Dear Alasdair, I am trying to get a 1:6.2 scale Macchi MC-72 Schneider racer floatplane airborne. Not having access to anyone locally with any experience of floatplanes and after reading your book I would like to put some of my concerns to you.rnUsing the C of G calculator in your book, the range comes out as 26-31% of MAC, but the compensation for floats brings that forward by 8% of MAC (twice your Sonas example) to 18-23% MAC. Am I Right? It all adds up to a heap of Lead!
