Once the diff housing it put on, I guess you could say the bulkhead is built around it. You kind of clamp down some plastic pieces to each other, around the diff housing to form the bulkhead. See below. The top 2 stainless screws are the buggers that stripped out on me - shown are the new ones. Notice we're adding some blue bling to the picture now.

Hey, who put that dog hair in there!? [8D]

Now it's time to get the rear shock tower in order, along with the wing mount. More blue bling.

Using the provided tamiya thread lock anytime I'm going into metal with the screws, as the directions indicate. Am also using grease on the screws going into plastic parts, to avoid the screw stripping episode again. I spent some quality time with the dremel to make a notch to get the aforementioned screw out tonight. Fun fun.

And here's the rear shock tower and wing mount on the rear bulkhead/diff housing. It sure is shiny. That's not gonna last.

More pics in the next few days!

Eman,

Here is a pic of the shock bladders, the one on the left is the stock bladders and the one on the right is the Losi 15mm notice the thickness and the size difference.

The stock ones were so bad they would leak if I just read the manual [:@] But now not even a drop


BTW I suck at taking pics[:'(]

Thanks for the pics, collector. I ordered the Losi bladders the other day, should arrive soon.

So, I got a little bit of progress on the build over the weekend. Started with the tie rods fo ALr the rear suspension. They're beefy. See the comparison pic to the 1/10 Durga tie rods. Also notice the near bald tire on the Durga. Seemed to occur shortly after the MM 5700 install into it. Coincidence? I think not!

Here's a pic of one of the rear hubs built. A drive pin goes through the hex and drive axle, and is held in place by a grub screw going into the middle of the hex itself. Pretty nifty. For some reason, it was a bit of a pain getting those pins in though, for one of mine.

Here are some shots of one side of the rear suspension installed. Lots of options as to where to hook up the tie rod to the chassis and/or hub. More than I can possibly comprehend with my wee little bashing mind, anyway.

One interesting thing to note: it uses hinge pins to go through the lower arm (and hub) to hold in place, with a lock nut on the other side. However, the hinge pin seems overly long - even using the required spacer (as per the manual) on the lower arm pin, after you tighten the lock nut all the way down, you can still slide the pin back and forth a touch - and make the spacer move around (thus making it a bit useless?). Take a close look at the pics to see what I mean.

Any other 801XT builders get this? I could put in more spacers I suppose - it's just weird. I triple-checked, and yes, I'm using the proper hinge pin/screws too.

Here's a bird's eye view of it so far - I've since installed the right side hub and drive shaft (after the pic).

Huh, weird. The pins I use line up exactly to the 1:1 picture in the manual. And are from parts bag A, which this section is all about. It's not like I chose the wrong one - there are no others. I guess I could slap in a few extra washers/spacers and call it a day, where there is play (mostly the lower arm).

Here's the front differential and housing/bulkhead being built - quite similar to the rear one. Nice shiny shock tower again, but a bit shorter this time. Once noticeable difference was the fact that I didn't strip any screws going into the diff housing. Yay me.

Looking good Eman. I want to see how the BL conversion goes. I have a suspicion the Kyosho STRR conversion will also work on the 801xt.

You might be right - can you link to that conversion for reference? Should be an interesting comparison.

Here's a couple shots of the front hubs/carriers/whatchacallits. Seem pretty durable!

Here are some more shots of the front suspension installed, along with the hubs/carriers.

I didn't have any play (or need of washers) on the front hinge pins like I did in the rear ones. Interesting. Also note how the center shaft is angled upward coming out of the differential. I'm no expert, but I'm guessing this is due to the fact that the front of the chassis plate has a kick up to it, so this compensates for it. Cool.

We now have a wee little bumper installed as well. Yippee!

Now here's our front sway bar installed. I'm no racer, but figured I'd put in on anyhow, just for fun. Little grub screws help hold it in place too.

Here's several shots of the chassis plate. Things get fun now. It has indentations for the diff housing and whatnot.

That's all I really have to say at this point. I'm tired.

2 more of the chassis plate. We just can't get enough of this plate. Notice the afore-mentioned front kickup. I hope you were paying attention. There will be an exam later this week.

And now we have some plastic side guards installed, as well as a shot of the radio posts and one steering post.

Isn't shiny blue stuff purty?
