Gun Turret Firing the wrong direction

Help and Feedback Scripting Support

Hello.
Working on a gun turret for my japanese dive bomber.
It works, but it fires the wrong direction which is rather annoying
Code:

wait(7.1)
local plane = script.Parent.Parent
if plane.Parent == workspace.RedPlanes then
	targets = workspace.BluePlanes
	bull = game:GetService("ReplicatedStorage").Ammo.JB
end
if plane.Parent == workspace.BluePlanes then
	targets = workspace.BluePlanes
	bull = game:GetService("ReplicatedStorage").Ammo.AB
end


local function FireGuns(angle)
	for i,v in pairs(script.Parent:GetChildren()) do
		if v:IsA("BasePart") then
			local bullet = bull:Clone()
			bullet.Orientation = angle * -1
			bullet.Position = v.Position
			bullet.Parent = workspace
			wait(0.4)
		end
	end
end

local function findNearestEnemy()
	local MaxDistance = 99999
	local nearestEnemy = nil
	for i, enemy in pairs(targets:GetChildren()) do
		if enemy then
			local distance = (plane.PrimaryPart.Position - enemy.PrimaryPart.Position).magnitude
			if distance < MaxDistance and enemy.Health.Value > 0 and distance < 1500 then
				nearestEnemy = enemy
				MaxDistance = distance
			end
		end
	end
	return nearestEnemy
end

local function FindAngle(nearestEnemy)
	local origincframe = plane.Engine.BodyGyro.cframe
	local dir = (plane.PrimaryPart.Position - nearestEnemy.PrimaryPart.Position).unit
	local spawnPos = plane.PrimaryPart.Position
	local pos = spawnPos + dir 	
	local angle = pos+dir
	return angle
end

while wait() do
	local nearestEnemy = findNearestEnemy()
	if nearestEnemy then
		local angle = FindAngle(nearestEnemy)
		FireGuns(angle)
	end
end

All help is appreciated.
Thanks!
