Many of you may be familiar with the Elite EX-5 Serial Bus & Servo Channel Expander, but now we would like to introduce the EX-5 K. The EX-5 K offers all the same great features as the EX-5 (such as multiple protocol support, telemetry, gyro-stabilized servo outputs, and more) but comes in an easier-to-install design. All inputs are encased inside a sturdy plastic housing, complete with a pre-installed installation bracket.
Specifications and Features – Supported Protocols: Jeti EX, Multiplex M-LINK, Graupner HoTT, Futaba S.Bus/S.Bus2 – Small dimensions and high current throughput via the integrated MR30 power connectors. – Telemetry (RC system dependent): Temperature, Voltage, G-Force (+/-30G), Attitude (Roll/Pitch/Yaw). – Gyro-stabilized servo outputs, EX Bus, SRXL16ch. or S.Bus. – Flight stabilization offering 3 configurable flight modes (Manual/Acro/Horizon). – Automatic detection of serial data/telemetry after startup. – Configuration through the transmitter or external terminal (JETIBOX/SMART-BOX). – Firmware updates via USB interface.
Introducing the Elite Voltario T70. Like the Voltario T60, the T70is a high performance, digital dual redundant battery switch with advanced telemetry features and touch switch functionality. It combines a backup battery charging circuit and telemetry functionality in a single device. The T70 however, offers additional expander ports that are not provided by the T60. The T70 is offered in two versions depending upon your set up. One option supports dual batteries, the other supports ESC/battery combinations.
Specifications and Features
Intelligent dual battery backer/multiplexer with configurable voltage switchover threshold.
Touch switch function (included) or optional mechanical, sliding or wireless (R3/RSW) options.
With So Many Great Options – There is Bound to Be One For You!
Introducing new servos from KST!
Servos from KST Technology offer ultra-efficient brushless motors, steel gear trains, aluminum case, low current consumption and constant output power. They are the perfect match for almost any high performance or racer pilot. Operational voltage: 4.8V – 8.4V
KST Technology servos utilize mini 25 tooth (Futaba) output spline for maximum compatibility with the large variety of aftermarket control horns.
Let’s see what is new! Check out the line of KST Servos HERE.
In the last Flight School blog we learned about how we use “radio control” in radio control flight, but just what are we “controlling”? In this blog we will dive a bit deeper into the common control surfaces of fixed wing aircraft.
A control surface is a part of an airplanes flying surface (wing or tail), typically hinged, that is moveable1. Movement of the control surfaces cause the airplane to react in a particular manner based on the movement. This movement is known as deflection or throw1. The four common control surfaces are ailerons, flaps, rudder, and elevator.
They main movements of an airplane are Roll, Yaw, and Pitch.
Ailerons are located on the outermost part of the trailing edge on your wings. The ailerons control the roll of your airplane and work opposite of each other. When one aileron goes up, the other goes down, resulting in the airplane the wing loosing lift on one side (the aileron that went up) and gaining lift on the other (the aileron that went down). Not all airplanes have ailerons. Those that do not, will rely more on rudder and the angle of the wing (dihedral) to roll1.
Ailerons are found on the outermost part of the wing, but some airplanes have an additional control surface between the fuselage and the aileron1 called flaps. Flaps are meant to help an airplane get more lift or reduce speed, depending at what time they are engaged and to what extent. Like ailerons, flaps can be found on the trailing edge of the wing, but unlike ailerons they move together. Moving together allows them to function without altering the planes “roll attitude”1 . Attitude is described as the aircraft’s “orientation relative to the horzion”2 . Roll, pitch, and yaw all effect the airplanes attitude. There are different types of flaps that work in slightly different ways. The types include conventional, split, slotted, and fowler3. Split flaps – where the top of the flap doesn’t move but the bottom swings down – are popular with warbird aircraft. You can read more about the different types of flaps here.
Rudder is the hinged surface on the vertical stabilizer1 . The vertical stabilizer is the part of the tail that “keeps the airplane lined up with its direction of motion”5 . When you move the rudder, you change the yaw of the plane, which “makes the nose of the airplane point to the left or right”1. The use of your rudder is very important control when taxiing, taking off, or landing. When left rudder is engaged, the plane will go to the left – right rudder will direct it the aircraft right.
The last control surface that I will be covering are the elevators. One of the most important control surfaces, the elevators are responsible for controlling the pitch of the airplane. Pitch is the up or downward movement of the aircraft. The elevators are located on the horizontal stabilizer – the part of the tail that “keeps the airplane aligned with its direction of motion”5. Elevators move the same direction of the nose, so when the elevators are deflected up, the nose goes up and vice versa. Elevators will also effect the airspeed of the plane based on how and when they are engaged1.
