BATTERIES
Notes on Lithium Polymer Batteries
When misused, lithium polymer batteries are
significantly more volatile than alkaline or Ni-Cd/
Ni-MH batteries used in RC applications. Always
follow the manufacturer’s instructions when using
and disposing of any batteries. Mishandling of Li-Po
batteries can result in fire and explosion causing
serious injury and damage.
During the course of building your Rhapsody 25e we
suggest you use a soft base for the building surface.
Such things as a foam stand, large piece of bedding
foam or a thick bath towel will work well and help
protect the model from damage during assembly.

it, securing the propeller.
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.
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
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.
3

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.
Do not remove the canopy hatch by lifting it up by
the pilot. You may accidentally remove the pilot.
After the first flights, the CG position can be adjusted

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.

Control Throws
1. Turn on the transmitter and receiver of your
model. Check the movement of the rudder using
the transmitter. When the stick is moved right,
the rudder should also move right. Reverse the
direction of the servo at the transmitter if necessary.
2. Check the movement of the elevator with the
radio system. Moving the elevator stick toward
the bottom of the transmitter makes the airplane
elevator move up.
3. Check the movement of the ailerons with the
radio system. Moving the aileron stick right makes
the right aileron move up and the left aileron move
down.
4. Use a ruler to adjust the throw of the elevator,
ailerons and rudder. Adjust the position of
the pushrod at the control horn to achieve the
following measurements when moving the sticks to
their endpoints.
Elevator High Rate (100%)
Up 1-inch (25mm)
Down 1-inch (25mm)
Rudder High Rate (100%)
Right 2-inch (50mm)
Left 2-inch (50mm)
Rudder Low Rate
Right 11/2-inch (38mm)
Left 11/2-inch (38mm)
Measurements are taken at the inner or
widest point on the control surface.
These are general guidelines measured from our own
flight tests. You can experiment with higher rates to
match your preferred style of flying.
Travel Adjust and Sub-Trims are not listed
and should be adjusted according to each
individual model and preference.
Preflight
Check Your Radio
Before going to the field, be sure your batteries are
fully charged per the instructions included with your
radio. Charge the transmitter and motor battery
for your airplane. Use the recommended charger
supplied with your particular radio system, following
the instructions provided with the radio. In most
cases, the radio should be charged the night before
going out flying.
Before each flying session, be sure to range check your
radio. See your radio manual for the recommended
range and instructions for your radio system. Each
radio manufacturer specifies different procedures for
their radio systems. Next, run the motor. With the
model securely anchored, check the range again.
The range test should not be significantly affected. If
it is, don’t attempt to fly! Have your radio equipment
checked out by the manufacturer.
Double-check that all controls (aileron, elevator, rudder
and throttle) move in the correct direction.
Check the radio installation and make sure all the
control surfaces are moving correctly (i.e., the correct
direction and with the recommended throws).
Check all the control horns, servo horns, and clevises
to make sure they are secure and in good condition.

Daily Flight Checks
As you taxi out to the runway you will find the ground
handling to be very gentle and easy. The wide stance
main gear and low angled stance keeps the model
tracking very straight through all aspects on the
ground. Once you are lined up on the runway ensure
you have your throttle trim set to where the motor is
spinning at a low idle setting. This is your flight idle.
Apply power smoothly and steering with rudder. You
will find the tail to come up very quickly and the model
will accelerate straight ahead effortlessly. Once up to
speed pull back slightly and ease the elevator control
to establish a solid shallow climb to altitude. Once at
altitude you will want to trim the model for level flight
at about ¾ power. Once trimmed try some basic stalls
to become comfortable with the model’s handling.
You will find the model stalls very gently and forward
routinely.
You will find the model is quite aerobatic and can
perform loops, rolls, inverted flight, and all the other
basic aerobatic maneuvers with ease. Landings are a
thing of beauty as you glide in and settle gently to a
3-point touch down. The model also likes to be wheel
landed, the choice is yours. We hope you enjoy your
Rhapsody as much as we enjoy ours.
Happy Landings!
Before each flying session, and especially with a new
model, it is important to perform a range check. It
is helpful to have another person available to assist
during the range check. If you are using a Spektrum
transmitter, please refer to your transmitter’s manual for
detailed instructions on the range check process.
1. With the model resting on the ground, stand 30
paces (approximately 90 feet) away from the model.
2. Face the model with the transmitter in your
normal flying position. Be sure the throttle is in the
full down position and plug the flight battery into
the speed control.
3. As you move the controls, watch to be sure the
airplane’s motor and controls operate smoothly.
You should have total control of the model at 30
paces (90 feet).
4. If control issues exist, call the appropriate
Horizon Product Support office (see page 22) or
go to horizonhobby.com to find a local Spektrum
distributor in your country for service if using a
Spektrum radio system.
battery. Do not fly below the manufacturer’s
recommended voltage. To do so can crash
your aircraft.
When you check these batteries, ensure you have the
polarities correct on your expanded scale voltmeter.
2. Check all hardware (linkages, screws, nuts,
and bolts) prior to each day’s flight. Be sure that
binding does not occur and that all parts are
properly secured.
3. Ensure all surfaces are moving in the
proper manner.
4. Perform a ground range check before each
day’s flying session.
5. Prior to starting your aircraft, turn off your
transmitter, then turn it back on. Do this each time
you start your aircraft. If any critical switches are
on without your knowledge, the transmitter alarm
will sound a warning at this time.
