Help with voltage regulator selection

For whatever its worth Dimension Engineering makes a very nice 5v/6v selectable BEC that will provide 3.5A continuous from up to 24v with no additional heatsinking or airflow (its switchmode.) which would work nicely in this application and be far more efficient.

I don’t know why Jim hasn’t chosen to carry them yet. ahem

=D

Um… I plead insanity! :open_mouth:
placing order… lol

Hehe I needed to order the 2 x 25’s in anyway. :wink:

Why not use the easiest and most obvious solution? Add a 6V NiMH pack to power the board. Sorry if I missed the reason this solution was discarded.
