Worker Standard Crush Flywheels (pair)

Works great but Fragile

nice tight fit, but I found out the hard way that they are almost guaranteed to break if you try to remove them, even with a 2 pronged push tool from behind, one of the flywheels cracked then broke during removal from the motor shaft. The second has stress marks on it around the motor Point. Ended up ordering a second pair. The second pair I ordered worked terrific, so as long as you do not ever need remove them they seem to work great with a soft tipped dart. They'll melt hard tipped darts really quick however! These are a TIGHT fit for a reason, use a small press to put them on, no drilling required.

These are great for the money, though they do require slight modification to use with 2mm motor shafts.

Modification required for smooth 2mm shaft motors
