Default High Frequency Squeeling... is it normal?
Finally got a chance to give this little dude a flight this past weekend... wow! big difference between the 4#3b and my CX/2 and mCX!!!

There seems to be a very high frequency pitch squealing noise coming from the 4-in-1 unit... is this normal? I played with the EXT adjustment, but didn't do anything. Thoughts?
