Thanks Bigbore,

Have you ever removed the ("foil" I think) covering off Xtreme motors before? I think there are some wires or something underneath - 'cause it is a bit bunched up near the top...er bottom - opposite end to pinion!
Also can you help me with some info on how to set the pinion vs main gear MESH? This info would be very helpful. I am currently waiting on a new 3in1 as I have totally lost all power from the fore motor output of 3in1 in pic above.[]
