This upgrade to the popular JJRC X1 quadcopter includes a redesigned structure for improved durability in crashes. Find it here goo.gl/6Js4iB
Pros
- One of the lowest cost brushless motor quadcopters currently available.
- Redesigned thicker structure for improved durability (as compared to previous X1 model).
- Good fast flier with powerful motors.
- Good introductory brushless motor quadcopter for intermediate fliers.
Cons
- Some quality control issues. Recommend checking and tightening all motor mount screws and prop nuts before first flight.
- Instruction manual was difficult to understand and incomplete.
- Procedure to arm/start the motors is unusual and not fully covered in the user manual. Startup procedure is... 1) turn on quadcopter and place on flat/level surface, 2) turn on transmitter and wait for binding beep, 3) calibrate gyros by moving both sticks down and to the right. Hold there until you hear three quick beeps and one long beep, 4) press upper left shoulder button to bring the motors to idle start.
- Some unusual wobble was experienced in hard turns.
