welcome to flybarless gair  heres a tip 1 the servos wont recenter like normal servos on this bird  tip 2  spool it up slowly and slowly counteract the way it wants to tip etcetc   as far as the first post these are settings on the users preferance ! its a good starter point but you may not like it  if your first time user then u wont see any differance in this the point im trying to get by is wether your a "pro" or "beginner" the settings provided by eflight work fine ! take for instance the expo settings in the eflight suggested i DONT like the way the bird flies with the settings so i turned it back to 0 and fly without it sooooo i guess its all the way you feel comfortable with the bird and how it react and handles ! i have read all over about the bullet blades and non bulletts  i prefer the non bullets  bottom line ITS ALL ABOUT WHAT WORKS FOR YOY AND HOW COMFORTABLE U FEEL WHEN FLYING !
