Servo Saver Help

[ian_foster]

Hey Fellas,

Question for you: I have a Tamiya Tundra which I had ALMOST completed today, build wise, I quickly assembled all the electrics and was doing a drive test around the house when PING the servo saver clip thingy went snap and flew across the room in two halves. I had tightened the screw way too much so obviously there was an issue there (idiot factor). I have installed an MKS DS1210 high torque servo for the steering, which is set up as stock (although I do have a Junfac set up on the way).

So, questions... is my servo possibly steering too much and I need to adjust the max turn rate?

And, most importantly, are there cheaper saver thingys available cos it's cost me £13 to get a new G parts ordered for one bit! Seems like these things would be better made out of a softish metal rather than hard plastic which snaps...

Thanks in advance for helpful replies

Which servo are you using for steering? Curious how much torque it puts out. It takes a lot to break the servo saver plastic "spring".

I'd check the left and right maximums and limit servo travel so it doesn't try to push the steering assembly beyond its limits.

Hold the front end off the ground and test the steering and keep reducing the left and right travel until the servo just barely stops trying to push the wheels too far. You'll be able to tell because the steering system will tense up at the edges of travel. You'll probably also hear a lot of howling from the servo because it's straining against the turn limits.

You could also think about getting a Tamiya part number 51000 hi torque server saver. Much better than the plastic types and less slop too.

Good luck!

The servo specs are listed here:

Interesting you mention the high torque saver, I rang Modelsport (in the UK) to enquire about that and the guy told me I'd be better of getting hold of an original part, which they didn't have in stock, I got it elsewhere.

Well, I done a bodge on a servo arm that came with the servo (cut off three of the fins, drilled out a hole for the ball connector), dialed the steering trim right down and then worked up until the knuckles were just shy of maxing out. Turns out it was 90% so have had it at 100% was putting all the extra strain on the saver spring hence the ping.

Valuable and expensive lesson there!

The best servo savers are made by a company called Kimbrough, they run about $6 and outlast the rest of the car.

There's a "repacked" version of that in the UK by the name of Trick Bits. They look the same anyway:

the only one I've found so far is white though and as the servo will be going to the front of the car shortly I'll have to search around for a black one or it will ruin my whole outfit!! ;p

I'll second the Kimborough savers, I have a couple fitted to my trucks and they are great. (Not as hard a plastic as the Tamiya high torque ones)
