Stahlhart has a collection of aircraft that are astounding! These are just some of them. Then each model has many liveries. These are real models, not the simplistic (but nice) models offered by Ojimak. More satisfaction from the realism, and they are all FREE! Check out the Chinese Architecture, the Beijing Drum Tower, it is magnificent.

There are 25, I believe, liveries of the Sturmovik alone!
