This has happen to us all who sale to try somthin new. Its happen to me alot trying to find that right car. Its all prefrence. I went from hb to mugen and got faster. Before that i went from losi to hb and got faster. All cars drive way diffrent and it take feel. Going from mbx6 to stock d8 is ganna take some getting use to. They are 2 way diffrent cars. All i can say is i loved the hb buggy and if i sell muen i know what im ganna run again.
