It seems that you don't really believe our comments on the HS-81 based on your comment about the big Saito. My suggestion is for you to go ahead and use a HS-81 on your throttle and report back to us how long it lasts.
I'm not implying I don't believe you but I was surprised at how quickly everyone condemned the idea. I thought the mini servo, noting this one is 2Kg rated, would be more than adequate for a simple throttle setup.
You still don't seem to understand. It is not a torque issue. The HS-81 has way more than enough power to drive the throttle. The problem is that it is too delicate to be used in a high vibration environment. The HS-81 was designed for sail planes and works great in that low vibration application. It also works fine in small electrics, I have 3 in one of my electrics.

I am not surprised at how quickly everyone condemned the idea. Most of these people probably thought that you were asking an honest question and wanted an honest answer based on experience. It seems to me that you really were wanting validation for something that you were going to do anyway regardless of the safety aspects.
