Futaba T7c Channel Assignments

Description

Futaba 7CA FASST 7-Channel Computer System 2.4 GHz with the R617FS FASST 7-Channel receiver and NO servos. Choose the 7C instead of a standard 6-channel system to experience the confidence that comes standard with FASST technology. Simply rotate and press the jog dial to navigate 7C programming with ease. Basic menus help minimize setup time and advanced menus help fine-tune performance. This is the airplane version which will default to airplane settings when powered up and has a ratcheted throttle stick.

Futaba 7CA FASST 7-Channel Computer System Features:

  • Futaba’s FASST (Futaba Advanced Spread Spectrum Technology) shifts very quickly, virtually eliminating signal conflicts and interruptions — unlike other 2.4GHz systems that only stay on one or two frequencies.
  • Dual antenna diversity enables FASST system to automatically and seamlessly select the best reception between the two antennas built into the receiver, ensuring the craft stays under constant control of transmitter regardless of altitude.
  • Newly designed Dial-N-Key jog dial with joy stick button allows cursor movement in four directions for very user-friendly navigation through menu and programming
  • 10 model memory

I did not find the answer to my question here. How do I get further assistance?


How does a trainer system work?

A trainer system is a special cord which connects 2 compatible radios together, with the experienced pilot having the ability to hold a switch or button which then lets the student take control. When the student gets in trouble or has had enough, the instructor lets go of the switch and has immediate control of the aircraft. Using this training approach, thousands of pilots have learned to fly with minimal or no crash damage to their trainer models.


What is a "buddy box" or "trainer box"?

A trainer box is the basics of an r/c radio but without any of the transmission components (crystal, antenna, etc). It is used JUST for training purposes. It is a less expensive way for a beginner to get a "radio" to use for his student training.


Do I have to use a buddy box?

No, you can use any other radio which is compatible. For example, a Futaba 9Z can be a master OR a student in learning to fly. A 4VF could be the master with another 4VF, or a 6X, 8U, 9C, or even a 9Z as the student radio.


What about the frequency or channel of the student radio?

The student radio's switch is never physically turned on, so it is never transmitting, so its frequency does not matter.


Does the student radio have to be the same modulation as the master?

For ALL Futaba models of radio sold through 2002 EXCEPT the 7U and 6X, the student radio must be PPM (FM) or set to PPM if it is programmable to be used as the student, even if the master is PPM. For the 6X and 7U, these entry level computer radios had a more limited trainer system which required the student radio to also be PCM if the receiver being used was PCM.


What happens if the trainer cord is pulled out while in use?

Be very careful of this, as it can disrupt the ability of the master radio to send signals to the receiver. Always be watchful about the trainer cord.


Why do you list different trainer cords?

In 1991 Futaba changed their trainer cord to one specific for the FM radio models. This is the black cord most Futaba radio pilots will have and be using.

In 2001, Futaba changed the trainer jack used on radios 9C and all later models to a square plug which snaps in place on a lighter, longer cord. This helps minimize accidental unplugs, makes it easier to work with, and is lighter and move mobile for training.

If you have a radio which uses a round plug with 6 pins, this is the 1991-2001 trainer plug; FUTM4410, M-TC-FM, is the trainer cord which connects 2 of this plug.

If you have a 9C or later radio with the square plug, FUTM4415, MMTC, is the cord which connects 2 radios with this plug.

If you have one of the FM plugs and one of the 9C plugs, then you need FUTM4420, MDTC, to connect these two radios.

If your radio is AM, or pre-1991, it MAY be able to use the FUTM4400, M-TC-AM gray trainer cord which plugs into a 5-pin jack. Unfortunately, we do not have a chart of all the 10+ year old radios' jack types and cannot tell you which cord your radio may need. Please try looking in the old manuals available at: /downloads/manuals.html


Can I use a different brand radio as the student with my Futaba?

We do not recommend or support using other brands of radios as a trainer with your Futaba equipment. If another brand lists Futaba as compatible, be sure to follow all of their instructions and recommendations.


Does the student radio need to be on or off?

The student radio's power switch must ALWAYS be off. Computer radios will be powered up through the trainer cord, and use the student radio's power to operate its programming, but do not transmit.


What's the proper sequence to setting up to train?
  1. Trim the model with the master radio.
  2. With the master radio on, plug the cord into the master.
  3. With the student radio off, plug the cord into the student radio.
  4. Flipping back and forth with the trainer switch, be sure the student radio moves the servos the proper direction and amount of travel. Test all desired functions thoroughly prior to flight.
  5. Confirming the student radio is OFF, and all functions work properly, you are ready to fly!
