New 2.4G Spread Spectrum technology allows the transmitter and receiver to be 'locked-on' to the same frequency ensuring much improved reliability and peace of mind when flying. Second, 2.4 Gigahertz systems offers quicker, more responsive control, when compared to a standard frequency system. Third, Operating at 2.4 Gigahertz also puts the radio control out of the frequency range of any 'noise' caused by the other electronic components on your helicopter - such as the motor, speed controller and any metal to metal noise - eliminating interference and glitching that can affect traditional frequency system. Fourth, another main characteristic of 2.4 Gigahertz equipment from a RC model club’s point of view is that no frequency control is needed. Eliminating the need to check everyone else's channel numbers, prior to flying. No more worries about turning up at a club with the wrong crystal in your Tx.

This is the latest 2.4Ghz Walkera MD500E 53Q3, the radio controlled helicopter, come in Ready-To-Fly package with all the necessary items inside. It is very stable and easy to fly, you can learn how to fly it in just 1 day. Its overall length is about 408mm. With compact 90 degree swashhplate structure, the servo and other parts are easy to install. The tiny 4-in-1 controller is integrated with Receiver, ESC, Gyro and Mixer with high sensitivity and strong resistance to interference. The 4-channels 2.4Ghz transmitter with over 100+ channels allows you to find different 2.4Ghz at the same time without collision, also the power indication avoids the crash caused by lack of transmitter electricity.

FEATURES

New 2.4 GHz Spread Spectrum Transmitter, Awesome Look Cabin, Reliable Spread Spectrum Mixer/Gyro Control, More Stable Flight, Even First Timer can Control Easily

New 2.4GHz technology, with the functions of automatic identification and precise code pairing, strong anti-jamming, and allow more than 20 aircrafts to fly at the same field at same time CNC-machined metal rotor head and coaxial structure, highly emulational shape with the-state-of-the-art workmanship

New flashing LED head and tail lights

2.4G 4-in-1 receiving circuit with the functions of servo extent adjustment and built-in gyro sensitivity adjustment

High performance 2 x 370SH motor, powered by 7.4V 1200mAh Lipo, offers up to 15 minutes flight time

SUPER STABLE X-ROTATION SYSTEM, Easier to control than Original LAMA

Coaxial counter-rotating blades cancel out the rotational torque that makes hovering a conventional helicopter so difficult

Precise controlling and hovering

Dual counter rotating rotor which eliminates the need for a tail rotor

Rudder is controlled using variation in speed of each level of the rotor blades

Weight Saving Spread Spectrum 4-in-1 Mixer/Gyro/Receiver Board

Reliable high quality mixer with built-in gyro board

Suitable for Indoor/Backyard/Park flying

Digital Proportional Motor Speed Control

The main rotor blades are using top quality plastic materials, which is not easily break

Separate servos from mixer, more precision movement

Trimming of servos can be done both on helicopter or on transmitter

Approximately 15 minutes flight time on each charge - Optional Li- poly battery will help to achieve better performance and longer flight time

Best choice for Beginner and Advanced hobbyist

All spare parts and accessories are available
