Testing and Learning; Waypoints and AutoPilot


This week I tested the Ardupilot's waypoint and autopilot functionality, and it had mixed results, which I now have identified as total user error. Go figure. :)


The waypoint feature performed as good as it could, it struggled a bit as my GPS module only has about a 25% view of the sky, which is clearly not ideal. I'm working now on a better mounting location that will give it 100% view.


Why do I think it's the GPS mounting…

Interested in assisting Aerosight on a Discovery Channel series?

Good day everyone,


Today I was contacted by some producers who do a ton of work making programs for the Discovery Channel. They do the shows like military channel etc.


Today we discussed Aerosight's availability to assist in a new show that will follow the UAS operators tracking down lost people in a SAR type of mission. The show will be a series, paid, and in and outside the USA. The involved companies/persons will need their own equipment that is capable of…

Headlights when motors armed.

I added very bright LED headlights to the quad a while back a) to freak the locals out at night and b) to help with orientation when the quad is far away. These are 12V LEDs and run straight of the 3S lipo. All was well....

One thing I don't like much is the rather small and dim SMD LED to tell me when the motors are armed. Mostly…

APM SketchUp Model

I haven't found a 3D model of APM for download anywhere. So I made it on SketchUp. I used Eagle Up to generate the boards from eagle. It's still missing some parts but the connectors are there, fell free to help complete the board.


The models for the MediaTek GPS, and Xbee, are…

Quad vs Quad GPS Position Hold Combat!

Here's a fun competition between a KK navboard quad and one flying the Ardupirates version of the ArduCopter code. They're set to the same GPS position hold target and then, well, watch the video....Very dramatic ending!

Ducted Fan Tricopter

I have been experimenting with a ducted fan tricopter.  It flys much better then I thought it would, flying time is about 5 minutes on a 4 cell 3300mah battery.  It is a blast to…

How to NOT get grounded by FAA...

Hello all!

Just a suggestion for those who got affected by the FAA enforcement policies against UAVs used for aerial Photography in LA area, and even if you are not affected by this you can use our telescopic masts that go up to 60 ft high.


No crashes, no more "mayday mayday, my batteries are dying", no police asking questions, no repairs and no parts to be ordered for replacement......

Most of my customers and even myself are…

Experiment with Momentum Cancelling Code

Experimental Momentum Cancelling Turned On

In the above flight, Arducopter 2.3 is being used with stock PID, basically no tuning at all.  The INSTANT_PWM, is enabled.  The propellers are not balanced, and nicked up, from rough flying.  The framed use is my…

AEROGIS Image processing services - not only for UAV images

Hi UAV operators,

I would like to introduce GISCATs UAV / MAV aerial image processing service - AEROGIS

AEROGIS services convert your digital metric or non-metric aerial photos into sophisticated value-added digital products like ortho-mosaic images, 3D-surface models and high quality maps. AEROGIS has already successfully processed great numbers of images covering a broad…

Arducopter 2.3 tuning Stab_P for Nav video scenarios

Hello again everybody,

Round two of "organized testing" I decided to keep my Nav settings from last time(see previous blog post) and only play around with the Stab PID parameters to see what kind of effect they have on Loiter. I started off by increasing my Stab_P from 3.5 to 5, then to 6, and finally to 7. I noticed a significant improvement…
