But dont you essentially x out the speed of the servo when you add in expo? I mean you get a really fast servo that runs at .09 and then you add 30-50% expo what are you gaining in the normal flight control range? Arent you giving that need for speed back to get a softer or slower response as the curve dictates? I mean the things you are looking for in a servo are response and reliability.


The only real advantage on paper I am seeing that digitals do that analogs cant do is
i.e... if you move the stick to say,, full up elevator sitting on the ground and you get 12 degrees of throw, when you get up in the air an analog servo may only actually be giving you 10 degrees because the air is pushing the servo back, so you push a littel more not even knowing you are having to add more input than you "should to get 12 degrees".
but your brain tells your hand to adjust to get the plane to do what you want it to do anyways,,

A digital in the same scenario adjusts the signal to overcome the feedback from the airflow and forces the servo to the exact position it want the servo to be in, but how in the world can you tell? I mean your hands arent going to be able to tell 1 or 2 degrees of difference in the stick input versus what you see the plane do.

So the analog sends a given amount of power and doesnt actually know what the servo position is, right?
And the digitals send out a given amount of power, get feedback of the actual postion of the spindle/servo arm and add more power to force the spindle/servo arm to the position it wants...

IMO RC flying is 95% visual, you have no other physical connection to the plane but sight, all your corrections are done by sight. The sound of the engine gives some information to make you feel secure but you react to what you see ..

When the plane is in the air, you dont know how much deflection the surface has, you only know what you see the plane do, so you give stick correction to make the plane in flight look and react the way you want it to.

I can see where you could see the difference of two identical planes set up identically with identical radio setups one with analog and one with digital. Just seems like if you wanted more response with less stick input you could just take expo out.

Im gonna have to eventually try it and see for myself, I can see it already. And as Bob said Im a sucker for the old addage of "you get what you pay for.

Sorry to ramble, just got me thinking.
