When I had a Nuance with a full flying stab it was so responsive I had it dialed down to 8 degrees by the time I had it trimmed out. And I found the radii could get sharp pretty fast so I had about 20% more expo programmed as well. Definitely more surface area makes a big difference. The nice thing is that once initial incidence is set, you adjust using elevator trim rather than incidence adjusters.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Hope that helps,</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">John</div><div><br></div>

I understand that there are many variables including size of the stab, CG, AC, etc. but I'm looking to give them a place to start. I was thinking of the Bi-Side and wondering if someone could give me, in degrees, the amount of travel for the stab so that we have a starting point. I'm sure I'll have fun with the maiden but, hopefully, we will be in the ballpark.</div><div class="ydp7f9f35f4yiv2418237503gmail_default" style="font-family:georgia, serif;color:rgb(153,153,230);"><br></div><div class="ydp7f9f35f4yiv2418237503gmail_default" style="font-family:georgia, serif;color:rgb(153,153,230);">Thanks!</div><div class="ydp7f9f35f4yiv2418237503gmail_default" style="font-family:georgia, serif;color:rgb(153,153,230);">Scott</div><div class="ydp7f9f35f4yiv2418237503gmail_default" style="font-family:georgia, serif;color:rgb(153,153,230);"><br></div><div><div dir="ltr" class="ydp7f9f35f4yiv2418237503gmail_signature"><div dir="ltr"><div><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><b style="color:rgb(153,153,230);"><font style="font-family:comic sans ms, sans-serif;" size="4">Scott A.
