Hi,

Got my vacuum bagging kit and almost ready to start experiment of making moulds and parts to radio controlled planes. 

I do intend to make a mould like your air scoop in your videos. 
But I am not sure how to the part itself from epoxy, fiberglass and carbon. 

May I put on release agent 
Paint the mould 
Layer of epoxy brushed on
Put fiberglass and carbon in place with hands as good as possible and then put it into a bagging setup?

Not always easy to tell from pictures. Is there are return lip on the bottom that's required on the finished part. If so I'm seeing a 5 piece mould. Top, bottom and 3 segments for the sides. The two undercuts (closest to the top and bottom) seem like natural split lines for the top and bottom pieces of the mould. Not a straight forward part to mould or produce, if your new to this I would be giving this one some careful thought.Doze Although you say the center area of the top is not needed I would still incorporate this into the mould/ part and trim it afterwards.

Good luck Warren
