I went thru the battery wars & I sticking with FUSION you get the best bang for the buck & the battery are true to the numbers as for fukuyama never tried them but I recently tryed one motor & it was ballastic. the only problem I ever had was with was TQ cells after two race events they dumped on my 1/12th scale which got me bumped to first place in the b main I ran my fusion 1.117 & I won first place & was only 4 seconds off the tq winner
