Hi i just recently purchased a Spektrum DX8 Transmitter,but when i tried to import my F450 & F550 SPM files from the SD card from my DX7s i find that the files are not compatible with the DX8, i was wondering if anyone had full feature spm files for the DX8, (F550 & F450 Naza) i would appreciate if you could post,pm me, or direct me to them.
