S3302 servo
[
]After running my firehammer with 2 tanks of fuel,and not being to hard on it,just a couple of rolls and some very small air the steering wouldn't work anymore.The s3302 servo just sitting makes a sort of chattering sound.I took the radio tray out and removed the horn from the servo,turned the power back on and the servo now turns left and right with the same chattering noise,and I am able to hold the output shaft from turning with just 2 fingers.My questions are:is this servo to weak for offroad?Is the stock servo saver spring to strong?(It feels awful heavy)Has this happened to anyone else?[&o][]

RE: S3302 servo
Well, it's safe to say that the servo is cashed. BUT that servo is more than strong enough for the Firehammer.
I'm guessign the servo saver was set too tight. Or something like a rock or stick got in the linkage and bound it all up causing a gear tooth to chip off.
Breaking servos on off roaders is to be an expected thing. It happens on occasion, nothing much we can do about it expect pray for the best.
Is the servo saver adjustable, like with a nut or something? If so, loosen it up a notch.
I run the same servo in my Sportsline and have had zero problems, but then again it's not hitting bumps or ruts either.

RE: S3302 servo
Thanks guy I checked the setting on the servo saver and it doesn't look to be adjustable.It just seems to be awful heavy.This time it is covered under warrantybut next time[&o]Does anyone make an adjustable servo saver for the hammer?At $50 bucks one can't afford to be replacing it every time it takes a roll[sm=cool.gif][sm=tongue.gif]

RE: S3302 servo
you could of just stripped the teeth off one of the gears,i have stripped a few just open them up and replace the one you need - if its a metal geared servo its normally the first gear that strips (made of resin/sacrificial gear) - normally couple $ ea if it cant be replaced under warrenty

RE: S3302 servo
or you could replae the servo horn with a alloy horn with plastic inserts that way the insert will fail as well ... i use that setup with my 5745 MG servo ...

RE: S3302 servo
yeh the horns that use the plastic multi spine inserts are naff,they strip under very little load,the hitecs servos i bought the alloy horns came as standard,the futaba ones had to be bought as an upgrade.

Yep, ditch the chepo servo and step up to all metal gear driven servo like this, I have these in both of my hammers ,and I will never go back

RE: S3302 servo
I still run the stock S3302 steering servo. It has metal gears and as RC Mad pointed out there is one intentional weak link. The servo does not have outstanding specs but it does seem to work pretty well.
I have beat the crap out of my Firehammer over the last year. It was probably six months old when I bought it used. I have broken 4 or 5 knuckle arms as well. Never had a moments trouble from the S3302 servo.
I did have the steering rate knob turned down once and thought the servo was going out because it would hardly turn. Once I turned the rate back up to full the steering is responsive.
You probably just have a factory-defective servo. The replacement unit *should* stand up well (assuming it is not defective also).
If you want or need to replace the steering servo the Hitec HS-805BB is highly recommended on this forum and can be had for around $40:
http://www2.towerhobbies.com/cgi-bin...&I=LXN610&P=ML
Supposedly the Hobbico CS-80 servo is the Hitec HS-805BB with the Hobbico name on it for $30:
http://www2.towerhobbies.com/cgi-bin...?&I=LXLN93&P=7
Both of those servos include a Y-cable to allow you to run the servo power directly from the battery (6 volts) instead of running through the receiver power (regulated down to 4.8 volts) giving you a boost in steering torque. This Y-cable can cost $5 - $10 separately.

Metals gears in the stock servo??? There is only 1 metal gear, the final gear that the horn goes on, the rest are plastic, and they strip pretty easy. and these also have BB also

Hi Matt,do you use a Y harness with this servo as is reccomended with the Hi-tech 805BB and the Hobbico CS-80 also recomended in this thread?

RE: S3302 servo
Hi Ken,these 2 servos do they have all metal gears also,like the futaba S5301? I don't see it mentioned in the listing as it is with the futaba listing.I like the hobbico price compared to the $80 futaba

RE: S3302 servo
I stand corrected. I thought it had more metal gears but it is just the final gear/horn.
With that said I have a lot of hard driving runtime on that S3302 servo and it has not let me down in over a year of bashing. I would like to upgrade to the HS-805BB or CS-80 but unless the stock servo dies other hardening upgrades take the front seat.
The Hitec HS-805BB and the Hobbico CS-80 both have 'resin' plastic gears throughout. That does not seem to be a weakness for these servos. Several forum members who have run these for a few years swear by them. And for $30 - $40 USD if you wear one out, it doesn't hurt financially to replace them.
Others here who have bought the Hitec digital quarter-scale servo (5745?) for steering have been frustrated with servos getting burned up. Hitec has great customer service but it might not be worth the expense and aggrivation to go with a digital steering servo.

RE: S3302 servo
No, I do use a Y-harness. I use the same setup that comes with the car, and no problems. Just striping the plastic gears . So I upgraded too all metal gear drive in both cars

RE: S3302 servo
Elcon has come out with an easily adjustable servo saver.
It should fit on the Firehammer also, but.....
Maybe someone here has tried it on a Firehammer, Carson Attack or one of the other clones.

RE: S3302 servo
What makes the Elcon servo saver better than the FG 4494 saver (the one with bearings)? I would think the bearings would make the servo saver work more efficiently.
Does the Elcon have bearings also?

RE: S3302 servo
i have had the fg alloy one (not the bearing type) and you always get slack/play on one side of the saver - its never equal no matter how much you adjust the fg alloy or stock saver,i bought the elcon one a few weeks ago & theres no play on the saver it centres no problem + its adjustable,they extra springs for people running tone servos

RE: S3302 servo
The Elcon does not have ball bearings, as far as I can see.
The advantage is that it is more easily adjustable. Just turn a nut..
It also comes standard with 2 different springs, and if needed, one should easily be able to find other springs that can be used.
Also, there is no O-Rings that can be worn down or break.

RE: S3302 servo
the elcon savers are in another league. get one you wont regret it, i use the strong spring shimmed up 5mm and aint bust a servo in 5 rounds of racing.
