what kind of a servo?

http://www.rc-freunde-schwarzwald.de/TB2/DSCI0271.jpg

I'm looking for an aluminum servo lever but do not know what that might fit.

Plastic lever of my jumbo Futaba S 3302 servos fit in these servo.

also servo lever of this Servo fits too

http://cgi.ebay.de/2-x-Power-Servo-Metallgetriebe-15-KG-NEU-High-Speed_W0QQitemZ320453542038QQcmdZViewItemQQptZRC_M odellbau?hash=item4a9c850096

has anybody idea what is fitting?

MPX, Robbe, Futaba, Graupner?

[RCKIWI]

Nutech make alloy horn P/No: 059619 but not sure what other brand would fit.

[Chicony-Tuning]

thx a lot.

but this is the same like the plastic lever.

it is only 3 holes....and this is to short.

it musst be 1 hole more.

the problem is i must make steering on radio always on 100% but steering in Car is only maximum 85%

but i think for this time i wil try now.

[46u]

On my Rhino Digi 4 I am running one of the servo horns that came with my HPI 5b SS kit and it is about one hole longer then the stock horn. If it was any longer the linkage would hit the chassis brace.

[stevo1969]

these fit, they are on ebay and also fit sanwa.

[Chicony-Tuning]

I,ve a big Prob. with this Servo.

Today after 5 Min. the Servo died......

When I wanted to drive the servo scored an easy spray and that was the end of the servo.

[dc2 man]

listen I'm not trying to be smart here and i don't mean offend to anybody.

BUT.....

any large scale car user knows that all servos from the asian side of the planet aren't the best (no offence nutech) this is common knowledge.

you should know that nutech shouldn't even have to supply servos as there prices are already awesome but they supply these anyway like Carson servos but everybody knows that they need to be replaced immediately.

if you have any experience with large scale cars you should have known that you need a hitec 5745 hitec or multiplex rhino in there.

i don't mean any smartness to anybody just calling it as it is.

but it was good of you to test servo anyway.

when i got my cason c5 i was surprised how long the stock servos held up i managed a gallon :excited:

For 1/4 scale servos, I use either the Multiplex Rhino DIGI4 or the Hitec 5745.
Both work well and both are digital.

For 1/4 scale servos, I use either the Multiplex Rhino DIGI4 or the Hitec 5745.
Both work well and both are digital.
Is there a mechanical difference between the 2 other than the output splines? Torque and transit time seem to be different every where I see a comparison done.
HiTec

250ozin transit time .15sec
Multiplex Rhino

250 ozin transit time .10sec
another one with conflicting info.
http://www.servodatabase.com/servo/multiplex/rhino-digi-4
354@4.8v transit time of .10sec

Krap I don't know what to believe.

How do they compare in the real world?

[mooman007uk]

I've been thru this one before on a couple of forums and ended up contacting multiplex in Germany for the specs on the digi4..
digi4 has 24kg torque which is 383ozin or thereabouts and .10 transit to 40degrees which is .14 to 60 with 6v
The explanation I received was that the initial torque is 383 but holding torque is 250 and the Germans being conservative and totally honest list it at holding torque...nearly every other manufacturer list it at initial to inflate the figures...hats off to mplex for being real world

I have both and put side by side to test these and the rhino is waaaay more powerful and quicker than the 5745..it's the best 1/4 scale servo out there (not including the harm modified digi4 that is has insane figures but costs 3 times more or the oddified tonegawa which IS the most powerful servo you can throw in a 1/5 scale with 1000ozin and much more with added voltage.. 1600 with 9.6 lipos i believe and transit of .12...ask foxy he has one...they are slow stock but Ian Oddy souped them up to have fast transit times of i believe .18 to 60 at 6v)
also the digi4, as clubin mentioned, has the bigger splines and also beefier bearings...i've had mine now for over 2 years and it's as good as new the 5745 has smaller bearings and when used for steering get sloppy after a while...the dig4 is near twice the price of the 5745 but 5 times the servo

I know that the stock servos usually any good, and nothing that I should share it right away.
But I am writing here in Germany, a report on the state of the standard system Nutech.
That is, what are the advantages of this car out of the box and disadvantages.
And I can say that in Germany there are enough people who go to exchange these servos every 2 days.
That means every dealer sells a Nutech and given away to 5 servos for people to get themselves on it, exchange the against a better one.n.

[mooman007uk]

I have suggested to Chris that maybe the steering servo used on the 5b would be a good one to use if he can source them there...I belive they are made in Taiwan which is part of China...the hpi one with metal gears and lots of torque is a good servo and many by them as an aftermarket hop up for other models

[Chicony-Tuning]

The Hitec 805MG is a good Servo to....and about 45€ in Germany ist a cheap price.

