Hi, This is my first time trying to get vehicles to work with bodymovers.
Right now my helicopter can go up and down with Q and E, it can move forward with W and backwards with S and it can turn with A and D.
My problem now is that the helicopter isnt going forward relativly to its lookvector I believe.
This is my Explorer View

local ContextActionService = game:GetService("ContextActionService")
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()

local ang = plane.Main.BodyAngularVelocity
local zeroVector3 = Vector3.new()
local RunService = game:GetService("RunService")

function MoveUp(action_name, action_state)
if action_state == Enum.UserInputState.Begin then
y = -10
end
if action_state == Enum.UserInputState.End then
y = 0
end
end
function MoveDown(action_name, action_state)
if action_state == Enum.UserInputState.Begin then
y = 10
end
if action_state == Enum.UserInputState.End then
y = 0
end
end
function MoveForward(action_name, action_state)
if action_state == Enum.UserInputState.Begin then

end
if action_state == Enum.UserInputState.End then

end
end

end

end)

ContextActionService:BindAction("Down", MoveDown, false, "e")
ContextActionService:BindAction("Forward", MoveForward, false, "w")

With a quick glance I think something along the line of vel.Velocity = lookVector * velocity would work. Where lookVector could be the LookVector of some main part in the Helicopter such as the Main part.
Sorry for the late response, I had some trouble getting your code to work with a simplified version of your plane. (and annoying issue of my internet persistently shutting.)
After trying like 10 things (and them not working) I decided that maybe we are going about this entirely wrong. Instead of using a BodyVelocity I suggest you use a BodyThrust
local velocity = Vector3.new(0, y, -x) * 50 --// 50 is just arbitrary debugging value that I added; you can remove it.
vel.Force = velocity
ang.AngularVelocity = Vector3.new(f, z, 0)
I appear to for some reason had to put the fowards / backwards thrust in the z coordinate and to have to flip the sign of the value.
(You may have to use Vector3.new(0, y, x) instead or Vector3.new(x, y, 0); I assume this issue is just because of how I built my plane.)
Here is a choppy clip of me driving my simplified plane with the code:
I am getting the LookVector of a part from my plane and adding the movement to it aswell as some speed variable.
What works? : it moves forward towards where it’s facing BUT it’s still not really working because it looks like it drives against an invisible wall. I can only go forward in 1 axis.
Likely because when the LookVector approaches 0, 0, 0 the result of the LookVector * otherVector will produce a Vector3 near 0, 0, 0. I don’t have any idea how to solve this problem but I have a solution that just ignores the problem and uses a different method.
You could default back to using a BodyThrust for moving forwards and backwards, and then use a BodyPosition or a BodyVelocity for moving up and down.
Alternatively instead of using a BodyVelocity or BodyThrust you can use a BodyPosition for thrusting where you would simply just set the Position property to LookVector * Force
How did you managed to get it work with BodyThrust?
I can’t get it to move forward, Turning it works fine but it’s not working moving forward even after trying some stuff out.

There are only 4 directions on a 2 dimensional plane and that is the type of terrain you are navigating when you want to go “forwards / backwards / left / right.”
I want the helicopter to always move forward even if im 45 degree turned. Right now it only moves forward when its 90 degree turned.
Edit: Its not like in your clip you’ve send.
