It must be the CCPM model, I have owned 3 46's-never the 60 though. I was strongly into Xcell's when I flew 60 sized heli's. The Ergo 46 was a good heli with the 46, but great with the OS 50 I have in it now. It got rid of the running issues I encountered. But I believe the Ergo 60 would be a grand heli. The top frames on my 46 cracked due to the 46 issues. After going with the 50 and not upgrading to the new hi-dollar frames I have had 0 issues with the frames using the 50 OS. Well I'm off to fly at a FF at the Childrens Home today Ltr.
