Thats cool! My son runs a converted raze with RC Monster motor mount, homemade battery tray. Hes 6 years old. Hes running the 1900kv Hobby City motor on 3s on my backyard track.
LOL I need an updated picture because I now have a traxxas slash radio box glued down instead of the rubber dart.
He hasnt blown up any diffs yet but when he does, Ill go with hyper 7 gears.. Thanks for that info! Nice build and keep us updated on how it does in the sand.
