The results are very disappointing, I know there was plenty of pressure in the vac bags...there seems to be some sort of lacquer mark in the finish I think this may be down to the release wax. Previously we have not heated the moulds, this looks like it has made a big difference to it's properties, me thinks a new release wax is needed. Also I have a question mark over the paint? It seems to have stayed a little soft in places, this could be due to the release wax?
The positive side is it came out the mould with very little effort and the dowel pegs for the captive nuts released very easily, it is well over engineered, this tailplane is as Strong as most wings, I think Mikes suggestion of only one shear web in front of the hinge line would be better also to use only 0.5mm balsa and only one outside layer of 25g glass cloth. This beast weighs a massive 125g a little on the heavy side, but if you need a ramp for under car inspection look no further....
Back to the thinking stage!

dude sorry to hear all did not go well.
I think you are right about the release and paint.
The paint you use out of rattle cans is solvent based cure not chemical cure like 2 pack. This may be the main problem, Might be worth a test with same release wax and 2 pack paint?
