Yeah, this was more or less a joke teaser. You can check out the thread that Eric pointed to, it has the actual design. This was a testing stand to see what kind of thrusts we could get out of various setups. We have a standard 6WD drivetrain and the fan is for extra push.

We actually found that the 1:2 ratio lost enough in the belts to where it wasn't worth it.. so we're going with a 1:1 direct ratio.

The little turning axle running through the Igus pillow block was a testing stand to see what, if any gyroscopic forces would result from turning the prop.

And we're currently working to make sure we meet all the FIRST recommended specs on safety. IE you can't stick a finger in the mesh, and if you can it won't go far enough in to get hit by the blade. We'll do some measurements tomorrow to find out if we need to make a deep dish pizza pan.

I'll post a final picture of the conveyor system/ fan o' doom after build season ends. Let's just say.. it looks decently scary at this point.
