OK. I ran it on the carpet in my house and the speed is not bad.
It is a little noisy in forward but quiet in reverse.
The steering is done similarly to the Bits, where is it magnetically activated. It works rater well on this car. The steering can be adjusted like the Bits with a lever underneath.
The transmitter/ base uses a 9V battery and has a whip antenna. There is a channel underneath and alongside it to store the antenna.
The body is held on by screws. On the Viper model, the rear wing/rear ground effects need to be taken off first, held by 2 screws. There are then 2 in the front, 2 in the rear, and one in the battery compartment.
The motor is a common train-type that is flat on both sides. It looks like you could swap it out with a stock or modified motor for an HPI MicroRS4.
The electrinics look simple. No SMD stuff. Almost looks like you could get repalcement parts at RS. If a schematic can be found or produced, there should be some easy performance mods to be done here.
I don't see much room for more than 2 batteries, but it may be possible to add them under the body.
That is my review so far!
Here are a few pics:
