The first rc electric cars started to be seen in the UK in mid 60’s and the first manufacture starting to sell their models in the shops were the likes of Mardave. In the early days these remote controlled models were very primitive and very different to the adjustability and performance of today's models.
Massive advancements in radio controlled electric rc cars have been made over the last few years. The two main advancements for rc electric cars is the introduction of LiPo battery technology and brushless motors. Both of these allowing electric rc cars to have longer run times than ever before with greater acceleration and higher top end speeds. In some cases faster than nitro models!
Most of the manufactures now offer their models in both "kit" and Ready-To-Run (RTR) versions. Both options have their advantages with most of the kit versions having higher spec Hop-Ups already included in the kit. If it's your first RC Model then it's more advisable to go for the Ready-To-Run (RTR) version. With this version you get everything you need straight out of the box to get you having fun with your new model.
With all models you need a power source to propel your model. In most cases these models run off a 7.2v stick battery which is either a 6 cell Nihm battery or a 2 cell LiPo battery. In some models you can increase the number of cells of the battery to give a higher voltage output which in turn will give a faster speed to the model. Please be careful in doing this to your model because other parts of your model may require further Hop-ups to obtain these higher speeds. This is due to higher stresses put on your model when accelerating at higher speeds.
Currently the fastest commercial available RC Model is the Traxxas TRX64077. This model can reach speeds of 100mph which is 1000mph scaled!!
Always remember to charge your batteries........
