I have 5 of these engines and they all run superb. Unfortunately the only FXII's available are the gold plated editions that cost an extra $25.00. The only place I know of to get them online is RCjapan.com. Unless you want to travel to Akihabara district in Tokyo. I see some FXII's online from US distributors for like $800, Don't be fooled. You can get the gold edition from RCJapan for $275.00
