The yellow wing has a 15" root chord and 9 1/2" tip chord with a 44.5" span...The red wing is 18 1/2" root and 14 1/2" tip with a 49" span. Both have a straight leading edge.

I will check and see what i can find on tail volumn coeffecient, i have heard a general rule of thumb is for the stab to be roughly 25% of the wing area which i know im way below this.

Thanks again
