Yes.

The traditional way is to use a different hole on the horn (servo arm or control horn), but many modern transmitters allow the adjustments to be made through the turn of a potentiometer or in software.

Hope that helps, John

I agree with John, but would like to add one thing:
I think it's better if you don't permanently set extreme control throw changes on the Tx. The servos will work best if the Tx throw/end-point setting is near-ish to 100% (optionally with dual-rates reducing it further some of the time). Extreme values can either place an unnecessary extra strain on the servo or give a noticeably non-linear response. Personally I try to keep the Tx within about 85-110%, and adjust the horns to get further changes.

Adjusting control throws ?

Another dumb question, but...When they talk about adjusting the control throws, are they talking about putting the control rod/wire into a different hole on the servo arm or by making an adjustment on the transmitter ?

As Stuart says.

Set the throws 'mechanically' using servo arm and control horn positions, and only use the TX settings if really necessary.

Same applies to centre positions (if your radio allows you to adjust these) ... you should first get the best you can by moving the servo arms on the shafts (often rotating them 180 degrees gives a different position).

On mechanically adjusting linkages:

If you want to decrease the throw and you have the option of moving out a hole on the control horn or moving in a hole on the servo arm, it's better to go out a hole on the horn. Contrariwise, if you want to increase throw, it's better to go out a hole on the servo than to go in a hole on the control horn.

The reason for this is because any slop in the linkage will have less of an effect.

I do agree with making mechanical adjustments before making changes to the transmitter settings, but I thought it might be me just being old fashioned!

Regards to all, John

...or put it another way....

Where possibe it's best to use the longest servo arm and the longest horn on the control surface. This reduces the impact of any play in the holes.

also...

The splines in the center are arranged so that by rotating the arm through 90 degrees you can fine tune the neutral position to approx a quarter of one spline position. (Eerrr now that I think about it you can't rotate and refit the arm at EXACTLY 90 degrees).

I agree with hooking up to the arms at the longer positions to minimize the effects of slop.

This may be old hat, but I've been slicing off 1/16" slivers of plastic tubing and pushing it over the end of the z bend and hitting the outside with a drop of thick CA. When these are pushed up semi firmly, there's essentially no slop and no binding.

The directed squirt tubing that comes with spray lubes is great. I've made wheel retainers in this way and I land on dirt, stones and pot holes and have bent and re-bent the axles many times and the retainers are still fine.
