   <line>HANDLING NOTES</line>
   <line></line>
   <line>Flying a flexwing microlight is done purely based on nose attitude - where the</line>
   <line>nose is relative to the horizon for pitch, and the angle of the center-post to</line>
   <line>the horizon for roll. There are particular nose attitudes for cruise, climb and </line>
	<line>descent. Changing from, say, cruise to climb, involves changing the power </line>
	<line>setting then placing the nose in the correct attitude and bringing the </line>
    <line>bar back to neutral.</line>
   <line></line>
   <line>TAKE OFF : Full power, as aircraft accelerates, slowly move the bar forward. </line>
   <line>Once in the air, bring the bar to neutral and pull in slightly to keep </line>
   <line>airspeed high below 100ft AGL. Above this height push the bar slightly </line>
   <line>forward for a Vx climb.</line>
   <line>CROSS-WIND TAKE OFF : As above, but move the bar firmly forward only </line>
   <line>once flying speed has been reached.</line>
   <line>CLIMB: Apply full power, push bar forward to set attitude, then bring</line>
   <line>it neutral to trim.</line>
   <line>CRUISE: Tune power for level flight (there is no trim), bar neutral.</line>
   <line>DESCENT: Idle power, pull bar in to set attitude, then bring to neutral </line>
   <line>to trim. Warm the engine every 400ft by applying a small burst of power, </line>
   <line>pulling in the bar to avoid the nose climbing, then releasing it slowly </line>
   <line>as speed decays again.</line>
   <line>GLIDE LANDING: From base or final, enter descent. On final, gradually</line>
   <line>pull bar in for a minimum approach speed of 55mph. Round out at 30ft, </line>
   <line>then flare by pushing the bar out.</line>
   <line>POWERED LANDING: From downwind, make a small reduction in power to enter </line>
   <line>a gradual descent. As you descend, bring the bar in or add power to keep </line>
   <line>the aiming point constant. Again, minimum approach speed is 55mph. Round </line>
   <line>out at 20ft, while cutting power. Flare by pushing the bar out.</line>
   <line></line>
   <line>The pro-pedals-usb.xml.flash2a file contains bindings for the CH </line>
   <line>pedals - reverse steering, right foot throttle, left foot brake.</line>
