Most recent is ball bearing installation by antisplat aero. Also grove makes a different wheel with better axle setup. I have axle spacer made by i think matco. seems to help but i still have significant drag from the seals. Antisplat solution looks the best to me now.
Also check that the nut is tight at the top of the nose gear leg (where it
attaches to the motor mount). I use the Grove nose wheel and run the tire
pressure at 42 lbs. I also adjust the break out force to about 32 lbs.
Works for me, YMMV
