There are occasions when you need a reliable 5V supply to power your receiver and servos but only have a 1S battery available. That's where this device comes in very handy.
Whether it's in a very small model or a DLG, where weight is very important, the MPN booster seems to do the trick very nicely.
This unit was purchased from HobbyKing for review purposes but will be going into a composite 1m DLG currently being reviewed.
