Revo 3.3 Tranny with all Metal Gears problem

[BrianG]

I haven't worked with the metal gear set (yet), so I have no experience with it.

You could file larger half-moon shapes - no harm in that at all. But, will you be able to tap screw threads into those hardened gears?

I've been toying with getting the RR set, but have held off...

One thing I'm curious about; how is the idler gear held onto the shaft (the one right in front of the second gear)? Does the metal set use the same chintzy pin, or did RR provide an alternate and stronger setup - like maybe grub screws?

BTW: to focus your camera better, try pushing the shutter button just part way (this is where most cameras do the auto-focus operation). Once the pic is focused, push the button all the way. Or, you may need to enable the macro setting. Usually, this is represented by some sort of icon that looks like a flower (for close shots) and/or a mountain (for far shots).
