About the 1/18 Scale HPI Micro RS4 RTR

"Imagine yourself and your friends racing rc cars indoors, in garages, or on the street. You can do this because of the small size of the HPI micro rs4."

The HPI Micro RS4 RTR is a 1/18th scale electric powered rc car that is ready-to-run out of the box. The car has a single belt 4-wheel drive system, making the small car fast yet easy to drive, even for beginners.

The surprising popularity of HPI's micro rs4 is due to its small scale yet fast speeds. Indoor races are now possible... no need to go to a race track.

Buy several models and race with your friends indoors or outdoors!

Review of Micro RS4 Posted on Forums

19 mph out of the box if you buy a 6 cell battery pack to use with it

hopped up, I had mine clocked at 41mph on 8 cells and a speed 400 size motor (50% bigger than a team Orion *big block* motor)



Like 3 people on yourmicro.com has pushed their micros to about 60mph with brushless motors. Does anyone know about the 540 micro conversion? If not u guys should check it out at danmarx.org/micro/540/index.html The conversion allows u to put a 540 motor

There is actually very little in price between a mini Z and a micro hpi.... both cars can be hopped up nicely, for ultimate performance and tuning then micro is way to go, I feel the mini Z is more of a fun car though saying that there are many clubs in the US that race them successfully... Parts wise the mini Z is cheaper, though speed wise it is easier to increase micro as you can use standard radio gear... to put a really fast motor in a mini Z you need to start messing with electronics adding an aftermarket speed controller add on.
