Re-printed the blade mount with 25% infill PETG and now I can spin it up at about 25% power without too much vibration. Beyond that, it starts vibrating and I don't want to risk another shuriken.

P.S. the power consumption is between 3-4. I can't wait to get some grass to test it on!

Today I managed to wire up the motor driving the blade, mount the blade on, get with my feet on a chair, and give it a go!

What happened next was quite expected. I mean, expected when you prepare for failure. The blade started wobbling, I stopped the motor immediately, the blade detached from the motor, and flew away like a shuriken. Only to hit a cardboard box nearby. (Disclaimer: no cardboard boxes were harmed in this test).

I mean.. I hoped the 3d printed blade to motor mount would good enough, but hope isn't equal with reality. That needs rethinking and probably redesigning.

Next on the agenda, I noticed sparks in the motor:

My [learn by googling knowledge of electronics doesn't stretch that far, and I need to figure out if this is critical or not..

Of course these are not the best wheels to drive your robot indoors..
