Product Guide

When building a flywheel blaster, there are a lot of considerations. The dimensions used to classify OFP cages refer to the motor to motor distance. All else being equal, a smaller motor to motor distance means more compression on the dart, more torque required, and more velocity. Different wheels are different diameters, and change the effective crush on the dart. The flywheel gap is equal to the motor to motor distance minus the root diameter of the wheels.

As a rough rule of thumb, 42mm smaller cages require a lot of torque, and Fangs, Hellcats, or XP180s are recommended. 43mm cages and larger can generally use 130 motors, but don’t get as much velocity. Wheels which are particularly large (Cyclones, worker high crush) or particularly small (Blasterparts, stock, and Dr. Snikkas) are roughly equivalent to jumping a size up or down on the cage.

Regarding wheel choice, I recommend my own Riot wheels for OFP cages. For more velocity and less consistency, Worker wheels are an excellent choice. The high crush large diameter Workers result in the highest velocity I’ve seen within a stock shell envelope. Artifact smooth plastic are also a good option.

Cyclones are a good smooth Delrin wheel, but have very low concavity. They are roughly equivalent to reducing gap distance by .5mm, but the low concavity is suboptimal for high crush system.

Some suggested builds to get you started:

No shell cutting: Meishel 2.0s, 43mm cage, Artifact Nylon/Riot/Worker

FVJ and Voberry Compatible: Fangs/Hellcats, 43mm cage, Artifact Nylon/Riot/Worker

High performance: Fangs/Hellcats, 41.5mm, Riot/Worker
