The Sport BEC is a high capacity switch mode BEC (battery eliminator circuit) for RC models.

One of the main features of the Sport BEC is that it can provide two levels of voltage to your servos. A small switch on the side of the Sport BEC lets you choose either a 5 volt output, or 6 volts for greater servo responsiveness, speed, and torque. This is great for RC helicopters, which need the servos to operate as fast and crisply as possible.

The Sport BEC connects to your electric system between the ESC (electric speed controller) and the receiver, so that you don’t need to disable your ESCs BEC. Just plug the Sport BEC in and fly.

Many ESC BEC ratings are inaccurate, because the capacity of the BEC goes down as the pack voltage increases. This means that your servos might not be getting enough power if you use a high voltage battery. The Sport BEC eliminates this problem and is capable of an output voltage of 3.5 amps when using up to an 8 cell battery. This is enough current to power up to 8 standard servos or 6 digital servos.

The Sport BEC can power almost every kind of model aircraft servo, including digital, standard, and micro servos. If you are using the Sport BEC with micro servos, be sure to set the voltage to 5 volts, or consult the servo owners manual. Some micro servos can be damaged by 6 volt power.

The Sport BEC has been designed to minimize radio interference, but we recommend that you place it at least 2 inches away from the receiver and antenna.

Use the Sport BEC to power the radio system of your nitro conversion plane, robot, or other RC vehicle. It also makes a great replacement for the low current BECs built into most ESCs.

The CellShield voltage cutoff is an advanced lithium ion and lithium polymer battery voltage cutoff for use with RC models.

Unlike other types of batteries, lithium packs can become damaged if the voltage of each cell drops below their specified minimum. The CellShield voltage cutoff prevents this from happening, by constantly sensing the the voltage of each cell. If any cells are in danger of being over discharged the CellShield triggers an immediate cutoff.

The CellShield voltage cutoff features a variable voltage cutoff, adjustable by a small dial on the back of the unit. The cutoff voltage can be varied from 2.5 volts to 3.5 volts, so you can use the CellShield with most lithium and lithium polymer batteries.

The CellShield voltage cutoff automatically detects how many cells your battery pack has. This lets the device know how to balance the pack during discharge, so that no cell gets over discharged. The cutoff voltage is also adjustable via a small dial on the back of the unit, so you can adjust the setting for different battery packs. The voltage cut off can be adjusted from 2.5 to 3.5 volts, which will protect most lithium and lithium polymer batteries.

Please note that if you use Thunderpower brand batteries, a 2 mm to 0.1 inch adapter is required, because the CellShield uses a different pin layout than Thunderpower connectors.

Use the CellShield voltage cutoff to protect your lithium polymer and lithium ion batteries in your RC models.

The K-DF-MINIHELI-ROTOR-2 is a set of two main rotors for your micro RC helis.

These rotors are able to fit any palm size mini two channel RC helicopter, just remove the broken rotors and then press the new ones on to the main shaft. Be careful while doing this, if you push or pull them too hard, you can damage your helicopter and break the rotors.

Each rotor is equipped with a pair of small weights on the bottom of the top section. These weights help stabilize the helicopter, so you will need to replace the main rotors if they are missing.

Use this set of main rotors to replace the rotors on your micro RC helicopters if they break. It is a good idea to buy the replacement rotor set ahead of time, so that you have them when you need them.

The K-DF-MINIHELI-TAILPROP-2 is a set of two upgraded replacement tail rotors for your micro RC helicopters.
The mini heli tail propellers are an improved version of the ones included with the micro RC helicopters. Spice up your mini heli by replacing the tail rotor with a red, yellow or blue tail prop! The tail propellers are made with a more flexible plastic, which lets them survive crashes better. The increased flexibility also makes it easier to replace the propellers.

The mini infrared helicopter tail propellers fit all of the micro RC helicopters available, including the PicooZ and it’s clones. They will also fit our popular Bladerunner Black Ghost micro RC helicopter.

You can use the tail props to replace any broken or damaged tail rotors for your micro RC helicopter. Just remove the old propeller, and push the new one on to the shaft.

The Multiplex EasyStar RTF is a simple 3 channel electric RC plane for beginners, intermediate, or RC aerial photography enthusiasts.

