Charles Blouin commented on Charles Blouin's blog post 10 km high flight with a 1kg quadcopter!
"Thrust is proportional to air density. Air density is exponentially lower with altitude. This means that the propellers will spin faster at higher altitude. Consequently, the limit is probably how fast your propellers can spin. You need to find a…"

"Ok, this totally looks like product placement now, but I swear it was not planned. I was just contacted by Anik, one of the person working on the quadcopter in the video. He used the RCbenchmark Series 1580 (of which I am the designer) for the…"

John Arne Birkeland commented on Charles Blouin's blog post Pacific Drone Challenge
"My first thought was to build a blimp, giving you 'unlimited' flight time to solar charge batteries etc. My second was that Japan to USA is the same direction as Jet streams flow if I am not mistaken."

Pacific Drone Challenge

Posted on January 16, 2018 at 2:29pm 10 Comments

The Pacific Drone Challenge, inspired by the Xprize, has the goal of pushing the boundaries of what is possible with civilian drones. You have to do it for your name in the history books as there is no financial prize. Could…

Thrust Stand for Large Motors

Posted on October 26, 2017 at 11:00am 1 Comment

My colleague and I received a lot of help from the DIYDrones community two years ago when we launched the Series 1580 with our company RCbenchmark. We had just finished our masters in robotics. After a lot of work, we are now releasing the Series 1780, a dyno to test motors and propellers producing up to 25 kgf of thrust.

Although this…

Almost a year ago, I posted here about how VR technology could help control and perform research on UAVs in an indoor environment and at a more affordable cost. Currently, the most advanced indoor UAV research lab in the …
