HJELP!!!
Jeg handlet meg en brukt Futaba 9Z i den (van)tro at den skulle være like enkel å gjøre om fra mode2 til mode1 (ja, jeg flyr faktisk mode1...) som min gamle FF7..
Men akk..
Jeg ringte NM, og de var meget hjelpsomme, men var ikke helt sikre på om de kunne ta på seg oppgaven. De skulle til og med kontakte en annen kunde som hadde gjort dette tidligere, for å se om han kunne hjelpe meg!
MEN..
For å spille på flere kort:
Er det noen her på forumet som kan slikt??
Jeg har en oppskrift fra nettet, men jeg er ikke såååå stødig med bittesmå kretskort o.l.
Info fra nettet:
...... The physical conversion is relatively simple for someone who can carefully unplug a few cables and lift one of the PCBs (*). However, once the physical alternations are made it is necessary to recalibrate the sticks due to elevator and throttle having different amount of travel. If such calibration in not performed the unwanted effects include increased elevator servo throw (beyond the radio’s specifications) and throttle/pitch curve points 1,2,12,13 becoming unreachable. Again the service menu will allow you to perform such a task (**).
(*) Physical conversion of the stick mode requires disassembly of the transmitter which includes temporary removal of one circuit board. However, once access to the rear of the joysticks is possible, conversion can be performed fairly easy. People often mistaken and swap the two joysticks around. This is not required and in fact will cause confusion as the stick positions will no longer correspond to the trims and to what is shown on the screen of the transmitter. If you take a careful look at the joystick mechanics you will notice that the throttle axis has a spring too which is retained extended by a plastic tab to prevent automatic centring of the throttle. There are also two limiters that reduce its full through. All that is required for the stick mode conversion is to remove the tab and the two limiters and install them at the other joystick. At this point you have two options. The first one involves the replacement of R133 (see above) which will result in a perfect conversion where your radio will function as if it was manufactured for this new stick mode. Your second option is to proceed without replacing R133. However, you will still need to calibrate the sticks as J2 and J3 now have different through than before. Additionally, since R133 is not replaced the transmitter is not aware of the new stick layout, thus every time you create a new model program (or reset a model program) you will have to go to FNC menu and manually define how the sticks and trims are coupled with the output servo channels.
(**) Futaba distributors in USA found a quick way to resolve this issue without revealing the service menu. They recommend a full hardware reset. Such reset erases all calibration parameters and loads some default values. These default values are approximate values for any newly manufactured transmitter and they represent calibration values of both elevator and throttle being of short stick travel. This procedure will resolve the problem of throttle/pitch curve points being unreachable, however the increased elevator servo throw will remain. The reset will also wipe the factory calibration of the voltmeters, in which case the voltmeters will continue to function but they may have reduced accuracy. Loss of neutral point calibration may also affect the aircraft’s trimming upon activation of Dual Rates as discussed above.
Mye info, men
Håper på hjelp................

Fzzzzzzzzzzzzzzt, hva brenner?
(og jeg fikk beskjed om at de ikke var villige til å ta på seg reparasjon av 9z lengre)
