I still think for a low power device like the flyduino is a lienar regulator is the way to go.
Switching supplys can be troublesome, can, dont have to.
There are quite a lot powering options, easiest is to take a BEC 5V or the onboard regulator, but a external switching supply should work too.
Fair point Paul
I was struggling to find a reason why there might be an advantage to using an external regulator
The current draw will be so low that very little power will have to be dropped across the regulator = very little heat would be produced ...
