NIX91 Questions and Answers

[Minisforever]

Rears are a yokomo CZ-825 deep dish offset 12. That's for the roar 2.1 that associated ram in 91. The 2.2 version of the wheel is part # ZC-835.

So I mock fitted up my car and wow the bump steer is huge. Any suggestions?

Sounds interesting as I can't see the problem in my runner.
After tuning the 3d-model with my current real car setup - teoretical measurement for bump in was 1.2 deg when chassis touches the ground (25deg arm travel). With the real car I had hard time seeing anything.
Bellcrank link = 38.5mm
Steering link = 72.8mm
Camber link = 64.1mm
Bump steer spacers = 3x0.8mm

When adding lenght to bellcrank link and bump steer spacers, zero deg bump in can be reached easily.

Thanks for the wheel info mini!

Niki, what is the recommended total length of the center bellcrank turnbuckle with ballcups installed?

[GoMachV]

He listed 38.5mm above, I just checked mine and its shorter. I used the stock bellcrank hole position to guess at length, just like a standard RC10. That gave me some bump steer too so I will try his measurements above soon and see how it goes

[slotcarrod]

But is that from center to center of the ball cups or end to end?

[GoMachV]

On center

did anyone else have to drill out all the arms and other parts so the pins would fit? also my front bulkhead wasnt drilled out so it could mount to the chassis (the 3 screw holes) i know they are little things but this wasnt a cheap kit not super happy.

[GoMachV]

Yes all holes have to be made round. This is a limitation of 3d printing when the printer is not your own. He can't control the direction they print the parts and when the holes are vertical vs horizontal they will be shaped differently. I assure you the holes he spec'd are round lol. As Jake mentioned use a 1/8" NEW drill bit (or if you have a .127 ream that is what I use)

I think you will find that the holes are plugged with powder, that's how my parts have arrived. I think it happens during the polish. I believe it is a #43 drill that I used (came with the tap)

k thanks. i guess iam used to oldrc.com printed parts when they all fit perfect with no issues.

well i was told that the stock rc10 dogbones would work but they are a little too short? any suggestions?

Stock dog bones do fit and should not be anywhere close to being too short. Post up some pics of your problem and lets see if we can get your problems sorted out. You are the first person I have heard of having issues with dog bones being too short.

[GoMachV]

+1, I'm using them and they are perfect. What have you done outside the standard recipe? Are you using a spacer in the outdrive and a spring in the stub axle like you should be? Are you using the correct side inner mounts, with the pins inboard of the screws?

[hugger19]

here is the pic. used all stock rc10 parts hubs axle dogbone. am i missing something?

[SFC K]

I thought the spring goes in the hub side...
