> "Also, probably due to my awful flying

on takeoff the plane seems to jump when it leaves the runway. Anyone else notice this?"
In that case, my flying must be awful too.

Although since the effect is also seen when using Hardy's automagic take-off, I have to conclude that the problem lies elsewhere.
As seen from an outside view, the aircraft appears to stick to the runway and then leap abruptly skywards. (Also, during rotation the tail of the aircraft not only impacts the runway but actually sinks beneath it for a time).
This unpleasant-looking combination means that when making a video, heavy editing is required to try and mask these effects....

Happily, their duration is relatively short, but they do occur at a rather critical time.
