really unless you scuff the servo cases up before you glue them, with a little persuasion you can get the glue off quite easily, definatly if you want to keep it light itd probably not be best to use and extra tape. but if you were using say a 370 on it youd have no problem you might not even notice it stock with a 300 but if you tried to get it real light every gram counts. and im using a 9x3.8 and ive decided im switching to a 3 cell 340mah lipo run time is expected to be about 7 min
