I think the issue is the same for any new (or established, in some instances) club, 'regular' or pee-pee.

A couple of folks (Rebsix and k3 Valley Flyer) have opined against the notion. To them: it's clear that you would not not want to belong to a SS-only (I use that term because SS R/C gear is now available in bands other than 2.4 GHz, e.g., 900 MHz and projected for 500 MHz) club. I think more on-topic would be a reply to the question "should AMA allow SS-only chartered clubs, if that is what the club members want?"

The example of why a club with a potential site in proximity of another club might want to has been discussed. Another example is a club located where interference on the allocated 72 Mhz band is too severe to continue operations. This happened to an AMA chartered club in Balboa Park in San Diego. The toll of models lost to RF interference became so alarming that the club decided it would be irresponsible to continue, citing the risk to other park users of out-of-control models and attendant liability risk to themselves. This was a few years ago, before availability of SS R/C and the club/flying site was abandoned, so this is hypothetical:

If the situation faced by this club happened today, should the club be allowed to go SS-only and so continue to exist?
