md 600..
not sure CB stands for carburator, think it stands for 'basic' like phil77 says. Although they seem to make a distinction with the CBi and CB, they do not seem to do the same with the C but i am sure some 'C's have the fuel injected engine and some don't although they do not call them 'C' and 'Ci'....if you get my drift....
Anyway....so long as its ok to teach left and right PIC as per the POH (managed to confirm this with this now as a refferal back to the POH).
tks
