Problem with prop texture

[HLP DESIGNS]

i have modelled a simple single engined prop to teach myself to map textures for another project some might have seen it in my last topic anyway all the textures work except the prop texture it shows the bitmap in fsx but it is not transparent u look at model from front and u can see landing gear strut and canopy through prop but nothing else the texture is 256x256 in 32 bit format any ideas :S

You speak a language (with respect to modeling) with which I am unfamiliar...
