I know people use the "you will uncover dangers" blah blah a blah

I have a apexi power fc and considering buying a datalogit and maybe giving mapping a go, I already have a innovate wide and sensor so thinking,,,, could it be relative easy ?

Also if I'm honest i do doubt trusting people as you don't get warranty ect and I have seen crap happen with mapping so its why I'm asking could I give it a go perhaps ?
