  • The "pins" are fiber glass, very springey, I found out the Polymorph is quite absorbing / dull as spring compared.
  • At the tips it has steel reinforcement, as it was getting shorter and shorter legs :)
  • The reason for the long stick in front is that I experiment with moving the battery / weight.
  • The motor is from an old RC,I have locked the axle, no dif drive.

More to come, and then better images, and video not made with my cell.. I guess :)

I'd REALLY whish I had a high speed camera, that would make analyzing the jumping SO much easier. This is too big and crazy jumping for any strobe-analyzing.

 

 

jumps like a bull on hot coal
