Thanks to Bill AKA I Love Robotics, the National Recreation Flyers has its own domain name!
My vote goes to Bill as…Continue
Here is a quick preview of my next frame for ArduCopterMega. That is my Tri-Copter frame with the old landing skids (t-rex 500) from first quad frame. I just need to rewire ECS :) And its ready to fly.
Arms are 15X15mm 1mm thick and 500mm long.

Now, development of an actuator for Marcy 1. After all that static testing against gravity, the restoring force from the air wasn't enough to get the flap to straighten. She just cocked up like a wing at 45 deg.
Since air exerts less force than gravity, maybe actuating the entire wing with some kind of spring as a…
Status of Project:
Hardware Available and in public roadmap.Continue
If you are familiar with the FIRST organization, you know that its filled with great students, mentors and of course robots. I have infact read rumors of DIY drones working with FIRST to develop a quad competition (awesome!). Lots of events around the country are happening…Continue
A digital control system model of the pixhawk quadrotor was constructed in scicoslab along with a continuous model of the quadrotor dynamics (the visual model is an arducopter). The user can input the guidance commands to the autopilot through sliders. As the video shows, the yaw response it not optimal, which also happens in the actual system. Using the mavsim Scicoslab toolbox (https://github.com/openmav/mavsim/) ,…Continue
Hey all, over the past two years I've spent a lot of time browsing the DIYdrones website, unfortunantley not really posting anything, but im ready to finally get back into it. The progress that has been made in these two years is absolutely astonishing, and I plan on getting wet real fast.
I'm now in college now,…
The Arduino/Arducopter is a notable project . Actually the ratio price/quality is very good.
But looking at the frame it is clear that some points can be improved: motor mounts, landing ski and GPS holder.…Continue
The National CBO "National Recreational Flyers" now has free membership, download, trim and laminate your membership card today.
Also posted on the site are the Safety Rules in a PDF file suitable for downloading, laminating and posting at your flying…Continue
I worked together with LanyuHobby (RC airplane manufacture) to make a good platform for FPV/UAV flying.

I decided to implement an on-board declination calculator based on geographic location and I'd love to get some feedback. It takes up about 1400…Continue
Last month Chris and I were interviewed by Carrie Kahn from NPR West regarding drone use.
The report is unfortunately a bit of an anti climax (see link). I really tried very hard to present our community as progressive, safety aware innovators and the main theme of the…Continue
More pictures from the DIY Drones factory in San Diego. I mentioned before how important testing and QA is. The above picture shows how it's done: each product has a dedicated test jig, with spring-mounted pogo pins and a special…Continue
Good article from O'Reilly Radar. It's worth reading it all, but here's the nut:
The core issue is that GPS technology has been built into many crucial infrastructure applications, from transportation systems…
A lot has changed since my last photo tour of the DIY Drones San Diego factory. We've moved next door to space more than twice as large…Continue
This is the new folding frame Project I am working on.
Can anyone tell me if it´s possible to control the eight counter rotating motors with…Continue
By popular demand, ArduPilot Mega is now available as an all-in-one kit for $250. It includes everything you need for a functioning autopilot with GPS, even including RC cables.
We'll soon be offering wireless…Continue
