Team Bitza - Banshee

[Dan-27]

Hello

After re-configuring what remained of Spinza Mk I into Ankle Biter for last years BW champs I've decided to try building a couple from scratch for this years competition. The first will be Ankle Biter MkII (horizontal bar spinner) and the second will be my first stab at a drum spinner, Banshee.

I wanted to try out a few new ideas with the drum spinner (Innovation pushing tried, tested and reliable options aside!) The first new idea is building suspension into the wheels by remove material around the motor mounts and rely on the Titanium flexing and not bending.

The second idea I could use some advice with, having seen a miniature turbine spun to 80,000 rpm with compressed air I starting thinking if it would be possible to power a spinning weapon with compressed air. My thoughts are to have either a small EDF or 3D printed centrifugal compressor blow high speed/pressurised air into veins to turn the drum. Although there would be a tiny amount of torque I'd hope that the drum would build inertia which could deliver the punch, in a similar way that you may drop the power to the motor before an impact.

My brain can't work out if this is at all possible, any thoughts much appreciated.
