Thanks
I have the same problem and did everything you mentioned and tried

movable beam will roll to the right as well, thus showing tweak.

Now turn the left front spring harder and the movable part will roll
back to the left. No tweak but not a perfect chassis...

Just try it.
Now I see what you mean! Hmm, interesting.

I have a slightly off topic question: With my Tamiya Surikarn, most of the weight (due to the battery arrangement) is on the left hand side of the car. I tweak the car so that the tweak station shows that both sides are balanced, but looking at the chassis, I see one side higher than the other, due to the greater weight of the batteries.
This is also relevant for those who haven't got a prefect left-right weight distribution, which without the addition of some weight to the car, is normally the case.

Am I tweaking my electric car incorrectly?

Cheers, Mark.

For any all wheel independant suspension car the tweak board is not handy because of the reasons in my earlier posts. A tweak board is handy on pan (solid rear axle) cars.

Also on your electric you can use the pick it up in the middle technique.

I probably do this as my step one when tweaking. At first I isolate the front by placing a Hudy Block under the rear of the chassis. The front wheels are on the swing-bar and I adjust the front tension until the front is balance. Then I swap ends and do the back (with the Hudy Block under the front).
After doing this, I then remove the Hudy Block and adjust the tweak for the front and rear once more.
And finally, I connect the sway bars and adjust their length (or the cam thing) until the tweak is once more level.

Do you mean, that it would be better to always tweak with the block underneath one end of the car?

Cheers, Mark.

It's absolutely true... I guess thats way the laser tweak station would never be a hot item, buble one still more self convidenced and make us more to believe But I prefer without it

Another note: have not done any maintenance on my S710 since its first race meeting (with some practices and engine tuning) except... cleanning the car and engine that takes about 30 minutes top (include removing the upper deck). Everything still turns smoothly. This is what I called a FUN SPORT Will inspect on all moving parts after the upcoming second race and see how forgiving it is on maintenance.

Default 710

Yiiiiiiipppppeeeeeeeeeeeeee! My 710 has just arrived.

What would you guys recommend out of the following servos for steering duties.

KoPropo PS-2113 FET or PS-2123 Digital.

Futaba 9402 or S9350

Sanwa ERG-VB or ERG-VR.

I fancied the Sanwa ERG-VB, but been advised that it may be a bit overkill on the 1/10th, my LHS is selling all these around the same price bracket.

Cheers Guys

I never have luck either with KO or Sanwa servos, they all seems to generate noise which make it always unsteady (I tried until 2123/43 and ERG-WR I believe and it was on my electric cars).. I would always go with Futaba

Thought about this a little more and please correct me if I'm wrong:

If I first of all tweak the front and rear by placing the Hudy Block underneath the opposite end of the car to which I'm tweaking, I will know that the front and rear are independantly tweaked, and I can be sure that when the right front is too lightly loaded, then I must create more tension on the left rear and less on the right rear. i.e. I would have a known starting point and would end up with a balanced car??

Would this not work as well as the lifting method?

Cheers, Mark.

Keep the faith brother

Well in my Computer Centre here at home, I've got two Sun Ultras, two Linux XPs and two Mac laptops - bliss

A mixture for my photo work and my programming work.

Julius, I must say ... I'm confused!

By fixed beam, you mean the rear beam of say ... the Speedmind Tweak Station?

I think that's what is meant to do isn't it?
