intermediate 402 rolling suggestions

[Ron Lockhart]

Let me suggest an alternative and more subtle approach-

Start feeding in a tiny bit of down elevator as the
plane has rolled about 135 degrees, by the time the
plane gets to 180 degrees have in as much elevator as
it takes to be level inverted or a touch nose high.  
As plane passes through 180 degrees of roll, start 
taking out the down elevator so that it gone at 
about 225 degrees of roll.  

And maybe a secret - Use some "up" elvator.  
As plane completes about 315 degrees of
roll, start adding a tiny bit of up elevator increasing
gradually so that when plane finishes 360 degrees of
roll, nose is a touch higher than level to correct for
the nose down attitude it may have gotten during the roll.
Get out of the up elevator by the time the plane is
45 degrees into the second roll.   

Practice a couple of mistakes high.

Whew.  It could be worse.  A couple of years ago the 
maneuver was "three" consecutive rolls.

Later,  Ron Lockhart
