DRIFT PROBLEM WITH AIRSHIP SCRIPT

As the title states I have a weird drift problem with my airship vehicle. The vehicle functions with linear and angular velocities placed on the vehicle seat (see image) and parented to my control script (see code)

Control Script Code:

local seat = script.Parent.VehicleSeat

local fuelValue = script.Parent.Fuel
local steerAngle = 30
local speed = 60

seat.Changed:Connect(function()
    if seat.Steer == 0 then
        script.AngularVelocity.AngularVelocity = Vector3.new(0, -1 * seat.Steer, 0)
        script.LinearVelocity.LineVelocity = 50 * seat.Throttle
    end
    if seat.Throttle == 0 then
        script.LinearVelocity.LineVelocity = 50 * seat.Throttle
        script.AngularVelocity.AngularVelocity = Vector3.new(0, -1 * seat.Steer, 0)    
    end
end)

Any help would be appreciated. I can also share the settings of the linear and angular velocities.
