they are compatable with all the other top four Rx's however thats only the plug issue. Agine that has nothing to do modulation shift.

How do know if a certain Tx or Rx will be compatable. The answer is simple you ask but an answer is impossible if you do not post the exact brand and model of both the Rx and the Tx you wish to try.

By factory default Hitec and Futaba use negative shift, JR and Airtronics use positive shift Howeverthere are many various brands and models of Tx as there are Rx's that are -Selectable shiftor-Auto shift Thats makes litterally hundreds of possible combinations that may OR may not work. Its like pulling teeth you need to state the exact make and model of both the Tx and rx you want to use.

Things such as this make piecing a system together from freebies and the bay a nightmare and unless you know exactly what you are doing folks who insist on 'Saving money' like this usually end up spending considerably more and end up with old setups usually not nearly as capable if they had bought a new entry level system.

zehms82: I am just going to add this in support of what JohnBuckner has said: Yes, the Airtronics Z servos (the blue connector type servos) are all compatible with most of the receivers on the market today, including most of the 2.4 GHz receivers. But, I would be careful when using various types of servos together, meaning mix-and-match.

For clarification, you can use two, say Airtronics 94102Z servos on a dual aileron setup, one on each side, but I would avoid using a Futaba and an Airtronics (for instance), or JR and Hitec on the dual aileron setup. The speed and throw percentages may be different. I don't know that they are different, but it's a pretty good bet that they won't be exactly the same, which can be problematic.

You CAN, for instance, use Airtronics on the Ailerons, JR on the throttle, Hitec on the elevator, or Futaba on the elevator (all examples of mix-and-match example scheme) or any combination you wish or have on hand, but don't mix them on the same control.

I don't know your level so you may not know that some planes have two servos on the wings, one per side for the ailerons, or flaps, or may have two for the elevator, one per side, and so on, that may be more advanced than you are up to at this point, but it's just an example of what you can do and should not do with various servo types.

But, the bottom line is that most of the major manufacturer's servos are cross compatible with other systems. You may have to reverse the direction, but you will see that right away and take care of that with the transmitter setup.

Hey CG You are a busy little beaver this morning with all those post on different subjects. I did at your advice buy some Airtronics servos and they work great. Have them on the wing of my Big Bingo. There I didn't hi-jack the thread.
