the first time, we suggest removing them and "hardening" the
threads in the plywood with a drop of thin CA glue. Once the glue
has set, put the mount back in place and tighten the screws firmly.
❑
26) Reinstall the brushless motor into the motor mount. Insert
the back end of the motor shaft into the mount, and then use a
1.5 mm wrench to tighten the two set screws.
❑
27) Before the ESC is installed, the red (positive) and black
(negative) battery wires coming out of the ESC must have a
proper battery plug installed. The battery plug is not included in
this kit - there are various types available, so it is a matter of per-
sonal preference. We like to use the “Deans Ultra” plug, as shown.
Solder the battery plug on to the red (positive) and black (nega-
tive) wires of the ESC, being mindful of the polarity. Solder the
mating connector to your flight pack battery, again being careful
to get the polarity correct.
❑
28) Connect the ESC up to the motor - red wire to red wire;
white to white; black to black. Later, when running the motor for
the first time, if you find that the motor is turning in the wrong di-
rection, simply switch two of the wires to change the direction of
rotation.
❑
29) Mount the ESC inside the nose compartment of the air-
plane. Use a section of the supplied sticky-back “Hook-&-Loop
Tape” (Velcro®) to hold the ESC in place. We mounted our ESC
up high on the right fuselage side, as shown in the next photo.
RECEIVER & BATTERY INSTALLATION
For this section, you will need the remainder of hook-and-loop
tape, your receiver, the aileron Y-Harness, and a charged flight
battery pack.
❑
30) You can mount the receiver either on the top or bottom of
the plywood cabin floor, using a piece of hook-and-loop tape to
keep it in place. We mounted ours on the bottom.
❑
31) Plug the aileron Y-harness into the aileron slot of your re-
ceiver. Plug the elevator and rudder servo leads into their correct
slots. Also plug the ESC into the throttle slot in the receiver. (Your
radio manual will tell you which slots to use in your receiver).
❑
32) Exactly where you should locate your battery pack will de-
pend on the final balance of your airplane. Every airplane (espe-
cially balsa wood models) can vary in balance. You won’t know
exactly where to put your battery pack until the airplane is com-
pleted, and you check the final balance on page 14 of this manual.
There is plenty of room inside the Rascal EP-49 fuselage to ac-
commodate practically any balance situation. The battery pack
can go all the way forward against the back of the firewall, or back
in the cabin behind the landing gear (in which case you would re-
locate the receiver to the top of the plywood cabin floor. In most
cases we believe you will find, like we did, that the battery pack
will end up on the floor of the nose compartment, as shown in the
next photo. Use a section of hook-&-loop tape (Velcro®) to hold
it in place during flight. Make sure that the battery plug is in posi-
tion to be easily plugged into the ESC.
