Mav, Check out Rcgroups.com , there you will find some cases. At least two model makers had to cancel their planes, GWS had to cancel 747 and theri p-38 and P-40 should have come out half a year ago, but now their release date is unavailable.
Mostly this will hit American model makers because some model makers in another continents donīt give a watermelon about legal rights, which in this particular case I find somewhat justified...
