RE: 14MZ 2.4 file additions ?
No, the plug on the side is a USB plug, exclusively at this time for factory use. You won't find drivers for it and you cannot use it. Take the card out and use a standard card reader with your computer. No drivers are needed.
R616FFM 6-Channel Micro Parkflyer Receiver is the smalles receiver you can get to work with 14MZ. At 6,3 grams, with the case included I guess is small enough for anything. However, be advised, it comes with Futaba micro servo plugs, not with normal servo plugs. You will need some adapters, which will spoil the weight you gain from the small receiver OR you can buy special servos from Futaba with micro plugs.
