I should have just let this go, but it is not a valid comment. The 1g
experienced by an airplane sitting in a hangar is simply not a load case of
any significance, and has no bearing on anything in this discussion.

I respectfully disagree. When sitting on the ground, the "1g" weight of
the fuel is supported by the landing gear and everything else when the
tanks are located in the stub wings. When the fuel is located in the
outer wings, the weight, multiplied by the arm of the fuels cg, is
supported as torque
So what do finished wings way? 40 pounds? I just don't see how anyone
could be worried about the wafs holding up to lets say 100 pounds with a
full tank on one side while it holds up to 400 or even 500 at times from
the other direction ( and this is half as the wing on the other side
carries ha

Why the continued discussion? The plane was designed with retract gear and
wing tanks, at least in the January 1990 manual. Nowhere have I seen stub
tanks in the manuals that I have access to.

As I stated in the begining, wing tanks are great because they don't figure
in the gross weight of a flying airplane, the weight only becomes a issue
during landing and on the ground. AS stated in the begining s
I have not posted a reply to the KR network in a long while, but I think
that it is time to break my silence. I have wing tanks it the outer panels
of my project. I have not measured the capacity yet but they are on the
order of 20+ gallons . . . each. That goes along with the 4+ gallon heade

How To Determine - Cylindrical Tank Volume
Using the diameter of the tank, multiply the diameter by the diameter (D x
D), and then multiply by .7854. This will equal the square area of a
circle.

In the January 1990 of the KR2 manual, not KR2S, Page 82 talks directly the
installation / methods of a wing (not stub) tank addition resulting in 6
gallon tanks (and how to make them bigger). There is no mention of impact
on G loading.

I read some of the concerns about added fuel. Someone stated(last week I
think) added fuel adds to the time in the cockpit. (small cockpit). I have
been looking at options about added fuel. I have a dated KR with retracts.
No room in the stub wing for added tanks. I have been looking at option
a 6" tube x 8" long is 1 gal ( 231 sq. in /gal ), I don't think you could fit
much in there , aft of spar may work better
