18 E-flite Rhapsody 25e ARF Assembly Manual
Always balance your propeller. An unbalanced
propeller can cause vibrations to be transmitted
into the airframe, which could damage the
airframe or other components as well as
produce unwanted flight characteristics.
 2. Use the propeller adapter to secure the
propeller to the motor. Slide a 3/32-inch hex
wrench through the hole in the adapter to tighten
it, securing the propeller.
 3. Connect the battery and speed control. Use
the transmitter to check the operation of the
motor. If connected as described earlier, the
motor will spin counterclockwise when viewed
from the front of the fuselage.
 4. Use medium CA to glue the pilot in the cockpit
as shown.
 5. Place the canopy hatch on the top of the
fuselage. The front of the hatch has pins that key
into the front former, and magnets holding the rear
of the hatch to the fuselage.
Do not remove the canopy hatch by lifting it up by
the pilot. You may accidentally remove the pilot.
 6. Apply the decals to your model using the
photos on the box as a guide. Use a spray bottle
filled with water and a drop of dish washing
detergent sprayed on the airframe will allow easier
repositioning of the decals. Squeegee the excess
water from under the decal and allow them to set
overnight before flying your model.
Center of Gravity
An important part of preparing the aircraft for flight is
properly balancing the model.
Do not inadvertently skip this step or
property damage and injury could occur.
The recommended Center of Gravity (CG) location for
your model is 3 3 /
4
to 4 1 /
2
inches (95 to 114mm) back
from the leading edge of the top wing as shown with
the battery pack installed. Mark the location of the CG
on the bottom of the top wing with a felt-tipped pen.
When balancing your model, support the plane upright
at the marks made on the bottom of the top wing with
your fingers or a commercially available balancing
stand. This is the correct balance point for your model.
Make sure your model is assembled and ready for
flight before balancing.
Adjust the motor battery as necessary so the model is
level or slightly nose down. This is the correct balance
point for your model. You should find the CG to be
very close with the battery installed as shown in this
manual. Mark the location of the battery on the battery
tray using a felt-tipped pen so it can be returned to this
position if it is removed from your model.
After the first flights, the CG position can be adjusted
for your personal preference.
