Not posted in a while. There is a new game on STEAM that just dropped this week called FLYOUT.
You design and fly your own planes and helicopters. It's very difficult and there is a learning curve. The hardest part for me is learning how to design a piston engine. I don't understand fuel mixes and gear ratios so when I go to test it, there is very little power. My first 3 planes looked pretty, but could not fly. Yesterday I tried to make my WW2 Autogyro. After 2 hours of fiddling with the stats, it flew! I can hover, but the push prop is very weak. Only managed to go 75mph forward. The two engines are Allisons from a P-40. The bore diameter, stroke, and number of pistons is correct, but I had to guess on the gear radios to make it work. Lots and lots of guess work.
