thank you for your interest.

best regards.

You'd be better off ordering the parts from Lego, rather than buying on ebay. Also, do you want to motorize every function, or just the drive and steering? Unless you have a lot of parts to experiment with, it is really difficult to say what you need. You might want to check out the Mods and Improvements thread.

I agree saberwing, though I would use an Xl motor attached directly to the drivetrain. It has enough speed, and one l motor drive is not enough to go through both differentials and the straight six and to still be playable.

i want use it for drive an steering only.offcourse, its must have IR and remote.

I recommend to watch the following videos. Among them you will find all the necessary parts and instructions.

For A-model:

For B-model:

I have build both models with those instructions.
