I ended up purchasing two completely different helicopters, one a micro drone helicopter that I am sure that it is about HO scale or even smaller. It vaguely looks like an older style Bell helicopter. I was not really satisfied with the decision of this purchase, but the price was right and I might have some fun with it. It is also small enough that any damage resulting from crashes should be minimal. The second purchase I made was a fairly nicely detailed Bell 47 helicopter in 1:43 scale which is slightly larger than O scale and this model does not fly and is just for show. I am waiting for both purchases to arrive.
