Sure thing...
What radio do you use, if you do not mind me asking. Not that it makes a difference, I am only interested. I will not mention any names here,.
This is what I do:
I have the following flight modes. And the modes are listed in order of priority.
1. High Rate
2. Roller Rate
3. Snap rate
4. Low rate
5. Default mode
I will explain each one.
1. High rate = this is used to taxi onto the run way. Right before taking off, I switch it to low rate. I take off, and fly. I fly precision. When i do a hammerhead, I will switch it to high rates. As soon as the Airplane rotates, I remove the high rate, and place it back in low rate. High rate has maximal rudder deflection, just enough that does not touch the elevators!! HA HA!! aileron rate is same as low rate, and elevator rate is more than low rate.
also, allow me to add, I use a 3 position switch, that is on the top of my right stick. I can take a picture, if you want me to.
2. Roller rate = Only used to do a roller. This has way much less aileron throw, as compared to low rate., and it has more rudder throw and more elevator throw, as compared to low rates.
3. Snap Rate = this is activated by logical switches. IF the left stick and right stick, at the same time, are buried into the corners, then it activates the logical switch. SO if I am flying on low rates, and I want to do a snap, and bury the sticks, the moment the sticks reach maximal, the switch turns on, and it will increase my aileron throw, as compared to low rate, and it will increase then decrease elevator and rudder.
4. Low rate = this is my precision rate, which allows me to do everything I want to do precision wise. Rolls, point rolls, loops, loop elements, etc.....
the moment I am making my approach to land, I will place it on low idle and land on low rates. the moment I touch down, I switch it on to high rates (again, the switch is already on my finger tips), and use full up elevator, and this will push the tail down, and help slow down the airplane.
as far as travels go, for precision, I like to maximize the servo resolution, but at same time, need to have enough throw, to be able to make it snap.
For the elevators, the servo arms are maybe 1.25"
the servo arm on the rudder is 1.5"
Aileron is also 1.25"
the distance from the hinge line to the control horn hole, is going to be either equal to, or greater, than the servo arm distance from the the servo output shaft to the ball link. meaning, you want the ratio to be either one or less, that is, you do not want the servo arm distance to be greater than the control horn (hinge line to hole on the horn).
(we do this on 3D airplanes, using mega strong servos, but doing this, decreases the resolution.)
there are other things to look at, and that is, try to make the mechanical set up, as close or equal as possible, when servos are ganged on one surface, and then use the radio to do final matching. DO not try to make it all with the radio, as this can result in more binding, at different degrees of movement. meaning, you can match it in center and end points, but it may bind in between.
But the better the initial mechanical set up is, the less likely it will be that binding will occur.
I hope I have not confused you or made things more complicated, and, if you already know all of this, then please forgive me If it sounded simplistic.
Best regards
