After 1991 or so, most of the major brands of servos became compatible with each other. You can use any of
these brands of servos with any brand of receiver. Some brands of servos are really great for a
particular use in a particular plane. There are companies that have servos
available with a choice of connectors. If this is the case, be sure
to request that the servo is equipped with the connector that is
compatible with your receiver.
You can connect Futaba servos with an Airtronics
receiver as long as the Airtronics receiver is designed to accept
the Airtronics Z connector. However, you will have to cut off the
flat polarizing tab that is on one side of the Futaba servo
connector. You can connect Hitec & JR servos to a Futaba receiver
but, be sure to observe the wiring color code when inserting the
servo connector into the Futaba receiver so that you do not insert
it with reverse polarity. For Futaba, Hitec, and JR receivers, the servo, battery
and signal wires are properly oriented. However, the Futaba servo connectors
are physically different because their servo connectors have a
keying tab on the side which prevents the servo connector from being
inserted into their receivers with the wiring polarity reversed. The
other manufacturers' receivers will not accept the Futaba servo
connector as long as the keying tab is present.
reverse the direction of a servo (reversed servo) by swapping (+)
and (-). If you do, you may burn out either the servo or the
receiver or both. It's a lot easier to buy any of the newer
transmitters that have servo reversing built-in.
As of December 1997, Airtronics is now shipping servos with an optional "Z" connector that matches the
connector found on JR Radio and Hitec servos. Be sure to request
that the servo is equipped with the connector that is compatible
with your receiver.
If you have or are considering purchasing Airtronics radio
can read about the
Airtronics 'Z' connector.
I usually cut off
the little side tab on the Futaba connector with an Exacto knife if
I want to use it with a Hitec, JR or Airtronics Z connector
Do not connect an Airtronics servo to any other brand receiver
unless the Airtronics servo uses their newer Z connector! Do not
connect any other brand servo to an Airtronics receiver unless it is
designed to accept their Z connector!
Shown below are the three standard connectors that are used by
Futaba, Hitec and JR. The Airtronics connector shown below is the
connector that was used prior to the introduction of their Z
connector. This connector is not compatible with the other
Manufacturers' receivers nor is it compatible with the newer JR
receivers that are designed to accept their Z connector.
