"Got the same issue trying to download log via mavlink. MP 1.3.30, APM 2.5, firmware 2.x (cannot see exactly thru MP). Have downloaded logs week before with absolutely the same setup - successfully."

Sayan Andriyanov replied to Sayan Andriyanov's discussion Cannot arm Arducopter 3 on APM2.52. V2.8 hadn't that problem. Pre-arm check disabled.
"MP cannot load previous firmware list. I don't know if this happen because firmware generator site is not working, or there's a MP bug. So one can go directly to http://firmware.diydrones.com/Copter/ , download appropriate .hex and open it in…"

"Now arming ok on 3.1.2 too, after reflashing back again. Still don't know what has this been. Maybe the wrong flight mode? I believe I checked it at the first time..."

Hello there)I've recently changed firmware v2.8 to 3.1.2, calibrated radio and accelerometer, and APM is not arming anymore. I also change ESC's to HK's Simonk, but everything else, including radio and its settings stay same. Red flashes withsingle…

Sayan Andriyanov commented on Bob Doiron's blog post PVC V-Tail Photos for DocWelch
"Due to COG shifted forward, rear engine might be facilitated: lesser motors and props. What do you think people: will that work?"

Sayan Andriyanov commented on lot's blog post Quad copter flying for 4-8 hours
"I think it's possible. Just compare your flight 2500 mAh battery and AA rechargeables with the same capacity. About 10 times smaller and lighter, yes?
So, we just need more discharge rate from these AA's - to put them in parallel. As much as…"

"I'd have 2 battery inputs in parallel. Batteries are likely to die whenever they want, and it's a sorry to kill such a rich board in that battery-dependent accident. Another battery in parallel mode will give you enough insurance."
