KR> Tandem seating PT II

[dustin Reves]

Did this so it would be easier to read

OK after thinking about the tandem seating Idea for a few days I feel
like it  will be a little bit harder than I thought it would... But
based on my limited knowledge of aerodynamics, and a few basic
assumptions, this might still be worthwhile. Obviously I would like to
get the maximum performance out of my project that I can. There are 2
reasons that I am fixated on the tandem seating arrangement. 

1.
I feel like the decreased width of the airplane will benefit in making
it as slippery as possible. obviously something 44" wide is gonna be
harder to push through the air than something 30 inches wide.

2.
The tandem seating just feels sporty to me. Much more like sitting in a
fighter plane than a cross country cruiser. Well, doesnt everybody
wanna feel like they are flying a fighter?

The drawbacks are the
rather large adjustments that will have to be made to the airframe. Im
thinking the wing will have to be moved  back. The front passenger will
have to sit somewhere right on top of the foreward spar. while the
pilot (rear) will basically be sitting  directly on the trailing edge
of the wing. I havent done the math(nor do I know how to ) but this is
definately going to necessitate moving the firewall foreward. If I
follow the suggestions of previous builders(Mark L) and use the full
length of longeron material provided in the boat kit I think I will
have enough material to massage the dimensions around enough to get the
aircraft to be able to balance properly. There are only 2 pictures
available of the only flying kr I know of with tandem seating. There is
very little daetail on the modifications done to make it fly properly,
so I am kind of just winging it and theorizing right now.   Am I just
dreaming and making this more difficult than it should be? If I had the
finances I would be looking at something like the thunder mustang, but
of course I dont(as so few of us do). Perhaps I should be looking at
other designs?

I'm going to be at the Virginia Regional Festival of Flight once 
again as the photographer and webmaster.  Pictures of KRs are always 
posted on the web site.  All of the Va information is posted on the 
web and it should be a good event.

I just got back from the Lumberton North Carolina show where I serve 
as the photographer.  No KRs but it was a good show and a great weekend.

Scuse me, I went out and looked at the vent and it "IS" pointed forward. 



I don't know where I got the Idea it was pointed backward. 



I better look before I leap next time.

KR> RE: Fuel Venting on Canopy

[Bob Glidden]

Dan
That really should point toward the front in addition to venting it is also 
a way to put pressure into the tank to help move the fuel better. By 
pointing aft it is taking pressure out of the tank when you fly. Only takes 
one time for it to be an issue.

? O'l Blue (N4DD) has a header tank with a vent tube coming out of the top
just in front of the windscreen (not the cap) and is bent 90 degrees to the
rear and it seems to do just fine. It doesn't suck the fuel out.

While I was flying with Rick, when the header tank was re-filled by the wing
tank pumps it sprays out when the header tank gets full to let you know ? to
shut them off just in case you forgot about them. It hasn't hurt the canopy
any yet.

KR> Brochure of the KR-3 amphib

[LG McCaw]

Scott, 

If you read the little blurb above the picture, it says it's a
two seater, expected cruise is 115 knots.  Empty weight it 570 pounds,
full load is 1000 pounds. Power is 2100cc VW with a variable pitch 3
blade prop.  You might try writing RR and see if you get any
response.

Good luck,

LGM

KR> RE: Fuel Venting on Canopy

[Joe Beyer]

With a foreword facing vent you have a ram air effect which pressurizes the
tank slightly. With the tank being full the fuel gets to sloshing and when
it contacts the vent port, it unloads. I had that happen on a Aircoupe while
I was a passenger once. We were buzzing a barn at a friends place and gas
came out all over the wind screen. That main tank should be vented.

KR> Fuel Venting on Canopy

[John Martindale]

Geday Mitch

A low pressure area near the lower front canopy is often caused by the air
flowing over and around the upper part. Is it possible the vent lies in this
critical area and prop wash is causing the drop in pressure. Mark Langford
has some wool streamers photos that clearly illustrate a flow reversal in
this area. Don't fly until you have it sorted.

I am test flying a newly purchased Tri Q2.  On rollout fuel started venting

the header tank close to the canopy.  The header tank guage showed about an
inch from being full.  The main fuel tank cap is not vented.  There is a
