this is a little test that will help some people if thay want to make something like air refueling or close call shots

it's concept is super simple

basically it's an air brake that its input set to IAS>111 111m/s is 400km/h

so when when the plane goes 400km/h the air brake will activate, making the plane go under 400 (probably 397-399)

and the loop continues, the air brake makes the plane slower when it hits the selected speed, the engine will try to over that speed but the air brake won't let it

if you want your plane be more accurate i recommend using a vtol engine and set the activition group to IAS<111

so when the plane goes 400km/h the engine will turn off

i used the vtol engine cuz it doesn't have a rev up time when it turns off it turns off immediately

using a gyro for maximum stability is also recommended

That's it

if anyone who's good at funky tree can you try to like.. Make a code that can make the plane stay still at 400km/h and make it DEAD CENTER, it'll be very useful for me :)

edit: nvm i tried this plane now and it's pretty accurate it only does 399-400 km/h which is great lmao
