OK I admit it, I just bought this little truck based on its looks! The colours and design are very fetching. This is not a cheap RC toy, it's a quality hobby-grade product. Out of the box, its top speed is around 25 km/h (16 mph), possibly more? Compared to a similar model (redcat sumo), the HSP 92426 has lighter components but they are higher quality. It runs very smoothly (no strange noises), the proportional steering responds exactly, suspension is nice and soft, the 4WD wheels roll nicely.
car is very easy to drive and obeys your inputs precisely. It would make a great gift for a child aged 5 or above. It's small, safe to use and not crazy fast.
The 2.4GHz "pistol-grip" controller works fine, but be careful loading the 4xAA batteries. Don't unscrew anything!! Just push the slider up and pull the end piece off... it's a bit weird but it works.
The binding process was easy, but the "off / on" switch isn't on the ESC (error in the manual), it's under the chassis, by the battery compartment. The manual lists some complicated steps but most people won't need that. Try the factory settings first.
The battery is a 220 maH (Ni-mH 4.8V) but I haven't measured the run time yet. The battery is tightly jammed into its compartment. It has a Losi Micro-T connector but it seems the polarity is reversed from some other batteries! A Lipo battery might work here, with a careful mod (e.g. SKU097373, 4.2V, 500mAH).
I think the car needs a bit more power & speed, in order to do wheelies, flips, doughnuts. I am sure that time will test its robustness. I hope that Banggood will supply parts soon!!
