Quoted from gweempose:
What does getting to the opto entail? Do you have to remove the entire Vengeance mech?
Gweem I got my lower right opto out with out removing the vengeance. The lower screw that holds the opto on is a PITA to get to! I have a 1/4 drive spring extension with a phillips head that I was able to get the screw out with.
