"@Bart Theys, this brings me to another point: my aerodynamic knowledge might prove me wrong, but I'd think that the static thrust is different from what you'll get in flight. As such, one might consider measurements in a wind tunnel rather…"

"@Maxence, some years ago I did a limited set of tests to measure the influence of configuration, arm shape, push-pull and documented it in this paper. There will always be a difference between the measured values on a bench with what we get…"

"Hi Maxence, For 1 and 3 - We have done tests to evaluate the effect of the arm on the test results. There is no simple answer to the variability, unfortunately. Our protocol requires recording the test environment. I made a post about this…"

"Hi Charles,  I really appreciate your job. I own a series of racerstar motors and I am glad that you began to test it.  Do you have a list of assumptions that you make before testing the power train? I have some questions about your work…"

"@Wojciech Batog I understand your concern, and this is why we made the Series 1520: we started the company with hobbyists in minds. This is also partly why we made the database openly available: everyone can use it. The R&D costs for…"

"This is a very good initiative. It is now very hard to find reliable thrust data for electric motors especially the larger ones.It would be great if you could get some (preferably all) manufacturers to submit their data.Unfortunately, I feel that…"

Challenges in Designing a User-Contributed Motor and Propeller Database

I will discuss the challenges of designing this database. Searching for the right propulsion components for a UAV is tough. There is not much data available, and what is available from suppliers is not standardized or reliable. Even with the right tools, you still have to buy and test many components before finding the right motor and propeller. My team and…See More

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…

The Otus Tracker by RCbenchmark: a more affordable motion-capture system for drone development.

Posted on September 10, 2017 at 1:45pm 3 Comments

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 …
