Why would you let something as trivial as mathematics (or physics) get in your way?<br><br><div class="gmail_quote">On Sat, Feb 27, 2010 at 8:21 PM, Ron Van Putte <span dir="ltr"><<a href="mailto:vanputte@cox.net">vanputte@cox.net</a>></span> wrote:<br>

A full scale friend lent me a book by Alan Cassidy entitled “Better Aerobatics” which had a formula for determining how many Gs to pull to enter a snap. It is very enlightening.<br>
<br>
<br>
<br>
Formula is = Recommended entry speed to enter snap divided by the Power ON stall speed - Squared.<br>
<br>
<br>
<br>
His example (Pits S2A) was 105/55 =1.909 (1.909)2 =3.64 Gs. This means you would try to have an instantaneous 3.64 G loading if entering the “flick roll” at 105 mph.<br>
<br>
<br>
<br>
What I find fascinating about the formula is the “power on stall” part of the formula. Now translate that into our models which have NO power ON stall speed. I think this means that mathematically we cannot do a snap. Or the instantaneous Gs required are impossible to obtain.<br>
