It depends on what you're doing. i'm all about high speed, high acceleration street runnin' so 50K weight didn't do anything but make my front differential "diff" out constantly. it felt like i was running a loose slipper is the best way i can describe it.

i went all the way up to 350,000wt and it still wasn't doing crap for my front diff, so i started using playdough in the center and leaving the front and back at the stock weight...that got me the results i wanted.

if you're gonna be doing alot of dirt track/off-road racing, just follow what the manual says and you'll be fine. if yomu're gonna be doing alot of parking lot stuff, i recommend using putty or playdough in the center or it's gonna feel like you're just spinning your wheels with no power.

I think the trick to getting this part to set right is in how you get the bearing on the spur side to fit.. what I mean is there is play on the bearing so it moves back and forth just a little bit, if you don't get it perfect into the CNC mount and then kind of pull it out slightly and into the front mount it will not fit properly as you described. I have an 8ight-e 2.0 sitting next to me and it fits just fine using the losi kit and it doesn't rub at all. I would suggest investigating how that bearing is setting (even or not) and you will find that it will work ok for you when you install it correctly. Now I do know you can't use the plastic bearing w/ the tekno kit as the spur rubs into the bottom so you would need to cut out an even bigger spur drop which really isn't worth doing. I really wanted to swap to the plastic spur, but I decided to just hold out w/ the stock steel 48t. I absolutely love how the 8ight-e 2.0's sound w/ the plastic spur gear installed (my brother has one) :)

Still, if you get the RCM mount, you'll have zero issues with rubbing on the chassis as it raises the center diff a few mm and i don't get any rubbing on the mount from the spur either. I run 45T with no problems at all. Not only that, it's an awsome mount that allows you to gear as high or low as you want. that's one thing that no other 8ight conversion seems to offer right now.

the wheel freespin i get is crazy...no binding at all. RCM mounts rule!

Yes, the RCM mount is what I am planning to invest.

Losi's mount is so thick that I can NEVER install my pinion like the way you did in you picture.
the Losi mount's center hole is so small that most of my mod 1 pinions can not be used because they have bigger bore(the untoothed section), like this one:

Also, the RCM mount allows the motor to move horizontally when adjusting mesh, making it much easier to make a motor rear end brace.

DwightSchrute from this pic it looks like you are using the Losi motor brace, how did you make it work together with RCM mount when adjusting mesh ? the mount moves the motor horizontally but the brace supposes the motor to move in a slope according to the losi mount ?

can you run the heavy duty steel supports in the nova cups or are the spider gear axles supported in the right place?
I've got Nova bits on my maxx and they are bullet proof - hard to order from OZ though

i'm not sure i'm understanding your question. are you asking how the top brace that is over the spur gear still fits with the RCM mount?

if so, the rcm mount has a spacer that goes under the front mount so it levels out the front and rear mounts to be the same height so it really dosen't have any effect on how the motor is moved when meshing. it also raises the center diff some because the rcm mount is a bit taller than the losi mount. i hope that answered your question.

or are you referring to the black "L" shaped plastic that goes under the losi mount? if so, you don't need that piece anymore when you use the rcm mount because their taller and allow for more clearance for the gear. i have since taken them all out of my 8ights. I imagine if you used both you might manage a 48t spur, but i'm not sure.

i haven't tried the HD supports in the nova cups so i'm not sure if they would fit or not, but the cups are machined to perfectly hold the spider gear axles in place. as long as you regularly change your diff fluid, they ought to last just short of forever.

I have the Losi conversion... never one single problem with the gear rubbing... Losi has the best car and kit out there! Go Losi or go home!

Playing with fire here... Losi has good products, but I would not say they are the best available. You might be able to say that if you have owned everything out there... I will say that the rcm mounts are the best I have tried, better than the losi mount I have.

i just don't get the losi mount at all. it was a poor poor design imo. that huge bump severely limited any pinion over something like 16t or so. i even modded it so i could use bigger pinions, but even then it was severely limiting.

here's the before and after:



RCM mounts rule!

[SpEEdyBL]

If the rcm mount would allow you to keep the same center diff height as stock, requiring you to add your own spacers for spur clearance or dremel the chassis (right now it forces you to raise the diff about 5 mm from stock and the motor 5 mm higher than it needs to be) then i would reinvest! Lower CG rules! I like to have a competitive edge to my stuff!

[DwightSchrute]

on a side note:

someone at my lhs said if you're running the rcm mount you can also use the 2.0 center shaft. i might have to try one to see for myself.

Saying CG, the Losi kit raises the battery pack about 10mm higher above the chassis. you know it's the heaviest part of the buggy hanging there high..... That's another reason why I am so eagerly expecting new dedicated electric models to come.

Sorry for the confusion, English is my second language.

I was talking about the motor brace that lays underneath the motor can to support the motor body during hard landing. This component:


It is arc shaped, when you move your motor horizontally, this plastic brace will get in the way. The brace was designed for Losi's 39mm motor, thinner 36mm motors may have less problem here, but will have no support on the rear end of the motor.

Loweset CG setup on both motor mounts and battery trays is the tekno conversions.. there is nothing as good iMO.
