Hey Jeff,
Your a fantastic resource for info!
I found out what the conversion was that the guy used. It was made by a Japanese company called Correct. I'll have to research if they still exist. Very nice looking conversion.

He has photos of the conversion listed under Older helicopters on his website.
I think the Shuttle Plus 2 CCPM kit that you refer to would most likely work for me. I just want this new shuttle to be all that it can be.........so to speak.
I'll keep my old ZX in stock form and just enjoy it for what it is. Its already taught me more than I could have ever imagined in such a short time.
