However, receivers and servos of modern electric power (EP) rc airplanes don't usually have their own battery pack because their power is taken directly from the motor battery pack via what's known as a BEC - more on that later. The basic components of a typical radio control system are the transmitter, receiver and servos.īattery packs, or individual cells, are needed to power all the components. But with that said, the fundamental operating information outlined in this article covers both types. Incidentally, this page was originally written before the advent of 2.4GHz (gigahertz) rc systems, so it mainly talks about the traditional MHz (megahertz) radio control gear. Understanding the basics of radio control gear and how it makes your rc plane do what you want it to (most of the time!), is important if you want to get the most out of your new hobby. **RC BEGINNER'S PLANE GUIDE FLASH SALE - JUST $10!!** Radio Control Gear Explained Low RX current of 10.3 mA, 200 nA register retention.įully integrated synthesizer with a resolution of 61 Hz.įSK, GFSK, MSK, GMSK, LoRaTM and OOK modulation.īuilt-in bit synchronizer for clock recovery.Īutomatic RF Sense and CAD with ultra-fast AFC.īuilt-in temperature sensor and low battery indicator.Home Site search Site Map About Me Contact Me Site FAQ Privacy/Cookie Info Testimonials <- natural consequence of power and link budgetīullet-proof front end: IIP3 = -12.5 dBm.

Adds LORA to RasPi and can add GPS functionality with GPS input to RasPi serial port. Raspberry Pi LORA-GPS module - $35 Digikey. Seeed Studio module from Digikey - $US7.91/1 in stock (!) There are numerous on web Raspberry Pi + LORA related pages. ICs are available but modules offer vastly better cost-benefit. eg -148 dBm RX levels at 100 mW tx power (!). LORA utilises 'spread spectrum' techniques to achieve astounding-but-true real-world link budgets of typically 168 dB. Ranges of "over 10km in rural areas" are cited (antennae unspecified) but there is every reason to expect that this range can be exceeded in ground to air operation with 'sensible' antennae. Operation with external antennas at 2.4 GHz can achieve ranges of many km - especially in ground to aerial operation.īut, look at LORA ("Long Range") modules which should easily meet your needs. WiFi should be able to work well for your application.ĮSP8266, ESP32 and their kin should be suitable.
#Rc plane transmitter and receiver how to#
I searched around for things like "raspberry pi rc receiver" and "USB rc receiver" but apart from some tips on how to turn your raspi into a transmitter to an rc car (for which I don't know the range), I can't find anything about longer range receivers for the pi, or rc transmitters to attach to my laptop with which I can just send and receive arbitrary json.ĭoes anybody know whether there are any simple modules which I can attach to my raspi and laptop to send json with this rc technology to and from the pi over a range of at least 200 meters? All tips are welcome! I see plenty of rc receivers around to buy, but they all work with a number of channels, instead of a data link over which you can send arbitrary data/json. Plus the range of the wifi is not very good (I tested it outside and it comes to about 50 meters).Ĭonventional rc transmitters and receivers have way better ranges (up to 1000 meters) than my wifi from the router does, so I'm wondering how I can leverage that technology. I got it working over wifi, but that means I need to take my router outside when I go flying. I want to be able to send commands in json from my laptop to the Raspberry Pi in the plane. I've got a Raspberry Pi with an IMU and a pitot tube in the plane and it can now control the servos of the plane. I've got a pet project in which I'm trying to write/build a self learning autopilot for my rc plane.
