Default Super stretched -6

For those of you who don't belong to EAA or receive Sport Aviaition, there is a story about a stretched RV 6 with an IO-540 making 299 HP. The airplane also has two rearward facing seats. It's been "cleaned up" and cruises at 225 MPH!

I'm thinking it would be quite interesting to see a -10 turned into a 6-place, there are quite a few high-output engine options that could be used for that.

Thanks for those Pics Pierre. And your right, true experimenting. I love it. Im guessing he has the tip up mod to get someone in there. Also based on my experience with the Super 7, and the fact that he did not move the front seating arrangement, that he would likely fly it with some weight back there.

In the Super 8, the pax is not a factor since I have the fwd baggage to be able to shift some weight around. But in the 7, that would be my guess.

If I remember correctly, Carl claims over 300 HP. He ran the AirVenture Cup race to Oshkosh with us last year. Very nice people.

He beat me by 10 knots last year...he better watch out this year!

Default He started with a flying airplane

I read the article last night. The plane is out of the Harmon Rocket camp. It is around 20 inches longer than a standard "6" so the CG has been taken into consideration in the building of the airplane. I noticed a very long center rail for the canopy so accommodation of the rear facing passenger entry and exit appears to have been considered. He bought the plane in the 4-place airframe configuration They make a big point of the effect of the landing gear and wing tip configuration on speed. The statement that the change he made to the wingtips were expected to add 7 mph to the speed but the actual result is not provided - I don't believe it for an instant. The 299 hp IO-540 with special induction and prop are big factors in the 225 kt speed I believe.

The wings on that plane have also been clipped. A special spacer is put in place to get back the missing span. Also the fuel tank goes all the way out to the wing tip. I wouldn't sit in the back of that thing if my life depended on it. The extra two seats are not really meant for adults. You might be able to talk some kids into ridding back there.

I think even a stretch RV-10, with an additional 12 inches with an increase in gross would be great!

Default I know that plane!

I happen to know a little about that plane, although I've never personally seen it. It was built by a couple of EAA Chapter 10 guys at Gundys airpark, in Owasso, OK. That was my old chapter in when I was in Tulsa. The plane was featured in Kitplane the year it was finished (sometime in the mid-90's). The pages were framed and still hang in the chapter hangar. It looked exactly the same except for the flame job. If you look close, you can tell the flames were added later.

If the name John Nys sounds familiar, it's because he was also the first guy to finish an RV10. On that day, he probably had more four place RV experience than the factory. You've got to wonder why the article didn't mention something about it.

I also don't remember anyone ever saying anything about it being based on the Harmon Rocket. They called it the "Super Six". My understanding was that it started life as a standard RV6 kit and the guys did the engineering themselves.

Anybody from Chapter 10 who was around at the time and knows the real story?

Default Super 6

This extra long over Horsepowered RV-6 was from what I know,,,,, was built in Oklahoma and actually flew out to my familys private landing strip many years ago (OK39) The original owner made most of the mods and yes it had a Six Banger engine in it then. The original owner later sold it and the new owner from what I know made many more changes after I met him at Okskosh 06. Here are a few pictures.

Default Canopy tilt......

Thanks Alan,
I noticed that the rear rails hinge upward to allow ingress/egress for the backseaters. Did you happen to look closely at the detail? Seems like the canopy hits a stop and then the rear rail is raised. Be neat to make it easier to access rear baggage on a standard slider as well. How many of you guys have the Meske (sp) system? Like it?

Regards,
Pierre
