My Feedback: (3)

I have a older seaplane which was origonally electric, converted to gas, it is a 3ch flying boat type, I have tried several cg's and just can't seem to get it to fly right, I am wondering if the thrust line is wrong, what should it be, with the engine above and just in front of the wing, also, if someone has one, where should the cg go relitive to the leading edge?
I will post pics tomorrow.

Thanks
Ken
