Anyway, no
one from the FAA ever came by to complain and we used to fly there on a
pretty regular basis.

There have been r/c vs. full scale conflicts around an r/c club at a
turf farm located south of HFD, where the FAA has complained. No
accidents that I know of, but complaints have been lodged. The
particular club has a large "giant scale" membership, so I suspect that
many of the planes weren't as close to full scales as the full scale
pilots may have perceived.

On the other hand, I've flown r/c @ active, open airports, with
permission. In that case, we simply used a spotter and landed the r/c
stuff until the full scale was clear of the runway. Kind of like street
hockey. If a plane appears in the pattern, someone yells "plane", and
we stop, and then someone yells "game on!" when the full scale is clear.
Other times, we'd have scanners or handhelds listening for approach calls.

Woodstock, CT, now a private field, even lists r/c activity in NOTAMS
and on airnav.com.

Before the current stadium was built, r/c was frequently flown at P&W's
East Hartford facility. Tethered balloons were flown to demonstrate
max. altitude to r/c pilots, to prevent conflicts with HFD.
