Did you know you could build your own Li-Ion battery pack ?
Li-Ion batteries have the highest energy density per unit of mass available to us.
In comparison with LiPo batteries, you get 30% less weight for the same mAh capacity, which translates into direct endurance or increased flight autonomy.
This is part 2 of building a DIY folding quadcopter. The episode is about designing a detachable camera gimbal (a Z Tiny2, 3-axis) and a landing gear.
Part 1 is here:…Continue
Here is a DIY design & build of a small (300 class, 9" props) compact foldable quadcopter you can take in a backpack, weighing less than a kilogram (including a Drotek RTK GPS, CUAV V3 pro pixhawk autopilot , telemetry radio)
It can fly a good 30 minutes with a 3-axis Gopro type gimbal (subject of part2). The frame is…Continue
A little laugh with a joke starring my chickens, Penny and Pepsi :)
Oh yes, even chickens may benefit from Arduino tech.
Next step : make ardurover find the path to the chickens house, then recognize if eggs are layed and pick up them up Can DEVs take care of that in a next release ? :)
For RC/UAV uses, a balsa core laminated with carbon fiber makes an ultra light construction panel with very high stiffness. While you can buy ready made panels (usually expensive), this video shows how easily you can make it yourself with no special tools.
This video does not pretend to show the best way of doing these panels. It is…
Unboxing / Disassembly / Review of the CUAV V3 autopilot.
We take a look at one of the latest generation autopilot running the Ardupilot software. How is its build quality and functionality ?How does it compare to a Pixhawk autopilot ?

This is a quick and short review, setup and tutorial of the RTK XL GPS from uBlox/Drotek.
Test & Setup is done on Ardupilot + Pixhawk, using mission planner as the ground control station.
Note that this product was not provided for review by Drotek and the review is unbiased.
The RTK XL product can be found…
This is a synthesized basic explanation of how precision GPS methods work:
-Differential GNSS (DGNSS)
-Real Time Kinematics (RTK)
-Satellite Based Augmentation System (SBAS)
-Precision Point Positionning (PPP)
This is the maiden flight of the latest X-UAV model : "Clouds". It is a V-Tail fixed wing platform, similar to their previous model "Talon".
It runs Arduplane 3.7 on a Pixhawk1 (I try to get a Pixhawk2 for months without any success...Frustrating).
I was supposed to have a flight buddy who would throw the plane while I would hold…
X-UAV Clouds build part 3
This is part3 and the final assembly stage of the X-UAV Clouds build
It is equipped with a barebone Pixhawk autopilot (from Jordi Munoz co founder 3DR, Mrobotics.io) running the latest Arduplane code,
and no need to say this is the best of all ! (thx Tridge and Randy and all others I…Continue
XUAV Clouds build part 2 :
Clouds is a twin motor UAV. Total weight with full payload could get as high as 4Kg.
For an easy hand or catapult launch, a 1:1 weight/power ratio would be more than enough.
This means using two motors producing each a maximum thrust in the 1.8-2Kg range.
So what motor, propellers, battery voltage…Continue
"XUAV Clouds" is the latest FPV/Survey platform from XUAV. I suppose XUAV wants to capitalize on the legendary success of their V-tail Talon model and at the same time compete in the twin motor category against the popular "MFD MyTwinDream" fpv plane.
Its wing span is 1880 mm (vs 1700 on the Talon without wing extensions, or 2000mm…Continue
XUAV (HOOAH aviation technology LTD) latest EPO FPV/Survey model is the "Clouds". Here a quick overview and unboxing video, with some comparison with their Talon flagship model.

Here a shared review of a quite cute and tiny FPV quad, the QX90.
It was unfortunately delivered to me with a built in DSM type receiver so I could not use it with my Taranis radio.
I therefore modded the electronics with another tiny board that is incredible : it integrates a F3 flight controller with all bells…Continue
A 190 size FPV racer kit review from the GEP brand (so called ZX5 model). What's different about the previous FPV racers build I did before is a X frame while my former builds were always made with a classical H frame.
X frames have an advantage over H frames in that they are more symetrical (useful in FPV racing) and they twist…Continue
Made a short explanation video about Ardupilot's antenna tracker as many people are asking about what it is and how it works.
Current release 1.0 is still improving (thanks Randy !)
As a follow up of my latest blogs about FPV hardware, here is a build video. The build is made with the following components:
-DALRC XR215 V2 Full Carbon Fiber Quad Frame for FPV Racing FPV Build in OSD BEC BB Ring: http://goo.gl/dcIW2V
-Foxeer XAT600M DC5V-22V 600tvl Sony Super HAD…Continue
This is a hardware review of an interesting product for FPV racers. I do not know for how long it exists but I could not find any other reviews on youtube.
This product consists in an integration of mutliple components you would otherwise need to solder and assemble together with lots of wiring, thus saving weight and making a…Continue
I was going to refresh my old FPV 250 racer built two years ago with an "old" Naze board and an "old" baseflight firmware. Not surprisingly, the whole firmware landscape has changed dramatically and I had to investigate quite a bit to bring me up to date with current states of affairs (lots of new firmware versions, new flight controller…Continue
To suppress vibrations & jello in videos taken by very lighweight camera brushless gimbals is a challenge as none of the classical methods are working well. The more weight, the easier it is to manage vibrations. When you combine extreme lightweight gimbal with a CMOS sensor technology, you'll get very prone to the so called "jello"…Continue
