Snowspeeder cockpit hinge problem

[Hazardous]

Hi all,

First post on this amazing forum.

I have a Snowspeeder problem that I would appreciated your help with.

What is the best way of designing the canopy hinge in CAD so that the canopy can open without rubbing?
I plan to have it powered by a servo, attached is a video showing the problem and one of my reels showing my WIP.
I have built this model from scratch in Solidworks.

I assume I will have to make the mechanism slide forward first the rotate up but I know someone on here must have tackled this already.

Any help would be much appreciated, Jason

Hello and welcome to the RPF!

To me it looks like the axis of the hinge is a tad off. I think it is best if it is as close as possible to where the canopy joins the roof.
With your "extension arm" the hinge can be placed more to the inside but it has to follow the "middle line".
"a" and "b" have to be the same angles. Hope this makes sense.

And all the best with your project!

Thanks for the reply Protoss and for the welcome.
I will give that a go and see how it goes. I'm trying to keep the pivot points etc as close to the movie model as possible but at the same time I need it to work

Will post an update when it's done. a/b helps a lot too.
