I learned a long time ago that by coupling flaps to
ailerons the model would track better. (And yes, every
model) My first experience with this was with a slope
racer (Swift 800) with a short tail moment, and
undersized V-tail. I had trouble getting it to track
properly at different ballasted
Now I'm really confused, even though I know the 'right' answer. I had a
very good flyer sell me on the opposite - just ailerons for turning,
keeping the center section of the wing 'clean'.
I'm torn here - leverage really favors the outer surface, how much do
you really get from the flap help?
Brent,
The wonderful thing about this hobby is that you don't have to
believe anyone! Give the options a personal flight test and decide
for yourself what you like the best. Aircraft design theory is a
wonderful thing but in the end what you are able to demonstrate for
yourself needs to be

If you are worried about keeping the wing clean, put in more dihedral
and use rudder only.
If you factor in bad designs and bad airfoils, there is definitely no
one 'right' answer.

If I couple the flaps and ailerons I like to use them 100%. the
Roll rate is increased and to be honest I can't feel the extra
drag. This flies in the face of conventional wisdom but its what
I like... one big flaperon...

I saved this post from Dr. Drela from October 2003; it's long but
very good. Since he originally posted it to the exchange, I'm
presuming a repost is OK.
