Mag dump (which was an older mag fully loaded to its true capacity of 19 rounds) with streamlines, and then some chrono shots. Sorry I wasn't able to get an outdoor firing test or a target shoot or anything like that, I did this in minutes.

RapidPistol on video
Got a request for video'ing a Standard Rapidstrike on reddit. Unfortunately, the only one I had was the one in the writeup, which was a commission and just got handed off to another member of the HvZ squad. What I did have, though, was my RapidPistol, which I figured needed a little video demo.

Hey, torukmakto.
ReplyDeleteFirst of all, Great job on this mod. You've got me sold and I'm looking to recreate it.
One question though. I have chargers from my trustfire system that can also take universal 14500s and 18650s and other sorts of batteries. Should that charger be able to work for those fancy sony 18650 batteries you're using?
It's the really cheap ones such as this:

Yes, any Li-ion cell charger of that sort should be able to charge a US18650VTC3, that is a 4.2 charge voltage cell. Same goes for most other high-current cylindrical Li-ion cells such as the Samsung INR series and the Sanyos in my red packs.
DeleteBe aware, though, that my batteries are in packs, which have properly rated interconnects and wiring to provide a clean current path from those cells to the load. Using loose cells presents a challenge, which is minimizing the contact resistance of a cell holder. There is a reason most high current battery setups in industry and hobby are assembled permanently into a pack, and that is temporary-contact type holders are lacking in reliability and have too much resistance in high current applications. Almost all holders are designed for a few amps max, and people have had stampedes on fire from overheated spring terminals before, if that illustrates the magnitude of the problem.
In the flashlight hobby, spring terminals are often modded by soldering a piece of copper braid (sometimes desoldering wick) to the tip of the spring that touches the cell, and connecting the other end to the wire at the base of the spring. The copper carries the current, not the poorly conductive steel spring.
