overkill is a great thing!!!!!!!!!!

r/t

Sorry to hack this thread jatoman,I am still new to the hobby. just have a few questions concerning digital and analog servos.

1) Can I use digital servos with my spektrum dx3.0? Is it wise to get the digital servo eventhough I am not planning to race?
2) How can I make sure I do not overdrive or burn the servo faster than usual as posted by Timmah(post#9)?
3)I planning to get the airtronics 94358 or hitec 5955 if budget permits, any more recommendations for a lower price but still a good performing servo?

BTW, if it helps I will be running it on my hellfire.

Any input would be highly appreciated.

Thanks a lot Jatoman!

yes on the Digis and the Spektrum, just to sure to set up the end point adjustments so your not overstressing the servo trying to move it farther than the linkages allow it to.
Digis are great to use. very smooth and responsive, but arnt a needed thing, you ll prolly do just fine with analogs and save some green.

for 2. your radio has adjustments. one of them is called the EPA, or End Point adjustment. this tells the servo how far to move to either side. the bigger the EPA number the farther the servo turns. the smaller the number the less it turns. set it to Zero and your servo wont turn at all.


all i do is adjust the epas until the servo stops turning, then back it off until you see it move again, then add on or two digits higher.


both of those are nice servos, ive not used either, but hear many singing their praise.

I'm a big fan of the air 358 and have run it in a LSP and a t maxx racer for steering and throttle/brake with no issues at all, but I've heard of several folks having trouble with them in truggies. The primary complaint is breaking the one nylon gear in them and most people who have this problem replace that gear with a brass gear which takes care of the problem.

I've not had any digital HiTecs since they introduced them a few years back. Their original digitals (sorry, I don't remember the model number) had issues with an intermittent response lag as well as (again intermittent) problems with centering. After crashing my 8th buggy several times because it failed to turn when I told it to or wouldn't go back to center for a second or two after I told it to, I gave up on the HiTechs and bought a set of Air 358's which solved the problem. In fairness to HiTec, everyone I know running their current models are very pleased with them.

The ultra high refresh rate of digitals when compared to analogs is where most people get in trouble. You can overdrive an analog quite a bit for a short period with no problem, but the same amount of over travel on a digital for even a few seconds is enough to either kill it outright or over time as the excess heat breaks down the components on the control board. Analog servos also use much less power so you can go longer in a rec pack charge.

Unless you need the extra few tenths of a second or so per lap you (might) gain with digital servos, analogs will deliver more than enough power and speed to win, and are safer to use without having to worry about being a tiny bit off on your EPA.

thanks for all the input!I may just go with an analog servo since I am not really planning to race for a long time. I just want more steering torque.

Whichever servo you get, if you are going to be using the stock setup, get one of these.

If you are inclined you can get the same unit without holes and put it where you want it.
