Interested in Vario Excavator.

[JAMMER]

You will need a motor for the pump a motor for the swing and 2 motors for the tracks, if you do not get them with the kit. Servos and a 8 channel radio. I have no Idea how to get it down the stairs. For assembly you will need something to solder with a set of metric allen wrenches and regular metric wrenches and regular and Phillips screw drivers,pliers of various types, wire strippers of some sort. As far as oil I use Cat hydraulic oil. Hope this helps you get some Idea of what you are getting into. I have one and if I can give you any help do not be afraid to ask also there are a few other here that have this excavator. I have the updated swing and chain drive for the tracks. Ed
