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. If you are interested,
visit Stolspeed.com for more information.

Thanx all that info on VG's. Who suggested putting them in the trailing edge of
the hor. stab?

| Subject: | FlagFly heel brake improvement |
G'day Kolb drivers,
I did a mod to my Matco heel brakes on my FlagFly that turned out to be
one of those YES!!! moments. 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.

BTW, Don G. put VGs on the underside of the horiz stab on my FlagFly,
and although I don't know how it would handle without, it flies so great
with them I wouldn't change a thing!!

Hello Gerry,
What I could show you in a picture installed could be seen better by
going to homedepot.com and putting either of these two identifiers in
the search box:
Model # PQC-101 Store SKU # 688053 Since the cap is made to
slide over PVC pipe, picture a shorter piece of pipe inside and the
remaining depth slid over the brake pedals, then tightened in place with
the clamp. 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.
Dave Kulp

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.
