RE: 42"wingspan p51d what size engine?
well the airframe and wings are covered in balsa sheeting so there wont be any sag!!.pluss from what ive read it certainly does shrink,the trick is to absolutely soak the paper 1st.ie in the bath so it expands slightly.ill stand to be corrected but thats what ive read in the reviews!!.then after its dried you sand it smooth and paint it!!.thanks for the input though and you may yet prove to be right as im only going by what ive seen and read about this method.how much does the gp 10 thunder tiger weigh out of interest?.
