MAINPRAGMATIC V tail: A V-tail can be lighter than a conventional tail in some situations and produce less drag, as on the Fouga Magister trainer, Northrop Grumman RQ-4 Global Hawk RPV and X-37 spacecraft. A slight modification to the V-tail can be found on the Waiex and Monnett Moni called a Y-tail. The control surfaces, sometimes called ruddervators, act differentially to provide yaw control (in place of the rudder) and act together to provide pitch control (in place of the elevator). With the Cardinals one out away and the Giants down to their last strike with Joe Panik at the plate, Rosenthal spiked a 3-2 pitch in the dirt that went to the backstop, and pinch-runner Matt Duffy was able to score all the way from second base to tie the game once again. Here, the tail surfaces are set at diagonal angles, with each surface contributing to both pitch and yaw.|Strategy of American Football
