[Sparetime]

Is the wing tank listed here the one for the xl?
if it is, are the any modifications required?

If you look thru the store items there is a wing tank and a pic showing it in a wing bay - the dimensions are given - the shape shown - on the (Legal Eagle) the wing diagonal needs to be dropped down and gusseted to the spar cap faces for clearance aft...

If you plan to enter the cab from the Left side then the tank should be in the right wing so the fuel line angling down does not encounter your head...

Any help/ideas on how to support and constrain the Mini Max Wing Tank.  I lowered the drag brace and it fits perfectly into the wing bay.

Go over to Photos in the yahoo group and look at the album titled "LE TX Bob Severance" with 79 pics in it - the detail is there...

Thanks Steve.

Thanks Steve.

I put Bob's photos on the yahoo group Pinboard...

Thanks Steve.

I put Bob's photos on the yahoo group Pinboard...

The Pinboard has disappeared from the yahoo group and working admin controls of same - per usual dead silence from yahoo wiz kids - hope they bring it back as it was a good tool - the yahoo group searches and file handing procedures change or act differently almost daily - it's nearly Facebook...

I did get a good look at the pinboard before it went down.  Thanks Steve.

I was wondering how come all those pictures got pinned... I still see them all!

[CHARLES DEBOER]

Bob, Steve was trying to help me with my question on how to best install a tank which I purchased that was originally for a Mini Max wing.

[Bob S.]

That's good Charles. I hope you see that I doubled the diagonal where it was under the tank and put another support outboard from two 1/4 x 3/4 epoxied together to make a T. I put thick felt on all contact points so the wood did not touch the tank anywhere. The fuel pickup is in the rear corner. I have to be careful to never run the tank less than about 1/4 or risk exposing the pickup tube. especially in any nose down attitudes (landing?) There is no way to put a sump in the tank. Since I am running a pump, my fuel line is NOT as it should be for gravity feed...although with any siphon it draws ok...
If you have any questions, you can IM/email me directly if you want...

Steve, If I drop the wing diagonal down I won't be able to bolt it to the wing attach fitting on page # 36 also described on page #38 detail.  Is there any special reinforcement needed for that diagonal other  than what is described on page # 37B after dropping it down to the bottom spar cap?  Should I leave out the steel fitting described on page #38?  I don't want to drill through the spar cap.

Charles:
The metal fitting on sheet 38 will not be used if you drop the diagonal down into the face of the bottom spar cap strips... The diagonal will need  1/8" plywood gussets top and bottom sized to handle the load of the tank and the racking forces in the root wing bay...

How do you keep material from falling into the MimiMax tank while drilling the hole for the fuel line fitting?

Second question: has anyone weighed their fiberglass fuel tank?  I know I am adding weight with the mimimax tank at 6.6 pounds.  Just wanted to find out how much.  Been doing really well so far.  Haven't deviated from the XL plans except for a .020 thick turtle deck over the foot well between station #1 and #2.

Had to expand the wing bay by one inch.  It fits perfectly but tank will expand once filled.  needed extra room for expansion.  I removed the rib portion between the front and rear spar and install another rib one inch further outboard from the original rib by using one of the extras I made during the rib build process.  Replaced the cut out portion rib with another extra rib and covered them both with .8 ply top and bottom just like the #1 & 2 ribs inboard at the wing attach fittings and used .8 ply webbing on the intercostals of the rib for more strength. (for side loads in those tight turns ...)  Made a tray out of 1/16 th inch ply and drilled lightening holes, added  two extra drag braces.  See pictures below.
