Choosing a Hitec HS-7955TG for steering and HS-985MG for throttle/brake on an 8ight 2.0 rtr. I don't think there is no reason for not choosing the 7955 other than a possible overkill, but do we want to take chances. And I seen on here that the Hitec representative recommended the 985 for throttle brake b/c it has decent speed, good torque and is analog. There was something mentioned about not using digital on T/B servos.

So without needing a recommendation of other brands, is there any reason to switch up my Hitec choices for one of their other servos. And don't want to go any higher on prices and not running lipo receiver pack. Thanks in advance.

It doesn't make much sense, to me, not to use digital servos for throttle/brake functions. I'd be really interested to hear why. Digital servos produce more speed, holding strength, and torque all across their range of travel, while analog servos do not.

Regardless, there is nothing wrong with some overkill. Many times it's a no brainer to just go ahead and stick the strongest servo you can into a model. Usuaully, the most torquey servos also offer the best speed, and at a minimal price increase over the next model down.

I just picked up a couple Futaba S9157 servos for my Losi 8ight. To me, it made more sense then the next best servo below the 9157. For an additional $10, I got almost 100 ounces of torque more, and more speed. Servos, like all electronics are an investment. If you sell a model, chances are you'll hang onto the electronics and use it in another.

"Analog servos are great for throttle applications in 1/8th scale. The throttle linkage has to be absolutely perfect for digital servos, where an analog can handle being just a little off and not be affected too much. Digital servos have precise centering characteristics and better holding torque which make it ideal for steering but a little difiicult for throttle applications. I hope this helps in your decision."

Wasn't sure how to quote from another thread, and for a loss of time, just did a copy/paste, but Billy T w/ Hitec said the above.

I guess that what he was getting at was that analog are a little more forgiving in setting up a throttle/brake linkage. Since I have taken the time in the past to set up my gaps and epa's properly then I should be ok with a digital. Thanks Espeefan for making me take a second look.

In this day and age, with the higher end computer radios, set-up is a non-issue. EPA and subtrim will make it possible to dial in a perfect throttle/brake linkage set-up everytime.

I agree that I'll be able to dial it in. That post from the hitec rep was just last month though, so maybe he was directing it towards a rookie driver????

I've been told repeatedly to avoid digital servos for throttle because of centering issues. They prefer to center themselves perfectly at rest but there's no such thing as rest on a throttle servo with the constant blipping. They keep buzzing and trying but never quite find center before they're off again. They're awesome for steering though.
