Hankins" I finally got the STOL Speed VG's installed on my Firestar KXP. They are a lot less obtrusive than the homemade ones and look a lot better. I went out and put the firestar through it's paces after the install and am very happy with the results. I installed 105 VG's on the wings and 20 on the underside of the horizontal stabilizer trailing edge (10 per side). Larry Cottrell added VG's to his elevator and recommended I try it. The results were positive. I have more elevator authority (didn't feel lacking before, but it is awesome now),a slighly slower stall speed compared to the home made VG's and a more gentle stall. I flew lots of power off stalls, power on mushes (it won't stall at full power) and tight turns in both directions 'til I was dizzy. Suffice it to say that I have gone to the dark side. I was OK with VG's before, but now I'm a true believer. The STOL-speed VG's look better than my home made versions, and the results are a bit better as well. Power off stall speed went down slightly from 34 to 32mph indicated, but control authority in the elevator and ailerons was noticeably better. Part of the improvement, I think, is due to having VG's installed all the way out to the wing tips and using closer spacing out at the tips. I can hold the firestar in a stall now without one wing wanting to drop. This is how it performed before any VG's were installed. The homemade VG's made this a bit worse, kind of like balancing on a ball. With the Stolspeed VG's I have my original Firestar handling back, but with the lower stall speed of VG's. The differences aren't huge, but they are definitely noticeable and positive.

Reaching for my brakes required a very unnatural thrusting my heels forward all the while trying to steer with the rudder pedal. The way my knees are bent while sitting in the FF made it a difficult thing to do. So I went about trying to improve the situation. First I cut two 3/4" lengths from a large dowel, shaped the one side concave to match the brake pedals, and epoxied them to the pedals. Felt a lot better in use, but in a short time one of them came off, so I removed the other one, too. Flew that way for a while, but still wanted to do a more permanent fix, so I hunted through my "stuff" and found that the diameter of the brake pedals is just slightly larger than the OD of 1 1/2" PVC. I trucked over to Home Depot and browsed through related items to try to find something which would fit over the pedals and not have to be glued on. And there they were; rubber end caps with hose clamps to cap off an inch and a half PVC pipe. Bought two and brought them home. Measured the inside depth and cut two pieces of inch and a half PVC pipe about 3/16" shorter, using my radial arm saw in order to get a perfectly square cut. I pushed the pieces of PVC into the end caps, moved the clamp flush to the edge, and pushed them onto the brake pedals. Tightening the clamps then compresses the edge of the rubber cap nicely around the edge of the pedal while the downward force is transmitted from your heel to the pedal via the PVC pipe. A very solid function. I checked for any conflicts from the screw mechanism on the clamps and finding none, climbed in and worked the brakes and rudders. Not only does it allow my foot to position perfectly, the rubber creates a slip-proof surface, like the brake pedal in your car. So, if anyone else has the same annoying foot position with your heel brakes, maybe you can give this a try. About five bucks and fifteen minutes is all it takes.

You'll see they have the clamp positioned about 3/16" from the edge but you'd want to slide the clamp to be flush with the edge since that's what is going to compress around the perimeter of the pedal to hold it in place. The face of the cap is the surface your heel pushes on when braking, and inside is a piece of PVC pipe resting solidly on the pedal. Hope this helps.

Hankins" Well I guess I could have been more specific in my first post. I said that Larry had put VG's on his elevators. What I meant is that he put them on the underside trailing edge of his horizontal stabilizer, which is the correct location if one is trying to increase elevator authority in the nose up direction. As I said, he recommended them and now that I have tried them, I can see why he did. -------- Roger in Oregon 1992 KXP 503 - N1782C Read this topic online here: http://forums.matronics.com/viewtopic.php?p=382717#382717 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message kolb-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Kolb-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/kolb-list Browse Digests http://www.matronics.com/digest/kolb-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
