I Can see how the little micro-sized M17 could "grow" on your hobby engine's "gotta have" list & hope their Is a functional H & M version available.....But, if not, Would make a challenging conversion project, along with fixing the sparkplug "thing" issue...A micro-sized, in-scale "igniter" mod would be kinda cool !! As a H & M ownership newbie (M-90), I'm still well down the slowest hits per min/Rpm "rabbits Hole" pursuit which tends to pull one to simply bigger-heavier physics size, but a Really slow hitting, H & M  Micro could be the latest, leading edge vintage model engine novelty!!
