Then my hangar mate installed them on his Pelican and it reduced his flaps up stall speed from 60 MPH to 46 MPH with 400 pounds of pilot and passenger. So I decided to try the ones he used. They are Stolspeed VGs. They are flexible plastic and are very easy to attach and remove should the need arise. It took me two hours to install them on the wing. On the test flight I noticed the same as with the other two brands. With flaps full down (10 degrees on my Avid) there was only a very slight reduction in IAS which could be AOA error. However, I kept the VGs on and soon noticed, after flying several more hours that, while my flaps down stall didn't change much, my flaps at neutral stall speed dropped from 46 MPH IAS to 41 MPH IAS so that there was little difference in flaps off and on stall speed. Then I noticed that my typical climb rate increased by 200 FPM and my glide ratio improved. I fly a lot of back country strips and the VGs will help in getting me into and out of the more challanging strips in Idaho. Full power stall with a Jabiru 2200, Tennessee 64 x 36 2 blade prop and 10 degrees flap is 29 MPH IND. Idle stall with flaps is 39 MPH IND. These VGs were only $100 bucks and I consider the cost worth while.

One question I have while reading the plans, I don't see how y ou space the inboard pedal so the 2 bolts holding the adjustable pedal contr ol wheels do not contact each other. It seems that the bolt heads will hit a fter you install the plastic bushings and drill the assembly to keep your 1/ 32" side to side clearance. What am I missing? Picture attached. Thanks -Mike Kraus RV-4 sold :-( RV-10 flying :-) KitFox SS7 Radial building :-)
