Throttle servos
My throttle servos are more often than not what I would call "hand me down". What I mean is that, as servos have progressed in torque and speed, when I build a new plane with faster stronger servos, I will use the left over servos from a previously decommisionned plane as my throttle servo.
Although this has served me well, I have some concern now, as servo get faster and faster, if too fast a servo is not good for the carb. I am not too concern about torque as long as my set up is bind free and travel limited to the carb range. 1) What do you think? 2) What is a good servo for throttle? |

Faster won't be a problem at all, even if you move the servo very fast the carb yet needs to feed the engine so it's up to the carb.
As for the right servo, I rather have it with heat sink and metal gear, that way with all the vibs and heat it won't fail. My method is always to use the same servo I'm using on my surfaces. |

What makes the Hitec so special compared to others?

Again, I've experienced it when at idle, but never at anything above idle and only on a single. |

That is what I had in mind when talking about speed, seemed to me that this could happen.
So do we get to the point of slowing them down electronically or just be careful from idle to full tilt power? |

I understand that you had succes with them but so have I with my "hands me down" that I mentioned in my original post. I am looking for good reasons beside $$$ which always seem to be a motivator but not necessarily a good one in all cases.
Anecdotal evidence is not really what I am looking for, so please again |

there is no credible data that a higher dollar servo has a lower failure rate or is in any way more reliable than a less expensive servo. claims of "deadly accurate" have little merit as there is no direct comparison to anything else. throttle servos are a matter of faith. I have used many different servos for throttles on various sized airplanes and helicopters and have not found any reason to think that what you have been doing is going to be improved upon by spending more or buying new.

1) 180 degrees of travel (if desired) with full resolution (how many times have you setup five of six servos on your two ailerons only to find the last one does not have as much travel as the other five?, so now you have to start all over.) 2) Perfect linear out of the box (no other servos I've seen are) and that linearity remains no matter the amount of subtrim used (never seen a servo do that either). 3) No play, no gear slop, after 150 flights (I'll have to keep flying to see if I ever get any). 4) Immovable holding with very minimal power consumption. 5) Extremely accurate, I never experienced such accuracy with throttle trim on any other servo (I always use flagship servos on my throttle). 6) All this makes for the easiest to setup and use servo I know of. I'd just like everyone to try one/some. "Try it, you like it." haha |

Rcfly this is what I call a great answer with perhaps not scientific facts as you said but not a "I like it try it" type of answer.
This is the type of answer that makes me want to try a product with observation and qualities of the product at work. I will try the Hitec 9360 for sure. |
