Rudder Turbulator Strips

[Tony Quist]

Jim,  That is correct.  The wide trailing edge will dampen the yaw
around neutral.  This also works on the trailing edge of elevator and
wings.  If you ever look at a Carden aircraft you will see a trailing
edge that is 3 time thicker then other brands.

This is also going to be on of the changes on the focus 2.  they are
putting on a thicker rudder.

I thought I read about 2 years ago that J.S. put a split piece of fuel
tubing on the TE of his 33 or 40% fiberclassics airplane's rudder to get
rid
of a tail shake or something like that?

Hi Wojtek,

Not "turbulator strips" as such, but:
I saw a rudder on an Austrailian 2 meter bird at the 
NATS years ago with a very thick trailing edge.  
The pilot (I don't recall his name) said it provided
better response at low speed- such as stall turns.
I suppose you could tape a triangle about 1/2" wide,
1/8" thick to each side of rudder to create a 
trailing edge about 1/4 to 3/8" thick to try it.
If you do, let us know results.

Later, Ron Lockhart
