"From the website "The vehicle’s yaw is controlled by adjusting the speeds of the two motors. I.e. speeding up the clockwise motor while slowing down the counter-clockwise"Didn't you guys forget the 2nd motor?"

"Guys, how about NAFEMS compliance? Flow over the standard sphere, flat plate etc.? Or, let me put it other way around - how accurate it is?"

"The device itself must contain aerospace graded IC components inside. The components graded for aerospace are -55C to 125C (with a standard being -40C and military grade being -65C). Price difference is 20-40%.
Another thing is tripple a redundancy…"

"I might sound noobish, but how on earth do you determine N & E error. I mean, how do you know the coordinates of a fixed point(i.e. base-station) you're measuring error against, with such level of accuracy?"

"Martin, is that the same airship from your previous post?
Would be interesting to see how it swims in the air. And because you've stabilized the video, its even more difficult to understand its true orientation.
Was there any wind during the flight?"

"@Jacek, where did you get that "Flex Wire" from? Tried googling on that keyword with no luck."

"I ran a similar test last year. 
Hand-made Inverted-Vee gave me the best performance."

"@Marthin H.,

the problem with blimps is -  they can't be small and efficient, just like quad's can't. 
it seems your L/D ratio is 6:1? That's not a shape which gives you a smallest drag possible. I've done a study and, surprisingly, 3:1 is a way to…"

"I've made it 73km with a simple dipole antenna attached to RF1276 (SX1276), and would have gone more, if I were higher, as I've reached a horizon limit. -148dB RX sensitivity. Not willing to promote anything, but 168dB link margin is quite…"

"I was always wondering why it is recommended to hover at ~50% max. throttle? Also, I was always wondering why people are checking max. thrust for evaluating max. lift capability? Propeller/motor has a max. efficiency at ~20% of its max. thrust. So,…"

"thanks Andrew, now I'm back to my experiments of replacing IP comms with FCOE on RbPi-based video streaming."

"Andrew, can you please confirm this is not a typo error and you were really able to achieve 250 microseconds delay? That's some 700x better than the current setup drones community has been using (RbPi + RbPi camera gives some 170ms)"

"@Martin - here's the URLto schematics and firmware
I must also apologize Simon for hijacking his original thread.
Your problems seems rather obvious - your battery can't handle high currents or has relatively high internal resistance (likely both).…"

"@Simon,
LTC4416/17 Family is an interesting thing indeed. Wonder how did I miss it. I've rejected LTC4370 for the same very reason as you did - it only enables 50/50 load-sharing. Plus, package is to small for diy PCBs.

@Christian,
I've implemented…"
