Indoor Micro FPV Copter

thingiverse

A micro FPV quad copter based on the Scisky brushed flight controller board. Perfect for beginner FPV and indoor practice, this board will run Cleanflight allowing you to configure it to your hearts content. The camera is easily removable, just unplug it and remove the elastic band holding it on. Then you can also practice your acro tricks indoors with a small, light copter that wont do much damage to things it hits, or itself when you crash. Design considerations: All electronics can be removed without desoldering if you break the frame (though so far it is proving to be fairly robust) Camera can be quickly and easily removed Camera can be either held on with a zip tie, or an elastic band which means that it a crash it just gets dislodged, rather than damaging the antenna.

Hardware Required You'll need: Scisky Brushed Flight Controller: http://www.radioc.co.uk/Micro-scisky-32bit-brushed-fc-p/3119.htm Motors: http://www.dronejunkie.co.uk/product/cl-0820-coreless-motor/ Battery: http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=37566 Camera: http://www.banggood.com/Eachine-EF-01-AIO-5_8G-40CH-25MW-VTX-800TVL-13-Cmos-FPV-Camera-p-1064301.html Some Hubsan propellers Optionally (if you have a Spektrum transmitter that doesn't support DSM2 - i.e. a European one): Lemon RX receiver: http://www.ebay.co.uk/itm/Lemon-RX-DSMX-Satellite-Receiver-UK-Same-Day-Shipping-Spektrum-Compatible-/262538941725 Build Guide There is a good guide to set up here: http://community.micro-motor-warehouse.com/t/how-to-set-up-scisky-fc-step-by-step/1224 The motors connect to the closest motor connection on the board, be sure to get the motor rotations correct based on the colour of their wires. You should be able to wrap the wires around the arms before inserting the motors into the motor holders. You might want to add a small blob of glue to stop the motors sliding up and down in their mounts. Optional Lemon RX DSMX Receiver As I discovered if you are in the EU and have a recent Spektrum DSMX/DSM2 transmitter then it wont bind with this flight controller because DSM2 has been "banned" in Europe so all the DSMX/DSM2 transmitters are actually just DSMX. The Scisky board however is DSM2 only and so wont bind. To overcome this get a Lemon RX DSMX satellite from the link above, remove the case an connect it to your flight controller board as per the instructions in this thread http://community.micro-motor-warehouse.com/t/fc-scisky-dsmx-satellite-mod/522 The key to getting the Lemon RX to bind is to use the Cleanflight cli to "set spektrum_sat_bind = 9" (or maybe 7, I forget which worked for me). Details in the above forum post. I used some liquid electrical tape to secure the 3.3V connection on the main board. Hot glue would also work well. I then wrapped mine in heatshrink to stop it from shorting with anything on the main flight controller board. Lemon RX mod connected to Serial connector and taking power from a pad on the board. Lemon RX receiver wrapped in heat shrink and packed on top of the Scisky flight controller board. The two antenna poke out of the front and the back of the copter. First flight video
