Take it away, Leo!
Keeping it simple may be the answer to XK Innovation’s success recently.
XK X251 is a new mini quadcopter with powerful brushless motors, designed to be fast and swift. If you are looking for a swift little quadcopter, this may be it, the XK X251 WhirlWind. Shortly after the initial release, a version 2 was introduced with some slight modifications to cater for beginners.
This quadcopter is very fast and can take a nice punch (vertical take-off).
It is easy to fly if you have flown a quadcopter and have mastered your flight orientation. The XK radios are well made as always, but the spinning dial that gets in the way is still there on the right. The beeping spinning dial is not in the most practical position to reach while flying, but for this aircraft, it is only used to navigate the menu. The material is a mixed of carbon fiber structure with light-weight Acrylonitrile Butadiene Styrene (ABS), a common thermoplastic polymer (also used by Lego), strong but will destruct on direct impact at high speed. It does not break easily out in the field, if it just falls out of the sky, as the total weight is only 205 grams.
Version 2, great for the beginners, auto flips and returns to rear facing.

What To Expect If This Is Your First Quadcopter
You can easily spend 12 minutes on each flight, setting up and flying. The actual flight may last 5-10 minutes from our tests. On a Mode 2 radio transmitter, throttle stick is on the left.
Power on your radio transmitter first, make sure your throttle stick is at the lowest point. Check to make sure all your switches are up (position 0). Connect your battery to your copter, lay the copter flat on a hard surface immediately. This will allow the copter to self-level the gyroscope.
Once the red and yellow stops flashes stops, you have successfully binded with the radio. A green LED indicates you are in 6-axis gyro mode and a red LED indicates you are in 3D mode. To fly, flip the throttle hold switch down “on”, the copter is now live. To lock (disarm), move your left throttle stick down to the lowest point and flip the throttle hold switch back to “off”.
The copter LiPo battery may get a little warm after each flight. When the voltage is low (7 volts), you should manually land within 30 seconds to prevent the battery from over-discharging. Over-discharging a LiPo battery below 3 volts per cell, can permanently damage the battery. It is best to let the LiPo cool down before the next charge.
There are dual rates assigned to the right switch.
The XK X251 is swift, with precision responsive controls.
