The VU has three connections. The first — which
you have already connected — is the battery. The
second is the three-pin connector that looks much
like a servo connector. This one connects to the
NAZA pins labeled X3. The last is a four-pin
connector that plugs into the set of four pins labeled
LED. Route the cables down through the hole near
the VU and then back up through the hole in the
rear near the NAZA as shown in Figure 18.
As an option, both the NAZA and Futaba

flight controller, you can install your props. You leave
the props for last because you don't want your craft
flying away as you make adjustments.
Before you attach the props, you must balance
them. There are a couple of ways to do this, but I
have found the most reliable way is to use sand
paper to sand the heavy side of the prop. I will add
some more detailed instructions for balancing your
props on my website. You can also search the Web.

Each prop comes with a set of shaft adapter
inserts so that they fit perfectly on various motor
shafts. You want to use the 5 mm insert for both the
NTM and SK3 motors. Insert the adapter into the
back side of the prop. Next, insert the prop onto the
