Well it's been a few days since I got my GB-03 Hotshot so I thought I would tell you what I think of it. The car comes as standard RTR with a 500mah battery, charger and adspec radio gear. The radio handset feels a little cheap and is quite bulky but works fine and fulfills the RTR role ok. The battery is a standard Tamiya 500mah and is currently giving about 20mins run time on the standard motor. The car itself is a lovely bit of minitaure engineering. Mainly plastic as can be expected but fully ballraced the car gives a good turn of speed. It's my personal opinion that the addition of a Sport Tuned motor and a larger battery will give the little car more than enough speed.
The on/off switch is in a slighly awkward position so i might think about moving it (you need to force your finger under the shell) in the future. The shocks seem quite soft so maybe some hop up ones are in order.
I got the car to travel with and use for friends and I think it fits the bill fine, tthe gold rear wheels on the Fox mini are the same as the Hotshot white ones so the first thing to do is get them changed. All Hotshots should have gold wheels!
Go out and buy one.
