RE: are these servos okay to use
I had a hs 81 servo in my sig mess 109 on rudder and stripped it out. I replaced with a turnigy 1160 I bought five for the price of a hitec. working great. I have a hxt900 for throttle on my 96inch davis d1w gas powered. I have hxt12's on my control surfaces they are not fast but for the Davis it will be fine it is a parasol and does not fly fast anyway. Just big! I use lots of those "Off Brand" servoes with a great degree of success. I will continue do do so when I can buy 5 for 1 why not? I can do more airplanes for the same amount of money. I have hxt 900's on all surfaces in a chipmunk and they work just fine.
The one person that stated they get rebranded is correct. I won't hesitate to use them.
