What a remarkable coincidence, I just started flying a Goldberg Protege .60 ARF recently! (Nathan flew mine):

It's worth also pointing toward MinnFlyer's excellent review of the Protege .60 ARF here at RCU:

Unfortunately Tower Hobbies has the Protege .60, along with several other Goldberg ARFs, listed as "Temporarily Unavailable." I'm only guessing, but I think they wanted to sell out the existing inventory because they were covered with Ultracote/Oracover. Now that they're "temporarily unavailable," Hobbico is (hopefully) ordering another run of ARFs but the new ones will likely be covered with Monokote.
The Protege .60 ARF, Senior Falcon ARF, and Skylark 70 ARF are all on "Temporarily Unavailable" status and all three are wonderful airframes. Hopefully they'll be back in stock soon with one kind of covering or another.
