Hi, New Yokomo CGM Onwer here.
I bought used one and it looks great.
But I need your help.
Where can I get parts online ? (none of LHS carries parts)
Who has good price?
where can i get Differential for front?
I also noticed Rear Differential output is Plastic
Would this hold up to my 6t Brushless?
where can I get steel one?
I'll appreciate any input.

ran the car yesterday.... It looked that it had no droop left up front... I guess I had been trying too hard to get onpower steering already! So I put like 2mm of droops, and I stiffened the rear (I ran RS greys rear, and yellow fronts). The car was close to before (with RS whites in the back). I then tried to go back to soft springs on the advice of a buddy of mine who said it should work... the car would roll too much. Then I tried medium springs again (RS whites and yellows) but stiffer up front... I dialed in more dual rate to compensate, a little rear camber, and then the car was awsome, it was easy and I could brutalize it if needed, but with enough steering on and off power to be quick... got very close to my personal record (I was at 11.2), which was obtained in different conditions (track was soaked with tire sauce).

I'm very happy with the car!

Next step: go to stiffer hydraulics (running 3holes 40WT all around so far). This is still my 17T setup, so it's probably a little light for 12T...

Later,
Paul

Hi friends. Greetings from Malta.

BALL CUPS. Get a set of Schumacher Ball Grippas. They are a much tighter and better fit all round.

ACKERMAN. The reason you get more steering with more ackerman is because by introducing ackerman your front wheels track better around a corner. With no ackerman at all, if you turn full left your front wheels would run parallel. However the inner wheel needs to turn in a smaller radius so it will drag, causing understeer.

Add some ackerman so that your inside wheel turns slightly more than your outside wheel, thus they both track their own radius and that should help the car steer better.

There are lots of ways of playing with ackerman. Rayspeed have done it by moving the steering pivots further back. You can also do it by varying the length of the steering arms.

A bit of front ackerman also looks after your front tyres better for they don't scrub so much.

DRAGONEAU. The plastic diffs are perfectly OK. I don't think I have ever broken one in years. Don't take the rings off them though. If you really insist on metal diffs then go for the MX4 ones, but it shouldn't be necessary.

SHOCK SHAFTS. Sosidge beat me to it. The AE shock shafts are an imperial size, the Yoke ones are metric, so if you fit AE ones on Yoke shocks they will be tight and conversely if you fit Yoke shafts on AE shocks they will leak.

Sermon complete.

Oh by the way, any developements on the Billy Easton to Yoke saga?

Regards

Joe from sunny Malta.

If varying the length of the steering arms, wouldn't that change the toe of the front tire???

I have my front toe set at neutral( 0 Deg) now, and if I want more ackermen then setting will this change my front toe??

I'm confuse..

The ackermann adjustment is seperate to the toe.

When you change the ackermann, you reset the toe to suit.

Thanks Sosidge....

OK If I understand this correctly, I can alter the length of the steering arm( this is the part that connect to the servo saver, right??) and then adjust the steering that connects to the steering hub to get the correct toe.

Please correct me if I'm wrong, and have you change the ackerman before?? Please let me know which if best, for a tight track??

Thanks for your help again.

THE NOI.

At the risk of being repetitive, ackerman only alters the relationship of the inside wheel's radius to that of the outside wheel. The steering arms we are referring to are the arms from the steering posts to the hubs. Those are the ones you adjust to get your toe in correct.

The rod which connects the two steering posts can be shortened or lengthened to give you different ackerman too. Hubs with different steering lugs can also vary the ackerman. There are plenty of ways to do it.

The important thing is that your inside wheel turns through a smaller radius than your outside wheel. You can check that very easily.

Hope it's a bit clearer now.

Regards

Joe from sunny Malta.

As Johnbull said, there are many ways of increasing akerman. I noticed you said that you run 0 degrees toe at the front. If you are merely experimenting and trying things out, why not try 2 degrees toe out on the front and see if you like that. In effect this is a cheat's way to get a little more akerman angle. If you prefer it mess about by increasing actual akerman angle and try running 0 or 1 degree toe out.

Running less akerman can actually make the steering feel more agressive. With the right akerman angle - somehow the steering feels more progressive and as a bonus, you get less tyre wear.

btw this is ryan isn't it, what day you going to portland. and which surface around here would you say is closest to portlands.
Nope, this is Sam (Forbes). I think I'm heading down to Nats the Wednesday before. I couldn't say which surface is closest because I've only raced at Hobbytown (race run by Rain City). What I can tell you is that the Portland track seemed much more abrasive, we were only getting about 4 runs on a set of tires, maybe only 2 good runs. The track was small too, but maybe it'll be bigger for Nats. BTW: Is Ryan running the Yok now? I thought he was running the Xray.

JohnBull: Thanks for the info, your explanation makes sense.
