Yes, it seems these Kyosho planes are not available in the US anymore. Had the same problem with my Kyosho bf109 when I tried to order a wing kit from Tower. Heard a rumor that Kyosho may bring them back but this could be rumor. To find one, you may have to look at Ebay or RCU.
Your first sentence is almost correct. If you had said "Kyosho planes are not available throught the Hobbico empire anymore" it would be correct. Here's the Kyosho US site:

Unfortunately, for those who like Kyosho, the choice of planes appears to be rather sparce.
