Chassis Flip Guide

[Handsomerob]

Wow this all seems to be geting blown way out of proportion, I did the chassis flip, then I just swapped the wires, it works fine. If you don't wanna swap the wires and are using the stock or a decent controller there is a switch that says TH.REV this reverses the throttle control, switch it and the truck will go in the right direction.

As was mentioned earlier, my pivot arm is now hitting the motor plate, severely restricting the turning radius to the right. Steering throw to the left is unaffected. How did you solve this?

One this different with my setup is that I installed a Futaba 9303 steering servo, which is slightly deeper than the OEM unit. Because of this, I had to change from the stock servo saver to a straight servo arm (I'm hoping the stock plastic will act as my servo saver for now). The servo arm is moving freely, it's the pivot arm that is causing the problem.

it looks like I'll need to make a longer link from the chassis pivot to the axle pivot and probably use a different link from the axle to the tie rod.

I'd really like to see other people's solutions to this problem (that don't involve relocating the servo to the axle).

update: I had to lengthen the steering rod by about 1/8th inch at each end to allow for full steering throw to the right. Here's my WK's thread: Pete's WK project

any updates? I flipped my chassis a while back and seems fine but I also replaced the motor and i am moving the servo to the axle....

but i read about flipping the c hub? why?

[Pete from Houston]

If you're running a motor that has zero degrees timing you can simply swap the ESC wires once you've flipped the chassis. The only reason I can see for needing to flip the axles is if you're running a motor with advanced timing. Such a motor will not work effectively with the wires swapped.

well i got a integy 55t but i didnt swap the wires and all is fine. maybe i switched axles while i was locking them and thats why i dont have a problem? Not sure but my toe in is way off..... wont matter soon building a new chasis for it..thanks though

My steering linkage hit's the purple motor bracket, what's the solution for this?

EDIT: Using the stock servo.. all stock parts.

Take the servo saver off the servo, but leave it attached to the arms. Remove the long link at the axle pivot, turn the wheels all the way to the right, then adjust the ends on the long link EQUALLY until the link meets the axle pivot. Now, reattach the long link to the axle pivot.

Go back to your servo saver now. Turn the radio and ESC on, center the steering trim on the radio, center the front wheels, then reattach the servo saver to the servo. Check for proper steering function and fine-tune your steering trim.


1 note: it would be best if you used a new section of all-thread to replace the long link for the steering. When you adjust it as I explained above, it will leave barely enough thread in the rod ends. I'm sure that if left alone the ends would eventually strip out.

Ok, cool thanks for the help. yeah, im in the beginning stages off a full out rock crawling machine.

Any chance this could be stickied?

yea i couldnt get it lol. i just left my chassis normal and mounted my battery under the servo in the front of the chassis. same thing less work. used velco =P

[clod & bruiser]

yeah im doing that as we speak...but im now gunna give it another go at the chassis flip. i guess what i really dont get is the axle flip...all i do is flip the actual axle right? then ill heve to adjust the knuckles if i undersatnd it right?

[Pete from Houston]

here's my WK thread: Pete's WK project I know it's light on pics, but it might serve as a visual reference for the chassis flip.

Honestly, all I did was:

1) I changed the steering gear around like I described earlier.
2) I switched the motor wires as described on the 1st page by Phase 10.
3) I poked a new hole in the body for the antenna.
4) I turned the tires around (personal preference)
5) I mounted the body with the hood over the battery box.



Are you going to be using the stock steering setup or an axle mounted servo mount? The hardest part of my flip was that I wanted to keep the stock servo location and steering gear. If you're going to be using an axle-mounted servo, it's much more simple.

ok that helps...but now im in trouble with how i would switch the wires... got got not very inexpensive esc in the rooster crawler edition and a novak fifty-five motor...i dont want to fry anything. i have athe th.rev switch on my transmitter but im not sure what to do...help is appreciated and needed!

[Pete from Houston]

positive on negative

negative on positive

If you're motor has adjustable timing, set it to the middle (zero degrees)

switching the transmitter switch won't help (I tried)

[clod & bruiser]

well i got it to work now ill post pics

yes, one.

Why bother?


The differential gears are straight cut. They don't have a weak side like a 1:1 differential gearset.

Someone else is gonna have to take over here. I know what I did is working without problems.

[clod & bruiser]

ditto...its working now
