Being of an excitable temperment, I posted

which Ollie commented, probably rightly, that it was too far away to be worth taking. Obviously with the quality of plane pics posted by Ollie and Stephen Fox, I am prepared for a general comment 'if you don't have the right equipment and dedication to go to displays, leave off this subject', but would appreciate some guidelines if possible
1: Ollie started with what I had sussed too late, ie spot focus, whereas mine is usually set to central area focus
2: maximum exposure time to 'stop the props'?...looks like 1/640 or 1/800 from another shot I had of same copter with better detail, but only boring grey sky behind
3: if you can't get that speed don't try?
4: minimum lense spec?
5: Duncan gave a guideline of proportion of frame for bird pics, is there one for plane pics
6.....Nn what else?

Is there a place for technically sub-standard shots if they capture some sort of 1 off event of interest, as I would say is the case in other categories??
