<p>Duane, </p>
<p>My slats weighed 14 lbs (painted) and after recalculating the CG, it only shifted on average about 5mm forward. This must be pretty accurate as there are no noticeable trim changes with/without slats! As I recall, the datum is taken off the leading edge of the slats, so, to make any future measurements easier when slats are removed, I referenced that datum to the distance forward of the center of the main gear wheels, which was 760 mm forward in my case.</p>

<p>If you've followed my other posts, you'll probably know that I recommend the Stolspeed VG's if slats are removed - very little difference in takeoff and landing roll but you can't get quite as steep approach and departure angles.</p>

I am well into a 750 STOL project I took over. Original builder did not want slats and closed in the wings without the mounts for them. I plan to complete the project without slats and have followed your earlier postings of flying without them. Can you give me any insight on CG differences and calculations?

<p>I am in the same place as Bob! I do however want to sincerely thank John Austin and Jonathan Fay for sharing their experiences and expertise. Still a tough choice, but their posts are very much helpful. </p>

<p><span style="font-size: 8pt;"><span style="font-size: 10pt;">The stub brackets have no adverse effects. Since the intermediate brackets restore the slats to their original position, no problems when slats are installed. I'm quite satisfied with either configuration!</span></span></p>

<p>We have the slats removed from our 801, and we were just discussing whether to make it a permanent decision and cut and grind off the brackets, or not. I like your idea of leaving a shorter bracket "stub" and using an intermediate if we want to add them back. We were debating how much difference it would make in performance, or would it be just an aesthetic change. Any insight on your thinking and experience with the brackets would be appreciated!</p>

<p>I have a new topic. I broke off a corner of my windscreen and rather than spend $1,000 for a new one, I would like to make a new one. Has anyone done this in the shape of the usual windscreen? Has anyone made a three piece custom screen? </p>

<p>Was once going to build mine as a "STuzer" too, then decided probably not. Now I can firmly say, with pride, that I'm entirely unsure what I'm going to do.</p>