I am not a fan of the 805, I ruined lots of them in my FG. From sheared output shafts to busted up plastic gears. It can not handle the impact of a crash. It would be awsome if there was a metal gear conversion for them though, because they are relatively fast and very powerful.

I do love the HiTec 5745, I haven't done anything to break one yet.

[Chicony-Tuning]

So now I have the Hitec HS 5745 times compared with the HS 805MG

i think you mean the HS 805BB+

here i post you an Topic out of my Forum


There is a metal gear for the Hitec HS-805BB servos jumbo.

Many are looking for a good steering servo which is not all too expensive and it brings good benefits.

The Hitec HS-805 is one of them

http://www.mhm-modellbau.de/bilder/112805.jpg

It will now cost around 30 €

Here are the data of the servo


Specifications:
Operating Voltage: 4,8-6,0 V;
Torque / Torque 4.8 / 6V (Ncm) 198/247 19.8 kg kg/24.7
Operating speed: 0.19 / 0.14 s/60 °;
Dimensions: 66x30x58 mm;
Weight: 152.0 g

The financial data relate to 4.8 / 6.0 V operating voltage!

Description:
The current analog servo probably the strongest in the field! With a generously proportioned, hardened gears and drive shafts, resists the HS-805 also strongly stresses.

Features: 6-fold Poti, double ball bearings, plastic gears

Application:
Powered flight models up to 25 kg, 1:4 to 1:6 cars, power boats up to 2,000 mm

Well, you have this option as an "upgrade" or alternatively a "Metal Gear"

Hitec SKU: 56,410
Multiplex Model: 11 9045

You can get this at

http://www.ams.ch/shopgeams/servos/hitec/zahnradsatz-hitec-805bb-und-805mg.html
Alternatively, you can also buy just the Hitec HS-805MG.

HS-805MG

The 805MG is identical in construction of size and performance as the 805BB but has a metal gear!

and what is most important, the main gear is made of aluminum! The Servoaluhebel from Rhino Digi4 not fit (included)! Thus broken gears are a thing of the past!

And i run the HS 805BB+ now one Year in my CF...and have no Probs with it

[Clubin]

805bb is still plastic gears correct? With a plastic output spline? I am sure the ones I have rebuilt are 805bb's? I thought so anyway, could be wrong. The rebuild kit is worth 11.00 canadian, and the whole servo is worth 35.00 Canadian. THese are the ones I bought. http://www.greathobbies.com/productinfo/?prod_id=HITHS805BS

[raybkk]

Well, NuTech wants to stand out with a top product. So if they want to call the product RTR they should provide durable servo's should they want to reach their goal in building good cars. If not than just call it RTB. When those RTR cars end up at the shelves in big shops and 80% of the customers walk back in with broken Servo's after the 1st of purchase it wont do the brand no good.

[dc2 man]

look my opinion the 5745 is the best all rounder it has enough power,its not hitting the pocket too hard and its damm relibale...

i have a 3year old one now with maybe 20gallons in an fg evo and its perfect!

i woult suggest (i have too done this) is to modify it to fit in chassis,any servo can be fitted with simple mods to area and chassis.i modified my fg beetle to house 2 large hitecs one for steering and one large also all METAL GEARED for throttle too.

cheap servos are only a joke and those small hitecs are good for nothing really......they burn up with any sign of stress

[46u]

I really like the Rhino Digi 4 in my HPI 5b SS and only time with tell how I like it in my TBII PR. I found out a LONG time ago cheap servos do not cut it.

[Chicony-Tuning]

I,ve a big Prob. with this Servo.

Today after 5 Min. the Servo died......

When I wanted to drive the servo scored an easy spray and that was the end of the servo.

Today i´ve looking whats happen with the stock Servo...it is water in it or damage.

since the same time i open it....two microships falls out :surprise:

This microships were apparently not soldered to the board, but apparently only glued :dots:

[dc2 man]

OMG what were they doing with little ships in the servos,and more importantly how did they get them in there:surprise:

unless you meant little microchips LOLLOL

[bens_rc]

My servo went up in smokeand nearly burnt the car to the ground :surprise:. I think it is the same 2 chips that cause the problems

http://www.bensrc.com/HSP/DSC01878.JPG

[Clubin]

Those 2 chips are probaly heat sinks.

[Chicony-Tuning]

OMG what were they doing with little ships in the servos,and more importantly how did they get them in there:surprise:

unless you meant little microchips LOLLOL

LOL yes i mean microchips LOL

tomorrow i make a picture

[dc2 man]

good to see you saw the funny side chicony... ;)

its actually very intresting to see somebody discussing these servos and testing them out,man it would be great if nutech could come up with a decent servo at a decent price.

im tired of paying through the nose to european manufactures for servos.

Nutech does listen to it's customers....So you just never know. ;)

[dc2 man]

yes mradlin good point bud.....:good idea:
