q, I think you are thinking of the Prodigy or the Screwdriver, the stick is not a modified flashlight. Different design....
Hi, ejfan,
Actually, the Prodigy is not based on a flashlight, although it looks like it somewhat in the CAD drawings at their website. In general, all custom PVs will be a box (Janty Stick) or a tube (Magnum, Prodigy). In the Prodigy's case, there's a tube, two end plates, a switch panel, and either a 901 or 801 adapter. All are made/machined purposefully for the device. I ordered a Prodigy because I'm turning into a battery fiend, but the Stick is certainly a good-looking bit of hardware.
