"Been doing this years, have loads of them lying around and they weren't cheap!"
"I Have the same issue. Worked fine on APM. Works fine USB to USB. As soon as I connect pixhawk to xbee, very dodgy.
The odd hearbeat comes through but that's it.
Scoped the pins coming out of pixhawk, can see the hearbeat, looks ok. Scoping…"

"IMO no, the reynolds numbers are too low"
"Wow, that is awesome. I need to get back into the fun hobby side rather than the academic work side ;-)"
"Hi Christian,
Very interesting idea, I think it probably hasn't been done much because of the limited payload. However, if rather than 2x 4Ah batteries linked in parallel to double your endurance you linked them through a LTC4416 in parallel you…"

"James, the Aeropaks are impressive by Horizon (Arcola have close links). Slowly approaching something sensible for our hobby in terms of power density. Although there arent many applications for us where long endurance and low power is desired."
"Thanks for your comments gents.
Rambo, that looks very interesting congrats. I am actually using the LTC4416, unfortunately the 4370 is designed for load sharing equality which my system isn't. The fuel cell is not electrically similar to a LiPo…"

"Awesome project, very similar to my doctorate I am currently writing up. More details below:

"oh, that one is spec'd for 1.8kW ish (i.e. designed for a max of a 4 cell with a 100A ESC). It is very scalable however, just add more MOSFETs to handle larger loads.."
"Thanks gents. If you're interested what it looks like here is a photo of the working prototype. It is the same size as the raspberry pi and stacked on top of it. Original concept was to fly it with a fuel cell inside a Skywalker X8...may still…"
For those following my work, thank you and sorry for the long wait for an update! I am currently writing up my doctorate so as you can imagine I have been a social hermit recently!Nevertheless, I have now had a journal paper published which may be…
"Lol don't give him ideas about HAARP, oh God!
He said that he had issues flying at 1km without shielding, added the shields and flew fine. I am somewhat assuming here that the shielding was the only varying factor between flights. If that is the…"

"50%! Wow, this is significant if true. Keep us informed of the results."
"In which case congratulations on increasing your range.
I think you should have asked your original question a bit differently, however, as shielding APM wont really achieve any of what you are talking about.
Power lines and the mobius are…"

"It is irrelevant to the original question.
So is what you are trying to do is shield APM from incoming noise, or protect everything else from the noise APM generates?
I wouldn't worry too much about noise in the wires, that is why we use filters…"
