Domit - Thanks for the word.

ezveedub - When you mount your batteries in the Losi, cut a peice of lexan the same square size as the batt box. Sticky tape your battery to the Lexan and install.
This spreads the load evenly on the bottom of the pack and does not let that screw area comprimise your cells. It also keeps your pack from shifting around in the box which can eventually mess with and strain your wiring.

I used those spacers on my rear center shafts as well. I took one look and knew that would be the way to go.

When the car was tight it would wander all over the place on the straights so I found myself constantly correcting it. With it stock if I hit a good line comming on the straight I can actually scratch my nose and take a break until the end. Much easier to deal with during long mains.

Good thread guys.

the lexan square for the battery box sounds like a good idea. what I did, was just rip the foam out and put in in backwards, so the screw is covered with foam. But your method sounds nicer.

As you can see, the CVD is now "plunged" further into the outdrive cup.
I have done this same mod for my cars since a couple months ago for the same reasons. Although the dogbone only ever popped out once by casing a jump really hard. This has been for over a years worth of racing.

With the flex of the chassis are you guys moving the rear shaft in to far? I wold think if the car flexes like it does that you may bottom out inside the drive cup?
Just a question. Mine is in the stock location.
wondering what your thoughts are?

No, it would have to flex quite a bit more to cause any binding. Either way, do you want a DNF or the possibility to still finish?

on that center drive line mod did you do it to the front.what kyosho shims did you use.Iwas checking the outdrives cups on the f/r diff they had a lot of slop got new outdrives cups and the new cups came with shims installed with out shims same slop installed shims and had a lot less slop the shims are
.2mm could use a .3mm or .4mm thinking about trying the mugrn diff shims
.5 mm is to much

I used the Kyosho 5x7mm shim kit. The kit comes .1, .2, & .3mm thickness. I used a .2mm and then a thick washer I had in my parts bin. I can confirm that your dogbone will jump out. It happened to a friend of mines Losi at the state race tonight. It jumped out after taking a 30ft triple. We installed the shim and washer to his afterwards. On his, we cut the rest of pinion shaft end to match the original flat cut. His shim and washer setup would bind up the pinion & bearing, since the set screw was catching the egde of the flat cut on the pinion shaft and would push the axleshaft into the pinion bearing. These kit is used for shimming Kyosho clutchbell endplay, so use it to for your Losi clutches also.

Those Kyosho shims are ur best freind when it come to shimming.....those and OFna 5x8's are A MUST in every racer's tool box....i CANT COUNT how many guys buy the bulk ofna shim kits to only get like 2 or 3 5X7 shims and the rest is practically useless.....THank you kyosho and ofna for making these shims. they make shimming a clutch a Dream.

No the shims are for spacing the washer off the bearing. It contacts the inner race of bearing only, so you don't ride the washer across the inner and outer races. This will add friction and heat the bearing up, making it fail prematurely, just like the clutch bearings will do with full size 5x10 shims. I had a thick washer in my pit box, but basically any washer with a 5mm inner diameter and say about 2-3mm thick will do. This mod is more important when running the plastic rear brace, which a lot like to do. I actually sent a email to Losi about this center rear axle being too short. My Kyosho and Mugen are plunged way into the drivecups compared to the 8ight.

You could stack up some .3mm shims up instead if you couldn't find a washer IMO.
