Seem to having some problems with the Tamiya High Torque servo savers I have been using. They seem to wear out quite quickly and start to affect the steering.
Can anyone suggest a better option?

A lot of drivers seem to be fitting hi torque metal geared servos and going direct "no saver" via a weekish horn just in case,it gives a more positive feel to the steering.

Agree with that.
Adam is very pleased with Futaba S9551 Low Profile High Performance 45gm Digital Servo
Small size 40.5 x 21 x 25.4mm and 45gm weight.
Metal gears.
Speed 0.11sec. 8.8Kgm. at 6V
Replaced the S9550 servo
Although it goes through a servo saver, the saver is Soooo strong I cannot imagine it saving anything!

The Cyclone has the luxury of a in built adjustable saver that can be wound up really tight.
Im not a great lover of the servo fitting type,but a saver "of sorts" I feel is a must for the new driver.
A weak saver can be missed when trying to sort out a handling prob.( example:you cant get the car to turn in sharp from high speed then the car sudenly oversteers as it slows, even though trying all set up options advised)

Which Hi-Torque saver were you using Ian? Black or White. The Black ones are made of a weaker plastic and are no where near as strong as the white ones. I had a black one go on me at Broxtowe last year and i had only done bout 5 laps and not even hit anything lol.

I've got the white one and it's always had a bit of play in it, it seems to have slack around the centre, I put some diff grease on it and it helped it centre a little easier.

I have run both black and white versions. they both seem to end up doing the same. A small amount of play develops around the centre point and when "pushing" in a race sometimes the steering does not quite centralise. Not sure about not running a servo saver at all though. I am using the S9550 Futaba servo and not sure if that is metal geared or not.
As Les said it is one of those things you tend to take for granted and not check when you have a handling problem. Took me quite a while to discover it the first time it happened.
There must be something out there.

Ian try the Kimbro "not sure of spelling"..Lesro used to stock them,they have a tough return spring and the self centering is accurate. |

two options. The kimborough as previously recommended, otherwise Square make an alloy front plate to fit the tamiy high torque servo saver. Works very well to remove all the slop from the tamiya saver... Looks bling too  |

I had servo saver slop issues at WL this year, wasn't untill a very nice Mr Baldry spotted it some 4 hours into my troubleshooting of handling issues! - o how that little thing led me down the garden path! i followed Les's advice and connected with a "solid" horn rather than a saver at all!

Ed I have one of those on the 416. Seems to work fine.....just cannot remember where I got it from!
Might try one of the Kimbrough ones and see if it works though.

Matt has had "all due respect" quite a few hard bangs since WL, with no probs but he is direct to a real heavy duty servo.
Pop in an old servo and go direct one sunday or test day,or make up a horn and link rod and back to back it for a few laps, you might be surprised ,it does change the "feel" of the car.

On the TC I'm direct with a horn on a S9550 and the end result has been bent and snapped alloy turnbuckles! Now I've put titanium turnbuckles on, what's gonna break instead?
I notice Tamiya have announced an alloy front plate for their high-torque servo saver. The plastic one wears around the end of the metal rings, producing the play after a while.
I took the rings off the high torque one and put them around a kit M03 saver (which is just rubbish in it's standard form) and it works really well on the m03!

Now I've put titanium turnbuckles on, what's gonna break instead? ...would'nt like to guess on a Tamiya ;D..the purple one is very tough Ive been running direct for a long time without any probs,perhaps im lucky? |

The point of a servo saver is to save the servo afterall! Perhaps on TCs there's rarely enough force to break a high-end servo?
A different matter on offroad / heavy nitro cars etc though?
Though, I did manage to break a metal geared Hitec in an M03 just by not having my end points set correctly and overworking it. Much to Rob's bewilderment.

If Tamiya have made the alloy front plate then that is the way to go for me. Just have to find out where to get one from.
Might give a "no servo saver" a try and see if there is a noticable difference.

I ran no servo saver on my 415 for years, only ever had one issue where I caught the inside of a corner and strained the servo, thankfully was able to take it apart and give it a service, and it works fine in my M03 now. However, having seen the top TRF boys running the alloy front plate (from having been running solid horns), I figure if it's good enough for them, it's good enough for me Not had a single issue with it since swapping over, and still feels as direct with a horn (ooo errr!)  |

Hmm, ignore what I said, on the TC I seem to have a saver afterall, I obviously didn't pay that much attention. It might have saved the servo, but it didn't save my turnbuckles!
And it seems a bit weak, think I'll look at swapping that.
