Bests & Worsts Reviews from Amazon

Can't complain. My 2 year old and I have put this machine to the test. It's ran through tall grass, up and down hills, and all over the countryside. It may not be the fastest machine on the block, but it doesn't quit. I have upgraded the stock 7AH battery to twin 12AH units as there's a precast 2nd battery housing in the passenger side engine bay, and I routed the radio antenna up through the windshield housing which greatly improved the radio reception. However, if you do add a second battery, please make sure they're wired in parallel, as wiring them in series will produce 24V, and burn up either the motors or gearboxes in very short order. On that note, while I was replacing the stock 18? 16?ga. wiring to the motors with 12ga. to ensure the most efficient power transmission, I split apart one of the gearboxes and was rather impressed. While everything was of course plastic, it was all good reinforced nylon and the fit and finish in assembly seemed solid. I would venture under normal operating conditions the failure mode of this machine will be the electronics under the hood. The remote control seems great out to at least a couple hundred feet with direct line of sight and at least with my toddler quickly averted his poor steering choices. When all else fails the "P" button on the remote kills all power to the driveline. Overall, this machine has seen dozens of hours of use in lots of different conditions, many of which it was probably not designed nor intended to endure, and has performed admirably.
