The Big Drone by Walkera - QR X400 Quadcopter
Although we say it is a Big quadcopter, but actually it's still a small drone made for "Expereinced Beginners".... what does that means? The QR X400 is so very stable, if you have experience on Co-Axial helis before and with no crashing, you should be able to hover the QR X400 with ease. And for "Experienced" players, you can do flips on this big thing. Just take her high, flip the "Flight Mode" switch on the transmitter and push the elevator stick to max, it will do a flip in mid air and regain level afterwards, amazing isn't it?
The QR X400 bigger features is the Flipping trick which the old one can't. Because QR X400 has newer Speed Controllers and Brushless Motors, and a better 6-Axis Gyro, so it is possible to do tricks, in another word, QR X400 can carry more payload because of the better power system. The Walkera QR X400 is a very fun quadcopter for leisure flying and carrying something, for the moment, you may need to DIY some camera mount or some hook to carry the payload.
