Just curious, why would you remove the Horton STOL Kit and install a different type. Is there really a noticeable difference?? Is there 10-15 knots difference in stall speed or is it only 1-3 knots??? Seems like a lot of time and money for such a small result. Just asking, maybe something I do not know??
BTW, very nice airplane, can't wait to see it in the air. Not trying to be negative, just wondering.
I must admit, the Horton was and is a very good STOL kit. I too am very interested in seeing the true outcome. I flown with a lot of cub guys (many we know on here) and my 180 ALMOST kept up.
From a lot of research (I can tell you I have not flown a Sportsman) all the facts show that its the very best STOl kit out there. If I can shave 3-5 knts off on landing, that can be significant on roll out. Same goes for the take off.
I like what Sparky writes here:
Landing Speed, Landing Distance:
A 10 percent increase in touchdown speed equals a 21 percent increase in landing distance.
Here is the entire read. Its pretty good. http://www.mountainflying.com/Pages/mountain-flying/rule_of_thumb.html
At 6000' my plane could honestly stop in about 200' or less very easily. For me I am looking for the ultimate combination for the 180. If 2-3 or 5 plus kts is taken off, thats what I am after.
The leadind edge on a Sportmans is also significantly different. The Sportsman cuff is much more aggressive, and lowers the stall speed significantly. The Bush or Horton kits have a much smaller cuff, and less performance increase.

This is a real good diagram for comparison. After removing the Horton, I can support these diagrams now.http://www.steneaviation.com/sportsman_stol_comparison.asp?menuID=7~7
Ultimatly the Sportsman with the Wing X combination gives, you get a significant amount of wing area. I spend a lot of time on the Skywagon email list asking questions to those with thousands of hours and have flown both. All replies come back and support the Sportsman. I guess my long story short is, I will tell you more once I fly her because all I have now is hear say and others supporting it.
Very good question for certain.
The other reason...when I put the bird on her nose with my tail up taxi pracitce, I dinged up the right wing slightly. So, it was repair the Horton or change it up. I have wanted the Wing X for sometime (for the uefull load increase). The Wing X and Sportsman seems to me, the ultimate combo. Who knows, I may end up with the Horton down the road again but I am betting this set up is going to be real good with the new big engine.
I am now questioning whether I should put the micro VG's back on. Thinking I am going to fly her without them at first and see what kind of aurthority I get at a real high AOA and very slow speed. Betting I am going to want them back on. When under the horizontal you help the Aileron authortiy big time with the Horton. Hearing the same about the Sportsman.
We are getting close
