S500 Quadcopter Build

A Project page for my S500 frame and APM2.6 Quadcopter build, with WiFi firmware loading via ESP8266

A place to document the build of my first quadcopter using the S500 frame, which is based heavily on the DJI F450

This is just a standard ArduPilot Mega 2.6 multirotor build with the addition of an ESP8266 module for wireless loading of firmware and streaming data during calibration processes. The end result will be a fully autonomous quadcopter running of APM2.6 using the S500 frame.

The S500 frame is essentially a clone of the DJI F450 flamewheel with a few upgrades. The arms have been updated to have more screws and points of attachement to the PCB frame, and the arms have carbon fiber rods running through the. Overall the S500 is a massive improvement over the F450 as far as rigidity and stability are concerned. These frames also come in a few colors, have cheap parts (replacement after crashing), and are not very expensive at all. You can also get these frames through HobbyKing. Its worth noting that the S500 and F450 flamewheel are both about the same size and the Phantom series quads, so you can get an idea of how big it is from that.

  • Mini Update

    So I found a solution to one of my problems with the project. Initially I was going to mount the display on my TGY-i10 radio but then I was like goggles are cooler. Off the shelf solutions are pricey so I was gonna design my own and 3D print them. Thanks to openess and sharing I won't have to:

    Everything right there to print goggles for the 7 inch screen I have wired up and working with the 5.8GHZ radio. Now just gotta see if it will fit on my Rep1 style 3D printer bed.

    Stay tuned.

    Hey so this project hasn't been abandoned it was just put on the backburner because I cheaped out and bought everything from china, turns of the PCB was garbage, so I bought an authentic one from hobbyking. At some point I'm going to completely disassmble my near finished build and resolder everything, hoping to get aerial in the next two months or so depending on how much time I have to dedicate to it. Stay tuned!

  • FPV Screen Test

    AVR11/11/2015 at 01:13 3 comments

    Last week I soldered up and tested my FPV screen. This screen gives me the video feed with telemetry data overlayed from the quadcopter's camera. The transmitter and receiver are the generic PAL 5.8GHZ analog set you can find on ebay or alibaba. This test was merely just a power on test, to test the screen wiring, in a later post I will show the transmitter and camera working.

    Back cover of the screen, 5.8GHZ PAL receiver attached with command strips, eventually going to make a 3D printed casing to graft to the back of the screen for mounting the PCB of the receiver sans case.

    Second hole drilled in place next to stock video cable hole. The second hole is for the power cable that will connect to a battery, the cable is long so the battery can be placed in my back pocket.

    All put back together and powered on. Note red LED on 5.8GHZ receiver.

    Bottom view, showing wiring from radio receiver into screen, and power cable.

    Default screen when no signal is detected on the input. The screen has two analog inputs switchable by the buttons on the front or included remote.

    Thats all for the screen test, radio and camera test in next update.

  • In the Sky Soon

    So there aren't too many updates or logs for this project mostly because it took about a day to assemble the damn thing a second day to correct some of the soldering and then placed on the backburner while I worked on other things. Anyways I plan on getting the props balanced when my balancing tool comes in this week and hope to be in the sky by the end of the week.
