Hi all,I'm looking for some interesting questions to solve as part of my research for school. As operators/builders/enthusiasts of UAVs, particularly multirotors, what questions do you have? Here's a partial list that I've collected so far that I'm…
Here's a video from one of our recent tests of our GTQ-Cormorant: a submarine and quadrotor hybrid.https://www.youtube.com/watch?v=U7vl7uqwN4IWe use an air pump/solenoid system to move air between the clear, water-tight pressure hull and an…
"Why do I keep promoting it? That's an easy one to answer:
1) so people use it and give me feedback and I can improve the math where it is needed
2) to provide more tools for us to use to help our community design vehicles and defend the parts…"
"According to the spec, looks like the Attopilot sensor will easily handle what you are going to be drawing. T-motor has some specs and at 100% throttle you're going to draw around 100 A for 4 rotors. "

"Yeah, if you look at it on a per-inch basis, pitch change adds much more drag than diameter change.
Changing diameter makes sense if you're after endurance. If it's windy though, you want more pitch to be able to handle the wind."
"You can use this calculator to mess around with some of the parameters. It takes into account altitude/density/temperature and you can check the effect on flight times/range/etc of changing prop pitch and a bunch of other…"
