Check whether the aircraft you are trying to represent has a Spinner or not. many did not.
Let us know if you are looking for specific information.

Had one of these.. http://www.bing.com/images/search?q...409&thid=JN.B+OzmFio6YETJsb7hboBPQ&ajaxhist=0 many years ago
We have models with and without the spinners
And any kind of info is most welcome. Gear retraction/extending times, performance, weights, etc. Drawings of the cockpit as I am debating whether to do 3D gauges, but then again, 3D gauges are the norm these days. So in short, anything is welcome to aid in the development.
