yes he does still use helicopters. On the rally in November 2015 in Sarasota Florida, he arrived in a helicopter with the TRUMP name on it. After he exited the helicopter he made a brief speech out in the field where us over flow crowd was 5k-7k people that didn't get into the 4k capacity auditorium at Robart's Arena, and then invited groups of kids to go for a helicopter ride. This went on until he returned outside after his main speech in the auditorium.
I think that might be my face in the bottom right of the photo with the sunglasses on lol.
