8cc stunt tank - different version

In case you can't tell, its not made by Cox, it was cut from a floppy disk on Jason's die-cut machine. I made one several years ago like this one and I was surprised on how good it performed. It unfortunately self destructed after probably 10-15 runs. Since the original was hand cut with an X-Acto knife, I had trouble reproducing an exact copy. Until Jason came along with his die-cut machine, It was basically abandoned. The reed in the picture seems to be performing close to if not a little better than a rectangular Mylar reed, it still needs a little more adjustments to its design. I haven't worked on the design since last summer. Health issues with a close family member halted that and many other things.

Tru, the oval mylar reeds seem to do best for me. The steel reed in the picture would be heavier than others, even heavier than the regular steel oval like Bernie and Matt sell. And I would think a heavy reed would be more sluggish to move than a light one, possibly floating at high RPM. They all become deformed after a while, so that's not an issue for me.

Everyone has their favorite. This oval mylar is mine:
