I've got this bugger of a problem with my aileron servos. The plane is a p-51 mustang arf with the jr 600 receiver and the jr sx6000 transmitter. While doing a pre-startup this morn. the servo started buzzing. I swapped the leads around and it still buzzes. If I turn the tansmitter off, it quits.(radio still on). I double-checked the receiver leads and all looks good. I'm going to check the mounts tonite but is there anything else I should be looking for. I'm hoping to put in my first flight (With an instructor) on Monday Thanks [8D]
