Great day of ArduPilot 2.5 testing. Bugs caught, some fixed

Jason Short and I had a great day of flight testing yesterday after the rains cleared in Point Richmond, across the Bay from San Francisco. We were testing the 2.5 code on a range of different hardware (RC systems, ESCs, GPSs and airframes) to catch incompatibilities. The good news is that we found lots of them! (that's the bad news, too).


These are the bugs found:

UAV Flight from Vieques to Puerto Rico!

Hello Everyone,

I am an aerospace engineering Ph.d student at a university in New York and also the teaching assistant for an undergraduate course in aircraft design which will be partly taught in Puerto Rico. One of the main objectives for the course is that the studens have to design, document, and build radio control airplanes following traditional design formulae. Having following this community for a while, I proposed to the…

Fried Video Transmitter, minor set-back :-(









Lesson learned: don't try to wire small circuitry at 11pm at night. Last night I received a small CMOS video camera + transmitter combo (2.4 ghz LTS wireless camera) and put it on my E-Flight Blade MSR. I was actually able to…

ArduIMU Quadcopter part II (mini)

Hi all,
I have finished my second quadcopter with ArduIMU. This time is a "mini" version with only 28cm from rotor to rotor and has the new Jordi´s magnetometer integrated!.
This tiny machine is fantastic, with a great stability. Look at the hands-off part of the video inside house!!
Very funny :-)…

Updates-- trying to control a micro indoor helicopter with PC and transmit wireless video

I just bought a wireless camera for my micro heli E-Flight Blade MSR. More on this below....



I took a few weeks to digest everyone's suggestions, and I think I now have a better grasp on my project and where I should take it. For a while I couldn't quite understand why everyone was telling me that I should loose the complexity and stick to simple designs, but then I remembered… Continue

RE: The Long Tail as applied to Atoms (the new bytes)

Struck as I was by Chris's report in The Long Tail that sales of obscure items were outpacing sales of "hits", it seems trivial to conclude that economic growth - should we be so lucky - would not only come from "small business" generally, but from products for small markets in particular. While the the Long Tail explanation - that distribution and advertising costs are low - holds for bytes (songs, software, "apps", search, etc.… Continue

Day 1: the Noomie [read "New Me"] LOL

Ok, SO...Thanks to Gary for flipping the switch in my slogging grey matter...

All future Blog Posts will be about my search and acquisition of a trainer that is suitable for me. There will be no questions (from me) here...

I'm off to the forums now...

Starting over...maybe.

I have stopped my Predator build and sold most of my gear, for now. Doing more research and looking to get a good basic trainer (.40 or .60 class) not sure if it will be nitro or electric yet. A 2.4 gHz radio system. And put in some simple build time and then get experience flying.



The Predator became a stalled frustrating build because I was trying too much at once, without any experience to back myself up.



I hope to get a system with at least…
