Caliber 3 pitch range question

[JanFloris]

Hi. I have a Caliber 3 and I use a JR 2610 radio. I have a question (probably a stupid one). Most of the guys say that before you setup any curves ect on the radio, your pitch range shoud be more or less -9 to +9 (or -10 to +10) to start off with. I have connected all of my servos and linkanges, and found out that my pitch range is -11 to about +14. Since all of the linkage rods on the Caliber 3 are fixed lenght plastic ones, can I just set the collective servo travel ajust on my radio to lets say 80% on low and 70% on high to get the desired -9 to +9 for the start, or is there a machanical way of decreasing or increasing the amount of pitch? I know you change the pitch range ect with your curves on the radio, but I want it to be the same top and bottom before I make any ajustments on the curves.

take the ball links in a hole on the servo arm ... that will make it so there not as much movement over the arc of the servo

Even if ya do that then you wont get equal travel. The only way you can get equal travel is by adjusting the links on the head (which you have already said they are fixed plastic on the caliber). Can you adjust the rod going from the servo so that you get 0 degrees pitch at centre stick??? If not id therefore just leave it the way you have it and adjust in the radio so you get equal travel and then just set your pitch curves. Dont know if this might seem obvious but you have got a linear pitch curve at the moment havent you?

Off course the best thing to do would be to buy a link/rod kit so that you can fully adjust the model and set it up correctly.

Thanks for your replies. You can't adjust the rods going from the servo. The manual also says that you must use the second hole in the servo arm. (They also give a measurement if you don't have standard servo arms/horns). I think I'll just set the travel range of the servo on the radio so that it has -9 and +9. Hopefully it will then have 0 degrees in the middle! If it does'nt, then I'm screwed again!
So idealy, the servo must travel the same distance from center stick up and center stick down to get the same + and - pitch?

Yes.
If you're not able to modify the links on the head (any of them) then it could be hard work.
With a linear pitch curve on your Tx (set pitch curve as a flat line from 0% to 100%) put the pitch stick in the middle so that you have 50% pitch applied. You want 0° on the main blades here. With that set, you can then see what you're getting top and bottom, which would ideally be equal, but sounds like it won't be?

If you can't adjust the links, you will end up having to adjust your pitch curve to suit.
