Step 6: Servo arms and balls
Here, you’ll need to take one of your MCPx balls you got from ebay (or your preferred source), and attach them to
the innermost hole on the servo arm, on the back side. See Figure 6. It’s hard to overstate how tiny these things
are, so don’t drop them. You’ll need a VERY tiny standard screwdriver for them.
Figure 6: The mini heli ball goes on the backside of the servo horn (which will be closest to the servo) on the
innermost hole.
