I thought you might want to see more Richard so here you go.
i'd marked out the outside of the parts with a fine marker and roughly cut them all out, the last time i did this i slipped with the knife and ended up in hospital

marked out

then cut out !
Alot of people out there know how to build vac form models but there are alot who have never even attempted one, so these few shots are to show you how to strengthen the wings and sanding the proper way etc
I might have to leave this for a few days as i will be making a vac' form valiant for someone who had a go and couldn't make it, so i'll be seeing if i can reclaim it back to life

Many people do fancy ribbing, but i find the best way is to put strips of styrene 1mm to 2mm in thickness along the length of the wings, This also keeps the wings nice and flat when you start rubbing them down. To hold the wings nice and true wood dowl will be placed through the wings into the fuselage then into the other side of the wings.
Gluing these strips in also stops the wings from bowing out when you
press down to sand them.

The strengthening strips are put on before you do any sanding, if you don't when you come to sand the part it will flex and you will get uneven sanding, this is when everything goes all bannana shapes

For small parts its best to hold it with a good lump of 'blu tac', This stops it from slipping out of your hand, also sand in even directions taking care to look at the part you are sanding, the idea with the black marker pen outline is that you can start to see it appear on the sanded side and your getting ready to stop sanding.
When you sand the parts down you want to evenly press all over and to know if your doing it right the entire marked strip should all come off in one go, well usually in one go !
Don't go mad when your sanding it, take your time and keep looking its far better to undersand than to oversand and don't press hard .

The finished tailplanes and stablelizers, not glued together yet but they fit very squarely.
