Default flipping the chassis

Ok guys I have been reading the WK forum for a while now, and have noticed that it is very common to reverse(flip)the chassis. What all is involved. I haven't really seen anyone post instructions about this. I am assuming that it is a lot easier if you have a axle mounted servo instead of stock. can this be done with the stock steering? I kinda like the stock location just because it looks more scale to me. I would appreciate any kind of info on this as I am new to this and am building my new WK to be a trail scalish rig. Thankx guy

I have done the reverse chassis with the stering servo still on the chassis
the link and servo needs to be mounted on the other side of the gear box and the link to the front axle must be 94mm from inside to inside and you need to fab a new support for the servo

I hope this will explaine it enogh
if not I can take a few pics

Regards

Depends on how you have it setup, I broke the stock saver so I put in a standard long servo arm which made a difference as did making the adjustable upper pushrod.

thankx Bjoe that picture actually helped a lot. I had an idea of what I wanted to do, but it really helps when you can see what others have done.
It looks like you have swapped your stock servo? Did you notice a difference in good or bad when doing you steering mod?

I went a little out the box as my chassis isn't "flipped". Instead, I just moved the battery to the front with velcro & rubber bands. I needed to move the shocks down a bit to allow full travel in the front. With my trimmed springs I don't have much uptravel anyway so it's sort of a droop setup. I have bumpstops to prevent hard bottoming too.

I did this because I cut & lowered the batt box and stuffed a dig servo in it.

This is what I run and it's a nice improvement over stock for a great price:
http://www.jpcustomrcs.atomicshops.c...75/4462001.htm

We get the SF-1 out the box...
I can't find specs on the SF-1, but the SF-2 puts out 90 oz/in

If I had to guess I'd say the SF-1 is probably closer to 60oz/in.

"the HPI SF-1 servo provides around 40 oz-in of torque at 6.0 volts"
from an RC Universe review...

Just swap the motor wires from red-peach and black-blue to red-blue and black-peach (for the stock motor btw), red-black and black-red, or resolder the red to the negitive side and black to the positive side of the motor.

DON'T SWITCH YOUR BATTERY WIRES... Switch your MOTOR wires.
