In the meantine, with the 2012 Afrika project looming closer, roughly 10 months to go, I received my flightstands from Armaments in Miniature. http://www.angelfire.com/nj4/armamentsinminiature/aircraftinmotion/checkyour6flightstands.htm They arrived in double quick time from the USA to the Netherlands, 4 days including the weekend. This was a collective purchase with fellow local gamers and we picked the thinnest base but with the maneuver stand. Dave, the owner mentioned that this stand was a bit thicker and would not fit in the base, but with a bit of trimming it would not be a problem. Some sanding and hot water later and the stands slipped in like they were meant for it.
(yes, it is a bit off to the right)
It comes with cast in holders for 3 dice, I sanded those down and put down 5 layers of roofing lead sheet, glued those in place and put a thin layer of Milliput over them for added strength. When it was all dry, I sanded down the sides where needed and coated it an a layer of sand. Standard brown topcoat with Dheneb stone drybrush, with plenty of flock and tufts later gets me this:
So now I have 5 flightbases suitable for Europe and various other warzones, and 5 should even be enough to game in Vietnam (provided I'm not the only one with flightstands). With these I can mount all of the helicopters planned for Zwartwater.
I know my bases aren't as thin as Rutgers, who used 3 layers of lead and with a much nicer slope, but I'm scared to death one of my Loaches comes crashing down. Each base weights in at around 350 grams deadweight so I should be ok.
