"I tried this, but my APM1 wouldn't work.  Turns out it wasn't getting enough current - the onboard regulator is wimpy or bad.  I added an external 7805 on the avionics battery pack and it works just fine. Beware using USB,…"

"They're cut from the same carbon-structural foam-carbon layup as the frame, with some aluminum brackets epoxied onto the end to give me something to thread screws into. -j "

"It's 12lb without payload (as seen in the first video).  Battery mass is non-trivial - not quite 5lb. I figured putting the batteries out on the arms was probably suboptimal, but we eventually want a heavy payload underneath (simulated…"

"hey all, I've got a large hex that I'm having trouble tuning.  I've got rate_P at 0.04 and tried stabilize_P at 3.0 and 3.5 (couldn't tell a difference).  I can't fly as much as I like, so my testing opportunities…"

"That's the list I was using to locate some replacements for the Scorpion (and where I found out the Scorpion is not recommended). Finding half a dozen large ESCs was problematic, and I have a short time frame to get this thing in the air, so…"

"The Scorpion Commander definitely doesn't like 490Hz - I have it at 50Hz.  I can adjust that one back up, but I'm pretty sure it didn't like 100Hz so I dropped it to 50. There's a manual?  Where? The only…"

"OK, dumb question: which mode is a basic "fly with the stick like a Gaui" mode?  My interpretation of the documentation is that I should be in stable mode.  Is that correct?  Should I be in acro or some other mode? Stable…"

"I've lost count of how many times I've checked the motor rotation, prop direction, and calibrated the ESCs.  I finally did the reversing in the transmitter so I didn't have to remember which ones to reverse during the radio…"

"did that, several times.  I'm just not seeing anything useful.  Spending hours wading through forum posts, ditto. Varying rate_P from .09 to .145 and varying sabilize_P from 3 to 5  shows no appreciable difference, but then…"
