First time CR-01 owner
 

i have had a few Tamiyas before but never a CR-01, unfortunately i bought it already built (second hand Ebay) and it seems i may need to take it apart and rebuild it to understand all the terminology and also understand how the thing operates. Is there anything i should not touch for fear or breaking or messing up the set up ?

Also i understand that the diff has three different settings ..... how do you change these ... i can see the hole but how do you know what setting you are at ?

I am happy to go into further detail if it would answer my questions. There seem to be little activity on this forum so i hope someone is reading this alternately is there a better place to ask ?
