I am buiding a hardtop for a super 7 by making a model of mdf  and airplane triplex.

What would be my specific needs to make a carbon hardtop copy of that ?

In simple terms you will need to take a mould then use the mould to make the part.

I recommend you watch our video series on making a bonnet.  It goes from the original panel to the finished carbon part over 3 videos and shows the panel making process.  It can be found here:

If it's a one off then you could use a lost mould method, use a foam former that will dissolve in acetone, make the former a little smaller than the finished piece to allow for the layup. Mould the part then disolve the foam. It will require a bit more finishing than if you were using a proper mould but it's a cheaper way of doing a one off.

Thanks for your quick reply , I ve seen al the video tutorials  ,great stuff , but I get a bit confused by

  the shopping list next , it seems to me that some things are  mentioned separately and then as a starter pack

  Could you please explain how I should read it ?

yes they  are deliberately like that.  Some people will have had a starter kit before, so already have pump etc, or others may have bits from previous projects, so we list both so you can choose.
