Okay thanks for explaining… that totally clears up my confusion, and gave me ideas…
Got me thinking about putting 3x XPL-HI into my C8F V1 (tail switch only version) for a WML.
IIRC it also has a standard size mcpcb that I might be able to find with the emitters already mounted, then add a FET/DD driver.
.
Yeah I was reading about his tail switch mod, seemed a bit over my head to build one myself from his parts. Great solution though for a long standing drawback of those remote switches.
