I will try to sum up answers to the most common questions about these cars for people who might be considering one.
A. It takes about 2 1/2 minutes to charge with roughly 7-10 minutes run time.
B. An Epoch charging stand will charge one of these which is nice because the epoch charging stand has a jack for an ac power adapter. However, anyone with a basic knowledge of wiring or electronics could add an ac adapter jack to the corvette/viper/dg master charging stand.
C. Stepped proportional control. Approx 5-6 steps each way for steering and the same for speed control. Not nearly as good as an Epoch but not bad. Steering is not quite as fast or precise as the epochs.
D. The manual states that top speed is 490 feet per minute which works out to be about 5 1/2 MPH. The car seems faster than that. It may be the size that gives it a greater illusion of speed.
E. These cars can turn in a circle as small as approx. 1 foot at the slowest speed. The turning circle increases dramatically as the car is driven faster. The lack of a differential and the amount of torque are probably the main culprits.
F. These cars handle better on a surface that provides good grip. Smooth concrete and harwood or tile floors will be more of a challenge. The treaded Superslick tires seem to provide somewhat better grip but the stock slick tires provide decent grip also. Cleaning both the tires and the track surface regularly will help with grip.
G. Like most rear drive rc cars that lack a differential, these cars tend to turn a little better one way as opposed to the other. My viper tends to wipe out easier when making right hand turns as opposed to left hand turns. My corvette has a wider turning circle to the right compared to the viper which makes it harder to wipe out. I am not sure whether this is a production change made to the corvettes to make them easier to handle or just variations in production quality.
H. The transmitter is one of the better micro car transmitters in my opinion. It folds up, has a decent grip, and the steering wheel is about the same size as a mini-z or xmods steering wheel. As mentioned before there is an A,B,C switch on both the car and the transmitter for changing channels. These cars use a concept called wavecoding to create the different channels as opposed to crystals. There does not seem to be interference from one channel to another. However, because of this technology, I doubt if a standard transmitter would work with one of these. Steering trim is on the car as opposed to being on the transmitter. There is no throttle trim control but it does not seem to need one. The range and amount of interference will vary depending on where you use it of course. I get roughly a 30' range in my basement.
I. Overall I would say that these cars are not as precise and refined as the epoch cars but they are not that bad either. In some respects comparing the cars is similar to comparing xmods to mini-z's in my opinion. Like the xmods, these cars are better suited for a track with an emphasis on speed as opposed to a track with lots of tight turns in my opinion.
