What are the best Youtube tutorial series to watch to progress in KSP please?

[besp09]

Really enjoyed getting through  the very basic missions (in career mode) using Mike Abens videos to guide me - they are great, but don't cover everything as I appreciate KSP is huge in terms of functionality/build options.

Are there any other youtubers worth watching - as I am now struggling to work out how to apply the new tech I am unlocking in the R&D tree. 

Thanks.

One well-regarded series is this one.  It uses older versions of KSP so the user interface will be slightly different to what you have, but the ideas are all the same. 

One change with newer versions, experiment storage containers, gives you another option for carrying 'science results' back home, so you might look at that on the wiki and decide if you want to use it as you follow the tutorials made before it was in the game.

Yeah I agree. I still think Scott Manleys tutorials are the best out there.
