Ok, im looking at getting a Yosh or FMF slip on, and a PC III. What exactly does the PC III do for the quad? i dont like having to carry a laptop on my rides because we go to a pretty remote place and i dont want to be doing a bunch of mods every ride. when i buy a PC III is it pre-programmed for the quad to run right? im not really that great at the whole mechanical thing with quads so i need the "dummy" version for it to make sense. if anyone can clear up what exactly a PC III does and if i need it that much with a slip on please help me. Many thanks!!
