Better for gearing

I don't fly monster headspeed so stepping it down one is what I need.

Great fit for Goblin 630

I have tried 21 and 23 tooth pulleys with 530 and 550kV motors, and 626 and 640mm blades on my Goblin 630 Competition. For either kV, I would recommend using 626mm blades with the 21T pulley, and 640mm blades with the 23T pulley. The latter configuration has more punch and definitely requires more power / amps.

Fits Perfect/Runs True

This pulley fits my Scorpion 6mm motor shaft perfect. There is no slop, yet I did not have to force it on. It runs true with no wobble.

Using this pulley on a Velos so you could say that I'm using two of these pulleys. No issues with build quality and it's working great, no slippage. One pulley was tight getting on but nothing a little oil couldn't fix.
