Dit heb ik nog gevonden op de faq-server van de Amerikaanse Futaba-importeur:
I want to use my radio with a student's radio. How can I let the student use all of the programming, mixes, etc that my radio has to offer?
___ 1. First turn on the student radio. If it is a computerized radio, choose a clean model using the default settings of 100% on throws (ATV/EPA).
___ 2. Turn the student radio off and turn on the 9C.
___ 3. From the BASIC programming menu, select TRAINER
___ 4. Turn Dial left to activate trainer (the display changes from INH (inhibited) to OFF if trainer switch is not pulled or ON if switch is pulled.)
___ 5. Press the Cursor Down button once to move to programming aileron. You'll see AIL and FUNC (function). To give the student the same programming as the master, stay with FUNC. You can also press turn Dial Left which takes you to NORM (the student radio now sets rates, throws, mixes, etc), or OFF (which doesn't allow the student to use this channel. This is often used to keep a student from having throttle control so the instructor can control the plane's airspeed, or other functions.)
___ 6. Cursor through the aileron, throttle, elevator, and rudder controls, and confirm they are all to FUNC, or set them to fit your custom needs (by default, channel 5 through 8 are OFF, but can be changed if desired for another application).
___ 7. Next plug up the buddy box, and turn on the plane, set the MASTER transmitter on LOW rates, and match the surface throws (both direction and amount) using the ATV function on the BUDDY BOX. On low rate, you should be able to hold full up elevator on both the master box and the buddy box, and when flipping the trainer switch, see ZERO movement on the elevator. The same applies to the rudder, the throttle, and the aileron.
Now, when you pull the switch to give the buddy box control, the transmitter takes the buddy box stick movements and adds any mixes, expo, etc. that you've programmed into the Master. NOTE: while the student is in control, if high rates are desired, the appropriate switch on the MASTER box has to be pulled.
THATS IT!
Zelf zou ik eens beginnen met "rudder" op "func" te zetten en alle overige knuppelfuncties op "off". Daarna kijken of de desbetreffende functie op de juiste leerling-knuppel terecht is gekomen.
Dit kan eigenlijk niet anders: zoals Gerard al schreef is bijvoorbeeld de gasfunctie altijd op kanaal 3 van de ontvanger te vinden. Dit geldt niet alleen voor de ontvanger, maar ook voor het bericht, dat van de ene zender naar de andere wordt gestuurd. In de zogenaamde pulstrein is het 3e bericht (het 3e wagonnetje? :wink: ) altijd het gas.