The MultiPlex Ez* RC airplane now sports a new color scheme. The wings and horizontal stabilizer are gray with orange decals, and the fuselage is still plain white. This color scheme is now incorperated in every Easystar that we sell.

The MultiPlex Easystar is a great RC plane for learning how to fly. It is constructed entirely out of durable foam, so repairs are easy. Just apply some super glue and hold the broken parts together. The wing has been specifically designed to self stabilize. This means that if you let go of the controls, the plane will return to a straight and level position.

A three channel radio system (elevator, rudder, and throttle) allows for a high degree of control. You can even do tricks like loops when you are confident with the aircraft.

Read this excellent thread on RCGroups.com discussing the Easystar RC airplane.

Use the Multiplex EasyStar RC plane to learn how to fly, or just have fun flying in a local park. You can buy a Multiplex Easy Star at RCtoys.com.

Every radio control aircraft (nitro and electric) uses an electronic system to control its flight. This article will explain how radio systems work.

Radio Control System Components

The radio system is what is responsible for moving the control surfaces of the RC aircraft. The individual components vary among different systems, but here is a list of the basic components which are common to all radio systems:

• RC Aircraft Transmitter - The transmitter sends the radio waves which control the RC aircraft. When the pilot moves a stick on the transmitter, the transmitter emits a series of radio signals which control the RC aircraft.
• RC Aircraft Receiver - The receiver is a device mounted inside the RC aircraft, which intercepts the radio signals sent by the transmitter. It then decodes these signals and moves the different control surfaces of the aircraft by telling the servos how to move.
• RC Aircraft Servos - Servos are small electric motors which move the control surfaces of the RC aircraft. Each servo consists of an electric motor, several gears, and a plastic case. Servos are mounted inside the fuselage of the RC aircraft, and attached to the various control surfaces via push rods (linkages, usually made of a plastic, wood, or flexible nylon rod).
• RC Aircraft Battery - Both the transmitter and the receiver need a power source. Normally, NiMh (Nickel Metal Hydride) or NiCd (Nickel Cadmium) batteries are used. Newer radio systems use lithium polymer batteries due to the increased capacity. Make sure that both the transmitter and receiver batteries are fully charged before flying.
• RC Aircraft Crystals - The transmitter and receiver use a crystal, which determines the frequency that they operate on. Radio control aircraft are limited to the 72Mhz (72 million cycles per second) band, but there are various sub frequencies within this main band. As long as RC aircraft are operating on different frequencies, the can be flown together. Newer radio systems use a 2.4 gigahertz freqency. The transmitter and receiver scan for an unused band, and then lock to that frequency. This eliminates the need for frequency control, and also prevents crashes caused by two transmitters using the same frequency.

Radio Control Functions

Each radio system uses a number of channels to control its servos. The term channel can refer to either the frequency that the radio system operates on or the number of control functions available. Usually, the number of channels equals the number of servos. Here is a picture showing the different control functions on a typical RC transmitter.

• Red - Antenna . The antenna is the long telescopic wire at the top of the transmitter. The radio signal that controls the RC aircraft is sent over this wire.
• Green - Left Control Stick. The left control stick controls the rudder and throttle. Moving the left control stick upwards increases the throttle, and moving it downwards decreases the throttle.
• Likewise, moving this control stick to the left will move the rudder to the left. Moving it to the right has the opposite effect.
• 
• Yellow - Right Control Stick. The right control stick controls the elevator and ailerons. Moving it to the left will move the left aileron up and the right aileron downwards. This will result in a roll to the left. Exactly the opposite occurs when this control stick is moved to the right. Pulling the right control stick downwards will cause the elevator to move upwards, causing the pitch of the aircraft to increase. Pushing the right control stick downwards will cause the aircraft to pitch downwards.
• Purple - Power Switch. Use the power switch to turn the transmitter on or off.
• Left Blue - The left blue switch on this transmitter lets the pilot teach a student using a buddy box. When this switch is held down, the student has control of the RC aircraft. As soon as the instructor senses trouble, he / she can release this switch and take control.
• Right Blue - This switch controls an extra channel, for dropping payloads, controlling landing gear, etc.

Your radio transmitter will come with a manual that clearly describes all of these functions. Refer to it when installing your radio system in your RC model aircraft.
