We were very happy to buy the car and the extra battery for our son for
Christmas. I am enough mechanically gifted, my son is an engineer who any car
repair address, including the reconstruction of the vehicle transmission and
rear differential.
The charger connection would not use the extra battery, disappiontment. The
car worked very well for the first store, quick, agile. In the second race, he
left point. Multimeter showed the power of the engine, the engine would not
turn over, shown Remove broken in the case motor intestines through the slot.
Down to local hobby shop, new engine and the adapter to load the initial
and additional battery. Partly through the implementation of the battery 3,
developed a sound beam acceleration slip rear differential. The research shows
that the planetary gears used in the original diff enough jump / slide on the
side gears, stripping spiders.
Amazon buying a secondary market diff intestine works like a Detroit locker
and mounting repaired temporarily. I returned the car, but that was when the
grandson was visiting from out of state. ONLY buy this if you are mechanically
gifted and willing to tinker with it.
A big disappointment. I have 2 stars only because it performs great when it
works
