Read the document, i dont agree with some of his issues, reasons (a) Issue on control throw and Expo, in real aeroplane we have something called a non-linear mechanism, it is designed for a approx 65% expo, it all depends on the CG margin (See my aerodynamics thread) and moment arm. eventaullly it should behave linearly not throw linearly (b) at high speed i will want vey flat centre for the simple reason it shoudnt over react to my control input (in real aeroplane we manage this with a mechnism called 'Q' feel) (c) Obviously smith is not real life aerobatic pilot probably, with 1000s of hrs of aeros he woud know what he is talking, bottom line, whatever you fly it should feel good, (1) Cross coupling should be removed (Mix spoiler as much as to nullify this) (2) it should feel right when you fly Going by some book written by somebody based on his own experience is only applicable for him/her, your style of flying could be different, fly the way it feels right to you listen carefully, aeroplane talks to you in every manoevure, set p-mixes accordingly, wrong p-mix can crash your model That will be my advice, of course this book can be a starting point |
