The hammerhead is a fairly basic
maneuver that is easy to accomplish and master. To do a hammerhead, fly up-wind with your wings perfectly level. Now increase
throttle to full and pull perfectly vertical. As it goes up about 20ft chop the throttle to about a 1/4 and let the plane
slow. As it approaches a stall, apply full rudder in either direction. It sometimes helps to apply a little
throttle to get air flowing over the rudder. As the plane rotates, slowly release the rudder and let the plane go down line.
Pull out and return to level flight at approximately the same spot where you entered and pulled up. Try not to "dump" the rudder off as the plane rotates because
this will cause the plane to 'wag' it's tail on the downline. Let off of the rudder gently for a smooth and very dramatic maneuver!
