RE: WHY COMPROMISE!!!
there are good and bad products from china. where do you think hitec and other name brand servos are made? thats right, china! lol
if your pack is only 7.2v hitec makes a receiver eliminator harness thats like a buck. just a y harness that sources power right from the battery to your servo and it y's off to still get signal from the receiver. worked really well on my RC powerwheels project using the 805bb servo. but then again my powerwheels was 6 volts, 7.2 to a servo should be fine. but if you run a 3s lipo or big nimh pack you will need a bec to prolong servo life.
