RCU Forums - Nitroplanes flying dreams Extra 330lp

Hi All,
I may have posted this request in the wrong forum yesterday for which I apologize.Hopefully someone in here may be able to help,
I have just bought a Flying Dreams Extra 330 LP from a swap meet. It looks not to have ever been flown and in perfect order. Unfortunately there was no instruction manual with it so I am a bit stuck with critical information such as recommended control throws and more importantly the CG. ( I would guess at 25% back from front edge of wing but???)
Anyone out there who has had one of these and can enlighten me?
Many thanks in advance.

R.
