Hallo Dick,

I have always respected your views here on the Pattern Forum. I also agree with the technical issue in that more servo throw is always better.

My disagreement comes for your attitude towards a math approach. Being and mechanical engineer in the aviation field ( 50% of my dailly work is control system design for full size gliders) I feel you are wrong. Maths (if done correctly) will always get you to an answer faster and more accurate and will allow you to get a feel for a problem before you start fiddeling.

Some systems are so complex that no amount of fiddeling will allow you to understand or optimize it. A correct mathematical model will point out stuff that you cannot obtain from practical experience although practical experience is VERY important.

Still what you say about more servo throw is corect.
