e)

Tack glue the firewall in place. Recheck once more to make  sure
that the front of the firewall is at the  correct  distance  from  the
back of the motor mount box. That distance  plus  the  length  of
your motor must equal 5-3/8”. When satisfied it is correct,  glue
the firewall securely to the rest of the motor mount box.

❑

26) Remove the X mount plate from the back of your motor and

center it on the firewall.  Once you are sure it is properly located, mark
the mounting holes with
a  pencil.    Set  the  X
mount  aside  and  drill
out  the  mounting  holes
with  a  7/32"  dia.  drill.
Install  four  M4  Blind
Nuts in the holes, on the
back side of the firewall.
Put  a  couple  drops  of
glue  on  the  flanges  of
the blind nuts to secure
them  to  the  plywood,
but  be careful not to get
any of the glue in the threads.

❑

27) A long stick of balsa Tri-Stock is provided to reinforce the motor

mount. Measure, cut and glue pieces of triangle stock in all the
corner joints inside the motor mount box.

❑

29) If you have not already re-attached the X mount plate to the

   back of your motor, do so now.  Then use (4) M4 x 16mm Socket
   Head Mounting Bolts and Lock Washers to  bolt  your  motor  in
   place on the plywood motor mount box.

❑

30) Install your ESC

a)

Solder appropriate battery connectors (not supplied) to the

battery leads of your ESC.

b)

Decide on a good location for the ESC in the nose of the

    airplane.  The most likely  location  is  against  the  fuselage   side,
    out of the way of the  battery pack.   Mount   it  to   the   airplane
    structure using a method of your choice - like double-sided  tape
    or Velcro® (neither of these are provided). In this case, the Castle
    Phoenix Edge 75Amp ESC fit perfectly on the bottom of the motor
        box, and was attached with a pair of servo screws (Not furnished).

❑

28) Bolt the plywood

motor mount box to the
Fuselage   with   M4   x
20  mm    Socket-Head
Bolts     and    M4   Flat
Metal  Washers.    Note
that two   access   holes
have been  provided   in
the bottom  corners   of
The  firewall   to   allow
easy   access   for   your
hex wrench.
