Endpoint Adjustment

Endpoint Adjustment : This radio feature adjusts the length of servo travel in one direction (a single channel will have adjustments for two endpoints). If your plane rolls faster one way than the other, endpoint adjustments can correct the problem.

ESC - Electronic Speed Control

Electronic Speed Control (ESC): Electronic speed controls replace the mechanical speed control and servo providing enhanced power efficiency and precision in an electric R/C car, airplane, helicopter or boat. In addition, they are lighter which improves the performance of some electric models.

Wikipedia:
An electronic speed control or ESC is an electronic circuit with the purpose to vary an electric motor's speed, its direction and possibly also to act as a dynamic brake. ESCs are often used on electrically powered radio controlled models, with the variety most often used for brushless motors essentially providing an electronically-generated three phase electric power low voltage source of energy for the motor.

An ESC can be a stand-alone unit which plugs into the receiver's throttle control channel or incorporated into the receiver itself, as is the case in most toy-grade R/C vehicles. Some R/C manufacturers that install proprietary hobby-grade electronics in their entry-level vehicles, vessels or aircraft use onboard electronics that combine the two on a single circuit board.

Cars
ESCs designed for sport use in cars generally have reversing capability; newer sport controls can have the reversing ability overridden so that it can not be used in a race. Controls designed specifically for racing and even some sport controls have the added advantage of dynamic braking capability. The ESC forces the motor to act as a generator by placing an electrical load across the armature. This in turn makes the armature harder to turn, thus slowing or stopping the model. Some controllers add the benefit of regenerative braking.

Helicopters 
ESCs designed for radio-control helicopters do not require a braking feature (since the one way bearing would render it useless anyhow) nor do they require reverse direction (although it can be helpful since the motor wires can often be difficult to access and change once installed). Many high-end helicopter ESCs provide a "Governor mode" which fixes the motor RPM to a set speed, greatly aiding CCPM-based flight.

Airplanes 
ESCs designed for radio-control airplanes usually contain a few safety features. If the power coming from the battery is insufficient to continue running the electric motor the ESC will reduce or cut off power to the motor while allowing continued use of ailerons, rudder and elevator function. This allows the pilot to retain control of the airplane to glide or fly on low power to safety.

Boats
ESCs designed for boats are by necessity waterproof. Also, many are water-cooled. Like cars, boats need braking and reverse capability.

DSC - Direct Servo Control

This radio feature permits you to check servo operation without broadcasting a radio signal. A cable connects the transmitter to the receiver. Direct servo control is very useful for on-the-ground control checks.

Futaba Description:
Direct Servo Control (DSC): High-end convenience feature which allows control/adjustment of servo function without sending signal through receiver. Requires optional DSC cord (FUTM4250) and DSC-compatible receiver such as R149DP and R113IP.

T-REX 100X Super Combo KX022005A

T-REX 100X Super Combo KX022005A Rc Helicopter

Introduction:

• Fun and easy flying characteristic has been the reason for T-Rex 100S’s unparallel popularity. To increase its performance even further, Align has improved upon the T-Rex 100S and introduces the brand new T-Rex 100X.
• To improve the flight stability and shorter learning curve, rotor head assembly features a new mounting method between rotor head and main shaft, and the surface area of flybar paddle has been increased. In addition to interchangeable stick mode on the transmitter, stick tension is also adjustable. Transmitter also feature gyro gain adjustment for simple tail sensitivity tuning.
• But the most unique feature is that T-Rex 100X can also be controlled through an iPhone, allowing pilot to experience a completely different flying method.
• Superior flight stability and quality assurance, for immediate indoor flying gratification, T-Rex 100X is the prime choice for any pilot!

Features:

• Brand new rotor head to main shaft attachment design, improving flight stability and minimize vibration.
• Transmitter sticks’ tension can be adjusted to suit pilot’s preference.
• High contrast LCD display screen.
• Extended tailboom to improve gyro tail locking ability and overall controllability.
• Remote gyro gain adjustment on transmitter for ease of tail tuning.
• Supports iPhone/Android as controller using specific transmitter attachment.
• Brand new canopy design.
• Utilizes AFHDS 2.4Ghz automatic frequency hopping technology for stable signal and interference avoidance.
• Transmitter has trainer port capable of interfacing with third party flight simulators on PC. Interface cable is included.
• Support mode 1, 2, and 3 transmitter stick layout.
• Increased flybar paddle to effectively increase flight stability.
• Utilizes hobby grade micro servos and increased frame rigidity, for flight stability, crash survivability, and longevity.
• Built in Nimh and Lipo battery charger which can be used while flying.
• Convenient USB charging jack allowing universal compatibility with PC’s USB port, or any 5v USB travel charger to charge transmitter’s Nimh battery.
• Charging status and capacity display.
• 5-in-1 circuitry includes receiver, ESC, heading lock gyro, servos, and mixing function.

Users must have a certain concept of security to operate the R/C helicopters.
Be sure to read and comply with related safety notes of instruction manual before flying.
