I have a number of these from various sources. In a 40mm single stage with Ali Express 180 motors I'm getting 45.1 m/s (~150 fps) with Worker Gen 3 HE standard weight, and an accuracy of 2.6cm/meter range (~1" per yard). At this crush, there is also an audible "snapping" sound with each shot fired, that is absent from lower crush builds. The one downside is that these wheels have production issues and there are sometimes inaccuries in the hole drilling. I have had this in 2 out of 5 pairs. However OOD are nice people and exchanged a set for me, so provided your seller is good (like this one), I can recommend these wheels.
Ok so when I say downgrade I don’t mean that as a bad thing . If swap these flywheels into the Stryfe X you’ll get down to Hvz territory which is not a bad thing . They are more concave than the stock X flywheel which lowers the crush . So if you really love the Stryfe X and would rather use it for hvz pick up these flywheels and swap em out . I will say this though the stock X flywheels will have to be cut out but definitely worth the labor.
Just a tad bit better that daybreaks in each category (idk about fps; I don’t own a chronograph), ant they even have less dart wear!.
These fantastic wheels went into a 39mm daybreak RS cage powered by kraken motors and it has my custom rapidstrike hitting around 170fps in full auto with full length darts. I plan to buy again!
The Kepler Flywheels are a solid pick for modern single stage flywheel setups.
From what I’ve seen in use, they hit a tiny bit harder than daybreaks, and have standard flywheeler accuracy.
With half lengths I’m getting an average of 160fps in a 40mm daybreak cage run by 3s Kraken motors.
Spin up is very fast, less than half a second to full rev, and handles consecutive shots like a dream.
Expect 5-10 shots per dart before they start to get heavily worn.
