I have a 2.4 Futaba transmitter and I installed a 617 receiver in both of them. I have everything setup for both planes in my transmitter, but this morning I had both planes turned on and the servos for both planes moved together. Is this normal? They did move in the correct direction for whichever plane I had programed in at the time, but I was shocked to see the servos moving on both planes.

Did you rebind? (link)
Bind each receiver at a time be sure that the other receiver is turned off.
No it is not a normal situation, could be a real issue, but you need to bind firstly.

Link Procedure
Each transmitter has an individually assigned, unique ID code. In order to start operation, the receiver must be linked with
the ID code of the transmitter with which it is being paired. Once the link is made, the ID code is stored in the receiver and no
further linking is necessary unless the receiver is to be used with another transmitter. (For T/R set, the link is already done at
factory. When you purchased another R606FS, this procedure is necessary; otherwise the receiver will not work.
1. Place the transmitter and the receiver close to each other within one (1) meter
2. Turn on the transmitter.
3. Check the LED that is placed on the back side of the transmitter to see if the RF signal is active. When the green LED is ON
solid, the RF signal is being sent.
4. Turn on the receiver.
5. Press down the "ID SET" switch for more than one second, and release the switch. The receiver starts the linking operation.
6. When the linking is complete, the LED in the receiver will change to solid green. Please confirm that the servos will now
operate by your transmitter. Please refer to the table below for the LED status of the receiver's condition.
No signal reception Red : On
Receiving signals Green: On
Receiving signals, but ID is unmatched. Green: Blink
Unrecoverable failure (EEPROM, etc.) Red and Green
turn on alternately.

Yes, this is normal and nothing to worry about. If both receivers were bound to that transmitter, then both of them can be controlled AT THE SAME time by that transmitter, even if they were set up on different planes. There is on one radio on the market that will differentiate between which model you have selected, and it's not Futaba (JR/Spektrum to be exact).

This is nothing to worry about. You just need to ensure you have the correct model selected before you fly (something that pilots have had to do since computer radios hit the market)

Like Ken said, as long as they are bound to the same transmitter and they have power, they will work. you could have 1000 recievers bound to that trans and they will all work. now if it is making a NON bound reciever work, then you have a problem.

Ken:
I was wrong stating that it was an issue, I tought that all receivers could work with some difference as the manual state, but I do not own that system then I posted what the manual says, sorry for any missunderstanding.

Alfredo,
not a big deal. A lot of people think that because the JR/Spektrum has the ModelMatch all 2.4 radios have it. it's a patented item that JR/Spektrum has. We probably won't see it from anybody until the patent runs out!!

Ken

Thanks... If someone has the same transmitter that I have at the field, will that interfere with my plane?

No. The receivers will respond only to the transmitter that they are bound to. Another transmitter can be turned on and your receiver will no respond to it.

Ken

With all 2.4 systems, the reciever will only respond to the transmitter that it's bound to.

Whats unique with Spektrum (and this doesn't apply to the modules, just the native system) is the reciever takes that one step farther and only responds to the correct transmitter AND correct model memory selection.


Its the same way garage door openers and remote locks on cars have been working for years, they all use the same frequency band but you make the door opener (or car) memorize the code from the controller so it only responds to that one.

Hello and thanks in advance for the help.

I have a Futaba 4pk for my cars. I successfully installed the 4 channel reciever in my OFNA car and it linked and works fine.

Then I tried to put the 3 channel reciever in my Kyosho gt2. I cannot get it to link. The batteries are fine.

I turn on the transmitter and then the reciever. I push the little button andit blinks red, then goes solid red. It will not go to green.

Why the blinking red and what possible reasons why it won't link. Everything is brand new.


Thanks

Jim

Jim, if you do not get the answer in this thread:
Place a New Post in the 'Futaba Radios Direct Suppoirt Forum' http://www.rcuniverse.com/forum/tt.asp?forumid=125 describing the issue. Bax or Krysta should be able to help.

I think (but not sure) that the 3 channel Futaba systems use a slightly different technology than the other Futaba systems. Get a definite answer in the Futaba forum.

Did some research. http://2.4gigahertz.com/modules/modules-receivers.html Looks like it may work if you use "C1 Mode" which selected "on screen" according to the notes. Check in your manual for more details. http://manuals.hobbico.com/fut/4pk-2_4ghz-manual.pdf
