What is your setup??

Right now it's all a mix of ACNCM, FASTLANE & UE parts...
I think the pin holding my 2nd gear has snapped, and I think my UE Spyder 8's are starting to slip.

I'm thinking of getting all new Fastlane parts with CEN Diffs and RCM's Center Diff. I just finished putting 2 couches inside the new hobby room. I plan on spending lot's of time this year.

I've been following a few threads and ready to spend some change...

Not sure about wheels yet, I'm looking for Aluminum bead lock rims.

As for Motor and ESC, I will drop in either my spare Castle 1717, NEU 1527, LMT 2250 HA or LMT 2280 HA. ESC maybe MGM 250A63V or another Mamba XL.
I have too many Motors and ESCs laying around, and not enough vehicles to put them into..

I have the same wheel and tire combo you have. So far the only combo where I haven't pulled the tire off the rim. Not much growth without tape but not very grippe but looks cool. MBX6T with a 1520 on 6S with a 22 tooth pinion gear.

Wow, a his & hers bathroom counter? Wicked stuff.

Truck looks good too....

Have you balanced those tires Sike? If not you will NEED to do that.

Good luck with the project. I had to give up on the maxx trucks, just too weak...

The 1717 is a beast, I ran one of them in my lst on 6s and it was crazy. I even geared it up and it was still crazy.

I would not both with a center diff, with alot of power they just unload. Does help with turning, but do you really need this monster to make tight turns.

And those stock shocks need to go. OFNA aluminum shocks fit, pretty sure the ones to use are buggy fronts? Someone help me out here.

On the tires, I did tape them to keep swelling down. Plans are to balance them, but I haven't yet.

I have found the maxx trucks to be weak also, but this is my attempt at making one that is more bullet proof.

Hybrid Bulks were in the plan, so I order Revo Spec diffs to rob the intrals from.

When I opened the Diffs, I see that Traxxas has changed the bearing sizes. The Ring side bearing is much bigger and beefier now. So the Intrals won't fit the bulks.

I've always found the Arms and the Shock Towers to be the weak. Thus RPM replacements for those.

Yes, I agree. The Stock shocks need to go. They are on the list for replacement.

I've been debating on motor choice.

Linc, remember that 36-60-1500kv Medusa motor that I got from you?

How would that work in this? Gear it for about 50mph and put it on 8S?

PS............How's things been treating you there in Slidell?

The 36/60 would be too small, that is a good buggy motor, IMO. The big wheels and tires will put too much load on it, plus i doubt this truck will be light.

The hybrid bulks use ofna or similar diffs.

Rpm arms and towers are a good idea, especially if you are using al bulks.

I think truggy front shocks would be the way to go, need something around 4 inches long if memory serves me correctly.

Slidell is fine, pissing down rain right now. Still working on all of my projects, save for rc...

I keep thinking about the entire "HV" craze when things stepped up to a massive 16.8 volts. LOL

Watts = amps x volts

Watts is the measure of total horsepower. It is Total Amp draw that makes or breaks a motors efficiency.

I want to try the 36-60 in this on 8S.

I remember this motor on 4S and it snapped 4 of the Traxxas Drive Shafts in about 8 runs. Alot of Torque.

I also remember running 2 - 4S 4000mah packs using a parallel adapter feeding a MMM Esc.

One day I accidently grabbed a series adapter.........the ESC armed and away we went.

Geared something silly, like 22/40, I seen the truck do a backflip at about 30mph when I grabbed WOT.

The setup survived. LOL Of course, I stopped the run, realizing what I had done.

Revo spec diffs won't work in the Hybrid bulks, you need real 1/8 scale diff ( Ofna, hotbodies, LST2 ) internals.

1/8 buggy front shocks would work well, though I'm not sure how much adjust ability you would have with the RPM suspension & fixed shock towers ( only one mounting point )- buggy shocks for slammed suspension, truggy for off-roading / jacked up suspension.

Ok. Maybe these aren't hybrid bulks.

I fit the intrals of one of the older revo spec diffs, and it fit just fine.

It has the smaller bearings, but I wanted brand new stuff.

Hmmmm..............

Sounds like you have the Combo bulks..

sikeston34m · 03.25.2012, 12:42 PM

Well FLM included the wrong drive cups in the chassis package that have a 5mm ID. They won't fit the 6mm transmission output shaft.

So..........while they get that mess straightened out, there is time to play around with other ideas.

The main idea is to keep this truck low, with the center of gravity as low as possible.

One thing that helps stability, is the overall length and width of the truck.

I added wheel extenders to the setup which increases width by around 3 inches.

How durable will they be? hmmm..........we'll see. Thoughts?

RC toy · 03.25.2012, 01:48 PM

Such wide extenders with stock hubs... You will blow your bearings on the first run.

_paralyzed_ · 03.26.2012, 09:55 AM

extenders are for shelf queens, just an all around bad idea otherwise

Why do you say that Harold?

I tend to aggree with RC Toy though. Aluminum Knuckles aren't a bad idea.

The hub of a wheel is centered over the knuckle for a reason. It keeps all of the force on the bearings rotational. Offset wheels are a better idea.

The extenders act just like levers putting unwanted stress on the bearings.

Additionally, the length from the knuckle exaggerates any wheel imbalance.

It's just not the ideal way to widen a truck.
