The main problem with stock flywheel motors is they aren't powerful enough to actually shoot darts by themselves. Rather, it's the energy stored up in the flywheels that's actually doing the work. The rotational momentum that builds up in the flywheels is transferred to the darts as they pass through the cage. The darts speed up, as the flywheels slow down.

That means the stock motors need a few fractions of a second to bring the flywheels back up to speed before they're ready to fire the next dart. As a result, even the best stock motors and batteries are limited to about 10 darts per second, give or take. If you attempt to feed darts much faster, they just dribble out the front of the barrel.

To fix this problem, you need to substitute the stock 130 motors with replacement motors that generate higher torque. "Torque" is the force a motor generates - sometimes called "power". Higher torque motors can pull darts through the cage faster, and generate higher rates of fire, as well as higher velocities.

For instance, Fang ReVamps generate enough torque (aka power) to accelerate darts to 100+ FPS from a standstill, assuming the batteries can provide the necessary stall current. In other words, Fangs are powerful enough to actually flick darts out of a blaster as fast as you can feed them into the flywheel cage. That's simply not possible with stock motors and batteries.

So you're right Demon², it has nothing to do with the darts. It's the crappy stock motors, and to a lesser degree, crappy grocery store alkaline batteries.
