For example,
EngineOnOff=4;0=NOT_USED, 1=UPSX_DIAG, 2=UPDX_DIAG, 3=DOWNSX_DIAG, 4=DOWNDX_DIAG, 5=CH5, 6=CH6, 7=CH7, 8=CH8
What do I do here, do I delete the ones not wanted, or do I highlight the one I want.
I have been through the forums and found nothing on the actual how to bit for computer numpties, it may sound simple to folk who know their way round software hieroglyphs, but to me and I'm sure plenty of others it's dark magic, plus what happens if I press the wrong button.

I've been in the "ini" files and even when it states microSD root, that has me lost, what is an sd root.
I'm not totally green when it comes to rc, I've been flying for 30 years, everything from micro indoor planes to 6m wingspan full composite gilders to 20kg 1/4 scale warbirds where the only thing you programmed was your tx, which mine is 32ch, everything else was mechanical, electrical or pneumatic.
Any layman's type ifo would be much appreciated.
