Yes !! First Atomic Wedgee out of the mould


Finally I have popped the first wedgee out and i'm fairly happy with it all.
I had a few problems with water in the airlines when I sprayed the paint but it look OK on the outside.
The carbon spar caps and reinforcements show thru the yellow paint but I can live with that.
Just glad it all released from the mould really well.

It should weigh around 850 - 900 grams (30 - 32oz) and have a wing loading around 16 - 18 oz/ft2.

Oops got the weight wrong, I wish I could read my scales properly!!

It actually weighs just under 600 grams (21oz) and has a wing loading around 11.4oz/ft2 and about 17oz/ft2 ballasted.


I still have to mould the new larger fin and cut the elevons out, but it's getting real close to flying now.

Great work, the plane looks very nice! It appears your plug is made of wood then glassed? How/what did you then make the mould?

Hi Don,

The plug is abs plastic from a 3D printer then finished with automotive paint.

The mould is epoxy gelcoat backed up with glass & epoxy and filled with non shrinking grout. Very heavy!

Lots of work but worth the effort.

Very nice work Shane.

What release did you use in the mold - I see you were able to mask the paint in the mold.

Like the Yellow and Blue - all my planes seem to be yellow and blue

cheers jeff

Hi Jeff
I used mould sealer and 8 coats of wax from fgi.
I don't want to use any pva.
It popped out of the mould realy easy.
The yelow and blue is easy to see in the air and it is what I had.

Cheers shane
