This will keep the battery from shifting forward or backward during extreme maneuvers. 3. Install the battery hatch to the top of the fuselage. The magnet will hold the battery hatch in place. 30 4. Plug in the aileron (and flap) servo leads. Slide the wing dowels into the holes at the front. Use the two 6-32 x 1" socket head screws and two #6 washers to secure the wing.
Control Throws Low Rate High Rate Ailerons: Up/Down 1/2" (13mm) 7/8" (22mm) Elevator: Up/Down 3/4" (19mm) 1" (25mm) 2" (51mm) 2 1/2" (63.5mm) 1. Turn on the transmitter and receiver of your Ultra Stick 25e. Check the movement of the rudder, elevator and ailerons using the transmitter. Reverse the direction of the servos at the transmitter if necessary. Rudder: 2. Use a ruler to adjust the throw of the elevator, ailerons and rudder.
Center of Gravity Caution: Do not inadvertently skip this step! The recommended Center of Gravity (CG) location for the Ultra Stick 25e is 2 1/2" (63.5mm) behind the leading edge of the upper wing against the fuselage. After the first flights, the throws can be adjusted for your personal preference. Range Testing the Radio 1. Be sure to range check your radio before each flying session. This is accomplished by turning on your transmitter with the antenna collapsed. Turn on the receiver in your airplane.
Preflight Check Your Radio Before going to the field, be sure that your batteries are fully charged per the instructions included with your radio. Charge both the transmitter and receiver pack 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.
Flying the Ultra Stick 25e You will find the Ultra Stick 25e to be a solid, honest sport model. It is capable of handling windy days if you choose. Flight times with the 1800mAh Ni-MH battery will be around 9–10 minutes. When using the Thunder Power 4200 3S2P battery, flight times of close to 17 minutes are common. Ensure your CG is set according to the manual and power up the aircraft. Move your throttle trim up slowly until the motor just begins to spin.
Flying the Ultra Stick 25e Once lined up for takeoff, apply full up elevator and apply full power in a smooth fashion. As the model accelerates and the floats come up on step, relax the elevator slowly. You will find as you relax the elevator through half travel the model should break water and begin a gentle climb out. Re-trim the model for level flight with the floats installed.
