Ironic observation, Noel. I had forgotten this thread, and my post above.
In the 5-1/2 years that have passed since then, the Scottsdale shop to which I referred has closed and the “huge new store” opened. It had a three year run and closed suddenly, unexpectedly, and infamously overnight. Long gone for a couple of years now.
No new shops have opened here, in the fifth largest metropolitan area of the United States. The remaining shops are struggling and without RC car and drone business a couple of those would probably be gone, too.
