Simpleplanes is an amazing game. Im just gonna start out by saying that. Now, with that said, I have a few suggestions on how to make it EVEN better.
First, add more weapons!!! Humans like things that go boom!!! I may be the only one who does this, but whenever I download a plane, 99% of the time I don't land on the runway, but into the side of the mountain. So I think it would be cool to add new bombs like a nuke. I understand though that maybe a nuke would lag out the game too much, but for faster devices, that would be a cool feature. Also new missiles would be nice, along with maybe a larger size of rocket pod. And laser guns, cuz why not.
Another thing we would all like to see is more structural parts! Like doors maybe, for passenger planes, that would be cool. Also a way to fold the wings without putting a rotator inside of a fuselage.
New types of landing gear would also be pretty swag. Like one that just has one wheel, or something that stretches out forward and to the side. Or just a bay that folds out and make customizable wheels, and parts that connect the wheels to the plane, etc.
It would also be cool to make just more customizable parts in general, like cockpits and engines. I say this because it is very hard to put a cockpit inside of a fuselage for me. If we could choose the color of different parts of different parts, like you want the color of the glass part of the cockpit to be yellow, and the frame to be black, but the rest of the plane is grey, i'd like that.
Also just a little bug fix: the plane wants to run off the side of the runway at yeager airport. ( I don't know if its just yeager or all of them, I mainly take off at yeager.)

Those were my suggestions as to make this game more fantabulous then it already is, i'm sorry if I have offended you by posting an annoying thread. But please comment below of what your suggestions are! Thx :)
