If you want to change things to the car that is fine. But don't create problems when there isn't one

I thought I mentioned that it is more a matter of preference that you make the shocks more straight...
Perhaps if I post less, people will remember better and replies wouldn't get lost so easily !

So you're saying I should keep it in a rotating glass casing with spot lights around it?

Well, keeping it in a rotating glass case would be a good idea if you intent to give it to me to test the car in its best possible form...
As for spotlights, not a bad idea if you plan to join those racing around at night in KL!

I think Goldfinger mentioned that it was 1670 grams race ready with personal transponder, body and without fuel.

Steering link
Ok, let me try to explain the steering link issue. I've used the picture of Rookie Solara to clarify. I hope you don't mind. One thing to remark is that the angle of the link is a lot steeper than in this drawing. So the 90 degree to the link position of the arm is a lot more forward.
At first look it would seem obvious that the link and arm need to be at 90 degrees. That "looks right".
The reality is different. It is not the link that defines the movement. It's the realtionship of the arm and the servo saver. The link could be a wire tied in a knot or shaped like a "Z" it would not make a difference.
The servo saver moves in a horizontal plane. So ideally the servo arm should move horizontally as well. Unfortunately sevos have no horizontally moving output but a rotating one. So we need an arm. To get left and right movement the same the arm needs to displace itself in both directions the same amount in relation to the movement of the servo saver. This means the horizontal movement is the most impoertant part.
Also you will notice the arm on the servo saver in the neutral position is at a 90 degree angle to the link. That means it you turn left and right the movement (forward and aft, but also left right circular movement) is the same).
So, now look at the picture again. If you align the lever at 90 degrees to the link and turn. If you rotate the arm forward (counterclockwise) you will have a little forward and then (because it is a circular motion) a lot of downward motion. If you turn clockwise, the ball will move sideways mostly and a little up and then down. So in this way both sides have different motions.
If you look at the picture where the arm is vertical in the neutral position you will get the same movement in both sides (horizontal and down).

One last thing.
In the picture of D's car I noticed that the ball Is shimmed outwards. This changes the angle of the link to the saver and means you may create unevenness left and right that way, which needs to be corrected ssomewhere else. If I compare it to my car (which uses a Sanwa steering servo) It seems the ball is a lot more to the middel of the car (even when I put my steering arm in the same position).
In the end it all comes down to: If you get left and right the same steering with epa settings within 10 point you'll be allright!

Julius.........the reason I created this diagram is for you (and others) to explain the full detail with at least a little picture so dumb ass like me could understand it more...please, if you find me helpfull and want me to create some quick diagram, please let me know.......(btw, what department should I send the drafting bill to..? Serpent USA or Serpent HQ in Europe..? For real....another 710 as a reward is fine for me....J/K)

Ha!! Here are our (mine and Pineapplet's) machines for next seasons' battles!!
They look and feel good....haven't ran them yet due to terribly wet weather last week!

The reason why the shim of 0.5 mm was introduced was because it seemed like the link could rub on the front belt at certain steering positions.
Secondly, when turning right (servo horn pulls backwards towards the tank / clockwise), the linkage ballcup can bind against the servo arm at the furthermost end point of the servo. Shortening the linkage rod and the ballcups enables the servo arm to be moved forward and when the servo arm moves towards the tank to make the right steering, the ballcups will not be at the end position where it will rub against the servo arm.

pretty descent price also @ $359.95 each.
shipping sucks because they charged $40 for both of them.
ebay has them also. one guy selling the kits for $399.... and the other one is selling them for $368 + $12 shipping!
good luck

hey you guys who got your snakes already.... does the kit come with a battery pack??? if not, where did you get yours and what's the best deal out there??
thanks a lot
thanks a lot
