I have seen a few with the Zenoah G23 , but they are not rockets like most people want , it will fly nice but not hover or have unlimited vertical. There are probably better choices depending on what you want. The New G26 from Zenoah is suppose to have more power than the G23 and only slightly heavier. With either of these you will need to arrange your radio differently for balance.

I have a G23 in my Goldberge Extra 300 which weights a few ounces over 10 lbs. and flys great with almost unlimited vertical and certaintly has more than enough power for doing the complete IMAC routines. HTH
