RE: Transmitter virus (?)
A computer virus is software meant to disrupt your system and spread itself. In any RC transmitter, the only way a virus could get is is via a corrupt model file, but that's not an executable. If you get a corrupted update file, then you did not get it from an authorized Futaba source. If someone wrote such malevolent code, how will they get you to spread it? If you get a virus, it would be easy to get rid of. Just download the update file from a trusted source and update your transmitter. Worst case? Send it in to the service center for a memory wipe and cold restart.
By the way, the Futaba 14MZ is the only transmitter that used any kind of Microsoft code, using Windows CE, which is NOT the same as the Windows code you have in your PC or laptop. They are not inter-compatible, so a virus on your PC cannot infect your transmitter.
