  1. Well that is totaled. Poor little Cessna!

    1. Nah, that plane will be flying again quickly. 180's are worth too much and that just looks like a wing and HS and inspection of the center section (without seeing it all).

    2. I don't think it's totaled.
      Should buff out.:)

    "Takeoff: The next difference you will notice comes during takeoff. With a tricycle gear airplane, you accelerate down the runway, the airplane pretty much rolling straight on its own, until you reach a desired speed, at which time you simply pull back on the wheel and lift off. Takeoffs in a taildragger require a lot more work. Predominantly, right rudder will be required to keep the airplane rolling straight down the runway, but constant rudder corrections are necessary to keep it rolling absolutely straight. With the tailwheel on the ground, most taildraggers are rolling down the runway right at the stall angle of attack. This is by design for landing purposes.

    The normal takeoff procedure is to raise the tail just a little to the proper angle of attack for the airplane to fly itself off the ground. When the tail comes up, you lose the traction of the tailwheel, so a little more right rudder is required to keep it going straight. Also, there is a law of physics that says when the plane of a gyro is tilted, it reacts with an opposite force 90 degrees in the direction of rotation. Well, it turns out that the propeller is a pretty good gyro. When the tail comes up, you are tilting the plane of the propeller. The force you are applying is the equivalent of pushing at the top of the propeller arc from behind. Since the propeller is rotating clockwise when viewed from behind, the gyroscopic reaction comes as if it were pushing on the airplane's right side of the propeller arc. This tends to turn the airplane to its left while the tail is actually moving up. So, while the tail is moving up, an extra dose of right rudder is required. A good taildragger pilot leads with a little extra right rudder an instant before the tail starts up to keep the nose aligned perfectly straight, rather than waiting for it to start left and then apply the correction. Also know that the more horsepower the engine has, the stronger this gyroscopic reaction is, as well as torque, so more right rudder will be required. In some really powerful airplanes, you would not have enough rudder to counteract these forces, so power is carefully applied and increased thought the takeoff roll so you don't run out of rudder.

    Once you get the tail up and stopped at the desired pitch attitude, you're in pretty good shape. The airplane is picking up significant speed now, so the rudder is becoming very effective. The P-factor is also reduced with your now lower angle of attack. You still have to pay full attention straight ahead and use the rudders to keep the airplane going straight, especially in a crosswind. Soon, the airplane lifts itself gracefully off the ground. Many people get the tail too high on the takeoff roll and then pull back on the yoke to lift off. It's better to learn the right attitude for your airplane so it flies itself off under normal conditions. This allows you to look straight down the runway and ignore the airspeed indicator so you can keep the airplane straight."
