Maybe you could shed some light on how the dang thing technically performs a range test? One flyer flew to his visual limits, pressed the range button and still maintained control!
i don' t think that button does something on the range, it's like the contrast and memory model, it's only to bind with the receiver, i did not find anything about the little MCU FS8004 where the bind button goes, at power on this mcu check if bind is hold and enter in a program to match the receiver with the radio but i don't know how until we could doing reverse engineering on the program inside this MCU.
I should do some test in a few days using the RF section as a module on a Graupner MC12 without its 41 MHz quartz to see if i can send signal over 2.4GHz with the positive shift of the MC12.
I let you know if it works, i would send some photos too but i didn't get my camera back, i'll try to get it back to take a little video of the "working" test.
PS: on a french forum, a guy made a software to program the turborix (there is a linux and windows version), screen is here http://cortexet.free.fr/elico/confiture.png
