If your servos are all programmable you can get the hitec hpp-21 programmer and set the center points to the lengths of your tie rods. If you dont want to or cant go that route I would recommend turnbuckles as your tie rods so you can adjust the lengths of them to set your toe in/out and lastly you could use a 3rd tie rod to tie the two together once all your settings are set. Hope this is what you were asking. programmer info here: http://www.servocity.com/html/hpp-21...rogrammer.html |

It seems like your problem is actually the rotation direction and that is programmable with the programmer. Turnbuckles are probably a good idea just to make small adjustments easily without having to reprogram every time. | |

There should be no issues. the servos turn clockwise, or counter, both at the same time. it does not matter shat direction they are pointed.

I would ditch the tie rod and just run one servo for each wheel. Its going to be a pain to get all that perfectly centered so they dont "fight each other". Its probably not worth it because if they are off at all you will just burn up the servos, plus it will get the extra linkage out of the way in front of the axle. | |

You need a tie rod, otherwise if you had one wheel bound up, you would only have half the available power to move it. Its just not that hard to adjust everything to work together, it just takes a little time. | |
