With a range of transmitters covering everything from beginner to expert, standard features that'll raise an enlightened eyebrow, and receiver prices that'll have you reaching for your wallet, RadioLink has been radio modelling's the best kept secret of recent times But not anymore! An updated version of the popular AT10, the AT10II, 2.4GHz upper mid-range, telemetry-capable transmitter now has 12 channels and, like its predecessor, offers a furure-proof feature-set to suit the intermediate / experienced model pilot. With an expanding hangar comes a requirement for a transmitter with an all-encompassing capability and enough channels to cope with the multi-functionality that complex model aircraft so often demand. Equipped with FHSS & DSSS frequency-hopping spread spectrum protocol you can be assured of a superior transmission rate, enhanced interference rejection and the peace of mind that comes with a rock-solid radio link. But, of course, there's far more to it than that. If you're an experienced flyer a quick look at the specification will confirm that this is all the transmitter wants for very little. Moreover, with amazingly competitive receiver pricing you'll realise that you really can afford to conveniently grow, or even re-equip, your fleet. Take a look at the full feature list and make special note of the AT10II's intuitive programming, colour LCD, telemetry features, wireless trainer link capability and striking good looks.
