Testing done, I'm sticking with the 4:1's and loose tracks. I've also tested the factory grease from the nylon gears, lithium and even gun oil, but the hands down winner for gear noise reduction is moly grease. It's thick, black and sticks like nothing I've used before.

The metal roadwheels add about 4lbs (per shipping weight) which seems to be perfect. My Leo looks heavy when running without being weighed down. Excited to see them in the dirt.

If anyone is interested, I'll sell my 3 day old Taigen V2 3:158mm gears for $50 shipped (US) or trade them for 48mm 4:1 gears for my KV1. They have been run for 20min load free to condition the brushes and then have an hour of run time on them, 10min outdoors.

Now it's time to charge the batteries and go play outside.
