Doug,


A-MEN, BROTHER!!!! You 'splained it so simple even my three year old son understands!!! Seriously, very good post----Full of usefull information based on mathematical facts, not guestimates!!!!


As each day passes more and more sport flyers are getting into 3D aerobatics. The average sport flyer buys his Funtana, or whatever, to join in on the 3D craze. What the average sport flyer may or may not understand is that a plane set up with the wild max 3D type throws may not ideally be set up for being flown at max speed, pattern or IMAC. To get those extreme throws that may be required for 3D flight, one may have to set up the servo linkage to such extremes that the mechanical advantage of the lingkage becomes compromised. What I'm saying is that the throws that work for 3D may cause your control surface to flutter when the model is flown at a higher speed. No defect in the model....Just a set of circumstances that could explain some of the failures (flutter) of ANY plane that has extremely large control surfaces for 3D flying and less than ideal mechanical advantage linkage setups......After flying nothing but jets for the past 15 years I can't wait to join the 3D craze with my first 3D plane---A DA-50 powered Chip Hyde Double Vision.....[8D]

Again, good post!!!!
