• When transporting or temporarily storing the battery, the temperature range should be from approximately 40–100°F. Do not store the battery or model in a hot garage, car or direct sunlight whenever possible. If stored in a hot garage or car the battery can be damaged or even catch fire. • Do not over‐discharge the LiPo flight battery. Discharging the LiPo flight battery to a voltage that is too low can cause damage to the battery resulting in reduced power, flight duration or failure of the battery entirely. LiPo cells should not be discharged to below 3.0V each under load. In the case of the 2‐Cell/2S 7.4V LiPo battery used to power the Gamma 370 you will not want to allow the battery to fall below 6.0V during flight. The included 20‐Amp Brushed Motor ESC (AZS1210) features a ‘soft’ low voltage cutoff (LVC) that smoothly reduces power to the motor/power system (regardless of the power level you have set with the left‐hand/throttle stick) to let you know the voltage of the battery is close to the 6.0V minimum. However, even before this reduction in power, if you find that more than the typical amount of throttle/power is required to cruise or climb you should land the model and disconnect the battery immediately to prevent over‐discharge. And while it is possible to power the model up and fly again after the soft LVC occurs, this is NOT recommended. Continued discharging can result in reaching the 5.0V ‘hard’ LVC which may cause permanent damage to the LiPo battery resulting in lost power and flight duration during subsequent fights (or failure of the battery entirely which is not covered under warranty). Also, it is not recommended that you fly to the soft LVC every time you fly. Instead you should be aware of the power level of the battery/airplane throughout the flight, and if at any time the airplane begins to require more throttle/power than typical to maintain cruise or climb you should land the airplane and disconnect the LiPo battery immediately. Constantly discharging the battery to the soft LVC can still cause permanent damage to the battery so it’s best to use a timer or stop‐watch to time the duration of your flights and to stop flying at a reasonable time before the soft LVC is reached. IMPORTANT NOTE: DO NOT LEAVE THE LIPO BATTERY CONNECTED TO THE ESC UNLESS YOU ARE READY TO FLY. IF THE BATTERY IS LEFT CONNECTED TO THE ESC ...

NOTE: In some cases there are plastic ‘caps’ installed on the ends of the control sticks to protect the foam airframe and other components during shipping. Be sure to remove these caps to expose the ends of the sticks before using the transmitter. Low Battery Voltage/Power Indication When the AA battery voltage/power drops to a level that’s too low for safe continued operation, the red color LED indicator will begin flashing. DO NOT use the transmitter or fly when the red LED indicator is flashing and immediately install new AA batteries before using the transmitter or flying. Antenna Position/Orientation The RF output signals transmit best/strongest from the shaft of the antenna rather than from the tip. As a result you should never point the tip of the antenna directly at the model. Also, the transmitter antenna can be rotated up to 180° and folded up to 90° so be sure to hold the transmitter and position the antenna as needed to ensure the best possible signal transmission. Control/Servo Reversing The 6HPA transmitter features control/servo reversing functionality for the aileron, elevator, throttle and rudder channels. The control/servo directions were set correctly at the factory for the Gamma 370 RTF, however, in case the controls are operating in the wrong direction, or you use the electronics in other models later on, simply change the position of ‘Servo Reverse’ switch for the channel(s) as needed. Delta/Elevon Mixing Located to the right of the ‘Servo Reverse’ switches is a switch that activates/deactivates the optional‐use ‘Delta/Elevon’ mixing. No such mixing is used for the Gamma 370 so please be sure this switch is in the OFF/lower position (failure to do so will result in improper control and the inability to fly the Gamma 370). However, if using this transmitter with ‘flying wing’, delta or other airplanes that ‘combine (mix)’ the elevator and aileron (often known as ‘elevon’) controls you can move the switch to the ON/upper position. 19 ...

