Models All models are to scale! Click on any picture to make it larger.
To help me understand what the plans where on about I decided to make some exact 3D digital models of the viper by following the plans
The models clearly show how the basic cockpit is constructed.
   

I have now produced some 3D models to show how the drive components will link up to the engine and fan.

  These 3D models are extreemly usefull to help figure out how to solve problems witout wasting expensive material. I will be producing more models as the build goes on.
