Hi, Question for you guru's of the r/c world......I just purchased my Alpha trainer and hope to take her out tomorrow. I noticed that when I power up the plane without the transmitter turned on, it makes no buzzing sound at all, however if I turn on the transmitter, I get a slight buzzing sound. (I'm assuming this buzzing is caused by the servos vibrating back and forth) Please let me know if this is a problem, or is just a minor glitch. The servos all seem to have no binding or rubbing, and seem to turn perfectly. By the way, The plane is equipped with JR 527 servos and a JR Quattro transmitter.....let me know if this is normal or I have a problem....Thanks
