you will definitely get more run time out of the .21 ...i have the .24 and am running it in a jamminx2 ....i have yet to strap it up because i have a grp in there right now ...in a cen matrix i wouldnt see any advantages to running a .24 ....unless you just wanna do full throttle pulls up and down your street ...alot of people even insist that a .21 is best in a truggy as well ....they say that because of the fuel milage difference ...stick with a .21 in the cen matrix ...you will not be dissapointed .....as for the run times im looking at getting at least 12 minutes on 150cc of fuel ...in a buggy you will have 125 cc of fuel ....
