Your servo may require a different amount of plastic spacers between servo and servo mount. The position of the mounting tabs can make a huge difference.

I fixed my steering interference problem. Best to leave a note here with what I figured out to close the loop.

The manual (p12) calls for a 2mm spacer on the bellcrank arm plate. That was not there. Removing the ball stud, adding the spacer, and then re-bolting everything else up did the trick.



The 2mm Aluminum Spacer called for here was not installed.

What is everyone doing about the front arm breaking problem. I may not be the best driver but it does not take a very hard hit to break the front arms on this car. I also have another make 4wd wheeler car and arms last months compaired to minutes with the yz4. I have tried the new +1 arms and find them no better. I remember seeing something about other brands fitting but cant remember which ones they where. I like the way this car drives but arm breaking along with shock caps is getting old.

The +1 arms are not new, they are from the previous car which was supposed to be stronger.

For shock caps, I went with alloy ones right way.

Have you checked your hingepin blocks as well as the inserts to see if they are tweaked at all?

I am hoping they look into offering the front a-arms in whatever the previous material was for the yz4 as it seems those a-arms were pretty strong.

As for the rear hubs, maybe aluminmum ones will help those folks out having issues with the rear plastic ones.

Had a good day at the track with my car and came home in 1 piece for the first time. I did hit a couple walls but it made it. Had a new fast lap and car was fun to drive. Ordered new front hingepin blocks and pins along with alu shock caps. Hope they work Also got some more arms just in case

If you are looking for a more durable alternative to the front arms see the post above.
FYI if you are looking for suggestions/fixes for things take some time and read through this thread or search it I think you will find lots of good information.
As far as the post above about the rear hubs and pulling ball studs out..... I have had zero issues and I am using the stock hubs. A suggestion is to verify the length ball stud being used as it is a common mistake for people to add washers and not add length on the ball stud.
Also to strengthen each hole add a set screw into the unused holes so as to firm up the area around each hole and therefore make it stronger.

I have read through the thread and have those arms on my buggy with no better result. Been through 6 of them. I hope the new parts coming helps. Thanks for the input

I've never had issues with rear ball studs either. I have seen problems with the fronts though. My recommendation is to thread a set screw into the unused hole on the hub carrier. This will prolong the life of the stud and the plastic.

I think most of us accepted that we weren't getting new arms quite a while back. In fact, Yokomo has doubled-down on their use of hard plastic since this kit came out, making it seem even less likely.
It will be interesting to see what the eventual next kit brings.

how much performance difference do you think the different style rear wings make? 2 types of stock, jconcepts has a few, lmr brand, etc... all hype? just throw any one on and roll with it?

Last weekend I had a proper tuningday at an amazing track (Racing Arena Limburg). I went with a heavier shock package on the front which countered the lifting inside rear wheel. A thicker front swaybar (1,6 -->1,8) is also a must on the high grip EOS carpet.
I tried a higher diff but it didn't do it for me. The standard height is the best imho.

The car is just amazing, very easy to drive, even with brand new tires.

Edit: I destroyed 1 front arm but it was at full speed on the end of the straight where a random dude decided to cross the track...

So im looking to get back into wheeling. Sold my old 22-4 a few years back and now I wanna at to my races. Been looking at this car for a while now. Not sure if you guys have covered this but I noticed a price reduction on Amains site. New car soon possibly...?

thoughts on rear wing placement? do you guys just mount them using the hole dimples or do you move them x amount of millimeters forward/backward?
