How to make a carbon fiber core balsa panel - tutorial - DIY

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…

Drone Pilots Are Buying Russian Software to Hack Their Way Past DJI's No Fly Zones

Should drone owners be able to fly their drones wherever and however they want to? This is the question increasingly asked by the consumer drone community as drone giant DJI tightens flying restrictions on its customers.

This was the…

Getting down to target weight has been challenging.

This version is lighter, stronger, and stiffer than its predecessors. Only airtime and hard landings will show if its good enough.

I'm printing in PLA with 60% infill, 0.2mm layers and slow print speeds which seems to give the strongest parts.

I'll post photos when its…

Aeromapper Talon demonstrates BVLOS capabilities by flying 30Km away from operators

This time an Aeromapper Talon flew a mission autonomously to a target located 30km away from the operators, while maintaining at all times a strong communications and control link. This demonstrates the great potential for Beyond Visual Line of Sight operations for applications such as power line…

Phantom 4 vs dji Spark

Just a comparison video for the benefit of anyone curious.

on a side note, it is strange that DJI has decided to make you connect to the controller via wifi (and has decided to use a stunted mavic controller), i found that you could connect via cable to the dji application via USB because my wifi…

Intel cancels Edison, Joule boards

It was well known that Edison was going to be discontinued this year, but Joule, which was just released, is a surprise. This is bad news for any autopilot board that uses Edison, such as Pixhawk 2.1, which will now have to move to another companion computer. (I'd suggest Raspberry Pi). From …

The main parameters for choosing best drone battery

basic parameters of drone battery

Here are some tips to help you consider the main parameters for choosing a lipo battery for your drone. 

Main parameters


Normally, more capacity is mean more power and more energy. In fact As the battery gets larger, the increase in flight time becomes ineffective, because of the weight of battery. You should have to think about the weight when consider the capcity, Should not be absorbed in choosing bigger capacity battery…
