I have seen on alot of the setups guys are running the flat rear arms. What is the advantage of running them? Also have seen there are 3 different part numbers for the arms. Which ones are best??

question, ive noticed on tebo's set ups that the steering drag link is turned so the arrow is facing to the rear and has moved his caster blocks back 1 mm wouldn't it be the same as having the arrow facing forward and having his caster blocks forward?
thnx Mike

Not really. It's changing the weight distribution relative to the tires. It's shortening the wheelbase but makes it more aggressive as well.

So does anyone have a pic of the 3rd hole drilled on the RB6 arm?

Just want to make sure I'm doing it right.

No, the mip axles are long enough for aka wheels.

What bodies are guys running? I was looking at the Sweep Muzzle and Proline Phantom... Not overly concerned with the looks... But more performance stability.

I searched the thread and could not find anything on this:

After assembling the transmission there is some end play in the top shaft. I just installed the new Schelle top shaft and same result. It about .5-1mm of play. Is this normal and should I try to shim anywhere to reduce this? Once I install the gear and slipper it's still there.

You can certainly shim it out, but it shouldn't need more than .02mm at most, if it's really .5mm to 1mm then it sounds like something is wrong, perhaps a bearing out of place or missing. Which bearings are you using?
