"How did you arm the APM before plugging the power in?"

"Sorry for the tardy response, been tied up with other stuff. Yes, I have one left, sitting right here on my desk. I'll PM you :)"

"Checking the battery unloaded isn't going to tell you a whole lot.  The fact that you've got a swollen cell is very, very suspicious.  It's entirely likely that cell's output voltage drops badly when you start pulling some current out of it."

"Yep, that Tx is only $23 (!!!!) and it includes a Rx. They're a good deal for the money.

Keep in mind that depending on your country, it may actually be illegal to fly a RC aircraft without it being under you direct control. Direct control will…"

"The reason for the adapter is that the APM2 has a hole spacing that doesn't match any of the holes already built into the HT-FPV frame, and I didn't want to drill additional holes. You could double-sided tape the APM2 onto the frame, but I also…"

"I get a similar issue.  I definitely have current sensing working in the hardware (the AttoPilot current output pin varies in voltage as the current varies), but my current and load metrics always show as 0 in the Planner.

I'm using 1.1.96 with…"

"Only catch I see there is that as soon as you hover, the wheels will fall off (metaphorically), since your direction of travel will change very rapidly as you balance the hover. Of course, you could rig up the mode to auto-disable when the forward…"

"Wow, things fall off this board fast.  Any way to get more than 10 items on the front page?"

"Hold on a moment.

When you say the ESC produces 6 volts, are you measuring this open with a voltmeter?  The ESC regulation circuit may be a switching type, and you can't rely on the voltage output being sane on them when you're not drawing a load…"

"Pretty much anything acts as an RF shield to some extent, particularly when you're talking higher frequencies.  It shouldn't damp your range too much, but as always, range check it anyway."

"Is the issue here that the _earlier_ boards had an issue and not the later boards, but the code was written with the earlier ones in mind?  IE, newer boards don't actually have something wrong with them?  I'm asking this because my APM2 order is due…"

"My air module is like the picture at the top - purple breakout board, daughterboard is rotated 90 degrees and soldered on using a pin header.

My ground module has a similar orientation to the bottom picture - green breakout board, daughterboard in…"

"Only if their network IDs and other parameters are the same, as per;