Page 38
At the desired altitude you can level the airplane off by pushing forward slightly on the right‐hand stick (‘down’ elevator) until the airplane is flying level. Then, reduce the left‐hand/throttle stick position/power to approximately 1/2 to 2/3 for cruise flight. You’ll find that it only takes relatively small/minor rudder inputs to change direction in flight. Remember to keep these inputs as minimal as possible as significant inputs, such as moving the stick all the way to the left or right (and holding it there), could result in over‐control, loss of orientation and/or a possible crash. If you find the airplane constantly climbs, descends or drifts/turns left or right without any control input you’ll need to make adjustments to the trim settings using the trim levers on the transmitter (you can find more information regarding the location and function of the trim levers in the ‘Flight Controls and Trimming’ section of this manual): o If the airplane is drifting/turning to the left or right adjust the trim for the rudder (using the aileron channel trim lever located immediately below the right‐hand stick). o If the airplane is climbing at ‘cruise’ throttle/power, add down elevator trim (using the elevator channel trim lever located immediately to the left of the right‐hand stick) and/or reduce the throttle/power setting slightly. o If the airplane is descending at cruise throttle/power, add up elevator trim (using the elevator channel trim lever located immediately to the left of the right‐hand stick) and/or increase the throttle/power slightly. It’s important to continue making trim adjustments as needed until the airplane maintains straight and level flight with very little to no control input. Also, if this is your first airplane model it may be best to enlist the help of an experienced airplane pilot to trim the model for you before making your first flight. A properly trimmed airplane is much easier to fly! When the airplane is properly trimmed practice making shallow (approximately 5‐15 degree bank) turns by using a small amount of rudder to roll the airplane then a small ...
Page 39
Sharper turns (approximately 15+ degree bank) will require more rudder and elevator input. Try not to excessively bank the model beyond 30‐45 degrees as doing so can cause the airplane to lose altitude very quickly. If at any time during flight you feel like the airplane is drifting out of/beyond your control, simply release the elevator and rudder controls while maintaining approximately 1/2 to 2/3 power. In most cases, and with enough altitude and space, this will allow the airplane to return to nearly level flight on its own. Also, if the airplane is flying too high or too far away, lower the left‐hand stick/throttle completely to power off the motor and allow the airplane to descend to a more reasonable altitude/position. At typical cruise throttle/power settings the Gamma 370 will fly for approximately 8– 10+ minutes per charge (when starting the flight with a fully charged battery). However, we strongly recommend using a timer to keep track of your time in the air and to land after approximately 5–7 minutes to ensure you have plenty of power to practice landing approaches and to ‘go around’ if needed. IMPORTANT NOTE: You can lose motor power abruptly if the voltage of the battery drops too low! Lowering the left‐hand/throttle stick and power to less than 1/2 to 1/3 will allow the airplane to enter a shallow descent. This is helpful if the airplane has climbed too high and when it’s time to set up for landing. To land, point the nose directly into any wind at an altitude of approximately 100–150 feet above the ground and approximately 150‐300 feet away from the desired landing area. Reduce the throttle/power to 1/3 as you descend slowly to approximately 20‐30 feet, then lower the throttle/power to 1/4 or less. At approximately 2‐4 feet above the ground lower the throttle/turn off the power completely while allowing the airplane to descend naturally. Just before the airplane contacts the ground add a small amount of up elevator to bring the nose up and ‘flare’ for a smooth landing. Later on you can practice landing with a small amount of throttle/power to help smooth out the approach and touchdown. However, you must be sure to lower the throttle/turn off the power completely if the prop comes into contact with the ground. ...

View the trailing edges of the ailerons and wing from directly behind again and continue adjusting the length/position of the pushrod/clevis until both ailerons are centered appropriately. NOTE: In some cases it may not be possible to exactly center the inboard and outboard portions of an aileron relative to the trailing edge of the wing. If you find this to be the case simply adjust the length/position of the pushrod/clevis to ‘split the difference’ between the inboard and outboard portions relative to the trailing edge of the wing. NOTE: You should always rotate the clevis until the pin is perpendicular with the control horn to ensure the pin is not under any excessive load/pressure when inserted in the hole and during operation. In some cases it may not be possible to ‘exactly’ center the surface mechanically while properly aligning the pin. In these cases be sure the pin is properly aligned then adjust the position of the trim lever slightly as needed. Also, it will likely be necessary to make further adjustments to the position of the trim lever during flight as most surfaces do not end up in exactly the centered position when an airplane is trimmed properly for actual flight (but ‘centered’ is still the best starting point). Also, we strongly recommend installing the included ‘clevis keepers’ to provide added security for the clevises. Typically you can carefully slide the keepers over the clevises when they are not connected to the control horn. Then, after connecting the clevis to the control horn and ‘snapping’ the clevis together you can slide the keepers into a position that does not allow them to ‘bind’ against the control horn/bracket during movement of the surface. Attaching the Aileron (Aerobatic) Wing Before attaching the aileron (aerobatic) wing to the fuselage, plug the 3‐wire lead from the rudder servo (which was recently unplugged from the ‘AILE’ channel of the receiver), into the ‘RUDD’ (rudder) channel of the receiver. Confirm that the rudder is functioning correctly and moving in the right directions based on moving the left‐hand stick to the left (rudder should move to the left) and right (rudder should move to the right). IMPORTANT NOTE: If using the 6HPA transmitter included with the RTF version Gamma 370 be sure to move the ‘RUDD’ (rudder) channel ‘SERVO REVERSE’ switch (located on the bottom front of the transmitter) to the ’REV’ (reversed) position before proceeding. This will ensure the rudder channel/servo is operating in the correct direction. ...
