That sounds about perfect. Thing is how do I calculate whether the controls are going to bind? That seems like it's a hard thing to accurately predict so I'm building everything how I think it should be built, with calculation for spars and torsion and anti-drag etc. and then testing the controls work as part of the load test.Yes a good question! I guess being able to get full aileron control movement upto rough air and or manoeuvring speed and one third control deflection above that?
There's a few interesting presentations on the Royal Aeronautical Society website - it had never occurred to me even to check it out even though it's just down the road.
