Yes it is worth getting it, but imho only to support the Devs to improve lots of things.
For your personal interest, you could be dissapointed getting it at this moment as many things don't work ( for me that is)
But The Tangmere Pilots are a very patient Wing, we waited years for this, so we can wait some more
20 of our Chaps have it and we flew together some 1400 hours (i counted it on Steam) to test things
So far we stopped testing and waiting for the next patch
Just buy it and support the team, but be patient for the results
good luck
