Another update, sorry to bore most of you
I'm now getting a horrible whining sound from the BX II when I open the throttle up. The actual motor gear cog and big plastic cog at the back seem in perfect condition, so I guess its something to do with the diff. Time to open her up and have a look me thinks...
Fishing the rolling chassis for the Smacker too
And, I bought a Tamiya Bullhead off eBay for even more bashing!
