If anyone is looking for a relatively inexpensive R/C Enzo, I highly recommend the one from Kyosho's Mini-Z line. It's battery-powered, and comes complete with ESC and proportional radio controller with steering and throttle trim adjustments. All you need is the batteries (AAA's and AA's; highly advise rechargable NiMH's, which are good for 40-minute run times). Suspension is fairly rudimentary, but upgrades for the chassis, steering, and motor are available. The car is small and quiet enough to run in your kitchen or garage, even at ungodly hours of the night without waking anyone up. Top speed with the optional motor is about 15 mph (420 scale mph).
$150 at your local hobby shop or
www.towerhobbies.com. Recommend getting the $12 upgrade motor, bearing set, and carbon suspension plate.
