Flying Instructions Tiger Cub TM Attack the Sky with Shark Jaw Toys revolutionary Internal WingAircraft called the Tiger Cub TM and experience the power of vortex assisted lift and propulsion.The Cub TM makes flying easy with its high tech 2gRC Radio Control. Battery Installation CHARGING Instruction Sheets Because the Cub's batteries are used for both flight and recharging, they will need to be replaced every twenty flights. 1. Use a Phillips screwdriver to unscrew and remove the battery door. 2. Install six 1.5-Volt AA alkaline batteries (not included). Be careful to align the positive (+) and the negative (-) polarities with the corresponding markings inside the battery compartment. 3. Reinstall the door and tighten the screw. ChargerCordDoor Charger Cord On/Off Switch for Plane 1. Open Charger door and extend and connect charger cord to the plug in on the bottom of the Cub next to the On/Off switch. 2. Place the power switch on the fron of the controller to On, the red indicator light will come on. 3. Charge your Cub for two minutes. 4. Disconnect the cord and place back into compartment on the front of the controller . 5. Place the planes power switch in the on position. Pre-Flight Environment Check 1. Location - Fly the Cub in a large, open area which is free of trees, wires and buildings. 2. Weather - Fly on mild, sunny days. Do not fly in electrical storms, rain, sleet, snow, or other adverse weather conditions. Do not fly if the temperature is below 45 F/7C. In very cold temperatures, the plane will become fragile and the engine performance will decrease. 3.Wind Conditions-Do not fly in wind. Winds may overpower the Plane and make it difficult to control. In windy conditions, it may appear as though you have no control over the plane. Trouble Shooting Guide Questions? Email us at [email protected] or call our friendly flight technicians toll free at 1-888-492-8697 Important Safety Information Keep plane from face, eyes and hair at all times. Keep fingers away from the moving propellers. Do not launch plane near other people or animals. Use caution, make sure people around you know that you are playing with the Cub TM Recommended for use in large, wide-open,grassy areas. Do not fly near overhead wires, buildings, trees, or other obstructions, Be sure to fly on a clear sunny day . Do not fly in WIND. F lying in wind will sever el y diminish your ability to control the airplane. In some situations, where the wind is very strong, the wind may overpower the airplane and you will not be able to control it . Do not fly in adverse weather conditions such as electrical storms, rain, sleet or snow. Do not fly in temperatures below 45 O F/7 O C. Do not fly in temperatures above 113 O F/45 O C. For charging, use ONLY the Cub TM controller / charger -Do not use any other source to charge the Cub TM . Do not overcharge your airplane. Follow the charging instructions provided in the instruction manual contained within this package. Shark Jaw Toys PO Box 851325 Yukon, OK 73085.

EL205 TigerCub 49.820 ~ 49.900MHz Transmitter Operation Description Mar 10, 2007 Confidential Page 1 of 3 The Microprocessor (U1, Figure 1) reads input commands (SW2/SW3/W2/W3,Figure 1),and then encodes them to digital codes. The codes are sent to RF oscillator via pin 6 of U1, Q6, Q7 and then modulates 49.820 ~ 49.900 MHz carry frequency signal via Q1 (Figure 2) to achieve AM signal . Figure 1 The Radio Frequency of the transmitter is based on standard 49MHz AM citizen’s band. It generates low power 49.820 ~ 49.900MHz AM carrier frequency via major components of Q1, Y1, L1, C5, R4, R3 and R28 etc. (Figure 2). Please note that the value of the components may vary. Please see the attached schematics for more detail. EL205 TigerCub 49.820 ~ 49.900MHz Transmitter Operation Description Mar 10, 2007 Confidential Page 2 of 3 Figure 2 The AM signal (via capacitor C3) is passed to RF amplifier (Figure 3,Q2,C8,R9,and L2), which amplifies the signal and then couples the signal into the antenna (ANT1) via components C4,C6,L4,C7 and L3. EL205 TigerCub 49.820 ~ 49.900MHz Transmitter Operation Description Mar 10, 2007 Confidential Page 3 of 3 Figure 3 EL205 TigerCub 49.820 ~ 49.900MHz Receiver Operation Description Mar. 10, 2007 Confidential Page 1 of 3 The Radio Frequency of the receiver is based on standard 49MHz AM (Amplitude Modulation) citizen’s band. A low power local oscillator frequency of 49.820 ~ 49.900MHz, generated by components of Q1, C1, L1, C8, R5, C9, R3, C20 and T1(Figure 1), couple with antenna input via components of C2 (Figure 1) to discriminate RF signals from transmitter. Figure 1 The demodulated signal is sent to Q5 by R4 and C6(see Figure1) , and then is amplified by Q5,R14,C22, R11 and C21. The amplified signal is passed to the pin 11 of U1 via C13, R18 and is decoded to control commands by internal circuit of U1 (Figure 2) . EL205 TigerCub 49.820 ~ 49.900MHz Receiver Operation Description Mar. 10, 2007 Confidential Page 2 of 3 Figure2 The control command signals drive the motors via MOSFET Q2 and Q3 accordingly (Figure 3).
