Very funny to build - it's better to have the complete ball bearings set, because dismounting the complete vehicle for a later upgrade will be a mess. It's very realistic.
If well assembled runs very smootly on every surface, and it's very good looking. The gearshift is working very well. There is the option for the 4 wheel steering, but a high torque servo is recommended. Unfortunately, a strong servo will break the servo arm in the kit if not range limited in some way.
