[NSRCA-discussion] [F3A-Discussion] snaps

[Bob Richards]

Ken, I agree with you 100%.
 
While flying for some video that Fred Midgett was shooting, I had the opportunity to do some snap rolls flying directly towards the camera. This was an electric Cap 232 with a relatively high wing loading, and it snapped very well. But, when flown directly towards the camera during a snap roll, it obviously displaced in a corkscrew fashion during the snap. 
 
I've said it before (and so have many others) that the wing, even when stalled, is still generating lift. I say it is impossible to do a snap roll with the CG traveling on a straight line. I'll challenge anyone to shoot a video of the plane traveling directly towards or away from the camera, do a snap roll, and show us that it remains on a straight line.
 
Just M2CW.
 
Bob R.

Dave et all,
 
I am having a bit of trouble understanding how a plane in forward motion can with 100% certainty rotate on it's CG...when the tail drops or raises, depending on Pos or Neg snap, the nose goes the opposite direction. I just don't see how you can stop the CG from moving at all, even the slightest bit would be a downgrade.
 
What I think would be very cool is. we get a vid of what we all would consider as perfect a snap as we've ever seen and generate a line as an overlay to represent the track...extend that line forward of the planes position, then we will be able to see if there is an actual deviation of flight track or path...
 
I think I'm living in a dream world...LOL!
 
Ken
