Logging airspeed on 2.74 onwards...?

Started this discussion. Last reply by Andrew Rabbitt Feb 6, 2014. 2 Replies

Does anyone know which parameter group I can find airspeed to log (passively). I have looked in CTUN and NTUN but neither appear to have this listed. Any hints and tips here...?

APM in a 250

Started this discussion. Last reply by Rob_Lefebvre Jan 20, 2014. 8 Replies

The crazy man in me is trying to stuff an APM into a cheapie HK250GT as a method to waste an inordinate amount of time. (and likely also money) It is a great lesson in weight reduction and…Continue

Arduino/Ardupilot IDE "hangs" whilst attempting to complie

Started this discussion. Last reply by Andrew Rabbitt Aug 9, 2013. 1 Reply

I'm trying to compile a (very) subtly modified version of Arduplane 2.74b using the IDE downloaded from the Arduplane website (1.0.3) but it hangs when I try to compile.  Actually, it doesn't hang…Continue

Mapping servo neutral and end points...?

Started this discussion. Last reply by SKYBORNE May 6, 2016. 6 Replies

Does anyone know any way of mapping the servo mid and end points that APM uses?I have modified elevons on my Skyfun which, unfortunately, have a limited down travel.  If the elevon servo forces it…Continue

Please tell us a bit about your UAV interest
Inspired by press articles earlier this year on near-space ballooning, I would like to one day send a UAV glider aloft for a positionable return to land. I'm sure others have similar ideas.

Climb-Glide: Improving the range of fixed-wing, electric UAVs

Posted on September 18, 2016 at 12:56am 21 Comments

A climb-glide routine can potentially yield a useful increase in range compared with the same airframe/propeller/motor combination operating straight-and-level at best range speed point or best endurance point respectively.

Let me explain briefly with graphs of the results how I have…

Exploring the secrets of flying wing design with CFD.

Posted on July 28, 2015 at 9:36pm 44 Comments

The flying wing design I have been working on for some time now has been slowly evolving as I have learned more about aerodynamics and expanded my skill set with modelling tools of various forms.  I have recently completely re-surfaced my design with new aerofoil sections and better, more consistent surface…

Wing lift distribution presentation

Posted on March 27, 2015 at 12:50am 11 Comments

A very interesting and thought provoking explanation of why the conventional wisdom of elliptical lift distribution needs rethinking.  Interesting for lovers of fixed-wing but also might be applicable for propellers and rotors...?

Digital flight control research from the '80s

I tripped over this on my suggested links and thought it might be of interest to the DIYD crowd.  Fascinating to see an original Macintosh being used as a ground station!

Andrew - Thank you for commenting on my BLOG DIY Passive Gimbal.

How about whacking four free-spinning electric motors on it? One flanking each axis? Just so it is balanced. Would they cancel eachother out? Or would making them spin CW / CCW to each other be better?

Hello Andrew! Thanks for the support, and offer. I will definitely keep you in mind if anything comes up. The Idea behind the albatross is open. By this I mean, it has specific goals and design elements, however in the long run I would truly like innovations to be customer based. For instance, If customers started laser cutting their own internal storage shelves/formers, and/or other mods, such as a dome/nose adapter.

If the Pro version every comes to be, I will definitely be needing some specific arts, such as retaining clamps and rings for easy quick-release style components.

Hi Andrew

I have seen your pic of the qx 100 teardown. I want to teardown my qx 10 but before I do may I ask do you think it is possible to soldier a connection on where the shutter button is (on the flexible printed circuit) and then use pixhawk to trigger ?

Many thanks in advance,

Paul
