Thanks for replying so quickly.
Just to clarify, in advance of your re-drawn plans, I think there should be a recess (notch) in the bottom of the fuselage side bottoms to take the bottom fuselage panel otherwise the panel would sit proud.
If I get to fly this model before you I'll post back, good or bad
Just out of interest I am building the N Sport at 123% in an attempt to ameliorate the effect of the heavier FB, wish me luck as this is my first scratch build after the Simple Cub kit.
