I am going to post this question here since my first two attempts to email top-flite direct resulted in no response. Anyway, I am trying to make an engine decision on this kit and would like to know if any weight was needed to balance it properly and where. I would like to incorporate that info into my decision. I have a Saito 82, Saito 91 and a .61 OS on hand. From what I have read and heard, it builds a little tail heavy so I was wondering how the prototype came out since the OS .61 two stroke was used. I believe there have been some changes to the kit to lighten the tail since the prototype but I am still curious how it originally came out. Otherwise, the manual and kit look great and I am ready to get it start over the holidays.

Thanks in advance for the help. Keep the kits coming!
