Nitro RC cars is my hobby, hpi rs4 evo3 1/10th scale on road car all hopped up- all aluminum accessories they make i have them! spent way too much on this car! , will do 68mph with my small gears! bigger gears have never been checked... Ofna hyper7 off road buggy 1/10th scale with minor mods just overall fun! and HPI savage X 1/8th scale monster truck with lots of mods... 3 speed trans,tuned exhaust pipe,header pipe,shocks,roll cage,wheels tires, clutch, gears, brake upgrade etc this is what i do in my 15 minutes of downtime a day
need more play time and less work time! My kids have 1/16th scale nitro buggies also.. its a blast!
