There was a bug with the incorrect positioning of the light points (taxi, takeoff and landing lights) which are incorrectly positioned on the DH8D aircraft.
As you can see, they are strange, I believe they can fix it in the next update
With the same aircraft, a bug is in the spoilers that remain active while it taxis to the runway, but when it takes off, the spoilers deactivate, strange…
It might be a real light on the Q400 but it doesn’t look right catching on the model so I’d still say it was a bug. Noticed it myself with Qantas Link’s.
