I dont fit!

[Flyguyeddy]

I need to make a new seat so i have been trying to guestimate how long it needs to be.   This is me sitting on some plywood planks positioned to be pretty low in the back.  I am 5’9” tall and my head is firmly in the rear tubing cluster.  Doesnt seem like a fun place to be whilst flying without a helmet.   

What am i doing wrong here?

That is the XL right?  Man you are scaring me - I am 6'1" and if you do not fight at 5'9", I am going to have some real issues with mine.  I do know the standard aluminum mesh seat does sag down a bit but not sure how much.  Not many side view pictures out there that I know of with bigger pilots in the XL - anyone?

Well I can say at 6' 3'' I did make a longer seat,  moved the top tube up 2 to 3 inches and extended the wing mounting bracket to make the bottom of the wing flush with the top tube.

You said you moved the top tube up 2-3" and I think we can visulize what this entailed easy enough.

What do you mean by  "extending wing mounting brackets"  Are you making this change to the wings or to the frame above the extended top tube?  Got photos?   
By these things happening, your struts became longer yes? Or did you keep the same angle and move the strut ending location? (this would still make the struts longer)

Looks like perfect fit to me, its not the chair you sit in to watch the game, maybe lots of foam pipe insulation? however i am 5' 9" also and building the standard eagle, now time to study seat mods.

I believe extending the wing was referring to moving the wing mount attachment bracket.  In this case moving them down on the spar which would move the wing up.  I have seen this discussed and I believe approved by the "boss".

While this is probably true, (but who knows) it would seem that a simple explanation done by the person that said they did it, would suffice in this case.  One of the biggest problems I see in small aircraft building, is that "a proven way that works"  gets interpreted into many variations with SOME of them not working... wasting time for many, and certainly could cause set backs.

We all know that just in cosmetic finish alone we could have 10 identical XL's sitting in a line with huge difference in looks (which is great) but fundamentally in structure they are all done in a correct manner.   

Simple statements such as " I thought I could leave out a station, or spread the ribs or use lighter tubing here"  leaves far to much to the imagination. For the average builder. in my honest opinion.

I made the change to the frame above the extended top tube.  I have a pic but cannot get it to load on the website.  Yes, the struts did become longer.  Same angle with longer struts.

I found this with a search. I would try it.

 Your final see could look something like this .

No body has said what's wrong with the plans seat    Leonard

That doesnt fit either

Just an observation... My LEXL plans show the short vertical tube between station 2 and 3 to be between 7 and 7-1/2 inches behind station 2. It may be the angle in your photo, but it appears your vertical is farther back, which shortens the area between station 3 and the front seat mounting tube. Wouldn't moving the front seat mounting tube forward give more room for seat sag and allow you to sit lower?

[Flyguyeddy]

That is a possibility.  If im not mistaken, this may have been a previous builder modification (he was a little bit shorter than me)

Could you take a measurement or two and report back, my frame work and yours sure don't look the same (thus fit the person, a lot differently) 

Most notable difference  would be your  front over head tube cluster to overhead rear cluster c to C measurement.  
I would be interested to know this, and why yours seems to be canted fwd at the top a great deal more.
