Well judging from that, the previous own must of gotten rid of the switch for some reason, as there is no sign of wire for a on off switch, it seems to drive on with the lipo plugged in, I'll run it properly tomorrow and see how it goes. Once final question for now is, how do I know if the mesh is right between the spur and the pinion gear? It seems a little tight/rachety at the moment, and from my nitro days I know that you could use a sheet of paper to set it, however i know these motors can be pretty powerful and i dont want to strip a gear on my first run out!
