Hey guys

I am having a problem with my Servos for the Right Middle and Back flaps.... its connnect to the proper channel and it works... seems to not have anything wrong with it.... but when I move the stick back and forith... it moves... little bit forward and when i move the stick back it moves back but probably 6mm in all back and forith... mainly it moves but not properly.. the way it should...

anyone with suggestions please inform me please....

** And as well why is my jet beeping so much?***

Thank You
