Snap G's

[Grow Pattern]

If the 404 snap is positioned correctly, in the reverse avalanche, it actually begins before the plane reaches the bottom of the loop. I wonder what the G reading might be if you go a bit too early?

My planes flew both FAI 1.5 horizontal snap with no problems. Then I flew a bunch of reverse avalanches and hey presto! problems.

The only other avalanche with a snap on the bottom is in the F-05 schedule. You might say that they are having no problems with the maneuver. Then you might just consider how many pilots fly F-05 and then compare that small number with how many will fly 404 this year!

You may well, and many have, that I am not flying the maneuver correctly, or that my planes are not built right or even designed properly. You may not say the you were not warned!


Regards,

Eric.

  Speed is the governing factor, since the model's inertia is what changes in a snap. A loop generates maybe a couple G due to pitch action alone, and it should be additive to that induced by the snap. 

  I find it curious but reasonable that the accelerometer indicated the same value for both a snap at the bottom of a loop as well as one done at S&L. Two distinct maneuvers done at different times.

  Wonder how many G's the Wall, Blender or Parachute stunts generate?

    So, if I am interpreting these numbers(realize only one day and flight) correctly.  Beings the straight and level pos snap at 100mph(not unusual speed) was -13G's and the Rev avalance at approximately 95mph was -13G's, then the forces are about the same.  

    So, if we can slow the rev avalanche down to 70mph then the G's would only be -7.  

    This seems to go along with previous arguments that speed is the key.

    My question is, if the G's on flat and level snaps are approximately the same, with approx equal speeds, as the rev snap, then why hasn't FAI pilots been breaking planes with the 1.5snapopp 4/8????  

    Before anyone says it, I have seen many of these 1.5 snaps flown with some speed, so they weren't just puttputt into it.

    Thanx Earl.  Interesting stuff
