High-altitude multirotor drones?

Avoiding mag compass interference from motor current

I'm building a fixed wing UAV with a 2.6 m wingspan and a fairly large fuselage bay.  The electric motor is in the back (pusher style), and it's driven by a 6s 10000mAh LiPo battery and a 60A ESC. …Continue

High-altitude multirotor drones?

I'm  a fixed-wing guy (so far), but I have a  possibly naive question about the maximum altitude that off-the-shelf multirotor (quad or hex?) drone can reliably reach if your objective is to quickly loft a modest (say, <200 gram) payload exactly vertically to some specified altitude above the starting point and then rapidly descend back to that starting point and land again before the battery is exhausted.I think I've seen online that some homebuilt copters have set altitude records well in…See More

"For the Pixhawk2.1 (by HEX) (by ProfiCNC) the sensor connectors are JST-GH here is a link to a Digikey search that has all the housings: https://www.digikey.ca/products/en?FV=ffec095b,ffe0013fThe power plugs use a different connector"

I'm building a fixed wing UAV with a 2.6 m wingspan and a fairly large fuselage bay.  The electric motor is in the back (pusher style), and it's driven by a 6s 10000mAh LiPo battery and a 60A ESC.  I'd like to be able to put the battery in an adjustable position forward of the wing to aid with the CG, but I worry about the 30 or so centimeter distance between the battery and the motor, as the current flowing through the power wires could potentially interfere with the mag compass if it's…See More

"The Hugin quality is decent. Minus build plans and some shipping damage, I would purchase another one, but find a direct seller for a cheaper price. Mine is almost complete, working on the tail section and booms now. Whats the process and…"

"Any suggestions on one- or two-stop shopping for miscellaneous electrical components like buttons, switches, LEDs, connectors, power cables, etc.?  I can track down any of these parts individually, but it would be nice to get most of them from…"

"How is the build quality of the Hugin? I was looking at another product from FPV Model - the MUGIN - but was not able to find much information from others that have actually built one.   If you need help building your plane, let me know.…"

"I'm getting close. This was my first build beyond a simple foamy, so kind of ambitious, but I think I'm past the trouble spots. It took me some time to puzzle through some things, and I ended up redrilling the aluminum pieces for the main…"

Has anyone assembled this fixed-wing UAV airframe (Hugin 2.6m)?

I recently bought the "ARF combo" version of one of these:  https://www.fpvmodel.com/hugin-ii-electric-powered-uav-2-6m-platform_g46.htmlSo I got two large boxes a couple days ago with airframe components, motor, ESC, servos, and about 15 different flavors of screws, nuts, etc.  – and NO diagram or assembly instructions! Some I can figure out, but a lot I can't. And I'm not even sure everything I need is…See More

"Very useful page.  However, there is only one reference to Pixhawk2 (under Molex CLICK-Mate) and that's to the "3DR version".  I got my Pixhawk2 from the source (Australia, if not mistaken), and I didn't think it was…"

"The switch is really not that difficult. I switch connectors all the time and am constantly making my own cables because I do not like 4 feet of extra wire for something that only needs 3 inches. That being said I do understand what you are saying.…"

"Molex clickmate on power connector, JST-GH on others. jDrones have all those cables ready made. They also carry DF13 - GH adapter cables from 2 pins to 8 pins. Various lengths. "

"Thanks for the leads.  Could someone say what the precise connector types are on the Pixhawk2 so as to make it easier to search from them on various vendor sites?"

"Good to know. Does anyone know where to find pixfalcon connectors? I know DigiKey carries at least some of it, but t's not crimped, mght not have the same pitch, etc. Is there anywhere I can buy pixfalcon plugs off the shelf?"
