Could someone tell me who makes the strongest (in a std size) servo ?
throttle and brake 1/4 scale car

thanks Kevin

hey kevin i'm running a hitec hs645mg i was shopping around too awhile back some said s9402 some said 94358/9 just depends how much you wanna spend you can buy three hitecs for the price of one airtronics good luck Brad

Thanks Brad I have been running the hitec servos and they work great,but i went to a 1/4 scale servo for the throttle and brake and had better luck but never have trouble with the hitec on steering .I would like to use a smaller one on my new WCM GN . Look in my gallery a pic of a clean way to mount it.
Where are you located ? Thanks Kevin

this is not my car but i just like the servo setup

These are pretty stout..........

I am running two HITEC 5955 for steering 333oz at 6v. and a HITEC 5998 for the throttle around 230oz @ 6 volts.

These are pretty stout..........

What type of receiver and setup is needed for the digital servos?

It's hard to beat Hitec's prices esp on the 645mg but be sure to buy backups as they tend to go out if abused and sometimes for no reason.

I am runnig a Futaba FASST system receiver with a 3PKS radio with a FASST transmitter module 2.4GHz. This is an awsome setup.

I did not look at this picture, but check out Knoxmotorsports for an awsome servo mount for the brake/throttle. This is what I am running.

I have the spektrum so I assume this will work as well?

Heck I'm so far behind in the electronics it ain't funny.

I'm still running PCM's in my boats

James

Spektrum works great. Thats what I was running before the Futaba.

Thanks,

I didn't know it came with the futaba 3pk as a package deal when I purchased my sprint

hey kevin i'm in california i run a sprinter the hs645mg is a standard size servo. i'm assuming you're running a wcm car you need to get ahold of robert knox he is a wcm dealer and has all kinds of trick parts for them check him out he is knoxmotorsports.com Brad

screw spectrum i'm sticking to my xl2p hahahahaha

what would be nice is if someone would come up with a steering setup for the WCM to use a 1/4 scale servo. Something like the raco used.....

James

i'm telling you guys talk to robert knox he can make that servo set-up possible it would be Very easy just relace that 2 servo plate with asimilar one to hold one big one... knoxmotorsports.com

I run a 3PK with no problems.....I don't know how you can run a 645 servo. We cant do that here, we have to have high torque.

you might need a higher torque for the gn cars since you have wider tires and more downforce. the 645 has like 125oz at 6v x2 thats a fair amount of torque...

The HS 645MG has 133 ozs torque @ 6v Remember we didn't have these high torque servos back 10 yrs ago and did just fine with 100oz servos in the GN cars. The strain on them was dead weight not rolling once you got one rolling they worked fine. The thing is servo savers aren't strong enough still at dead weight if you use the hige end servos and with the car static turn the wheels and you'll see the servo savers giving more than the tires are turning.

yeah what he said!! :wave:

Airtronics 94538 200 oz are what I use The HS 5955 are good to , yes the cost ,but in the long run and performance gain is worth the money ,
I was working all week on my car trying to figure out why the setup wasnt working ,I was running the same set up as the faster guys where. But my car would not turn like there cars could ,had to be very careful going in ,I was running hs 645 that was the only difference , I just could not bring myself to spend the extra money for the 200oz servos. One of the guys keep telling me you need the better servos & I kept saying YEA ! YEA!
But never changed and had a terrible [2006] race season ,Almost said to heck with it and quit , At the end of season .Well my wife heard my freind about the servos ,And bought me the Airtronics 94358s I put them in the new car . I just coul;d not belive the difference it was all i needed ,, Wont go back after seeing what the gain is ,I think the biggest thing is when going thru the turns you scrub alot of speed whit the lighter weight servos [ my reason they only turn when the car is moving so you go in with a delayed turning time and have to have a bunch of dual rate] as with the better servos you can put your foot on top of a setting car and turn the wheels and they turn , So the wheels turn when you want them to no delayed time This is what i seen and getting them new servos was one of the best things that i did for my racing , In season point 2006 i came in 9th out of 10 ,2007 i came in 2nd out 13 , following the freind that told me to go to at least 200oz servos

Nah, I run same widths regardless of class. But on our track there is so much speed and downforce in the corners it is needed to have high torque servos.

I use the JR 8611A for both steering and throtle/brake, they are 330 OZ at 6v and are STD size!!!!...

Hey Robert would you be interested in building a servo setup fort he wcm using only 1 1/4 scale servo?

James

Would this be for the steering or the throttle ,,, Robert

Forget the one servo deal on steering. It will not work. Servo may have the umph you need but the single servo saver will let you down. Have seen guys try this before and all had the same results, snapped servo saver or servo output shaft and end results was a damaged race car.

Yes I agree one servo saver wont be enough ,, Robert

You would have to redesign the entire layout of the steering system so that it would not use a kimbrough servo saver but another form of servo saver like used on the racos. Those worked really nice and didn't come apart or get weak and I never broke a servo in one either.

James

Iam putting together a new WCM K1E gn car For a friend , And i had a problem with a new y connector, only one servo was working , I could compress the chassis down by hand and the[one] steering servo would still turn the tires, That is one powerful servo ,,, He gave me two HS 5955 tg to install for the steerng , Just thought i would share that with you ,... Robert

Yeah Bob, they have much more torque than those Airtronics for less the money....133ozs. more. :thumbsup:

Dave - Do you know the 4.8 specs on these servos?

The Hobbico CS-170 has 333 oz torg at 6v.Has any one use this servo before?If so do you recommend useing it?They are $88.00 each.

Dave - Do you know the 4.8 specs on these servos?

I am not sure but I will try to find out for you!!!...
I found it, 4.8V 240 in/oz
I hope this helps!!!...

Though not this particular servo, I do use a Hobbico servo for my throttle/brake & have had success with them. The Hobbico CS-170 has 333 oz torg at 6v.Has any one use this servo before?If so do you recommend useing it?They are $88.00 each.
