Horizon Hobby UK are advising DX6i owners to check their transmitters as a number of poor stick potentiometers have been fitted to some sets. There's an easy process that owners can followwhich will highlight whether their set is affected and full details can be found at www.horizonhobby.co.uk - just go to the news page for the link.
In a nutshell, radios with a date code of 809E, 810E, 811E, 812E should be carefully checked. If your radio has a code showing 809EUK, 810EUK, 811EUK or 812EUK then it has already been checked and passed by Horizon's engineers in the UK.
A service report form should be downloaded from the site before the transmitter is returned via retailers or directly to Horizon Hobby themselves.
