Looks GREAT! Those are some very nice shots you've taken.
About that Racer's Edge servo arm. Can you tell me if the linkage hole is tapped for a 3mm Screw or 2.5mm?
Also, How does the Locking spindle part work out, does it clamp around the Spindle and Also use the standard screw to hold it on the servo ??? 4 total screws? Thank you, Sir.
