Hey all! I've been slowly working up my McGizmo Haiku "kit." I'm slowly building up to have separate heads that each serve different purposes, and am currently looking for a 18650 tube that I can use to extend runtimes. I saw that Moddoo has made some in the past, and also saw that some people were able to use the 2x123 pak to use a 16650 instead. That would be my next option, but otherwise, does anyone make or know of anyone who makes compatible bodies for this? Thanks. Also, wasn't sure whether to put this in general custom forum, or McGizmo subforum, so please relocate if needed. Thanks again!
