1. unarmed transmitters rule 2 will then search for any other active transmitter frequency broadcast and will sync to the lowest channel number Rule 3 is the rule that is followed for syncing Air Model 1 transmitters with G1 or G2 receivers These rules allow G1 and G2 receivers to operate with each other while delivering a good measure of convenience for Air Model 2 users and continued usability of Air Model 1 transmitters in the same flying area It s still good to keep track of who is running on what channel but with the Air Model 2 transmitters once you have figured out who is on what channel you probably wont have to worry too much about frequencies or stepping on each other s channel number Transmitter Mixing Modes There are several user selectable Mixing Modes available on the transmitter See Fig 8 You select your mixing mode when you Switch on your transmitter The mixing mode you choose will be saved in memory until you make another selection even if you switch it off The position of the Right joystick at startup controls what mixing mode will be selected The factory default mixing mode is Normal rudder and elevator mixing this can also be selected at startup by holding the Right joystick to the right for about 2 seconds When you Startup the Transmitter you can hold the Right joystick to the left to select Negative Exponential mixing that might be useful to dampen your joystick controls f2. These mag nets are also used as electrical conductors The terminals of the Bahoma cell are protected from shorting to each other by a plastic Safety guard See Fig 1 On the front of the transmitter slide the 3 position switch to the mid dle position to put the transmitter into it s Charge mode The LED inside the charger door will be blinking rapidly Slide the hinged clear polycarbonate plastic charger door downwards to unlock it and then lift it open Attach the Bahoma cell to the corresponding magnet ic terminals The Bahoma cell will click into place on the charger by magnetic attraction and with good electrical contact The LED inside the charger will now glow brightly Close the clear charger door and Slide it up to shut it with a small click Your cell is now charging and when the bright LED goes dim the cell is fully charged and ready for use Charge time is about 60 minutes typically The charger is set to charge at 75mA for the 10mm Bahoma standard for LP90 cell and is set for about 22mA rate for the 5mm Bahoma spacing for LP30 cell as found with the Butterfly RTF sets See Fig 2 Periodically clean the magnetic electrical terminals of your cells to ensure good electrical contact See the troubleshooting section of this manual for instructions on doing that they do require cleaning from time to time Important Notes about Lithium Polymer Batteries The lithium polymer rechargeable battery should not be used
