@ a&c: flying a microlight, I am supposed to never come anywhere near a cloud anyway. If I consider an AI, it is just against the odd chance of finding myself where I never ought to be.
@cumulusrider: though it is against my nature and upbringing, I am making a fair effort of using as many codes, abbreviations and acronyms as I can manage, because that is obviously the correct way of posting here.
@all: thanks for the pointers, but I have failed to make clear that (having some skills at soldering and PCB design) I was thinking of a homebrew concoction around the R/C heli sensors. Apologies for not being sufficiently clear.
