Mini G200 Micro RC
A tough little helicopter constructed with parts usually found in higher-end offerings, the Mini G is built to withstand the inevitable crashes that are a part of any RC aviator's flight time. The Micro tends to perform tricks well, thanks to the belt-driven tail rotor that allows for more advanced aerial maneuvering (it flies well upside down) than other models in its price range. A favorite even among pros, the Micro G retails for around $350.
Art-Tech 6CH Genius 250
A unique and almost robotic design understates the 6CH's somewhat advanced control system. An LCD display on the controller allows pilots to send this little 'copter in every direction with a simple thumb flick, although control over the rudder, rotor and throttle may take some getting used to. Especially nimble in the air like the above-mentioned Mini G, the 6CH easily flies upside down over long distances and can perform tight aerial loops. The 6CH retails for about $300 in most hobby shops.
Gaui Hurricane 200SD
Not belt-driven like the other two models listed, this slightly smallish RC helicopter ideally operates indoors, away from potentially high winds. One benefit of any shaft-driven (SD) model is that very little assembly is involved, making it nearly ready for flight straight from the box. The Hurricane, being the smallest of the bunch, is said to boast the most maneuverability of the lot. Upon purchase, simply install the RC transmitter and your 'Cane will be ready for takeoff. The Gaui Hurricane 200SD retails for about $200; a belt-driven 200 model runs about $180.
