Arbutus commented on Chris Anderson's blog post New 3DR autopilot: Pixhawk Mini
"The FC only uses a few hundred mA.  The question is whether the power module can safely and continuously handle the peak current that the aircraft requires.  

IMHO the Mini 10S power module is good for about 30A or put another way, a 350-450 size…"

Arbutus commented on Chris Anderson's blog post New 3DR autopilot: Pixhawk Mini
"The quoted ratings for most small electronics in this hobby are usually very exaggerated.    The 14awg wire used for the 10S power module is normally considered suitable for up to 10 amps.  The XT60 connector is considered appropriate for up to 60…"

"Has anyone figured out how to connect the RFdesigns 900+ modems to the Mini?   The pinouts appear incompatible."

"Happened to me a few minutes ago, bench testing a U-11 and a 29" three bladed prop ($420 each!)
