I know the plastic 4#3 has been around for a while so I'm sure someone has done some upgrading if possible. What's the biggest motor/battery configuration possible on this, or is it pretty much maxed out when you get it?
With some minor mods you can go brushless.
Haven't gotten my 4#3B yet but I have all the gear ready to convert it as well.
