    Comments: I cannot understand the negative reviews of these great servos. Mine are great.. accurate, reliable, and very smooth BUT I know mine are genuine Tower Pro. I can only believe that as there are so many counterfeits and then that's what you are buying. The guy that is waiting for replacements from China...do you honestly think they are genuine Tower Pro servos. They are some cheap crap of unknown origin that cannot be compared with genuine Tower Pro. .. and then you go an put them in an expensive model and wonder why it nosedives..Geeze!!! People..get real.. if you pay peanuts .. if they are from china .. then chances are they will be crap. For a few bucks more you get the genuine article.. You pay a fortune for you models and put your heart and soul in building them...then you start to penny pinch and put in crappy controls. You deserve all you get if you dont buy the genuine article.

    Comments: The old versions were great, but anything purchased in the last two years WILL FAIL when put into use. Much better off to go with something like a Futaba 3115 now. Also... Many counterfit TowerPro products in circulation.

    Comments: Awefull. Fast but not smooth. Slightly jerky rotation. The old MG90 were much much better . Centering is slightly off, but thats the same as most cheap servos.
