Good to know Gary and thanks. I was going to ask the same question. I just installed mine in my TC3 and it's humming away but I thought it was normal from what you posted on the other thread.
I've always had good success with Hitec servos and I know I'll be satisfied with this servo, it's my first digital servo and so far I'm very pleased
