So at klax I took off and then

What happened my plane took off but crashed was there a bug?

You took off withour flaps, that’s the main issue. They’re needed to generate extra lift at slow speeds, both for takeoff and landing.

But every time I take off it is smooth

With no flaps

Flaps are needed for T/O for lift. It’s used on almost all T/O procedures for any aircraft in pretty sure.

Ohoooooo

Thank you for the help

Ehhh, technically, not really. They’re helpful, but with enough runway, anything can depart.

My guess is that the OP called VR too early with flaps up and maybe even was operating a longer flight, and the sudden rotation caused a stall.

You had no flaps and 0 trim

You can still takeoff with no flaps and trim, I’ve done it many times without problem

True I did to

How fast were you at rotation @Passengerjet999?

At a neer tailscrape point

So you were not going very fast on rotation

Yep true indeed

Well that’s probably why you stalled lol. You got to be at a fast enough speed in order to rotate and not stall

I pulled up and went full speed at stall

Yeah you could T/O without any flaps or trim only if you accelerate powerfully and use the brakes as a sort of slingshot when you generate enough thrust. It’s not realistic but it’s the freedom of IF so who cares. For T/O use flaps but not full flaps and full power as it’s not realistic. Use a slightly lowered flap setting and just enough N1%. I’d say around 86-94% depending on weight. To be extra realistic you can calculate a reduced takeoff thrust setting but I’m not sure if it’ll work on IF.

If this was real it would look like this!

edit:

More lift comes from more speed, more AoA, and/or more flaps. The less you have of one, the more you need of another.

Trim doesn’t affect lift. (it assists with holding pitch)

I disagree, sturmovik’s statement:

is correct.
While at the same time your

is also not wrong, assuming an aircraft is not specifically prohibited from using no flaps.

As for

Yeah, look at the op’s first image, it looks as though the rear of the aircraft is below the wheels while barely off the runway. Tail strike for the high AoA needed at the low VR?
Subsequently mentioned:

Me too. Trim of course doesn’t affect lift, though can affect the feel of the rotation.
