Jim,

No offense, quit whining . . . have you considered Lefty Aversion Therapy?

We used to have a "don't ask don't tell" policy here at Bumper Soaring (or BS for short). Under intense political pressure, we had to end that. We still do our best to force all MKIV's from the same mold, ambidextrous and "straight". Unfortunately, we've noted a few with left leaning tendancies, some mostly go to the right, and nearly all, if given half an opportunity, will quite happily go both ways.

Yes, it's a source of embarrasement for us and for some MKIV owners. You may even notice in YouTube videos that many of these same owners will carefully edit out any shots where their MKIV is, um, wildly playing the field so to speak.

How typical. It's always OUR problem. We've learned to live in a right
handed world. Is it really to much to ask for you to consider our
plight? You're probably against lefties marrying each other too.

I had no idea what you are going though. A quick search found http://www.cracked.com/article_19808...-you-life.html

Do you fling cats at passers by? Should lefties be allowed to marry at all?

Hi bumper, I am the Schweizer driver at the airport. With great interest I read the many sophisticated suggestions, but I fear they miss the most basic improvement needed. Your instrument gets right up in the pilots face with constant criticism. I get enough of that at home.

This is not all tongue in cheek. You may have noticed I have no instruments for just this reason. However as you are the most innovative builder perhaps you could come up with something with positive reinforcement. I am thinking pneumatic. ;-)

xcnick,

I'm sure it can be done pneumatically, and fairly simply too. Something like two ports, one on each side of a forward facing vane, the port openings lateral to the ship's axis to avoid ram air. With no yaw, delta-p on ports is equal. With any yaw, delta-p increases.

Display could be analog, digital, or audio.

However, this yaw indicator would violate the KISS rule. More complexity for little or no gain in functionality over a yaw string.

It's also done with a slip or skid bank indicator ball, used in powe planes where prop wash precludes the use of a yaw string. http://www.aircraftspruce.com/pages/...nk_indicat.php
Though I think a yaw string is more sensitive than most ball indicators I've flown with - - plus you don't have to look at the panel to read the yaw string.
