humm yea i know what the difference is. and yea they are the real ms pro's with booster.... the two bodys. and the 2.2 it says PRO in red... in case you didnt already know there already are 6 avilable freq... but they are usually not all avilable in one country... FCC regulations only allow 2 frequencys for R/C cars so you would have to think that to get all 6 freq you might have to have interchangable crystals... Believe me there is no wondering about it! these are the real things!!!!!!!!!!!
heres the pic
the only cars that i have seen that use the AAA batteries are the zipzaps, and the cannonballs.. or the ones that have the seperate charger.. clones are incosistant but that is a major difference so it may be the same company that makes the prescious but it would probably be manf. under a different name.... i doubt that any prescous use AAA's but i could be wrong
