<p>Tom,</p>
<p>Here is an RCU thread that goes through some of the various
methods of rudder power enhancement. Bryan Hebert will tell you
and show you that all those appendages are unnecessary with proper
design. His website at ckaero.com also has info on this subject.<br>

<p>I would like to get back to your part of the world for another
visit. So far, retirement keeps getting in the way.<br>

Cheers,<br>

<p class="MsoNormal"><span

would appreciate some feedback on the whole topic of all
these appendages that seem to be hanging off the current
generation of pattern planes these days. Quite frankly, the
purpose of which has me scratching my head.<o:p></o:p></span></p>
<p class="MsoNormal"><span
style="font-size:10.0pt;font-family:"Arial","sans-serif"">I
am currently in the midst of designing a new model, with
which I wish to return to flying and competing. One of my
parameters is that anyone should be able to build it from
plans, should they chose to do so-and it must reflect
current lines and complex shapes-but must meet aerodynamic
parameters/requirements first. It will be a challenge-but it
can be done.<o:p></o:p></span></p>

<p class="MsoNormal"><span

just why do we have all this garbage hanging off planes? Are
they fixing simple design deficiencies or are we purposely
re directing airflows to achieve what?<o:p></o:p></span></p>
