"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…
"It is interesting hearing you guys over the pond talking about the 5mi zone being nonsense and prohibits many RC clubs. My club over here is very close to an international airport (EMA), but we have a written letter of authority to fly at a certain…"
"I dont see how this is any different to launching fireworks or flying a kite at the end of a runway. Why does the "drone" have to be the focus of the story. Surely it should be the turbo mong of a pilot, who should have the balls to come forwards…"
"Try here"
"Im confused, have you done any of the build yet? Is it all still in bits and you want help with how to plug it all in or have you done all that and just want to know how to set up the software?"
