Default Linkages play

Hello Gents,

A question about linkages play. I know it's a much debated topic in RC in general but I tend to believe the linkages play, especially on the steering servo linkage to the servo saver post is huge. Also the steering rods and the camber linkages do have quite a bit of play. Do I just need to replace them or are there better aftermarket linkages I can use. Did a lot of searching already but thought I'd ask here for some good advice....

thx in advance

w.

It depends where the play is coming from. I usually replace the plastic ball joints when wear starts to develop in the plastic but to be honest it isn't very often. If I remember correctly you run the RTR car? If so then the steering assembly has a lot of play in it from the outset. I don't mind a bit of play in the linkages and I actually think it leads to a freer feeling car on the track.

Another thing which is overlooked is the actual play in the steering servo itself. I used to run SAVOX but found the gears very soon developed a lot of play in them which actually made the rest of the steering system seem to have lots of play. I now run SANWA SRG-BX servos in GT (I was already using them in Buggy and 1/8 circuit) and most of the play went away as the servo them had no neutral play whatsoever.

I think the steering rod linkages and the servo linkage are the same as the 3.0. The standard RTR ackerman bar sucks as Serpent puts 3 mm threaded bolts into the metal 3.5 mm bushings instead of using the kingpins. I replaced it by the ball bearing one. The savox 2290 has 1 hour of work under the belt as I burnt up 2 savox 1268's already. It's not the servo, it's not the ackerman. It's only the steering rods and the servo link. I was just wandering whether this is normal after let say about 10 liters of fuel. Replacing is easy but maybe there something better?...

I get more life than 10 liters but as you say cheap to replace. I don't think there is an alternative actually.

Chassis on a flat plate and with the wheel hex on a parallel with the flat plate measure the droop from the bottom of the hex to the board. In general I start with 25mm in the front and 26mm in the rear. I run the car very stiff with very little uplift on the GT.

If anyone is looking for a Cobra GT, I have a brand new ready to run with motor, servos, pipe/header, 811 GT suspension upgrade, gears, springs, sweep tires. Everything is brand new. No time to play, to many hobbies.
