Expo duo provides the benefits of exponential control to hobbyists that do not have sophisticated radios with built in exponential functionality. Expo duo can decrease the sensitivity around the center position, making it easier for new flyers to control their models, or it can increase sensitivity for experienced users who want to do aerial acrobatics. Expo duo works by intercepting servo pulses from your receiver, processing them with a mathematical algorithm, then outputting new servo pulses according to your desired response. You can set the desired sensitivity level with the onboard dial. The result is that small stick movements around the center point will cause smaller, or larger movements on the servos. As a bonus feature, Expo duo will reject invalid servo pulses, which will filter out many glitches. Expo duo works great with Blade CX/Lama 2 helicopters, flying wings and other dual servo systems. Expo duo can also be used to add exponential control to a single servo - just leave the other channel unconnected.

The neodymium magnets motor and rotating case is a unique design which enable additional torque to be piped through the motor’s shaft. The motor can be used for mini Helis such as the ECO 8 Eolo and Corona. The outrunner motor spins with both the outer casing as well as the shaft creating a powerful yet efficient 3D motor system. Ships with a 5mm shaft.

Cyclon Heli motors have 50% less mass than a traditional internal rotor motor. The Mini Heli Punch weighs just 50 grams, but can power Align's T-REX 450 helis up to 3000 rpm. Cyclon Heli motors are perfect for all maneuvers, from hovering to extreme 3D, for a wide variety of models. Mini Heli Punch is suitable for the Align T-Rex 450, Zoom 400, MX400, and other mini sized helis.

This is trully performance that fits in the palm of your hand!. The SL420 Micro is ideal for the pilot wanting an affordable gyro that offers serious performance. With a weight of only 12 grams, the SL420 Micro is ideal for models from the Micro Helis to larger glow powered machines. CSM has been working to improve gyro performance for the 3D pilot in several major areas and to break down some traditional trade-offs found with conventional Piezo technology. Based on the standard SL420 Smart Lock gyro, the new SL420 Micro offers all of the features and versatility found in the top of the line SL560 Micro, without the additional complexity and cost of the interface capability.

This Align Battery pack is used to power the electronics on full size Helis ( Servos, RX ). This eliminates the need for a BEC. Some do not like using a BEC as it uses the power of the main battery and reduced the overall flight time, this battery pack solves that issue. The battery is small and light so the extra weight is not a weighing factor.

The small and powerful AXI 2217/5H outrunner from Model Motors is specially designed for the T-Rex 450 and TT mini Titan size helis. Hardened steel Shaft have 3,17mm diameter and is supported by two large ball bearings which ensure very good mechanical stability. Extremely high efficiency and high load capacity for its weight class.

Venom's V40 Brushless Motor combined with the V-Series 45 amp Brushless ESC is a dynamite combination for your T-Rex, MX400 and other 400 / 450 size Helis. Powers systems with approx. 17 amps (Max Amps: 32). Max Voltage: 3S Lipo Battery Pack or 12.6 volts. Includes 3mm pre-installed connectors.

Complete Pro 410 motor with housing fan and screws. Designed for the Pro Piccolo but will also work for all other Piccolos. Will operate using the standard Piccolo board and Piccolo Pro board.

The coreless tail motor is incredibly efficient and will allow for both longer life of your tail system and higher output. For best performance use with the Wes Tech high frequency tail controller ( HH376 ). The DC 5-2

This motor was specifically designed for the advanced flyer that requires additional power for extreme aerobatics as well as fast forward flights. 3.2 mm shaft diameter.

Microprocessor-controlled digital speed controller for brushed motors. Designed for high current applications. The high frequency motor control ensures high efficiency of the speed controller and at the same time increases the life of the motor. The ESC also features an automatic engine-off balance as well as a secure start system.

This would be a duration and power combination motor for aerobatics and 3-D flying for the Logo 10 or Eco-8. Powerful Hacker B50-13L is one of the ultimate motors for the Eco-8 Motor has 5mm shaft and cooling fins ( Cooling fins can be removed ).

This motor will give you excessive flight time and is considered a very smooth setup for the Hornet. The motor runs cool and produces great results in both the FP and CP Hornets.

This is a power house of a motor. This is an excellent choice ( and some even consider it the BEST choice ) for the Zoom / Shogun / TREX and ARK Helicopters. It is designed to give the flyer plenty of power for aerobatic flying. Also works well on the Piccolo CP. The motor is a long casing motor.

A wonderful motor for mid size Helis such as the Logo 10 and ECO-8 and ECO-16. A very fast motor which will enable a mid size Heli to go ballistic and perform with sharp response and intense power when coupled with proper gearing per your machine.

This motor is the one to get for the ultimate in cyclic response. At over 2650 RPM per volt this motor will allow for a great responsive disk when used in a collective pitch setup. The 31S is probably the hottest motor for the Piccolo CP and Pro.

This motor is a good choice for general sport flying with the Piccolo Pro CP or FP. It will provide a good mix of performance and flight time. At 2500 RPMs per volt this motor is the perfect all-in-one brushless solution.

Robust and highly reliable rotor head with absolutely precise tracking during hard 3D will easily withstand forces even during high RPM. Classical O-rubber dampeners enable to adjust the head stiffness. The head includes one piece connection between the blade grips and top quality thrust bearings.
