Just wanted to give a quick review on the Savox 1230SG servo I used to replace my stock dual steering setup that burnt out on me.
The Savox 1230SG, 500 oz-in of torque at 6V, so far is performing AMAZINGLY!! Spent about 2.5 hours yesterday rock crawling and bashing on it for the first time and the difference between it and the stock Traxxas 2075 servos is VERY noticeable. Now I did also install a CC BEC at the same time because I wanted to make sure I got the 6V of power to the servo so I could take full advantage of the 500 oz-in of torque so the servo is definately not lacking for power.
Turning on pavement is sharp and crisp. Turning radius has definitely decreased. Turning on dirt is just as good as I can really whip the rear end of the truck around now when doing a 180 degree turn. Reminds me a little now of my Slash 4x4...but not quite to that level of control of course. Rock crawling is where I really saw the difference as I was able to really crank the wheels over obstacles and angles I just wasn't able to before. Before I would have to reverse to get the 2075 servos a chance to release and reload to yank the wheels over. The Savox just doesn't have that issue. On tight angles where the wheels are pinned between rocks the wheels will start to trun the direction I want. Not fully as I still have all the stock steering linkage installed to the Savox and the stock linkage is a little soft (I haven't done the washer mod either yet), but I don't have to back up to get them to start to yank over and that is a really nice difference. Power is not lacking. Also the steel gears hopefully will hold up well, only time will tell.Servo stayed cool even with all the abuse it took yesterday, and that is even with a thick coat of Pastidip on it for waterproofing. Installation was also a breeze as its a 25 spline so it just drops in and mounts up to the stock Summit servo horn.
There are a few cons that I have identified. Of course its not waterproof so I had to do that myself. Not a big deal if you don't mind doing that sort of thing. I just sprayed it with 3 coats of Plastidip and that should do the trick on keeping water out. I noticed the servo does also make a fair bit of noise. It is digital so it makes a fair bit of a "crackling" sound, which will change over to a hummm for a bit when it centers, then goes quiet for a while depending on pressure on the front wheels. Then will start over again. Occilates between cracking to silent to humming. Not a big deal to me as I am used to my other digital servos doing this from time to time, but if you are looking for a silent servo this is not it.
So over all I am VERY HAPPY with the purchase. I went to the hobby store to get a Hitec Titanium servo but just couldn't justify the Hitec price on my limited budget. The Savox was $74 at my LHS and the Hitec servos they had that were faily comprable on specs were $120 and $190 respectively. So I decided to give Savox a try and I have been very happy. Im not bashing on Hitec in anyway I have owned their servos before on other cars I have had and they have been perfect, but when on a budget and my stock steering went out on me, I am glad so far I gave Savox a try.
My next move will be to shop around for the best aluminum steering arms and or maybe just do the washer mod to the servo saver to tighten up the rest of the steering system. Other wise I am very happy with the Savox single servo steering setup on my Summit.
I will try and update my experiences with this servo as I go long term with it. Trust me with the amount of time I spend driving the Summit it will be tested over and over again.
