Quadrotor Flight Controller class at the HiTech STEM Lab at the East Columbia Branch of the HCLS. The purpose of the class is to introduce students to quadcopters through hand-on learning. The studets investigated the physics behind multirotor liftoff, stabilization, direction of flight, and landing the aircraft. Students worked in teams to assemble the
propulsion system and wire the flight controller and power system. Students honed their flight skills through a flight simulator before flight testing their builds in the final class.
Efficiency of powertrain is everything in multirotor building along with weight. Single propel thrust data is available everywhere. But I didn't find anywhere fact how two propels behaves on same axis (co-axial setup). Another propel is then in the first propel airflow. Two propels side by side could be calculated approximately as 1+1. Internet discussions says often that two propels on same axis is calculated as 1+(1*0.7). This test bench I used for testing that myth. My test results didn't fully support the myth. My results shows more like 1+(1*0.78 or 0.85). If lower prop runs faster then efficiency is better. Higher pitch (chinese wooden 1480) as lower prop made efficiency even lower if rotational speed was same on both props. Propels I used were APC 1455 MR and APC 1455 MRP.

South Haven Lighthouse on Lake Michigan during a winter snow storm on January 6th. Ellen measured the conditions with a Kestrel as Temp 18F, Feels like -1F, Wind speed 15mph, Gusts of over 25mph. Waves 8ft and building to 14ft. We were out around sunset between 5 and 5:30pm. Watch the video at: youtu.be/ECHaHaZpMjQ

A three-hour blackout in West Hollywood, Calif. on Monday was reportedly the final result of a drone crash. The BBC experiences that a drone was flown into powerlines, knocking a person of them down to the ground and leaving about 650 people with no ...

Lors de mes crapahutages à pied dans la campagne, j'en avais marre de devoir me trimbaler un trépied photo complet et tout un stock de câbles pour la station de réception FPV. L'année dernière, je l'avais déjà remplacé par un manche à balai télescopique en alu, que je plantais dans la sol et maintenu par des haubans. C'était déjà mieux question poids mais encore trop encombrant. En plus, ça prenait pas mal de temps à tout installer, brancher tous les câbles pour pouvoir enfin voler. Cette année, je suis allé un cran plus loin en supprimant complètement de mat.
Dorénavant, c'est "moi " qui serait l'antenne...
