Quick Answer: What Does Expo Mean In RC Planes?

How many channels does a RC car have?

two channelsNormally an RC car requires two channels, one for steering (ch1) and one for throttle (ch2).

However, in most cases, controllers have 3 or 4 channels..

How do you reverse a servo on a DX6i?

Press and hold the roller above the LCD display on the DX6i for three seconds to bring up the SETUP list. Rotate the roller to scroll down the SETUP list, and highlight the REVERSE box. Press the roller to select REVERSE. Rotate the roller to scroll down the REVERSE list, and highlight RUDD for rudder.

How do RC transmitters and receivers work?

The transmitter enables control through radio waves and the receiver activates the motors. When we press a button on the transmitter to make the RC toy go forward or backward, a pair of electrical contacts touch. Receiver identifies signals, sends it to circuit.

How can I control my remote control car with my phone?

To control the car, we will use an App that I developed, using the MIT AppInventor 2: “MJRoBot BT Remote Control”. The app can be downloaded for free from the Google store via the link: App: MJRoBot BT Remote Control.

What is exponential in RC planes?

Exponential allows you to program just how much an airplane’s control surface (elevator for example) moves when you move the transmitter stick. For example, on my scale aerobatic airplanes I have the expo set to move the elevator hardly at all when I first move the transmitter stick from neutral.

What does dual rate mean RC?

“Dual Rates” refer to altering the rate of servo travel for a control surface on R/C aircraft (e.g. Ailerons, Elevator, and sometimes Rudder). Dual Rates consist of Low Rates and High Rates.

Can 2 remote control cars same frequency?

Most RC toy manufacturers make versions of each model for both frequency ranges (27 MHz and 49 MHz). That way, you can operate two of the same model simultaneously, for racing or playing together, without having to deal with interference between the two transmitters.

What is dual rate and expo?

Typically 25-40% expo on control surfaces is typical for beginners. Dual (multi) rates: Dual, or multiple, rates controls the total deflection of the control surface. On most of my models I setup 3 rates. This is mostly due to using a Taranis radio where most all the switches are 3 position.

Will any 2.4 Ghz controller work?

In general, no. There’s little or no interchangability between brands (at the moment) with 2.4 Ghz equipment. Nope, completely manufacturer specific. JR & Spectrum are the same so they are cross compatible.

What RC transmitter should I buy?

For a beginner, a 6 channel transmitter like the Spectrum DX-6i would be a great long term investment. … If you are more advanced, an 8 channel transmitter like the Futaba T8J or a 9 channel model like the Hi-Tec Aurora 9 is a great buy. Another GREAT transmitter you should check out is the FrSky Taranis X9D.

What are flight modes Spektrum?

Flight Modes let us assign specific channels to this system, so the transmitter remembers trim changes made to those channels whenever that model is selected. Any future trim changes are also remembered when the transmitter is turned off or a different model is selected.

What does trim mean on RC cars?

Steering trim is the way the radio helps the car track perfectly straight and is crucial especially on straightaways or even speed runs. Every radio these days has a trim knob/switch to adjust the way your RC vehicle is tracking.

How do I set my throttle trim on my RC car?

Find the throttle adjustment knob on your RC transmitter. Adjust the nob clockwise to increase the throttle speed. Adjust the nob counter clockwise to decrease the throttle speed. Play with the throttle until the vehicle accelerates in a realistic manner.

What is Throttle dual rate?

Dual Rate Adjustment It adjusts the ‘throw’ of the input, meaning the entire travel of the steering/throttle inputs are in use but they are scaled down. With the dual rate turned right down on the throttle, ‘hammering the gas’ will result in the transmitter telling the ESC to go say 30% throttle.

How fast is 27 MHz in mph?

Flies up to 30 MPH and over 20 stories with a flight range of over 300 feet. Ready to Run – Includes XPV Battery System that also charges USB devices … 27 MHz Manufacturer recommended age … they don’t fly as fast, and they must be hand-launched.
