Currently there are two indoor locations I fly at.
Friday nights 9-11pm in Newtown at the NYA

Two basketball courts in size with aprox 30ft ceiling. Hardwood floor isn't very forgiving, but good for umx size planes.
i fly my Mini scout there but it's a little cramped. Between 3-8 guys a week show up.
Saturday mornings 6-8am in Danbury at the Sportsdome

Biggest inflated dome in New England (I think). 4 turf soccer sized fields in size 90ft high in the center. Would be nicer if they didn't have 8ft high nets between the fields, but that doesn't affect you too much. Between 5-15 guys a week show up.
Both venues charge $10 a head per day.
When the weather is nice there is a large group of guys that fly in New Milford on Sunday Mornings from dawn to 10am or so. Electric only. Not a club, but there is a core group that has been going there for years, nice guys. on a great day there might be over 20 people there.
The field is behind Pettybone School and adjacent to a Kimberly Clark factory. I put a pin in the Flight Test Members map
