wing tip shape (now surface hinging)

[Rcmaster199 at aol.com]

NO!!! REALLY???? GEEZ I DIDN'T KNOW THAT (jus' kiddin' Keith, and pokin' a  
little fun)
 
With the kind of geewhiz programmability available nowadays, too many of us  
have become a little complacent and use the electronic fixes as cure alls. I 
am  old school and prefer to make the mechanical set-up as sound as possible 
first,  then use the radio to trim the mechanical set-up if needed. If it needs  
more than a few percent electronic fixing, I usually re-do the mechanical 
set-up  in my pattern models. I do not subscribe to electronic fixes for 
everything!  (Sport planes are another matter)
 
Having to electronically fix knife edge flight for example, just frosts me,  
particularly when a kit costs over $1000 in some cases.

Assuming the use of a computer radio, it's easy to program the throws in  the 
radio to make sure they're symmetrical.

Ted, in my experience it makes no difference as long as the horn is  located 
correctly to produce symmetrical throw top and bottom. More  difficult to do 
that with a top hinged surface than a center hinged surface,  so be aware of 
this pitfall. Yet, the top hinged surface is much easier to  seal than a center 
hinged surface, so there are always compromises in  everything we do. 
 
Personally, I always center hinge my surfaces.

For  appearance sake, I had planned to top hinge them.  I take it from the  
discussion,  that the way the surface is hinged has no noticeable  effect in 
flight – provided the gap is sealed? Correct?
