Displacement during snap rolls

[Don Ramsey]

Here's a judging technique that helps to actually see the snap better.  The initial break is easier to see by viewing the tail, longer moment, more break visible.  To help visualize the cone of a snap (and the entry break), it is easier for me to focus on the model just behind the wing.  Your peripheral vision can now pick up the cone more easily.  Seem to work for me.

  Hi Karl,
  You already know the answer to that! Rapid application of many "G"s causing the stall speed to rise.
  Of course, first you have to make lift to stall, which meand that you are starting to leave that perfect vertical line.

  Happy New Year

    All,


    I have a question on the aircraft to be in a "stalled condition during a snap roll":
    How do you get the airplane into a stalled condition on a vertical downline snap?
