ran the Xmaxx today and the 18/46 seems to work properly - didnt bash it though ... now the stock motor fans do click occasionally - I assume they should be running all the time? it seems they try to start but dont start on an interval - at least by the looks of it or its just in impulse and they dont actually run all the time but only when necessary - could someone elaborate on their behaviour?
also, I installed the telemetry stuff - well, not sure about it yet but it clocked 138mph once, so not sure about its GPS accuracy - I did correct the gearing in the "model setup" for the "calculated" speed but this makes me wonder ... need to fiddle with it a bit more ....
edit: fan problem sorted - all working again
