I framed up an 18" x 48" piece of 3/4 " ply on 1"x2" oak, nice and straight. When in use , i place it on an old bar stool, when not in use , it just stands up in a corner , out of the way .I also made a removeable bolt on 24" extension for the bigger sections. I cover it with a piece of ceiling tile and cut off the extra width , a couple of small dabs of construction adhesive holds it in place , just be sure to press the ceiling tile down firmly.
I have built no less than a dozen projects on the current board , no problems with pinning spars, ribs or whatever to it .
If you need to replace the surface , just pop off the used ceiling tile , remove any adhesive that has remained on the ply and start over . Cheap and easy.

I get Homasote at Menards. Check out www.homasote.com for a list of suppliers. It is still the best material to build models on when using pins. Ceiling tiles are to soft to hold things form. Drywall is to hard. Cork is not bad but Homasote is cheap and has the right characteristics. I build on a piece that I have had for about 7 years. If I get a glue spot it can be sanded flat. It is just a compressed cellulose material. My father used it for exterior siding on a shed in the back yard. I painted it and some 40 years later it is still in great shape.

I bought a 4x8 homosote sheet at Menard's about 7 months ago. They had it in the store.

I still like my drywall for building on. I've never had any problems getting pins into it and they hold very well. If it starts getting too many pinholes in it, a little spackle, a light sanding and it's good as new. I just paint the ends to prevent moisture from seeping in to the board, but other than that I don't do anything else to it.

I've used drop ceiling tiles, homasote, sugar pine and several other types of materials to build on through the years and I always go back to the drywall. It should also be noted that I rarely if ever use CA glues and if any wood glue gets onto the drywall, it sands off without any damage to the drywall. (Try that with CA glues! )

A layer or two of foam core board attached to a flat surface works very nicely, but is not especially cheap.

I am still using 1/4" cork tiles over 3/4" MDF framed with 1"x2"s or so.
Someday I may invest in magnetic building board systems.

I prefer jelutong or sugar pine planks, but these are getting to be hard to find. The Great Planes board is very nice. See: http://www3.towerhobbies.com/cgi-bin...?&I=LXPF36&P=7

There is also a discussion ongoing here: http://www.rcgroups.com/forums/showthread.php?t=1582494

If you opt for the ceiling tile approach, you may want to brush on 2 coats of any left over color wall paint , flat , satin , it doesn't matter which. It firms up the surface.

The paint won't soak in and warp the tile? Never heard of this idea, but I'm open minded and interested....

Ditto, that's what I use. Cheap, flat enough for my woodies, holds pins great, and just throw away and replace when they get ratty.
