<DIV></DIV>
<DIV><FONT face=Arial size=2>FWIW, I took a quick look at some snap G's
yesterday. Equipment was a Quique YAK (140 size) fitted with an Eagle Tree
Systems datalogger with G sensor. I only gathered data from one flight - so take
that into consideration.</FONT></DIV>

<DIV><FONT face=Arial size=2>Flat and level pos snaps @ (nominally) 100mph
= 13G, dropping the speed to 70mph = 7G. (A normal pull to vertical @ 100mph =
7G.)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>An Avalanche with a neg snap at the top measured
-5G @ 50mph.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>A Rev Avalanche with a pos snap at the bottom
measured 13G @ 95mph. (Masters maneuver - intentionally flown
fast.)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>An Avalanche from the top (push - F05) with a neg
snap and a half at the bottom measured -14G @ 90mph. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>(I normally measure around 5G on upline and
downline snaps with my Partner.)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>All snaps were executed with rapid / high degree
elevator lead and % reduction of elevator during rotation.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I may look at this further as the mood
strikes. As expected, controlling speed into snaps is easier on your
airplane. None of the observed loads (in my opinion) should damage a well
constructed aerobatic model (wouldn't want to ride in it though).</FONT></DIV>
