I've just bought one Rob! The 'new' price for the DSX11 is excellent! Can't find any info on the differences between the DSX11 and the 11X Zero though - be interesting to see what mods McGregor made... And also what support/upgrade routes they will offer. Apart from the integrated RF module on the DSX11, from what I see on videos about the 11X, 'My List' ( a customised function list) is customisable for each model, but on my DSX11, 'My List' is the same for all models. Only difference I can pick up so far. It fits in the hands very well for a finger & thumb (or nipple tweaker...) flyer like me, and probably even better for a thumb flyer - I really like the ergonomics and balance of it, and the looks are ok too! It's DSM2, which despite being not truly frequency hopping is tried and tested and works with all the Spektrum and BnF stuff, but the high end DSM2 receivers are getting expensive now.
