>>5333632I've been using quad 4.2v Trustfires on my stampedes for years without issue. They're bretty good for responsiveness. Still, I find that flywheel blasters and automatic plunger blasters just can't stack up to traditional in a straight firefight. They'll always have a small delay and are never as accurate as a good long barrel plunger. That's why I only keep my Stampede SMGs around as a secondary. Pic related. Radio shack has tons of cheap battery holders you can solder into the place of the obnoxiously large nerf ones.
