Re: Fake Futaba servos

I’ve heard many times that when something appears too good to be true then it usually is and in this instance it certainly was.
I scored 4 of these 3003 servo's on Ebay at a rather cheap price but when they arrived I discovered why (some rigorous ground testing paid off for sure).
The units I received looked very similar to the fake ones shown here and have some severe performance issues.
The potentiometers that provide position feedback to the units were extremely bad which caused the centre position to vary 55 degrees from centre on each side (yes, you read that correctly, 110 degrees variation overall!) and made position control totally impossible.
The other issue was the motor strength, the servo was very week, almost to the point of acting like one of its 12gm little brothers.
I did try my luck with the seller (who was upset when I threatened to leave feedback mentioning his misleading sale of Fakes) and he promised to send 2 new ones after personally testing them.
Well, they arrived and were even worse than the original 4.
I learned many lessons in this exercise, I still love Ebay but wisdom, discernment and common sense are invaluable
