I’ve been building and flying electric R/C model airplanes since 1994, starting with an electric conversion of a Goldberg Gentle Lady sailplane.
As an inveterate tinkerer, I’ve designed and built a lot of my own support equipment, such as electronic speed controls and NiCd chargers, much of which is documented here. From 1997 to 2004, I wrote for Quiet Flyer magazine, and many of those articles are found below too. I’m also the author of MotoCalc, the popular program for choosing and optimizing electric model airplane power systems.

The Battery Eliminator Circuit. December 1, 2003 for QuietFlyer Magazine The Battery Eliminator Circuit, or BEC, is one of the tools at our disposal to reduce weight in our electric models. A typical four-cell 600mAh nickel cadmium (NiCd) battery supplied with most radio systems weighs about 3.3 oz (94 g), a significant fraction of the weight of a typical beginner’s electric model (such as a Great Planes ElectriCub or Spectra). Lighter batteries are available, but with the trend towards even smaller and lighter models, even a 1.5 to 2 oz (43 to 57 g) battery is too much to carry. The model will still fly, but it’s flight characteristics will be compromised. The BEC lets us eliminate the receiver battery, using the motor battery to provide power to the radio system instead. How it Works Typically, the BEC is part of electronic speed control (ESC) which acts as the motor’s throttle. Figure 1. The BEC supplies power to the receiver through the same lead from which it gets the throttle signal.

Model Flying, the online home of RCM&E Magazine. Purchase - arducopter - Arduino-based autopilot for mulitrotor craft, from quadcopters to traditional helis. Get it! If you're just starting, we recommend you get a full kit. If you're handy with a soldering iron and are looking for a fun assembly project, get an unassembled version. If you just want something that will fly right out of the box, get a ready-to-fly (fully assembled) one (you only need to add a battery and RC-gear of your choice). Quadcopters: Hexacopters: Quadcopters 3D Robotics kit ($449) jDrones Original ArduCopter kit ($549) | jDrones Simplex Quad kit ($440) Hexacopters 3D Robotics kit ($549) jDrones original kit ($749) | jDrones Simplex Hexa kit ($540) You'll need these components: APM 2.5: Available fully assembled with GPS and power supply/sensor from 3D Robotics for $179.
Optional: Telemetry kit: 900Mhz 3DR radio set for the US or 433Mhz 3DR radio set for Europe and other markets where 900Mhz is not allowed. If you don't already have batteries/chargers and RC gear, here are some suggestions: LiPo battery and charger: You can read basic info about LiPo batteries here. DIY Drones. Intro to Model Airplane Autopilot!!! Hi All! I am twenty years old. I picked up my arduino for the first time this Christmas, and I've been keeping busy on my arduino applications so that I can bring you this instructable. I hope that it helps!!! The purpose of this project was to build a stepping stone from remote controlled flight to completely autonomous flight.
This initially seemed like a daunting process, but by breaking it up it becomes manageable. You can buy a complete platform for developing your own autonomous flyer as well as download a complete code!!! I had two primary objectives when beginning this project: 1) Achieve sustained level flight using our autopilot program 2) Ability to switch between radio controlled and arduino controlled flight I strongly recommend that you already have some experience flying RC airplanes, otherwise you should look for your own plane and get some stick time. If these things are new to you, I hope my instructable is helpful.
