On a similar note:
I tripped over a great little r/c helicopter called a BladeCX by eFlight.
I know helicopters are traditionally scary...way expensive, costly to repair and a spanking b**ch to fly, BUT...
This is a well-built, super-stable, fixed-pitch coaxial design. Comes everything complete in the box (which is designed to double as your flight box, too)...transmitter, Li-Po battery, charger, copter...even had all the batteries!...for $189. The coax design means two rotors, two motors, counterrotating. Counterrotating rotors means no tail rotor, and no tail rotor control. Yaw is controlled by differential rotor speed.
This little bird is only about 8oz all-up-weight, about 10" rotor diameter, and is designed to fly indoors! Any weather, day or night, you can have a quick flying fix. Hell, I've learned to take off and land in the palm of my hand! On a dead-calm day, you can fly outside. I've sailed mine right over my house, as well as out a third story window...and back.
Replacement parts are very affordable; new rotor blade = $1, new main frame = $9, new main shaft = $6 (yea..guess how I know:D ).
This is not a toy fan...it's the real deal in miniature, and I love it.
It's very popular, well regarded, and a hit with the modifications crowd. I've started working mine over already with performance improvements, and my new USAF UAV paint scheme will be done soon.
