Ready to fly weight (no fuel) is an incredible 3.20Kg (7lbs) Including mixture servo mount for installing an engine temperature controller.

Transmitter - Spektrum DX7

The 7-channel DX7 uses the DSM2™ technology and includes an impressive list of programming features for helicopters that are simple to access and use. The DX7 is also compatible with all existing Spektrum aircraft receivers. Whatever kind of flying you do, the DX7 can be used for any existing Helicopter that requires 7-channels or less. This is perfect for the T-rex 600N RC Helicopter.

 

 

 

Receiver - Spektrum AR7000 -DSM2 

This is the seven channel DSM2 receiver from Spektrum. Comprised of a compact main receiver that is linked to an even smaller satellite receiver by a 6" lead, the AR7000 acts as a pair of extremely sharp RF "eyes" that each take in a slightly different view of the signal environment. Information from both receivers is then processed by patent-pending Spektrum software that takes information from each receiver and combines it to form the most vivid "picture" of an RF signal than has ever been possible in RC before.

Features:

7 Channels

External and internal receiver

DuaLink™

Model Match (prevents flying a model using the wrong model memory)

ServoSync (feature does not work with module systems)

SmartSafe fail-safe system

1024 resolution

 

Note: The AR7000 features DSM2 technology and is only compatible with DSM2 transmitters. The AR7000 will not operate with the DX6 or Spektrum® surface systems, and is only compatible with DSM2 radio systems.

 

Futaba GY611 Head lock gyro 

The GY-611 is one at the top of Futaba's extensive range of gyros and as such; it is openly marketed as their interpretation of the ultimate gyro technology. The actual GY-611 sensor utilises the latest Silicon Micro Machine (SMM) type of sensing and is mounted in a very compact low-back aerofoam case to improve vibration resistance and neutral characteristics.

Align B6T 2 In 1 Voltage Regulator Combo

New Align B6T 2 In 1 Voltage Regulator Combo HE50H11. Great for the Align Trex Nitro Helicopter. Special greaseproof/waterproof design, much reduce damages caused by fuel and water infiltration. Add filter capacitor for high frequency interference, to efficiently reduce the outside interferences (ex. High speed/torque servos). Due to the unique 2 in 1 design, the regulator’s functions provide power to the receiver, servos, and the internal glow plug ignition system that does not require you to remove the clip lead. The linear regulator design results in no interference to the receiver. The required input power may only consist of a 2 cell Li-ion or a Li-Poly battery. When the integrated power switch is moved to the on position, the voltage indicating LED’s and ignition indicating LED’s will illuminate displaying the status of the battery voltage, and of the plug ignition function.

All in all

A lot of Helicopter for your money, again quality of parts are second to none. The Gyro and servo are top quality on this build but you could get a way with a GY401 and cheaper option on the servo. A Trex 600 is really something to watch dancing in the right hands.
