More finetuning and cutting on the windscreen plexi. I'm getting pretty close now.
The sides are still a bit too much open so I need to do some final trimming to do towards the lower 30 degree position. There is a remaining small gap between the plexi and the fuselage skin on the sides and I'm not sure where to cut next or if it's worth cutting more.

As I was cutting back the sides, the windscreen also had the tendency to warp back making the fit with the slider plexi stand open.
I gently sanded away material from the bottom of the back of the windscreen and tried to keep a straight line as good as possible.

Some more pictures of the position so far. Not bad at all. Only those damned sides still stand out a bit. I think the remaining excess plexi in on the lower side towards the sharp bent in the top skin.

As I'm getting closer, I startd checking the height of windscreen versus slider. Here I'll have to add some nylon washers as shims to bring the windscreen equal or a slight bit higher than the slider for an easy fairing transition.

Same towards the other side. This is actually quite normal to do so I'm pretty sure as it's that subtile differnce in bow between the roll bar and the slider frame front bow.
I'm still on the right track.

Did some more fine tuning on the legs of the front bow to lower the slider a tiny bit.
This kind of things is actually very time consuming. you have to take the plexi of, do some filing and cleco it back on to check the fit and this in a repetitive process.
