I almost bought 1. The deal actually fell through after I took delivery of the heli. Anyway I found info not real easy to come by and parts even harder to find. It looked like a very nice heli though. I'm sorry to say that I have since deleted all the info I had collected, but it did all come from RCU so a search may bring up some of the threads I had started. This was about 2 years ago, BTW.
