I'm yet to start building my zx6, but looking at the instructions there is no mention of this needing to be done, unlike in the zx5 instructions

Would use the same servo in the ZX6 if I could as it's lighter than a regular size servo and would allow me to swap between cars if needed. But does the 4WD put a LOT more stress on the steering servo? Should I be buying a beefier servo?
I ran shorty in my 4wd car for a while, BLS551, could not notice any significant difference between that and the 451. Having a servo saver will help as well of course!

The front pills are the same as the RB6 but the rear are bigger ones marked A thru to F
I should have thought to Google the ZX5 as I got my answer with this chart

Side note I'm going to try a Spektrum S6070 servo first (only because I have one NIB already)

Well I got my kit today and nearly finished the roller. It's an awesome build so far. The quality is awesome. Here is a pic of it.

Very nice Joe, I did do some more building last night but just haven't had a chance to get the pics up.
I will do some more building tonight and hopefully get it to rolling stage.

Joe how have you found the chassis flex? I am surprised how much there is

Yeah the chassis flexes a lot more than I thought when I pulled it from the box. Once all the braces are mounted its pretty much how you think it should be.

Ok here is where I am up to with the build.

I have a lot more pics than this but didnít want to blow the thread out with another 20 odd photos.
I will get to the body over the weekend and once the black wheels arrive Iíll do the final pictures then.

I must say this car went together well and Iíve had a blast building it and yes I have not put the sway bars on as I need to go buy another 3mm drill bit as I canít find the one I have.

It's supposed to keep the dirt out, but after 1 run they will start to tear apart

Are the spindles and spindle carriers beefier than on the zx5 by a significant amount?
