Default Suggested Torque for 1/8 buggy steering.

I was just looking for a "recomended" torque you guys aim for w/ your 8th scale buggies in competitive racing. I've always been a 1/10th scale electric racer, but now I am in the process of converting an RC8 to electric. Personally, I love the feel of Futaba's brushless servos in my 10th scales so I was planning on using one of those. Just no sure on which model.

As much torque as you can afford! 1/8 nitro obviously put a lot more strain on the whole steering, even electric converted there is more mass to crash. Personally i run the HiTec 5955TG - it's badged as a Robot Servo and has 330oz of Torque with titanium gears. It's not quite as fast as some others (By a shadow) but it's plenty fast enough. I got my first one second hand about 6 months ago and it has been rock solid through some serious track time and racing.

BTW, blue loktite the nut on the servo saver spring on the RC8 when you have found the right tension. It likes to loosen.


Hope this helps!

I use the same servo on my Cen Matrix TR Arena truggy. I had the 5955TG in my buggy but I switched it to a 5997TG now. I bought it fron Donald's Hobby for $89.99 with free shipping.

http://www.donalds-hobby.com/prod/sc...dproduct=42427

They maybe out of stock due to the new version of the 5955TG (the 7955TG) being released.

http://www.donalds-hobby.com/prod/Sc...dproduct=42635

Donald's Hobby still has the cheapest price I have found for the new 7955TG. If any of you find it cheaper please post it. Also Donald's hobby will price match.

I have to agree with this statement. I also run a 330 oz servo and can't imagine running anything else now on my race buggy. The Airtronics 358 was my former favorite and did the job very well but as the race day wore on and more and more of the track wound up inside my steering mechanism, the 358 would slow down a bit whereas the more powerful servo just powered through it.

You will be happy with a lower powered servo as it will work just fine, but if you can afford a more powerful servo you will definitely like it better. The only drawback is that is draws more juice from your receiver pack so you might have to recharge earlier.

JR 9000T for steeting
JR 9000S for throttle

(you would think the T is for thottle and S for steering... or maybe im the one mixed up?)

the 9000T has 300+ oz of torque
the 9000S reacting time is like .06 seconds at 6V

cant ask for anything better, and JR has the best warranty out there, 3 years hassle free.

The "T" is for Torque and the "S" is for Speed.

Thank you for all your replies, but maybe I should have rephrased it. How much torque is a recommended "minimum" for a competitive racer? I am looking at the futaba BLS452 which has 194 in/oz or the futaba BLS351 with 208 in/oz. Would these be sufficient?

I am running the ACE 1313 servo in my Kyosho. Awesome servo and cheaper than the above mentioned 5955TG. I have never ran the Hitec servo, but from what everyone says, I would have no issue with purchasing one they are bullit proof from what everyone says.

Plenty of torque for a buggy.

I'm running the Ace DS1015 servo in my TRUGGY which has larger tires and wheels. It's rated at 200oz but most claim it's more like 230ish.

I've got almost 3 gallons on the servo now without a whimper. If 200ish ounces is enough for a truggy it's plenty for a buggy.

I upgraded to a JR9100t for steering from a Hitec 130oz servo. I honestly can't tell a difference.

The strongest you can afford! I run the 5995TG in both Steering and Throttle. These two servos out lasted my Losi (Know servo eater), and now are in my 808. They both have over 40+ gallons (Closer to 50 now) on them, and still going strong. I have two other 5995TG as back ups still in ther box, that close to 2 years old waiting, to be used if needed...

5995TG = BOMB PROOF!!

Ive heard 180 - 200 is the minimum for steering

The cheapest servo youll ever own is the one you dont have to replace - not the one witht he lowest initial cost. In that regard, Ive heard pretty good things about JRs 9000s, 5955s and tehefutaba s9351a

you should also consider what radio you are running

Ihad a 5955 on steering and a 5965 on throttle on my RC8. I loved them when i was running a spektrum radio. But then I switched to the Futaba FASST and now none of my hitec or airtronics servos will center.
Hitec told me it wass becasue of the signal voltage and that they would replace the resistor in the hitec servo for free to male it read the signal voltage in the fasst system.
