Standard Servo Saver

[piepie31]

Hi fellow 3 speeders could anyone tell me if the standard servo saver is upto the job with a high torque servo :Tamiya1:

[Pete359]

No need for a servosaver with high torque servo.

[piepie31]

Hmmm not sure Pete I think I'd prefer to have something in place just to protect it

[Pete359]

The high torque servo will just tear it apart :sorry:

[william]

the ofna high torque servo saver designed for gas/nitro cars is a good choice for a high torque metal gear servo

[Mouton]

Pete359 is actually correct. If you have a car that you race hard around a track or jump a lot then you naturally need a servo saver. Same for touring cars where you might incur a high speed crash.

Think about it, what does a servo saver actually do? In case of a fast and hard hit it will flex on order not to put excess strain on the servo. Now, for a crawler or any slow moving vehicle you will not expose the servo to such impacts. The only actual use of a servo saver in a Tamiya semi tractor truck or any of their off road threespeeders is to protect the servo from a poor setup (incorrect linkage/EPA setup).

Although william is pointing in a good direction for where to source a strong servo saver, I second Pete359's reply and say that as long as you have setup the steering linkage and radio end points you do not need a servo saver with these cars.

.......and radio end points you do not need a servo saver with these cars.

That right there is the problem. Not all radios have this ability and therefore need the saver to protect the servo.

I always use a saver, but as Mouton and Pete said, you can do without it.

Yes I see the points not for a servo saver, but having stripped gears in big 1/4 scale servos with servo savers in place I just think its safer to use one. Say for instance the front wheels or wheel were to get jammed between a rock or rocks and you were unaware and tried to steer, the gears inside these servos may be strong but if there is a something not allowing the wheels to turn then something has to give and I would imagine that the gears would strip.

I run my TXT-1 with hitec 645 mg metal geared servos, without servo savers.

I have trashed one on the rear steering before, steering it whilst pulling a wheelie in thick grass managed to strip one of the metal gears.

I've got a blue bird 14.5 kg servo in my high lift. Again on grass it snapped the servo savers C spring part in half!

I now use a nylon C spring thing on the stock servo saver, with a small cable tie wrapped around it. Cheap and very effective :LOL:

[piepie31]

I know mymonsterbeetleisbroken they can easily break the high torque is there for the power the gears can easily lose a few teeth. I've ordered the tamiya high torque servo saver for now and c how it goes.

[william]

I like climbing stuff, tall rocky hills and when it comes tumbling down I have stripped a horn. When I took the same truck back out on the same hill some 15 minutes after putting on the ofna saver it tumbledvagain. This time I could keep driving.

It comes down to preferences, me I like using a strong saver over a horn because A I'm cheap, B I want to run and not go back inside to wrench for a mistake.

Hi-torque saver with hi-torque servo -- kind of makes sense to me.
Think also of track rod ends, steering linkages etc.
Best if something that is designed to give is in that "circuit"

[Mouton]

Not all radios have this ability and therefore need the saver to protect the servo.I beg to differ as the best way to protect a servo is to properly set up the mechanical linkage. The importance of this is also stressed in all transmitter manuals I have come across. That is what we did back in the days before advanced radios and it is still the most important thing to do when installing radio gear. Doing so is the best and only EPA adjustment you will ever need (even though I too sometimes fine tune EPA with the transmitter). It may well be that many skip this step or do it poorly - but that itself is another problem.

piepie31, when you have a servo saver in place and still strip the gears, then the servo saver does not do the job properly, it is too hard. When you say quarter scale servos I immediately think of the problems with several of FG's off road models since most of them over the last two years have had ridiculously strong servo savers...

jizziee, I use Tamiya's High Torque servo saver on my High-Lift and it works great. I know others use Kimbrough servo savers and Traxxas Stampe's servo savers with great success too.

[piepie31]

Mouton it is the fg's that I am refering to. I undertand the servo linkages have to be set up right. My only worries are having the front wheels jam up aginst an obstacle and have the servo rip itself to bits.
