I don't know which one of these to get. Its for a dual steering servo setup in the fg monster truck.
Here's the stats of each...

The hitec.....
Torque 4.8/6.0v : 208 / 250 oz. 15 / 18 kg.
Speed 4.8/6.0v : 0.18 / 0.15 second
Size : 2.3"x 1.1"x 2.0" 59 x 29 x 52mm
Weight : 5.68 oz. 161 g.


The futaba.......
Torque 4.8/6.0v : 233.2/291.5 oz.
Speed 4.8/6.0v : 0.29/0.23 second
Size 2.4 x 1.2 x 2.0 in
Weight 4.4 oz

Am I better off to Sacrifice speed over torque??

Thanks

A hitec 805BB.... it has more torque & speed than either one of those servos ..... costs less

805bb
Torque 4.8/6.0v .........275 / 343 oz. 19.8/24.7kg
Speed 4.8/6.0v.......... 0.19 / 0.14 second

@ 6.0V it has 343 oz torque and a speed of 0.14...non digital so no end set and only $35

SAVAGEJIM

For just bashing around, even the slower .23 sec transit speed is okay. For me, if I had my preference, I would take the Futaba one.

I personally use the Hitec 5745, actaully, I resorted two of them; I find the 250in-oz of only one unit lacking. That 500in-oz dames a world of difference when bashing. The wheels keep their position, and the 2 servos do not have any problems turning the massive 5th scale wheels at their full transit speed. I have had to tighten up the stiffness of the steering servo block by adding 2 O-rings (I have the alloy one), so that when going over bumps and stuff in a turn, the weels hold their position better.

I use digitals over non-digitals because my radio (a Futaba) transmits in HRS mode. In this transmission mode, I MUST use digital servos for everything, even the steering and braking servos.

Hellya has got it right!

SAVAGEJIM

Yeah, but if he is in the same situation that I am in, he would have to stick with digital servos. If that 805 were a 5805 or even what would be called a 7805 today, I would not hesitate buying one.

bigdeee

I won't buy the 805's because of the nylon gears. I decided to go with the 5745's got one in my fg stadium truck and it works great. Just wasn't sure if anything better had came out for the same price in the past 3 years.

hellya

I hear ya metal gears are good...I like the 700 oz torque I get [>:] Just rememeber to set the end stops or you can burn out the servos..... I'm sure your LHS can assit in that

they sell a nice programers for digital servos http://www.servocity.com/html/servo_...er_tester.html

Hellya, can't ya just set the end stops with radio ?

not that I'm aware of

Isnt that what the EPA on my computer radio does?

SAVAGEJIM

Yes, any Hitec digital servo can be programmed with the EPA controls on a programable radio set. The outside programmers are for radios not capable of using the digital features of digital radios.

Hellya, after working with my Jr radio, you can set the end stops with a radio, gues I already knew this (duh on my part), so you would not need to program the servo if your radio can do it for you using the EPA settings.. Think I'm going to try the servo you talked about above on my Baja..

If you want the best servo get a rhino digi4 initial 380ozin and .10sec transit, holding is 205ozin, some folk say you need a voltlimiter but as far as I'm aware my spektum 3000 only outputs 6v as does my nomadio transceiver so they wont burn out with no limiter. Maybe other receivers don't limit output voltage like the 2.4ghz ones

wan6176

im using hitec 5966 its 8sec speed

Wrong specs. the rihno id 200+ oz and 250 holding.[] The biggest cheapest servo is the GWS 777 with 470 oz for the price of 2 hs 805. If you want bigger than that a Tone 050 with a wapping 900 @ 6 volts.Orice of 2 hs 7545 seervos.

mooman007uk

wrong buddy, the rhino is actually 373 and not 380 (my mistake) initial and 205 holding...look it up, most other servos quote initial for their torque figures. The tonegawa is 600-1800 depending on input voltage but is as slow as a slug unless you get an oddified one. best servo after the rhino is the 5745. the gws 777 has plastic gears which for steering in 1/5 scale is akin to a chocolate fireguard.

Why do you keep lying about the specs???. I know for a fact that The rhino dosen't have 370? torque when I compare it to a HS 805. The Hs 805 beats it. Multiplex servo have good holding power that's it.[]

bsrman14

Her are the real number for the rhino servo www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXJCG2&P=ML - Cached
1. a servo cant have less holding power than starting torgue.
2. starting torque and holding power can be the same.
3 holding power is always more than startin torque.

Whatever dude, I guess all the things in your world run against the grain as can be seen in nearly all your posts. I think you need to do a bit more research before you mis-inform people
in metric the digi4 has listed 24.7kgcm initial and 18.9kgcm holding check the servo review in rcu

bsrman14

You should do a bit more research before you mis inform the people.
The true specs of the Digi4 are 205 oz starting torque and 380 oz holding power! Dislexic
I know this for a fact because I tried the Digi 4 and compared it to a hs 805. The hs 805 did the job whill the didgi 4 failed but could hold better.!!

bsrman14

I know for a fact that A hs 805 has more power than a Multiplex digi 4 hands dowm.

str8jailbird

I checked everywhere I could think of including Hitec RCD and Multiplex.N owhere can I find the Rhino listing The torque specs above 250oz. Here is the factory spec on the web.
http://www.multiplexusa.com/multiple...ino_digi_4.php

bsrman14

Exactly what I've been trying to say but ????. starting torque is only 205 oz.[]

Foxy

It may do, but the metal spline of the rhino means it can take hits better and will outlast the 805. Also, the 805 doesn't fit in all quarter scale servo sockets (think MCD for example). What you are saying is like saying that a Rock is better than a samurai sword because it's harder. Yes, a rock is harder, but the sword is a much more refined weapon and the preferable instrument. We've had this conversation before, so I doubt I'm gonna change your mind. I use both and that is my opinion. You are equally entitled to yours, oh and as for speed.... lol. Yeh...

Back on topic, the 5745 is again the superior servo.

As for specs, can't remember where I saw it to post a link, but I know that the holding power of the rhino is 24kg-cm, despite it's more measly 200oz-in initial torque, it is still more servo than you ever need in a 5th scale.

If Foxy endorses the 5745, then I'm glad I did purchase the 5745s. While out bashing in the cold a couple of days back, I am actually astonished at how responsive the 0.15 sec 60degree arc transit speed is to the turn of the radio wheel.

I use slower servos for my 8th scales, I have the 5995TG robot servos in my basher Savages, and those turn at 0.23sec transit speed, and they are actually significantly slower at the feel of the wheel. But I guess that is not all that bad, the slower transit speed does in some effect work like a de facto dual-rate steering, at least until the wheels hit a certain angles and the Savage tips over and rolls from the tangential velocity of the angular path of its supposed trajectory.

And as for flipping my gasser with 5745s? Oh yeah, I do that too easily. With the Futabas, I know my truck will have its wheels stick to the ground just a tad longer, at least until the angle of the wheels are such that my truck will roll over.
