it is worth getting the rc8 factory kit cause with the rtr u will evently bend the thinner parts on the rtr like the shock towers etc you will just spend more money,the drivetrain i think the rtr has a dogbone in the center ,and the factory team has cvd allround which u will end up getting anyways.i would remmend a novarossi .21 bf for about $170 at some places and its not to inspendsive for the engine parts,and its a 3 ports so its good for newbies like me and u ,i did 2wd nitro truck for a long time,and the buggy jumps and u can just go faster with it. the os vg.21 is the one for $150 but i heard they dont last long.the mugen is a pretty good buggy now if u dont have a hobby store local then theres pretly of parts for them online at stores.
