I have another question. Ive seen some robots that have flipping arms (Matador, Hydra) instead of flipping panels (Chaos 2, Thermidor 2). From what Ive seen, the arms are more powerful than the panels. I really like flipping arms, and noticing the above I like them even more now. However, Ive seen flipping arms that are really tiny, almost like toothpicks, and some that are really wide. What would be an ideal shape for a flipping arm.
