XK K127 Eagle 4 Channel Stabilized RC Helicopter Flight Test Review

This stabilized helicopter can fly 15 minutes per charge, and includes altitude hold to help new pilots take to the air. A great flier both indoors and outdoors. Find it here http://bit.ly/XK-K127

Pros
- Inexpensive helicopter for what this can do.
- Lightweight, only 51 grams. Does not require registration in most countries.
- Flybarless four channel helicopter. All stabilization is done through onboard 6G electronic gyros and accelerometers. Easy to fly with this stabilization system. It's very similar (if not the same) as flying a 6G stabilized drone.
- Includes altitude hold to help beginner pilots maintain steady elevation, especially indoors.
- Very maneuverable with swashplate cyclic control of pitch and roll (collective up/down control is through throttle power only).
- Powered by inexpensive brushed 8520 main rotor motor, and 0615 tail rotor motor.
- Also powered by inexpensive 3.7V 400mah LiPo.
- Long flier with flight times of around 15 minutes. Spare batteries are also cheap if desired (recommend purchasing them bundled with the drone to overcome LiPo battery shipping restrictions).

Cons
- Brushed motors. They will fail eventually some day. But replacement motors are cheap and widely available.
- Although the altitude hold feature eases flying, it also dampens elevation control. Up and down movement is somewhat slow. If you're a beginner, don't send this high as you'll increase the risk of losing the helicopter.
