Valentine Heart with dedication has been crafted on the sky using autonomous UAV.

Well beyond visual range, below frost point, in dense fog. Somehow it worked, over wast swamps near Wrocław, Poland (pronounciation: WrocLove).

The webpage looks like a quick mash-up but it's there. 4x3km, at 300m AGL.

A movie will come a few days later.…

Watch closely at 1:30 and 2:56 even the wolves in popular media have moving object removal and triangulation capabilities.

Hi,

I was able to obtain certain number of XBEE PRO modules at 50mW with wire antenna, no chance to get them with SMA antenna. However I would like to solder a specific connector. Unfortunately, the PCB layout is different:

Type A is for SMA, uFL and WIRE     

Type B is for Small PCB patch antenna,…

The question is, what is that little bulb in the middle?

Hi all,

many of us are using EagleTree data recorder. Sometimes I have several logs that I need to merge between the autopilots and EagleTree. The manual states that you can contact them about file format and they will respond. Unfortunately this is not the case. Therefore maybe somebody has a clue about what the file…

...will tak place 22th to 27th May 2012 in Pałac Kultury i Nauki, Warsaw.

The exhibition will be physically located in Museum of Technology  inside this monumental building.

The Museum is recently known for organising countrywide meetings that have spin-off potential and highly technological subject.…

Hi all, I wonder what is the availability on the market of semi-industrial grade RC helicopter bodies.

For example like this one, Aquila UAV from UAVS Poland.

Is it possible to buy something resembling this off the shelf, with holding space for a gimbal cam in the nose?…

2012-04-23 at 19PM GMT+1, FLEXIPILOT (my own closed-source development) with special Terrain Follower firmware, controlling EasyUAV, has made its first long duration loiter at 1.5-3m AGL above sloped terrain. Loiter diameter was around 110m.

10m Flight took place in steady weather, while…

Hi all.

I have made a long run at 'human flight level'.

The machine is basically EasyStar with FLEXIPILOT but the discussion applies to anybody using typical hobby grade ESC. The plane is equipped with RAY 2845 inrunner motor and RAY 25 ESC, same as JETI ECO 25. Runs on Kokam 4Ah SPLB 30C. The plane is…

Hi all,

I am unable to find exact information about servo tolerance.

For example very popular Futaba 3001 tend to have a lot of loose because ot the gear precision, yet when they run all is ok (besides that they are slow).

On the other hand Hitec HS-425 appears to me to have null loose.

Hitec HS-225 have little loose and is very fast servo, but in order to hold its position requires huge power.

Most digital servos tend to be either slow and fast, but have…

Not sure if it was posted before, looks it wasn't. Enjoy.

Hi,

we have performed RC range simulations for 2 systems:

35MHz, 2.5m mean antenna height, 1m receiver height (vertical mast on the UAV)

and

2.4GHz, 2m TX antenna height, 0.5m receiver height (short antennas)

in order to simulate it over a vast terrain we know and use.

The range plot was made from 4km2 elevation model made by Pix4D and Pteryx UAV.

Treat it as a kind of reminder of what happens when landing using FPV.

We…

Vickers Wellington as UAV

Bi-motor airplane serving as test platform for FLEXIPILOT.

Used for testing single-engine failures and tuning.

Elevator, differential ailerons, no rudder.



Endurance 50min with one battery.

Cruise speed 50km/h.

Shown loiters at low altitude since at typical cruise altitude of 200m it…

Fournier RF5 as UAV

A low-wing stall-prone (due to specific airfoil) motoglider, flown without Pitot Tube.

Endurance 30-45min with one 4Ah battery, but it is so efficient it would fly easily for well above 1.5h.

Yet, I don't like the fact you have to throw it overhead so it will stay limited.

Cruise speed 45km/h.

Shown…

A V-tail hotliner integrated with autopilot.

Endurance 30min because of small fuselage capacity,

cruise speed 50km/h. Shown loiters on small altitude since

at typical cruise altitude of 200m it is almost impossible to track a flying object on a clear…

The FOX is really unflyable in RC mode when the motor is below 30% throttle, autopilot handles it much better.

I believe it could be the smallest _classic_ layout winged _outdoor_ UAV in…
