Scenario:
On final for a landing and you are short and near stall--punch the throttle and hope you can go around.
You overshot the field on landing and you need to abort.
You decided to hover and want a vernier change in thrust to hold altitude.
I own a DX9 and one nice feature is the THROTTLE CURVE function.
Typical radio setup which is linear.
When you fly EDF's, as you increase your throttle, there is a lag in time (spooling up) before the thrust matches the position of the throttle. Some pilots on landing, choose idle and continue the approach. Getting into trouble (say, close to stall and crashing), they punch the throttle and it feel like an eternity before the thrust is plentiful. So your talking miliseconds that might get you out of the problem.
Now look at the throttle graph below.
First, I added a few points and now I have an exponential graph (I changed it in the data column) so when the throttle is very low in horizontal direction, you will see a I have a higher in RPM's in a short time. Compare x and y points(now you see why you need Algebra)
Result:
Now, at the low end throttle setting, a SMALL MOVEMENT of throttle drastically changes the RPM's (thrust) in a shorter time and gives you a quicker response.
Might save your $500 jet.
Point to make, yes, I know that you now have to learn to reposition the throttle location to keep the same thrust at the lower end. I always have the throttle open some until I start to stall.
"2 fer 1":
Notice the slope changes from 1/4 to about 2/3 to be shallow. I like to hover my EDF, so with a low slope, now I can use it to have very little change of RPM spooling so the plane doesn't drop out and end up crashing.
So, you can tailor your flying ability so you have a betterand less response (for me, just try the better first) that makes you comfortable. Try it, you might like it!!!!
