RE: Jets in Islip NY
There is still an active R/C field in Hecksher. When I visited this past summer, I drove around the park in a counter-clockwise direction and almost gave up when the field showed itself.
If weather becomes a factor, you can check out the museum at Republic airport and the Cradle of Aviation museum across the road from the Nassau Coliseum. I recommend both, but would choose Cradle of Aviation if time only allowed one choice.
