Is it really something necessary you have to buy or just a luxury?
All these functions can be adjusted through RX.
If you have to buy it will you mention any performance difference.
And what about: Hitec HFP-20 Digital Servo Programmer / Tester

i doubt many people have a servo programmer i would say its luxury

Ok fine with me but ...
I am asking so because I can't realize the use of it...
It's something that expands the RX settings or it unlocks
some menus of the servos

And what about: Hitec HFP-20 Digital Servo Programmer / Tester
The hitec programmer only programs hitec servoe but will test them all. It works great with multi servo flight surfaces such as large scale planes. I find it especially helpful on eCCpm heli, due to the fact that you can set center and eliminate subtrim with jr radios. The more subtrim in the radio, the more interaction you get.

It can also eliminate the dead band so you can get very precise servos. You can also set end points and reverse the servo. Also itcan set how fast the servo moves which is especially helpful with retracts and such.

hope this helps.

Hitec servos come programed with zero deadband which is fine for 99% of the applications, but when you have multiple servos on a large control surface it's very useful to increase dead band. Basically if multiple servos are attached to the same surface they will fight each other and kill themselves as well as battery especially if your linkages have no slop. Increasing the dead band basically introduces "virtual linkage slop" which could be precisely adjusted so servos don't butcher each other and control surface looses minimum accuracy/precision.

If you have a radio that doesn't have all the bells and whistles then programmable servos may be cheaper than buying an expensive radio. With some programmable servos you can even control the speed, so lets say you want your scale landing gear retracts to go up and down nice and slow and your radio doesn't support that feature, you can accomplish it with programmable servos. That's just one example, but there are probably a few others.

Dr.Rivet:

Are you sure that hitec servo's come with zero deadband? From my research of hitec servos and the programmer, it seems that people that have both are stating that they decrease the deadband in most cases. Maybe the newer servos are different? I was researching this topic when the 6965's originally came out....

It is not accurate to say "Hitec servos come with zero deadband." I have multiple Hitecs with some amount of deadband. Also, you reprogram the center positions of the servos to match each other so they don't fight. You don't decrease the deadband to do that. I have been told that deadband decreases as the input voltage goes up. That is why servos like the 9252 only like 4.8 volts. At higher voltages, the deadband is nonexistant and the servo never finds a center position it likes. It looks jittery.

Hitec servos have deadbands from 1-4 usec, they do not have zero deadband. When Hitec had the "double" centering issue it was because the deadband was to big so it would center different depending on which way the servo moved.

No you would not use the program to minimize deadband for centering issue. You would set the deadband then set center.

Hyperion Servo are programmed via USB with adapter, you can slow them down, center them etc.. pretty neat.

Hitec told me that their servos come from the factory set at
their minimum dead band. The 6965 is 2us. Unfortunately it cannot
be set to 1us even with the new low cost programmers.

ServoCity lists the factory settings for Hitec Servos. Some
are 8us.

Being able to center them is an advantage.

I onced looked at the hitec servo programmer but decided not to get it. It was pricy.

it can also be used with some servos to set the end points.this is useful on gyros with no limit function (e-flite g-90,e-sky, some align,zoom, telebee ect)

it really makes tail set up much easier and more precise,on gyros with no limit function

Can you be more specific because I have a Spartan DS760 and I really have no mess with endpoints...
Because generally speaking I 've never used before servo prog/s or aim to...but information is better than ignorance

you didn't set your end points so the servo doesn't bind at the end of travel??

on most newer gyros and some older gyros there is a limit function,the 401 has a limit pot the spartan and hitec/logitec use the rudder stick while in programming mode(others do I'm sure, but those are ones I am using)

the e-flite G-90,e-sky ect ect have no limit function on the gyro itself so you have to use servo arm ball distance to avoid binding at the extremes,the holes are not always where they need to be and drilling holes is not always possible,so sometimes you dont always get full throw.

if you use a programmer with programable servos you can limit the servos throw to exactly where you need,giving you full throw but no binding
