6 to 7 Model differences

[QuiQuog]

Can someone help define the differences between a KF6 and a Super Sport? I've only found information that says vaguely that some things have been improved. They look the same to me, but I know there's more to the story. I seem to remember reading that if you put the SS wings on a 6, it's basically a 7. It's likely that I'm not remembering correctly though.

I have a 5,
but a few 6 to 7 SS differences that come to mind are ;

the firewall forward , engine mount puts engine out approx 4" further from firewall = extra room for maintenance

there is a boot cowl that can be sealed nicely to the firewall

larger elevator , about 4''

I believe the 7 SS control rod for the elevator has a pivot in it that is a little different than the 6

the 7 SS is built light , and registered at 1320 gross instead of the 6 at 1550 gross

The SS7 can still be registered at 1550 gross. I think the 6 has a trim tab instead of a movable stabilizer. Also, I think the wing is the exact same for models 5 through SS7

the 7 is 1320 gw on regular gear but 1550 on optional (grove) gear. The 6 has an electric trim on the horizontal stabilizer and the wing is different on the 7, I just can't remember what is different about it. I am still building a 6.

The wing rib profile has been the same since the four, all the way through the SS.

I think the 6 has a trim tab instead of a movable stabilizer.

My 6 has stabilizer trim not a tab. I think it was the early 7s that had the trim tab. Maybe late 6s though.

I don't think the 7 ever had a tab. The 5s did though.

The later 7's added a top fuse razorback, the Laker leading edge wing option, and a much improved seat mounting system using weld tabs and screws rather than zip ties.

I don't think the 7 ever had a tab. The 5s did though.
My 5 has electric stabilizer trim , I think there were options for a manual trim tab eventually in the line. I looked at a 7 that had a manual trim tab. A builder's decision for sure.

I am not 100% certain but I think I remember there was a time Kitfox could not get the jack screw and there was a manual trim with a tab. I am sure it was after my Model 6 that I ever saw one with a tab.

I believe initially the 7 came with the tab (mine did) the SS reintroduced the electric jackscrew (which I upgraded to)

Interesting......
From the Series 6.. There was the Series 7, Sport, Series 7A and now the Series 7 Super Sport and the Series 7 Light Sport (SLSA).
The elevator anti-servo trim tab was first introduced in the early Series 7.. the first few S7's were the original electric trim stabilizer. Manual trim was on the Sport and the 7A.It was sold as aftermarket as well and many changed their 5 or 6 to the manual trim tab.

There are many differences from the 6 to the S7-SS. Flaperon and Flaperon mounting is different, Firewall forward was not only for maintenance, but for balance, more use of the cargo bay and the ability to seal the windshield to the firewall. Cargo bay is larger, push-pull control system is different, seat pans are different, many minor changes within the fuselage, larger elevator, different wing tips, razor back with antenna plate, different fuel tanks. There are more options available like the LLE..

Structurally: All 1550 max gross capable except the SPORT.

Many other items that are more manufacturing related and would go un-noticed.

I was hoping the guy that really knows would answer! :)

Right from the horse's mouth. Thanks John!
And everyone else, of course.
