<DIV><FONT face=Arial size=2>Sorry for the delayed response. I would like to
point out the slipstream effect on the empennage is more of a steady state
nature, whereas the aileron effects are instantaneously
disruptive.

<DIV><FONT face=Arial size=2>Nat and Peter,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I differ on this. I've built 3 sets of test
wings on an Aries with 20, 22, 24" ailerons. The idea was to see if I
could get more aileron effectiveness while flying at a slower pace on
uplines. this is where airspeed is lower and ailerons lose
effectiveness. The thought is to catch some of the prop blast to boost
effectiveness and give a more consistent feel.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>It works well. Do not be concerned about
longer ailerons affecting airflow over the stab. The swirling propstream
does far more damage. On the Symphony I found 22" to be my favorite and
I've updated the kit. On the Aries, 24" seems to work best.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>It sure is great to be able to continuously
improve a good desing into a great one. Every time you start over with a
new plane there's a whole new learning curve.</FONT></DIV>

- there is no reason not to stop the aileron about even with the

has ailerons which extend a fair way towards the fuselage (Comp-ARF
IMPACT) What effect does the turbulence coming off the aileron have on the
tail plane. I am currently building another IMPACT (IMHO flies extremely
well) which I am considering to reduce their size by cutting and fixing
the inboard part to the wing in an attempt to clean up the airflow over
the tail plane during rolling maneuvers . The model does roll well
but it could be better.<o:p></o:p></SPAN></FONT></P>
