Piper PA-18A Project

Hello, i am on the road of restoration of my new 1956 PA-18A, it was used for Ag for about 20 years and before just like a normal airplane, it will need a lot of work to do, but after 10 years of not being flying we could start it up and fly it 500 miles to his new home in Argentina.
I will upload some pictures and hope to get some help from you folks.
It flies super nice, never had a crash so the shape of the airplane is very good.

In agricultural operations, the most important instrument is the spray pressure gauge. The pilot might glance at the oil pressure / temperature gauge during procedure turns and the tachometer during the takeoff. The remaining instruments are surperfluous.

You are right, the last time when it was still spraying it did not have the air speed indicator working (bend tube) or the tachometer (broken cable). but it flew with 90 gallons..
 
The PA-18A is one of the few airplanes that will fly with a payload equal to it's basic operating weight. It doesn't fly very well at that weight and you need to be very gentle with it, but it will fly.

Of course the airplane flies much better as the load gets lighter while you're working it.
 
Of course mine wasn’t in as good as shape as this one, but it’s getting better. I also still have the tank

Our family can attest to that! I can still hear My uncle kindly asking us to make sure we shovel the urea more to the front of the hopper so he didn’t have to lock his elbow just to keep the nose down. It would fly very heavy.

Amazing how much room the original internal hopper takes up. You can’t bring you arms back beside the seat, becasue the hopper takes up every inch of space behind.

That was the downside of the PA-18A as a cropduster: crashworthiness. The load was behind you, the fuel lines inside the cockpit, the engine just over your toes, and 18 gallons fuel tanks on either side of your head. That's why the majority of accidents in PA-18As were fatel while that is not the case in Stearmans or purpose built ag airplanes.

Added to that no "both" position for the fuel selector so it was quite easy to run a tank dry at exactly the wrong time. That one item alone killed a lot of ag pilots.

Brother from another mother! is pretty much the same panel, do you know if beside the cross bar that goes in the top of the rear set there is mandatory to have the rear seat installed?? I have a lot of work to do in the airplane and that's a good thing :)
Your wings look really nice!
As far as I know the cross bar is mandatory in some form. I have replaced mine with the removable one with stc (see picture below) but there is far far better knowledge from others on this site. I just grew up with a A model, I’m definitely not a mechanic, just an ATP and a farmer. I am looking forward to your progress.Please keep us informed and keep showing off that wonderful find!
