My first ultra passion project: the sh-2 theres been about 20 hours of studying, working, and building this plane. all the numbers match the wikipedia paige, the fuel amount, weight, length, width, engine HP, all of it. I had to fiddle with a lot of the weights, drag, and fundimentals of each piece but it turned out well. it flies well but as it is a plane designed in the late 1920's and built in the 30's by someone in a shed it is a little quirky, at speeds over 100+ miles an hour it rapidly pitches up, which isn't a problem because it's top speed is around 88 miles and hour. It sways a little bit because the rudder was just not built big enough for this plane from the factory, and most glaringly taking off from water is a little bit of a process. you have to be going >60 miles an hour in the water and pitch up as little as possible for it to become airborne. if you want the history I'd highly recomend the wikipedia paige https://en.wikipedia.org/wiki/Shavrov_Sh-2 enjoy!
