kro.... This a fact... the longer you fly,,the worse your fly'n gets.... I have kept all my flights about 3-4 min...Now,,,,,, you can think I'm full of it or not,,but try this... at 3 min,,,shoot for a landing,,,Bet if you have any time on the sticks..your landing will look great... then fly for 15 min,,,and land again...it won't look to great,,,,now wanna push it?? fly for 25 min,,and then land..I would be willing to bet my whole paycheck for the year,,it will suck... bouncing and or just a good ol fashion hard landing...maybe ripping the gear out....

WHY???

As a profesional shooter and teacher of flight.. your eyes are taking a beating ALL during the flight.. "3D pilots" are really impacted on this,, your eyes focus out- in out- in and so on and so on..the more they do this,,the more energy your body has to produce... One of the hardest things to do to your body is flex the eyes... (lots of energy) thus..making it harder to control the plane at your finest... 3-4 min,,and take a break..your fly'n will love ya for it....
