RE: lipos for rx power
for some reason people just dont like to give direct answers,,,,the answer is YES ,,,,now hat you dont want to do is ,,use the directly without a regulator as stated and you dont want to drain them below their minimum voltage,,or they are trash,,,so you must weigh the differences,,,use a nicad or nimh and no reg or extra points of failure,,and cheaper to run with no balancing or special care,,,or go the lipo route,,,its up to you...
