Interesting. If this were to happen to me after I received my 333 and I was operating legally and under 400 ft. following all rules and the chopper clearly went out of its way to "pursue" my UAV I'd file a complaint with the FAA, ensuring I grab any witnesses available and get their info for a civil suit to recoup my loss. If the FAA is going to make me fly legally and register my UAV, and jump through all the hoops, then I expect that chopper pilot to be investigated for endangering another aircraft and the public below.
