So how exactly do you go about deciding that you need a different diff oil? Just curious. I've heard others talk about it. In bigger vehicles, you choose your oils mostly based on the amibient temps you run in, and how severe duty you need (ie., I tow with my truck, so I run a severe duty oil).

How does this relate to an extremely small vehicle, that runs for 15 minutes at a time?

Thank you Squirrel! Here's a recent pic, just for you :)

JThiessen, finding the perfect diff oils is always a trade off. In RC it pretty much all depends on the amount of grip your area/track offers. Basically, I want them as stiff as possible, without spinning out under hard acceleration, but not to light as it would unwind on the wheel with less traction. See? Hard to explain for me.
For example in the center, too stiff would even give you wheelies, and too soft would only result in balooning front wheels with no acceleration.
Front-to-rear ratio depends on driving style: DO you want the most traction in turns, or do you like to drift through them, or do you only want to swing its rear, etc...
Hope this helps. Playing with 8th scale buggies gives you a good feel for it.

Diff oil in a rc does different than diff oil in a 1:1.
Diff oil in a 1;1 lubricates the enter rear end axle bearings and all.
Diff oil in a rc acts more like a lubricate just for the spyder gears.
It adds resistance in between the spyder gears.
The thicker the oil the more resistance you have.
The thickness would depend on alot. Weight, tire, traction, driving style, and few others.
The oil has to be based by you. Kind of a trial and error thing.

Yeah, I agree with Coolhand. In RC it really is a way to partially lock your diffs.

Check Mikes nice and simple guidelines:

Well that all made it clear as mud!

It would be nice if it were easier to pull the diffs to change it, so that its easier to compare viscosities.

I've got an extra Revo, so maybe I'll pull the diffs on it and fill it with one extreme and at least I can get a better feel for how it changes things.

I'm a basher not a racer: I kind of like to be able to spin the tires. I get really frustrated with too much traction/speed in cornering and rolling the truck (this is probably due to driving experience - I bought my first RC exactly 13 months ago).

any updates and weight of the truck?

Without batts, but with 40 series wheels n'tires, a bit less than 4kg. I'd say 3.8 or so.
I learned that everything below is almost too light, especially when you use Lipo. Light trucks spin out very easy in close battles on a track, and I just like the feel of a 5kg RTR BL MT. Just my taste, I guess.

Agreed, mine is about 12 pounds (almost 6kg) and i like it for stability

this forum has me wondering on starting another project after seeing these sick picks of all these trucks gotta get a truggu or revo now,what an awesome display of showing off!!!

I am thinking about selling some parts off this truck. Figured some of you guys might be interested. PM me with what you'd like to get. I also have some replicas of the custom parts now.

Dafni

This is kind of surprising Daniel.

What are you planning on selling and what are you getting back?

interested in the mount and diff Daf, PM me and we can chat.

daff! ygpm!!!!

come on guys, get them while you can.
Daf's work is first class, you won't be disapointed. I love mine :004:

dafni, YGPM

Just wondering, why do you have the Emaxx servo plate on there? Did you have to drill new holes for the shock mounts?

Also, is that just a standard 1/8 buggy center diff with a revo spur gear in there? If so, what gearing did you use?

I threw Maxx plates on there because my G2R plates were busy elsewhere :) It's just for the pics, though. The driveshafts match the G2R.

It's a HotBodies Diff with a Kyosho spur.

Thank you
Daf

wow daf thats incredible now i realy hate the people for mowing over my off road track lol very nice work

Wow, that revo is a work of art! Is there any more updates with this beast? After reading this thread, I might have to look into a G2R revo.

-Brad

yeah! quite some updates!!!! and NICE ones too.. perhaps Daf can elaborate a bit more..

Updates? Since those ancient pics? Hell yeah! Truck has got a MAJOR make-over!

Do you really want me to spill the beans here? :)

Yep! Without a doubt!!

Spill some beans to lay next to that steak.. :p

Don't make me come over there!! :031: lol :005:

Pleeeease show us. :027:

we might be cummin for a few days tho:005: :005:

I don't know if you should yet daf. I have a good idea on them upgrades. :)

LOL! you guys are welcome..

We're waiting! :):018:

yeah im excited!

did you make these yourself are do you have them made?
i dont mean the chassis.
thanks, mike.

they are home grown.. :p Dafni has got some cool machines at the university.

sweet, he can actually do that?
i gotta meet this man.
road trip!!!!!!!

lol, lets all stop by amsterdam!

to go from roeselare (thats where i live) to switzerland you dont go trough the netherlands. roflol.

At least you can drive to see him. I wish it was that easy for me. I would be knocking on his and renes door one day. :)

actually, i cant. my dad wouldnt trust me.

You are more than welcome here Leroy..

I think DAF is going to try and make it to this years RCM Bash. What about you Rene?

I hope to be in better shape to make it this year myself. Kind of sucked last
year being wounded.
