Hi all,

Just thought I should raise a bit of awareness into the research being conducted at Loughborugh University here in the UK!

I'm in the early stages of a 4yr project implementing both PEM and SOFC fuel cells into small unmanned, commercial off the shelf, aircraft using ArduPilot Mega 2 (later ARMPilot when it comes out!)

More info is on my DiyDrones profile!

One thing I'm currently seeking advice on is connecting two power supplies to one ESC.  I'd sooner have an ESC with two inputs that is already set up for redundancy and switching between the two power supplies when one runs out (voltage cut-off).  Does anyone know of such a device?

Happy flying this summer!

Simon
