Im not much for scripting yet but learning it as much as i can but till then, has or can anyone make a script to make a friendly dragon land and continue following after a battle ? First thing to get around would be them flying off into the sky after a fight and don't come back till you fast travel and then they are stuck flying in the ground next to you, if you tell them to wait they will fly up and land and then you can tell them to follow again but if someone could make a script to make them land and follow on their that would be amazing.

I would say this is rather complicated, might take a long while to have some of features you want working.
Few things to consider:
- Dragons don't just land or crash anywhere. They only land on 'Landing Markers' that developers put on the world. I have seen ppl use spell to spawn objects wherever the spell hits the ground. Maybe you can try to 'spawn' a 'Dragon Landing Marker' via spell script, then you can 'force' a dragon to land (via script). The dragon then will pick a closest landing zone.
- Dragons not really 'follow' you. In game, if you see a dragon hovers over your head, the dragon is actually playing a 'Scene' via non-mark Quest. You can try to create a quest with Dragon Alias that has the 'Scene' when you are not in combat. Check the Wiki for 'Scene' or 'Quest' for more details.

It is actually possible to make a dragon work like a follower. I've had it work with the exception of it landing after combat, though it isn't constantly flying but walking with you.

As to the OP, this is an issue I'm trying to work out as well. Everything but this works out, and it's kind of frustrating to have to fast travel after every battle. If I find a solution I'll let you know :3

You could use an Orbit package with the player as the target of the Orbit procedure. That will keep the dragon flying instead of following on the ground.
