Default SPAD Hell On Rails Yardstick Spar?

Hi guys. I may have posted this in the wrong forum earlier.
I am building this plane and was wondering if the yarsdsticks I got from Lowes are to tall at 1-3/8 inches.
I can't seem to find any details except to use a cheap yardstick from Lowes/Home depot etc. Please advise if this is not to tall for the spar or any other hints you combatters may have.

Thanks

I just scaled one up from the directions here. http://www.spadtothebone.org/PDF/Buhor.pdf it looks like just over one inch, not 1 3/8". I just used some spacers that were separating 2x4"s at the lumberyard. They were free, I had to sort through for straight and unbroken ones, and ones that were tapered etc. I actually made the wing thicker for an Extra wing. It was 2mm coro though, and it bends nicer. Some of the .15 size wings are run through a table saw to make them thinner, like 7/8ths"

Thanks Aspeed.
The yardsticks in the pictures look exactly like the ones I have. So it must be ok. It just looked like they were to tall.
I wasn't sure if a fatter wing would slow me down too much since this is my first SPAD build.

I've bought some of the those yardsticks from Lowes and they are too tall compared to the good old days "cheap" yardstick. Yeah you can strip it down, they also seem a bit thick. I Googled "cheap yardstick and found these 36" Yardsticks Back in the day, now I'm showing my age 64, stores would hand them out free with their name and logo on them. Now we have to buy them. Like aspeed recommended, if you have access to a table saw you can strip a few out easily to any dimension you need. There is a "SPAD Psyche" you should try to adhere to. It should be easy, cost next to nothing, not bought from a hobby shop, feel free to experiment, and should always be fun. Adhere to as much of that and you will have a fine SPAD.

Yep, be a cheap bugger and experiment. Thin it down as much as you dare, just fly safely. If it breaks, well, that was fun, wasn't it? It is almost like a reset button when a SPAD crashes. Well, my receivers seem to break, but the plane is expendable.

Thanks Tom and Aspeed. I've been flying for many years but never really bashed any kits. I figure experimenting with spads is not to costly venture. I too remember the old days of free yardsticks. And I'm only 57....
