For those asking for specs here is a description (we can take a close up of things if youd like to add those as well).
8 performance wheels (hex shaft) with wedgetop tread (

Custom 1:1.2 up conversion modulox gearbox using VexPro ceramic coated aluminum gears driven with a single CIM
Flywheel is a 10 plywood saw blade with the teeth ground off & attached to the aluminum performance wheel it also acts as a guide to keep the Frisbee flat as it travels around the wheel
Bottom outside wall is made of aluminum angle back notched every 1 and pop riveted to the polycarbonate
We line the inside of the outer wall with wedgetop
Another piece of aluminum angle is added to keep the discs flat rivets are used to attach้ both the wedgetop and top angle to the base wall in ends up looking like this:
Compression of the outer aluminum wall is 15 the added wedgetop makes it about 14 5/8
We made 10 out of 10 shots from 18 last night
We can document the RPM of the wheel and accuracy later as well as provide some close up photos
