Default How fast/torque is actually needed for off road buggy and truggy servos?

I have a question about servos. How much torque and speed do you actually need for an 8ight or a truggy? We are talking of fractions of a second that the average racer won't be able to notice. 300+ in oz of torque seems like over kill.

Or are these higher rated servos likely to last longer and take more abuse?

My personal preference for buggy is that I want my steering or throttle servo to have at least 120 oz/in of torque. I like my steering servo to be in the .12 range and my throttle to be at least .20. I've found that higher torque servos seem to last longer for me in both the throttle and steering position so I run airtronics 358s in both the throttle and steering spots. I also keep a JR650 for a back up throttle servo that I've used many times without issue before I put another 358 in the throttle.

the 650 is great for steering...

and i have used the futaba 9550 for the throttle...it has enough torque to slide all 4 on a XB8

bang for the buck...the 650 is hard to beat...

Default A servo is no place to get cheap.

I messed around with the setup on my MF2 for a long time, couldn't get the turn in like I wanted it. Picked up a 357 and it was like night and day. For steering get the most power/speed you can afford.

As for throttle control, don't ask me, but I'm sure it could be slower.

Yep, just get the fastest/torquiest you can afford. I run Airtronics 94358's on steering and throttle on my XB8, but something like the 94357 would be a bit better for throttle I figure. Throttle generally doesnt need as much torque if you have a good braking system. A faster throttle servo will let you get on the brakes right when you need to, or get on the throttle in a tight situation. If you have a high speed response radio you will need digital servos to take full advantage of the high speed response.

LOL...I just did an "8" with a 357 steering and a 359 (358 with a heatsink) throttle.

As one of the guys in another thread pointed out...as long as it has enough torque to push over the servo saver, it has enough to steer the buggy.

357s are not recommended by Airtronics for use in 1/8 buggies/truggies.

I'm loving my Ace Digital servos. #DS1313 for t/b and #DS1015 for steering.

for bang for your buck and reliability futaba is probably the way to go a digital s9451 is about 80.00 new its about 120.8/[email protected] 6.0 volts for throttle of course and s9351 on your steering 192.0/[email protected] 6.0 volts its about 115.00 new.i suggest futaba for two reasons yes you can buy ko propo servos but i ran them in my buggy and not only did i break the steering in a qual but when the throttle started to glitch if you use aluminum servo horns. but these are all a matter of prefrence as you will soon see prefrence and what you can afford. i can say one thing ko and futaba are great about fixxing anything and getting it back to you. ive never used airtronics or anyother brand because of price if i could afford them i would try the jr 9000s and 9000t these are a mean combo but very pricey

We race 1/8 mugens and I use a 94357 for throtle and a 94358 for steering used them all last year and never a problem. I like a little faster throttle servo that is why I use the 357 for it
94357 is 125 in/oz and .07
94358 is 200 in/oz and .10
good combo for 1/8 buggy if you ask me

How often do you think Drake puts new servos in his cars?

comparing what pro's run to us mere mortals isnt a fair judgement. alot of the top guys run 7.4 li po to an already 0.06 digital @6v, so imagine how fast that would be!! servo's are all a matter of personal expierience. i have had awful luck with jr's, hi-tec's, and the best w/airtronics. heard good things about ko's and futaba's and i will give them a try when i finally smoke all my airtronics. go with what your budget allows, but the more u spend now, the less you will spend later imho
