DIY LiDAR scanner using the LW20 and a digital servo

Making a small, low cost laser scanner for sense-and-avoid applications has been a objective of mine for several years. What makes this project challenging is the cost and complexity associated with motors and their drivers to provide the motion, position encoders to provide accurate aiming…

Circle formations of fixed-wings in Paparazzi

We have recently developed and tested a formation control algorithm for fixed-wings in Paparazzi. The position of an arbitrary number of vehicles can be controlled in a circular path. In fact, we are not restricting ourselves to circles but to any closed orbit, such as ellipses, thanks to the …

Land-o-Lakes ag drone challenge with $150,000 prize

This seems very doable -- indeed, I think an off-the-shelf product from PrecisionHawk or Agribotix can already do all of this. Am I missing something?

Challenge Overview

Montana joins states with drone hysteria by promoting bad drone law

The Montana Senate Judiciary Committee took testimony on a bill that would apply a civil fine against anyone flying a drone less than 500 ft over private property.
It's a dangerous step towards outlawing drones altogether, and could hobble our growing UAS industry in Montana.
Here's the text of the bill…

Full PX4 Support for E-flite Convergence

After our Christmas experiment of getting the E-flite Convergence flying autonomous missions with PX4 we’ve now gone one step further and implemented a rate controlled acrobatics mode in fixed-wing. This allows you to fly the Convergence in the same 2 modes which the original flight controller…

Videos: Cargo Drones Deliver in the Amazon Rainforest

The Amazon is home to thousands of local indigenous communities spread across very remote areas. As a result, these sparsely populated communities rarely have reliable access to essential medicines and public health services. Local doctors in the region of…

XUAV Clouds Build - Part2: Motor-prop-battery combo thrust test

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…

Maiden Flight of Ranger EX 757-3

I completed the maiden flight of my Ranger EX 757-3 today, with mixed results.  The flying weight today was 6lbs, using a standard rule of thumb, the power requirements would be 450 - 600W.  The supplied 3715/1000KV outrunner brushless motor only provides 300W.


  • Initial parameter selection flew the aircraft safely and successfully in Manual and FBWA! 
  • The build was good (no bits flew off)!
  • All the systems checked…
