RE: CMP P-51 50?
just to let you know I own the CMP 50 size Zero , the P40 , the corsair and the mustang P51 , they are all great fliers , they all have there ups and downs , the CG on all 50 size CMP is listed WRONG ! set it up correctly and you'll have a great model and a great flier , just make sure you go 25% the wing cord as a balance point and you will be very happy with the end result
