❏1. Before operating your MICRO ULTRIX Biplaneyou will need to charge the NiMH battery pack in theairplane.To do so, make sure the airplane is switchedoff (OFF is toward the front of the airplane).❏2. Turn on the charger. Plug the charger cableinto the charge socket on the airplane. The chargerwill plug in only one way.❏3. Switch on the charger to begin charging. Thered LED will flash as long as the battery is charging.Once the battery is charged, the red LED will turnoff and the green LED will turn solid. Be aware thatduring the charging, the green LED will turn onmomentarily. Charging should take 5 to 10 minutes.• Make sure the battery is fully discharged before charging.• Never leave a charging battery unattended.• Never let the battery charge until it feels hot. A hotbattery is an overcharged battery. Only let thebattery get warm to the touch.• A properly cared for battery pack will last a longtime. If the battery pack is continually overchargedor charged at too high of a rate, the life of thebattery pack will be shortened.ATTENTION: The product you have purchased ispowered by a rechargeable battery. At the end of itsuseful life, under various state and local laws, it maybe illegal to dispose of this battery into the municipalwaste system. Check with your local solid wasteofficials for details in your area for recycling optionsor proper disposal.This product contains a chemical known to theState of California to cause cancer and birthdefects or other reproductive harm.BATTERY RECYCLINGSAFETY PRECAUTIONS FORCHARGING BATTERIESNOTE: DO NOT CHARGE THE AIRPLANE’SBATTERY UNLESS IT HAS BEEN FULLYDISCHARGED. To discharge the battery, turnon the airplane and the radio and apply fullpower until the propellers stop turning.CHARGE THE MOTOR BATTERY5
Before attempting to operate or fly your MICROULTRIX Biplane, please make sure you fullyunderstand its operation outlined in this section.Note: The following is a detailed description ofhow you will control your MICRO ULTRIXBiplane in flight. Please study it carefully so youwill become familiar with the operation of thetransmitter before you head for the flying site.Your transmitter controls the height of the airplaneby operating both motors and the direction of theplane by slowing down either the left or right motor.❏1. First extend the transmitter antenna. Thenswitch on the transmitter and make sure the greenlight is on.❏2. Make sure the airplane’s battery is charged.❏3. Move the switch located on the left side of thefuselage backward to the “ON” position.CAUTION: Stay clear of the propellers once theairplane’s switch is turned on.❏4. Moving the left stick forward will cause bothmotors to run at full power. At this setting, the planeshould climb at a 10-15° angle. NOTE: For most ofthe flight, you will be pushing the stick forward.❏5. Moving the right stick to the right will cause theright motor to slow down. This will cause the planeto turn to the right.HOW DOES THE MICRO ULTRIXBIPLANE WORK?BEFORE GOING TO THE FIELD6
If you have an airplane that follows either path (A)or (B), cut the sides of the elevators as shown in thephoto above.If your airplane follows path (A), bend the elevatortabs up.If your airplane follows path (B), bend the elevatortabs down.❏3. Repeat step 2 until your airplane follows path C.D = Airplane turns left.E = Airplane turns right.If your airplane turns to the right (E) during glidetests, bend the rudder to the left.If your airplane turns to the left (D) during glidetests, bend the rudder to the right.RUDDER TRIMMING8
Range check your radio before each flight. Switchon the transmitter first and then the airplane. Havea helper hold the airplane. With the transmitterantenna collapsed, walk 50 feet away from theairplane. Move both control sticks, checking that themotors run and turn off following the control stickmovement. If you still have control over the airplane,it is safe to extend the antenna and fly the airplane.If you do not have control of the plane, make surethe batteries in the transmitter are fresh and thebattery in the plane is charged. Also, make sure thewire antenna is extending out the back of the plane.Do not cut the antenna wire on the plane.If you have never flown an R/C airplane before, werecommend that you get help from an experiencedR/C pilot. Most R/C clubs have training programsthat will help you learn to fly quickly. If you cannotfind an experienced pilot to help you learn, thefollowing will help you get your airplane into the air.1. First, turn your transmitter power switch “ON.”This immediately puts you in control. Be sure toextend your antenna completely.2. Move the airplane’s switch to the “ON” position.Caution: Stay clear of the propellers.3. Have an assistant help with the launch. Move thethrottle stick (left) forward so that both motors arerunning. Have your assistant launch the plane intothe wind.4. Allow the airplane to climb at a 10-15° angle for afew seconds before turning it. This will allow theplane to gain altitude and air speed.5. To turn the MICRO ULTRIX Biplane, move theright stick to the left or right until the plane hasturned. When the MICRO ULTRIX Biplane is movingaway from you, moving the right stick to the left willmake your plane turn to the left. Moving the rightstick to the right will make the plane turn to the right.6. When the plane is coming toward you, moving theright stick left still causes the plane to turn left, but itappears to turn to your right. In short, you have toreverse the way you control the right stick. A good wayto familiarize yourself with the controls is when theplane is coming toward you, turn your body so that youare facing the same direction the plane is going,looking over your shoulder at the plane. Now when youmove the right stick left the plane will go to your left.7. Don’t let the airplane get too far away from you.The farther away it is, the harder it is to see what theplane is doing.8. When learning to fly, it is best to keep the planehigh so that if you make a mistake, you haveenough altitude to correct the mistake.It’s a known fact among fellow R/C pilots that yourairplane will land. It is up to you as to where andhow it lands.1. The MICRO ULTRIX Biplane will fly forapproximately 3 to 5 minutes at full throttle on a fullycharged battery. For your first couple of flights werecommend that you attempt to land before themotors stop. This will allow enough power to abortthe landing and try again if you miss your landingarea. When the transmitter battery power is gettinglow, the green light will turn OFF. Once the green lightis off, it is time to land your MICRO ULTRIX Biplane.2. During your first flight, while at a high altitude,turn the motors off and notice how the MICROULTRIX Biplane reacts. This will give you an ideahow the plane will react during landing.3. To land the MICRO ULTRIX Biplane, fly downwindand a few feet past the landing area. Gently turn intothe wind and turn the motors off. The plane will start tocome down.
