3/8" hex gears that are slightly thinner. 1/2" hex has been amazing however for some applications you want to use gears but the current hex line from Vexpro just seems overkill and you are throwing extra weight and space where you don't need to.
+1 for a Versatube spacer.
1/2" hex bevel gears. Would have come in handy this year but with only 3/8" available and all of our existing system being 1/2" hex it made it just about impossible to integrate.
After this season, a non plastic dead axle hub for 6" and 8" wheels would be nice but this is mostly game dependent.
