I love ACE servo's performance , but have had nothing but reliability issues with them.....I think they perform better then the Hitech servo's, but they are nowhere near as durable... We had to drop out of quite a few races due to the ACE servos failing, now as much as I like how they perform I will not use them.... too bad as I do really like them...

Agreed do not buy used, these are a key part of your vehicle.

Hitec 7954 you can run the un-regulated lipo or standard hump pack have gobs of torque even off lipo and are pretty damn quick. I run them for both throttle and steering. You can't beat Hitec for reliability and even if they fail Hitec customer service is top notch. You can find them on ebay for around 85 bucks brand new!

I do the exact opposite. 7940 on throttle and 7950 for steering. Hitec servos can't be beat. So a little eBay search and they are only about $20 more than the 7955. But the 7955's all around works well too. I seem to like a faster .12-.10sec servo on the throttle. Just my personal preference.

Default Well

To answer your question the steering servo needs more than 150oz in torque and speed depends on the driver. I like faster servos at .10-.14 transit time, but a bit slower shouldn't hurt, but torque is the most important in a steering servo and remember that endpoints arent the only thing that can cause problems in a steering servo, the servo saver needs a bit of room on the spring to relieve the servo during a crash, Locking down the spring is just asking for trouble.

The throttle servo needs at least 100oz of torque to stop the car well, and I do feel speed is important in a throttle servo around .14-.10 transit time. I find the throttle servo can be less than the steering servo, but in my car I use Ace DS1313 servos for steering so if something happens to it it's only 80 bucks to replace, and I've had good luck with those servos in buggy, but in the throttle I like the Futaba bls451. It's brushless and is really smooth and fast and the gears on those new futaba servos are so nice and being in the throttle that futaba won't get torn up being in the throttle, just make sure you don't make the servo push the brakes harder than the brakes can go, if you adjust the brakes properly you won't need to cram the servo too hard anyway.

Now keep in mind there are other good servos, those two brands are my favorite though....

I agree with the others. This is one area where you should not go cheap. Any of the servos listed above are good, I am sure. I personally use a JR9100T on steering and a JR4800T on throttle in my Losi Eight. The 9100 is over 2 years old, and the 4800 is over 4 years old and used to be a steering servo in a tenth scale truck. No issues on either one.

Make sure your steering endpoints and brake/throttle linkages are set right, and there's no reason any of the servos listed won't give you years of performance.

So what would you guy recomend for someone that is unemployed and a full time student that has 125.00 to spend on a good radio/reciver and a steering servo for my Ofna MBX buggy? I know the responce is going to be wait and buy better but this is my budget and i cant spend anymore than that. (the wife says so, if i spend more i have to sell off the buggy)

Sorry dude, but if you want to spend $125 on a new radio/receiver and servo combined, you will not anything "good".

There is a good reason why you should just wait... If you get a runaway with cheap electronics, you will be destroying a ton of expensive stuff.

Ive already had a run away the 2nd day of owning it on the 3rd tank, the am radio blows, ANYTHING is better than what i have now. Ive found a jr servo thats around 160 oz of tq that would leave me 75.00 to buy a cheap FM radio/reciver. It can be done, trying to drive this car with 60 oz servos and a AM radio sucks.

Hell this radio is 20.00 hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=10608 that would leave me with 100.00 for a good servo, and its better than what i have now right?!?!?

The Airtronics mx3fg 2.4 is around 150. It's a great radio. and the ace1313 is 75 bucks. A little more than you budget, but get the radio now and the servo later. Watch out for cheap radios from off brands. They don't have endpoints usually. The two best brands with the most history and reliability are Airtronics and Futaba. I think Airtronics makes a sport 2.4 that is like 100 bucks.

How about a hitech 985 for throttle on a buggy. I have a new 7955 for steering but have not found a servo I want for throttle.

Has anyone had any experience with Hitec's High
voltage servos such as the HS-7954SH?
at 6.0 volts its torque and speed is the same as the HS-7955TG
that most people recommend, however it will handle 7.4 volts
and this increases the torque to 403 oz/in and speed to .12 sec.
what are the advantages of the titanium gears of the 7955 as opposed
to the metal gears of the 7954?

He means this one: http://www.amainhobbies.com/product_...annel-Receiver

$100 for a 2.4 ghz system. You can add another receiver later, but it is about $70 (then you could drive your Mini-T with the good radio too!) I haven't driven with this radio, so I don't know how responsive it is...

Of course spending $100 on the radio only leaves you $25 to spend on a servo... and a $25 servo is junk.
