When will the build be over? I have a Monogram 1/109 scale F-101 Voodoo thats part done and would like to enter it.
As Bill has said, the current GB 14 build finishes on Sunday, 2nd September 2012. If you want to enter your part built Voodoo, this would normally be okay but can you give us some idea as to how far advanced it is built, some support photos would be good. Usually if it's not too far advanced it would be okay and this is usually agreed between the other GB entrants making comment on your request thread.
As to your other question, the remaining GB dates and subjects are listed here for your convenience.
GB.15. Wednesday, 1st Aug to Sunday, 2 Dec 2012 - Aircraft Carrier Planes
GB.16. Thursday, 1st Nov 2012 to Sunday, 3rd March 2013 - From WW1 to WW2 1914-39
GB.17. Friday 1st Feb to Sunday, 2nd Jun 2013 - The Jet Age 1944-45/Recon-Transport-Observer Aircraft of WW2 SPLIT BUILD

Sorry about this mate, but having just gone through all that spiel on your desire to enter the Voodoo, it's just dawned on me that the current build GB 14 Home Country Modern/Spitfire Marks (Split Build) is for current modern aircraft still in military service in your home country or for any type of Spitfire Mk.
So sadly, I don't think the Voodoo is going to fit into this current build. However, if you want and we would be delighted to see it, you can always post your F-101 Voodoo build in the 'Start to Finish Builds' category. I for one would be delighted to see it as I have a 1/48 F-101 Monogram kit sitting in my stash wafting for the right moment.
