[NSRCA-discussion] Thick trailing edges

[jivey61 at bellsouth.net]

 I isn't a fad. It actually works. On my Phaseone pattern plane, I split the
ailerons lengthwise and inserted thin triangle stock piece of balsa. This
made the ailerons about 3/8 inch thick.
The result was a very soft feel around neutral.When the ailerons were
deflected the turbulance off the aileron decreased and the sensitivity came
back.The full travel sensitivity stayed the same. The snaps became very
predictable,the point rolls were very easy to stop on points,because as the
plane went through this soft phase at neutral it actually slowed to the
stop.
I exaggerated the thickness so I could readily see a change,and I did.
I only did this on the ailerons,but it could be done on the elevator and
rudder. Matter of fact it is done in IMAC quite a bit on the rudder.
