| Subject: | Long range fuel for the "9" |
Hi Carlos,
I do not know the size of the holes in the "7" wing but my
"metals" catalog which shows me all the types and sizes available shows
an aluminum tube in 6061-T6. This is the only "drawn seamless tubing
large enough to be used for an extended range tank in our wings the way
Safe-Air does them. Industry standards have available 3", 3-1/2", and
4" O.D. tubing. I don't remember the hole size in the wings, but there
was no room to slide the tube into the wing. If you look at the pix of
the "7" wing tubes, they are supported with tabs that attach to the ribs.
There is no room for the "9" wings to slide the tube into and to utilize
the tab mounting. The tube is just a bit to large. You could go into
the wing, if you are building the wings, and enlarge the hole to accept
the standard tube size. Again, not an easy task. I bought quick built
wings and I figured that the effort was not worth the additional work.
The interior tank was a much more acceptable method of getting additional
fuel. Plus, I could remove the tank if I did not need it. As I said, I
decided that the additional fuel was not in my cards. My travels run
about 550 NM. Just enough distance to require one refueling. Of
course, that is in a NW direction which is against the prevailing winds
so my cruising distance with a minimum of 30 to 45 min. comes up short
with the standard tanks. Oh well, a break for potty and fuel is ok.
