"One thing about 18650 cells is they have a way bigger magnetic field than lipos. I think it is particularly bad when cells are oriented vertically. You need to keep it well away from your magnetometer. Something to keep in mind."
"While the test might show a phantom the rules aren't phantom specific. They apply to any UAV including heavy walled carbon fiber / aluminum lawnmowers. The concern is mostly within control areas when commercial aircraft are…"
"Kind of a crazy debate. Even if 10 phantoms went through a jet engine without a catastrophic failure nobody here wants to be flying in the 11th. Beyond that there is a huge variety of construction materials and geometries in drones so…"
" I worked at a company that used a cheap ground proximity sensor (sonar). It was the cause of a large percentage of the crashes we had. I would guess 50%. I think linking the logic to the altimeter to reduce the chance of…"
Hi I'm trying to reproduce an intermittent flyaway bug and I found some behavior that surprised me. We have a quad that we wanted to control strictly through mavproxy (sometimes no rc receiver plugged in). When we unplugged the RC we found that some channels could have noise induced values and could cause random yawing or leaning one way or another. If we used the self.module('rc').cmd_rc([3, 1050]) - Throttle in this case we could keep the channel voltage from free wheeling. If you do…See More
" What a great thread. The "higher end" drone companies are in a tough spot actually. They have to jump through all the regulatory hoops (battery certifications are particularly nasty) and any changes they make require…"
"earthpatrol: What a fantastically insightful post. In this industry there is a great deal of throwing a lot of crap at the wall and watching where it sticks. When it sticks somehow that is proof that it is good enough. Even…"
"It would be great if you could test the WN822 to see if it supports monitor mode for the rest of us. It would be great to have a dual antenna output on the vehicle end since there is almost always a blind side with a single antenna."
"Pixhawk replacement. I would prefer an offboard barometer/mag- allows for better weather sealing and mag isolation. Redundancy on the pixhawk seems lame considering how reliable processors are compared with the rest of the vehicle.…"
" Thanks for letting everybody learn from this event. It is almost destiny for flying machines to crash given the chance. I find a lot of RC flying is minimizing risk and managing trust. Batteries seem to be the most fickle…"
"Might be worth disabling the RTL gain in altitude if the vehicle is closer than 30 feet (even better if it is a user selectable distance) from its return location. Having it climb is a very useful feature but it can cause problems in some…"
