I have returned to the hobby after many years of absence and I now have a 4 star 60 which utilizes a Y harness for dual servos for the ailerons. I have seen a plane at our flying field which utilizes 4 servos on a Y harness for ailerons. I am not aware that when you buy a servo or receiver that manufacturers specify the limits on the current pulled per channel on a receiver or the current requirements of a particular servo. I have asked this questionat my club and the answer that I got was that the current requirements are so small that it does not matter but this does not satisfy my curiosity. Can someone give me a more definitive answer?Thanks</p>
