Does anyone have a picture or two of a IV with the speedster fairings? What I'm looking for is how to finish the bottom fuselage around the rear tail spring attachment. That area is very busy. If the bracket wasn't there the natural way would be to lay fabric around the bottom and then over the rudder fairing. The bolts that hold the tail-spring need the area above the bracket clear in order to insert them - there isn't enough clearance there to spin a nut and the bolt is under too much side-load to turn it from beneath.
My manual shows the KF V and a VI w/o the fairings there. Would like to see what others have done.
Here is a photo of the bottom of our 7 with the fairing and fabric in place. Don't know of the IV has a different placement for the attach holes for the tailspring/tailskid. On this one - the front bolt is tightened from inside and outside the fuse frame. The two rear bolts are have access to both ends of the bolt from the outside.
You wouldn't have a close up would you?
I'm going to have a look at another KF IV speedster this coming weekend. Hope for a ride but if nothing else will take some close ups of that area.
I don't have a close-up; however if you would like to let me know what your personal e-mail address is via a PM (private message) I can send you the original full size photo which you can scroll into to see the detail you are looking for on your image software.
Yeah, that is a lot different than the KF IV Speedster arrangement. So on yours the bolts for the tail-spring have to come up and the nuts are in pocket between the bracket and the fuse bottom.
On my IV (and the III) there isn't room for a nut to turn or even a washer in that location. The holes place one of the bolt head facets hard up against the frame tube/weld. The bolts hang down and the nuts are tightened underneath. The bolts are also under some side-load from the spring/spacer so that turning the bolt would be pretty hard.
What I have at the moment is a "relief" hole in the wood rib above it so the bolt head can be lifted up and then dropped into the bracket. But there doesn't look like there is a good way fair it in. I guess I could fabricate something from filler and fiberglass but it would need to be tough enough to survive down there in the grass and stuff.
I have no recollection of how I did mine, but I will look for some pics tonight and post if I have any. A picture in its current state may not help you, but I will try. Sorry i didn't chime in earlier.
Mark,
I went out the airport today to do some things fully planning on taking a picture or two of my Model IV tailpost. My fairings are home brew, but essentially what I did is cut semicircular holes at the bottom - each side - and convered. The fabric caved in a bit at the cutouts and I was able to squeeze the nut in from each side. If I can remember to take the pictures tomorrow, I will drop another note with pic.

.....here is a photo I found after some digging which is after paint/pre covering of the bottom of the tailpost.
