It is a Northstar,The wing tips don't have the sponsons like the original.It also has the horiz. stab.
I new when I flew mine the first time it was nose heavy and took weight out of the nose to get it to fly right.If it balances on the C.G. I would start there then if you have to fly it with a lot of up elev.,I would back off the nose weight an ounce or two at a time.A nose heavy plane will fly again,a tail heavy plane flys once.
