These titanium hinge pins seem like a popular upgrade. I would not want to have the pin pop out in a race.

This is the set up sheet for this car. It is amazing how many adjustments there are. Different washers and shims and bolt locations.

The rear shock bolts are left hand thread. That’s is why I was having trouble getting them out. I did not get a manual with this rig. I do have an online version and found the instructions. Left hand thread is for the left side shocks. Who ever built this put right hand thread in front and left in the rear. It’s an easy fix.
Over time, it is said that the shock pivot balls will loosen the screws. The left handed screws, used to secure the bottoms of the shocks, are placed differently on the EB410 vs. EB410.2 depending on which way screw is going into the arm.

I use right righthanded button head screws to secure the shocks on all four corners of my ET410, and have not seen any significant loosening in three years of use. Now on 1/8 scale RCs... the screw loosening issue is much greater, and some companies nowadays will use keyed shock mounting pins to combat the problem.

Here is an insert chart I made up for my ET410:

If you look at the EB410/.2 manuals, they show .5° and 1° of change when adjusting/using different inserts (pills). The printed different degrees of change between the ET410 & EB410 platforms had me thinking.

The ET410 & EB410 use the same gearboxes, ABCD blocks, hinge pins, and inserts. Why are the amounts of change different when adjusting inserts? I asked around, and 18 hours later I found out that there is a misprint in those EB410 & EB410.2 manuals.

Getting the rear yellow springs today. The set up sheet calls for yellow front and rear. What it had was softer in the rear and stiffer in the front. I’ll get it all together tonight and practice tomorrow.

The race seems to be heating up. The 4wD buggy class was a bit under represented in the first couple races of the season. But they just did a role call for the 4wD buggy class and a lot of people responded. I’m pretty excited about that. The 4wd buggy is the easiest to drive and it’s also one of the fastest. My only goal at this stage is a 20 second lap. Let’s see how it does now that it’s completely set up according to the set up sheet.

Got my yellow rear springs and set the ride height to 22 mm rear and 18 mm front. The spring adjusters are now even and about five mm from the top. Before they sat about mid way and that’s when I questioned the springs.
Also finalized the toe. 3mm out front and the rear has 3mm toe in. The Ackerman says to start with 4 washers and I changed that to 3. It affects power on power off turning. It seems pretty good with 3 but now everything else is different. I missed tonight’s practice session. But tomorrow will be good to see how that does.

About three hours of practice today on a very loos track. I like the Fugitive tires a little better than the Double Dees. And I really learned some more of the track. Car rocks it’s so easy to drive.

I really like this buggy. I finished last place but could not be happier. The competition is serious but I did get a 21.399 second best lap time. My goal is 20 second laps.

What a fantastic machine this is. I am trying not to have favorites. But watching this thing clear a triple jump with ease and then slide a 100 deg turn in a cloud of dust is just the coolest thing ever. And in the A main I got into an actual race with someone that passed me and I just hung on. Not trying to pass, staying just close enough that maybe I could catch him in traffic or something. Nope he walked away. But not before I scored a personal best lap time.

I keep reading and watching videos about the new EB410.2 and how much better it is over the original kit. I really like my EB410. But I might have to upgrade.
