Ok i just measured the main shaft dia and its 4mm. I don't have V200D03 but did order its head to convert my 4F200 into two blade heli and after comparing 'em it appears to me that the head parts of both helis are inter-changeable like rotor head, main blade grips, swashplate, feathering shaft etc.
I've few Tarot 250 tail booms lying around which are 8mm in dia, same as master cp boom though i guess there length would be the same as well but can't confirm as it would require me to dis-mental my master cp tail boom.
Master CP main blades are 210mm in length from root to tip and 200m from bolt hole to tip.
