So, as it turns out, the price quoted on Maxx Wheels on Stunthanger hobbies is PER WHEEL. So when you order, take that into account. I thought I ordered 2 sets of wheels but was told that the quoted price is per wheel so I only got one set.
Well, that's OK. But it is something to be aware of. It's in the fine print on the site, but I didn't see that before. The money wasn't a big deal but I thought I was ordering 2 sets. So if I order again to get the other pair, it's more shipping. Sigh...
