i stripped the grip servo on the lynx4 and in the process, snapped one of the linkage parts. It would be nice if the linkage was available instead of an entire assembly @ $40.00.
I was holding down a button in RIOS to close the gripper with out pressing 20 other buttons to set up my approach to an object to pick up. Here is my example of a better servo GUI other than a RIOS track bar or button with NO SERVO DELAY.
It’s a design I like to call: keep the noobs safe 
I can replace the broken linkage part if you can tell me which part it is. If you can spring for shipping, or on your next order, I will certainly replace the part for free.
