Eachine E129 - Beginner's single-rotor helicopter

This is a little demo of the Eachine E129, a fully stabilized helicopter with altitude hold and self take-off and landing ability. The E129 is a fixed-pitch helicopter, meaning the blades do not change pitch / attack angle to rise or drop. Altitude is strictly controlled by motor speed, and motor speed is strictly controlled by the flight control circuit board. Instead of throttle / collective pitch control with the throttle stick, the included transmitter has a spring-loaded throttle stick held in the middle position. Moving the stick up or down tells the onboard electronics to do just that, and it speeds up or slows the motor accordingly. Release the stick and it snaps back to the middle location, the helicopter then stops rising or dropping and attempts to hold whatever altitude it is at upon stick-release. Fully automatic. Easy to operate. Makes it impossible to cut throttle and fall to the ground like a rock, as some beginners have unhappily experienced with standard collective pitch heli's. The E129 DOES have a swash plate and two servos to provide proper cyclic blade pitch for left-right-forward-back maneuvering, though pitch and bank angle are greatly restricted by the gyro system to about 15° to 20° degrees from level. This helps beginners from over-controlling and falling out of the sky. Operation is very easy. Anyone can get it in the air. If you hit and break something, parts are available and relatively cheap compared to some brands. I got the entire RTF heli for around $50 with one battery pack. Get it with two or 3 packs if you can, so that you can have one pack charging, one pack flying and pack #3 charged and standing ready for the next flight. The E129 has 1-button takeoff and landing, high and low speed modes and the ability to switch between transmitter type MODE 1 (throttle on right stick, Europe common) or MODE 2 (throttle on left stick, USA common). It has no throttle stick but rather a spring-loaded stick you use to direct the heli to go up or down and how quickly to do so to a point. The bird will rise or fall slowly with no sudden motions. If you need it to fall to the ground fast, then either get a shotgun and treat it like a clay pigeon or less forget it. Gotta have patience and react early. It doesn't do anything quickly or suddenly except for maybe auto-takeoffs (necessary to get off the ground quickly). I have one negative point to mention about the E129. The controls are not as smooth and linear as I would like. They feel like they have very strong expo set on them so that a small stick motion induces a small reaction from the heli, but then just a little more suddenly produces a big reaction. The servos seem to reach full-travel when the stick has only been moved through 50% of it's travel range. Too touchy for my tastes. I find making smooth turns difficult with the E129 because the tail rotor does not feel like it has any RPM speeds between yawing the tail slowly and moving it fast, almost like hitting high/low switches for motion rather than proportional movement matching the control stick motion. Not happy with that. WHEN I flew the beginner Eachine E120 / C186 helicopter, the controls felt very linear and smooth, and I felt comfortable flying it indoors. The E129 made me feel uncomfortable flying in a room in comparison. Just not as well-programmed I guess. The E120 is a newer machine. So there you have it. Beginners will have fun with the E129 and you can buy one cheap if you shop around. But in my honest opinion I suggest passing it up for the E120 (also called C186 and BO-105) which is 2S powered and has optical flow position holding as well. The E120 is a superior bird for not much more money (got mine for $65 shipped). I hope someone found this information and video useful. Happy flying!
