1. This manual will help you assemble your
B-25 Mitchell. Let’s start with the
installation of the brushless motors. Plug
the three motor wires into the three ESC
wires. Do not worry about the plug-in
order; we will check motor rotation in a
later step.

2. Feed the ESC and motor wires back into
the engine nacelle and slide the motor
onto its motor mount.

3. Tighten setscrew with 1.5mm hex wrench
to hold the motor in position.

4. Set the two engine cowls aside till a later
step.

5. Locate the various Y-connectors. See
photo for identification. The triple
connector is for the retracts (Ch. 5). The Y
that does not have the signal wire is for
the lights.

6. Photo shows the root end of a wing panel
and identifies the various connectors.

7. Locate the triple connector and plug in
one leg to the connector labeled “5”.
Please make sure to correctly orient the
signal wire on the connectors.

8. After plugging the wires together, tape the
connection with clear tape to prevent them
from disconnecting.

9. Locate the fuselage and apply a bead of
glue to the inside of the main wing
opening.

10. Apply glue to the root end of one main
wing panel.

11. Feed wires into the fuselage at front of the
wing opening and insert the wing into the
fuselage. Make sure that the wing is fully
seated into the opening. When the wing is
in the correct position it will look like the
photo, the flap line will be adjacent to the
fuselage.

12. Insert the wire wing stiffeners from the
other side of fuselage and repeat the
gluing process for the second main wing.
