David Davis Posted April 7, 2014 Share Posted April 7, 2014 Posted by jeff2wings on 03/04/2014 22:41:05: Dutch roll is better described as P.I.R.O or pilot induced roll oscillation or in car driving terms "a tank slapper" Actually it's a term used in motor cycling.

Stephen Grigg Posted April 8, 2014 Author Share Posted April 8, 2014 Yes I understand Dave thanks.The OS 40 wont fit its to narrow and its to much to alter the model.Ive worked out a Saito 45 is the one and a friend Tony Prince who live in South Africa has one he is prepared to sell me.The better news is the engine is with his sister in Devon so itll soon be with me.

Rob Ashley Posted April 13, 2014 Share Posted April 13, 2014 Chaps, Dutch Roll has absolutely nothing to do with the pilot. Dutch Roll is the natural response of the aircraft to gusts and the resulting roll to yaw couple. Some aircraft roll more than yaw whilst others yaw more than roll. It is always present just more or less noticeable in different aircraft. Hence one of the reasons for an autopilot, which is designed to null out the error. The aircraft does not tank slap like a motorcyle. Quote Link to comment Share on other sites More sharing options...
