I run savox servo's in mine with a 1800 mah protek life battery with the use of heavy dif oils and power without enough torque the steering will straighten out when you get on the gas

I see alot are having success going to higher and higher torque servo's especially on the steering.

With the relatively high weight of the GT8 Nitro cars and drivers pushing them harder and harder I can see why, but where will it top out?
How much torque is enough?
Evo13 felt better responce from his car with a 472oz torque servo!!
Sounds extreme ..... but it works.

I figured 200 - 250oz for steering should be enough. But now not so sure.

Thanks everyone for the reply's. Seams alot have found going to high voltage is the way to go. My M11 with FHSS-2 just doesn't support that. :-(
Could feasably go to a LIFE battery?

Rgards,
BM
I ran lipo's, played with life batteries. Either way you can't go wrong. I like to see 300oz+ for my steering, 200oz-250oz works though. Even better is 400oz! I can definitely see a difference on how the car behaves. These are big, heavy, fast cars; they can use all the help they can get. Gotta have fast too! Around .10 for steering, and at least that or prefer to be single digit speed for throttle/brake.

I really like the new Signature Series RadioPost, too.

They were out of stock when i ordered my 4 Greens. Only reason I'm not running them.

Thats a good question. I know a couple of people who have used the older Radiopost servo's, me included and I have had good use from them.
I used them on a 1/5th scale car!

Not too sure how long these have been out, not all that long I don't think.

I'm thinking of getting one for the steering on my car and using the Red "Torque" Radiopost for throttle/Brake.

Will see how they both fair in practice.

I was very interested in the Protek Servo's untill Tony L pointed me in the Radiopost direction. Protek seamed to have sparked off a rejuvination (forgive the spelling ) in servo's and their "usual" specs.

Alot of servo's now are very impressive in the specs when compared to just a few years ago!!

Regards,
BM

Another great choice are the RSX servos from KO.

Is there such a thing as overkill when buying servos?
say for example, if I get the radio post Black for a 1/8?(throttle and steering) 400 tq.

I had to add some additional support with the high torque servos in the DM1, with stand up servo mount. Was able to flex 2.25mm carbon fiber.

I was thinking the same thing, when shopping for my new cars. Unfortunately they were out of stock of Sig so opted for the Green, which I have used for the last 3 yrs with no issue.

But did contemplate, is there ever to much torque? I think with that kind of power your liable to turn stuff up on the car. Or strip gears in servo. But wont know till you try.

All the servo’s mentioned are worthy of doing the job, for me Futaba is the manufacturer that I look to for my RC electronics. Futaba has been in the RC game a very long time & is imo what many use as the industry standard.


I have been using Futaba BLS157HV servo’s in my Xray GT8 for 3 seasons without any form of a glitch with a 7.4v, 2500mAh, Li-Po battery.

Here are the stats….



I recently built another GT8 & the BLS157HV have been replaced by these BLS172SV. They are incredible I doubt I will change any time soon.

Here are the stats….



Just a FYI those stats for .11ms for speed are modest I promise you. These servo’s BLAZE… & 514 for torque is beautiful thing

Just remember these are HV servo's use a Li-Po

Thanks 1Speedy for the post....
Yet another indication that using servo's on these cars with torque over and above 350oz seams to work.
I think with the weight of the cars, ever increasing speeds. Not only on the straights but more relevant, faster around the corners put more demands on the servo's we are using.

I agree with 1Speedy in that for as long as I can remember, Futaba have been the goto for quality. The "go-to" manufacturer.

BM
