I do a lot of work for City governments, they all, without exception, require a minimum of $1,000,000 in general liability, and some want more. Ask you agent what a MILLION dollars will cost to get added to your policy to cover model airplanes. I suspect that it might be just a touch more than $58.
It is to be noted that the $1,000,000 is for ORGANIZED sports such as little league and youth soccer. Not for individuals just playing catch base ball or kicking around a soccer ball. Same could be demanded of an R/C club as it is an ORGANIZED activity demanding the same considerations as other ORGANIZED sports -- control of public property to facilitate their activities.
So the argument for the same liability coverage as the AMA to use a public facility as an individual is spurious and extremely questionable.
