Phone the toll free number for Heli-World. They have a computer software package designed for changing the settings in your TX.

Like most radio gear that come with RTF helis, you will find the TX/RX here is very limited. You may be better served by just getting a better basic heli radio set like the Futaba 6EXH or somehing similar from Spectrum or JR or Hi-Tech.

WIth this TX/RX, you will not have to purchase comnputer interface software to change any perameters in the TX as it is already part of the TX's internal software, and you will also be able to use it with any large electric or nitro heli in the future.
