I posted a blog on a Ball turret Gimbal design and build It appeared in DIYDrones with only 2 of the nine photos, and the text all garbled in between!! The preview before posting it was fine .Was…Continue
Good Day all,I have been spending a lot of time analyzing many different aerofoil profiles to optimize said profiles for a very specific flight regime. If there are any experts with good knowledge on…Continue
Hi Chris, maybe Bill (P) and other sensor boffins..Is there any temperature compensation and sensor orthogonality offset ( measured on a rate table maybe) done on the APM series autopilots? Has any…Continue
This Autopilot system is the system fitted to the various UAV's designed and flown in Namibia for nature conservation and to support the anti-poaching programs there.Have a look at the postings under…Continue

Here are some photos and a short video of a 80mm diameter fully articulated turret Ball, currently fitted with the FLIR TAU-2 IR video camera.
Camera and lens is approx 100grams. Complete assembly is 220grams. Camera line of sight view is from 15deg below horizontal, full 360deg coverage. The Ball…Continue
Around 10 days ago I started a debate on wing Aerofoil choices to improve flight range rather than endurance. A number of folk joined in with ideas and suggestions, and the choice was eventually made - The Selig S7075 at 9% thickness.
Many Aerofoils were simulated and the S7075 choice seemed a good one, so I proceeded to make a prototype set of wings to begin some trials.
The 'original' wing is a Clark Z Aerofoil, 316mm Chord and 1.8meter span. Fitted to our…Continue
You may remember our previous posts of Guppy, Hornbill and Kiwit. Well, we now have a fully composite UAV, called SurVoyeur, in production. This aircraft is a sub 4.5kg electric, able to carry up to 600grams payloads for up to 45minutes. It is also a fully autonomous system, with full autolaunch and autoland in harsh terrain. It has been extensively flown here in Namibia, mostly on land surveying missions, photographing up to 150hectare in one flight. We have fitted it…Continue
