It's a standard marketing practice.
Take a look at the Tower servos. See any Futabas?
Happens all the time.
But they're not always the same. Very often, the cheaper one will be cheaper inside. Sometimes not. It's your gamble.
Bingo!!!
While many components are made in the same factory...and appear very similar... they will be made to the specs and cost limitations of the company placing the order....
as Da rock says.... its a gamble....
I will say this... I used some hobbico serovs on a profile katana and while they worked OK, they didn't center too well and they were VERY noisy.......doesn;t mean they are better or worse (because I know of a couple Hitec servos that don't center well at all....) just what I saw.....don't remember which ones they were though...
