ET 48 "Random / Stupid Questions" Thread

[TeknoHov]

I've seen this thread format on other forums for questions that dont need a dedicated thread, and my 1st question fits the brief (I think!).

Following the manual, the rear hub assembly advises 3 shims are placed to the rear, meaning the hub is not central between the arm. Have you stuck with this or moved a shim or 2 to the other side to centralise the hub?

This adjusts the wheelbase, more info here:

Thats a really helpful guide, and wouldn't have appreciated a couple of mm would have a significant effect!

Second build question, steering limits.

I appreciate this may be a non issue, as I've not yet mounted the shocks, so the front arms drop down as far as they can. When turning the servo saver, the right hand hub moves further, almost to the steering limiter, while the left hand side hub is no where near the steering limiter.

The steering bar tkr8100b is hitting the gear box, as though its the wrong way around..

Edit: typos

You definitely want to hit both steering stops with equal throw.

Some things to check

1) verify the length between the ball ends on the steering links are identical... best to use a caliper
2) verify the ackermann bar is centered
3) verify all tuning holes used are same on both sides, same number of bump steer washers, etc...
4) don't forget to set EPA so servo doesn't bind when hitting the steering stops.

Thanks @Billl DeLong

Checked 1, 2 and 3. Used calipers for all the links and are within 0.05 mm of each other. Shocks and servo arent instslled yet.

What i can see is block A is .5mm protruding past the end of the chassis, and the bumper doednt fill all the inderside indent.

Should the a block be flush with the end of the chassis?

Thanks!

Maybe just finish the build, chances are the camber settings are off which may be the cause, and that will all get sorted out once the electronics and wheels are installed

 

[TeknoHov]

Following your advice @Billl DeLong .

I removed the front assembly, as I noticed the end of the servo saver column wasnt parallel with the milled slots of the chassis.

Have corrected them.

I also hadn't fully screwed in one of the droop screws, fixed that too.

The throw is now equal, the ackerman plate continuing to hit the gearbox at max throw.

 

[TeknoHov]

With the front shocks assembled and attached in the stock position, the throw is perfect, hitting both limits without the ackerman plate hitting the gearbox.



Edit: typo fix.
