Get self centering piece for the futaba, if you are going to use a quad u will want the centering stick. With the throttle curve u will find it hard to find a perfect hover which basically defeats the purpose of a quads ability to hover and not descend or assend a bit. It's free from futaba or like 20 bucks from a dealer. Takes 5 min to infallible. Without u will never sit in one place and hover perfectly. Also no need to remove stock receiver it actuall gets same distance as the futaba receiver. And is lighter so u don't add weight. Don't take out stock antennas either very unneeded.
