Marc MERLIN commented on Chris Anderson's blog post New 3DR autopilot: Pixhawk Mini
"Another random question: on pixhawk, if I want to pass receiver RSSI (taranis X8R), I get the RSSI out, put an RC filter, and plug that into the sbus port of the pixhawk and configure 
RSSI_PIN: 103
Pixhawk mini does not have that port. Can I use th…"

"Thanks, 30A indeed sounds like the most I'd feel comfortable putting through that power module.
As far as how much my motor will use, no worries, I know exactly how much it will be drawing before I take off (through bench testing and a 100A in line…"

"Wait, I don't need to pass 10 through the little power connector going to the pixhawk's power module plug. 
I just need to pass 50-60amps (unlikely that I'd peak at 80, but if so it'd be a very short peak) from the XT60 in to the XT60 out (which I n…"

"Thanks Chris, but that was not my question :)
I need the amps rating, both for the current sensor and if the printed circuit board has a lower rating due to the lack of size on the copper traces from power in to power out, I'd need the lower one of…"

"Can the power module really do 90A?
The documentation sometimes says it's 10S capable, and I've read elsewhere it's 6S. I only need 4S but I'm not sure if I can trust the amp rating. The current sensor shunt says 0M50 on it, and I'd love confirmatio…"

"Oh boy, I can't believe I managed to miss that somehow. I sure do need sleep...
Sorry about this Chris, thanks for your answer and patience.
Given that the pixhawk 2.1 + I/O board is way too big for many of my planes, I'll make sure to give the pixh…"

Marc MERLIN commented on Chris Anderson's blog post New 3DR autopilot: Pixhawk Mini
"Thanks Chris. I did read the 3dr page, it was just hard to tell how it was different from the pixfalcon since it compares against the pixhawk.
Does the board power itself from the servo rail as backup, or is that missing like the pixfalcon?
First, I…"

Marc MERLIN commented on Chris Anderson's blog post New 3DR autopilot: Pixhawk Mini
"And before someone tells me about pixhawk 2.1, it's useless to me until it has a very small carrier board. Right now, it's huge (bigger than pixhawk actually with carrier board and then big cube on top)
Until it comes into something that barely bigg…"

Marc MERLIN commented on Chris Anderson's blog post New 3DR autopilot: Pixhawk Mini
"Sorry if I should have found the answer (I didn't). How is this different from the pixfalcon I already have? It looks exactly the same except for pixfalcon scratched out and pixhawk mini written in its place...
Things I didn't like with the pixfalco…"

"minimosd-extras development is dead. Have a look at night_ghost minimOSD, which is where all the new stuff (and the cleaned up code) happens."

Marc MERLIN commented on vova reznik's blog post Getting to 100km, with a big help from GEB 8043125.
"Thanks Tommy. So I'm confused: if used properly these batteries are great, but yet no one is selling them anymore.
Why were they pulled from the market? We shoudln't have to make our own lipos :)"

"So whatever happened to those batteries, are there replacements that one can buy?
Why were they killed?"

"Dear Robert Pigeon, of course there had to be one of you, there usually is on every such thread. I could spend a long time explaining to you why I (the builder) spent months testing the equipment, safeties, and adding redundancies, why a foam plane…"

Marc MERLIN posted a blog post
A lot of work went into building this plane, adding redundancies and safeties, as well as fitting 3 cameras, and the result was well worth it. Big thanks to the ardupilot team, nightghost for his OSD firmware, and all the other folks who wrote some…
