In my ultimate quest for a STOL airplane, I built a Just Aircraft Highlander and replaced the standard wing with a Riblett GA 30-613.5 and added a moveable leading edge slat and full span 30% cord flaperons. This aircraft has a 912S 100 hp engine. I currently have about 65 hours on my airplane and I am happy with the STOL capabilities as well as the 105 mile an hour cruise speed (with the 29" Bush Wheels). However, I am now thinking about building another set of wings to (occationally) replace the set that I currently have on the plane. I am thinking about going with the Riblett GA 35 A 412, an entry level laminar flow wing. My question is, if I kept everything the same (54" cord, 150 square feet, Bush Wheels, etc.) what could I expect for an increase in cruise speed? I would not do a leading edge slat and would do a 10' slotted flap with 4' deep cord ailerons instead of the full span flaperon. I would eventually take the Bush Wheels off for higher cruise with this wing, but I am curious about the apples to apples comparison between the two sets of wings. I have been told that my stall speed and my cruise speed would increase by about 10 miles per hour. Does anybody have any thoughts about this build?
