[NSRCA-discussion] Snaps

[Del K. Rykert]

I will have to disagree with that Matt..  As I can snap my pattern ship either direction as well as upright or inverted. One may present better than the other but it will do a true snap.

  Rc Master, I might have an answer for you on how does that wing come over if all of its lift has been dumped. See usually you do a snap roll the way the engine torque is pulling. Which is usually to the left so you usually do a snap roll to the left. That really actually forces that wing with no lift to come over. Because the torque of the engine is pulling it.

      Regards. Two comments. 
      Snap characteristics are independent of scale. The only thing that changes is the clock ( due to changes in moments of inertia ). 
      When the rudder is applied it is the outboard wing that exceeds the stall AOA and dumps. Actually it is not much of a lift dump but a huge jump in drag.
    Nat true. Moments of inertia are design parameters. So are several other key parameters that may make or break a model's ability to perform snaps. That was my point.

    I agree in terms of AOA (outboard aileron low) and drag increase but I am not as sure regards to lift. I know what you are saying though. 

    One question: how does the outboard panel lift over the top if its lift has been dumped?
