Modifying Hitec HS-755HB 180° rotation

[mimichris]

Hello,
Excuse my bad English but I am French.
Do I have a servomotor Hitec HS-755HB, do I want that he/it turns 180°, can I add two resistances of 2KOhms of every side of the potentiomètre will be sufficient as I read him on other posts ?
Thanks,
Mimichris

I do not think it can work! Inside the servo there is a stub on the gear that make the servo can turn 90 max. Why don't you buy a GWS-S125 or equivalent that can turn 180 or 360

Darn, I was just reading an article online yesterday about exactly this. I'm looking for it now. A direct link is http://www.amya.org/us1mconst.pdf and there are some servo mods shown on page 51 and page 53 of the pdf file.

For several alternatives, refer sub sections "Servo - Modify for Retracts, Number of Turns, Ganging & Continous Rotation " and "Servo - alterations, calculators, databases, repairs, convert to an ESC or winch & FAQ." under ""Radio Systems, Accessories, Alterations and FAQ'' on my web page.
