RunCam 3 - User Feedback

Recently bought this RunCam 3 box style HD camera for FPV and regular use. I also 3D printed a cover for it. Thanks for Barspin who contribute the 3d design. Here is the link to the 3D Design. Here is the RunCam 3 manual.

So far, I feel the picture quality is great or even better than my old GoPro 3. The cube size is perfect for putting anywhere I want to. For FPV, it is easy to wire the cam to video transmitter.

Auto Pilot RC Drone - ArduPilot APM 2.8

ArduPilot APM 2.8 setup:
  1. Download Mission Planner from here. Mission Planner documentation can be found here.
  2. Connect the ArduPilot APM to the computer via USB cable.
  3. Open Mission Planner, select the comm port then click "Connect".
  4. If not working, go to Device Manager to update driver using driver under Mission Planner folder.
  5. Download firmware to the board (don't "Connect" to mission planner). Mission planner will automatically download the firmware from internet and upload the firmware to the board.
  6. See the wiring connections between the board and the other hardware. Here.
  7. Calibrate the board, radio and ESC. I skipped the ESC calibration. 
  8. Select flight mode. Flight mode descriptions are in here.

Scratch Built RC Plane -Subsonic Drone v2 Plane Design

Subsonic Drone build logs:
Click here to see the Subsonic Drone v1. Also see the Micro Drone V3 for all the overall dimensions.

I designed the plane in SketchUp which is (formerly Google Sketchup) a 3D modeling computer program for a wide range of drawing applications such as architectural, interior design, landscape architecture, civil and mechanical engineering, film, and video game design—and available in a freeware version, SketchUp Make.





Completed! Getting ready to maiden. 


Let's start building it!

Done Registration - for the USA


According to FAA, people who previously operated their UAS must register by February 19, 2016. People who do not register could face civil and criminal penalties.

I don't like it but better be safe than sorry.

Here are the links to FAA for Done or Unmanned Aircraft Systems (UAS) registration.

https://www.faa.gov/uas/registration/

FAQs for the registration - https://www.faa.gov/uas/registration/faqs/

Here are some information about general rules for operating model aircraft.

Drone - 250 Quadcopter Emax Nighthawk QAV

First, this QAV250 Quadcopter frame is not from Emax nor NightHawk . I used those names in the title is because people can search to this easier. I bought this from AliExpress. Here is the link to it and search for QAV 250.

I had the maiden flight, and it performed very well. Both the motors and ESCs got a little warm but acceptable. Not sure it was because of the props that drew too much current. Overall I am happy with the performance and the plastic motors.

To see how I made the Micro FPV setup click here.

  • Height: 170mm
  • Weight: 425g (frame only)
  • Motor Mount Bolt Holes: 16~19~25mm
