Still flying mine. Probably my favorite jet. I don't remember my exact flap settings, but seems like I have the landing flaps set for more extension than 40mm. With gear and landing flaps down, it gets real draggy so stay in the throttle.
As to low and slow, remember it is a Hawk and will snap with the wrong combination of speed and elevator. I enjoy the low passes. But mine are all at a safe speed.
You will enjoy this plane.
