"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,…"
"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…"
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?
"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…"
