I'm testing a new robot , using ezbv4 and hitec D845WP servos with lipo 7,4 V batteries. (I never used these servos and such high-current batteries before). These servos are very quick, expecially with lipo batteries. So, when I program an action, I can't get a smooth and and slow movement, no matter how  I set delay, step and speed in the action  window editing area.  I can't get a continuous movement. The servos are so  fast, that they perform, with any setting , only a series of very fast and precise steps. Indeed, they follow exactly the staircase generated by ezb. I can  get a continuous movement only by  clicking  "transition to" , from a frame to another , in the Auto Position screen, with a speed =50. But in the action window editing area I can't set  a speed  of 50, but  only  a maximum of 20. What can I do ???
