F3A - snap roll query

[Rcmaster199 at aol.com]

Marty,
Do you mean "one wing panel" is stalled? Most of us are flying planes with 
"one wing". 

I agree with the "one wing panel is stalled" concept and in fact, you may 
recall that Earl talked about this same thing about 3 months ago in these 
pages.That has to occur for a snap roll to occur. If correct amount of elevator is 
added a split second before the other commands, the snap is far easier and 
cleaner to perfrom. The wing panel with the "up" aileron, stalls far quicker, 
making for a cleaner, easier to control snap. The trick is in the amount and speed 
of elevator input. The fastest possible input would stall the wing far 
quicker, even for small elevator volume. The nose will pitch, but as Don sez, the cg  
should not. BTW the Judging tape shows the nose pitch before the roll, quite 
clearly

It sounds that some of the responders think that elevator isn't needed. Well, 
just try to make a snap roll with aileron and rudder only. Nat Penton's 
XPRESS 3D may be about the only plane that has that capability.
