Recently bought the J41 and to me it's a pretty challenging little plane that keeps me off the street and out of bed, but I think I am making (a little) progress.
When I am powering up the plane (strictly according to the book) and bringng the avionics on line I am experiencing a high pitched noise the instant the avionics are activated. I was wondering if this is normal. Anyway I haven't been able to get rid of it; the mute button only works for the dings and dongs during the power up but not for this sound.
I have searched the forum for this and related topics but couldn't find any. Hope anyone can help me out.
Thanks
