Here is a realy light adjustable voltage regulator about half way down the page. I bet this would make a really good reciever power source with a 2 cell lipo.

What do you think?

If you used two of their 150 ma lipo's in series you should get more than 150 ma with the voltage reduction. Maybe at least 150% over - so about 225 ma. total weight under 10 grams. I guess it would be expensive at $38 but it sure would be light!

The nicest part of this converter is that it already works with 1 Lipo cell.

But.......I still hang on to my "old"setup for the following reasons:
1- it is cheaper. Under 5 $ for the 3 electronic parts. (I found out the connectors I used were more expensive)
2- it is also light. 5 grams including wires and connectors. Less than 2 grams without wiring .
3- Buck regulators are very efficient but also switch on a relatively high frequency (this one uses 550kHz). This might cause problems with your RX or servos if not well blocked/ filtered.

If I am going to use one of these I first want to try it on a sloooooow electric powered small and light plane. Safety first!
