Project: Savage Flux 5T - RC-Monster Forums

thzero · 09:59 AM

Well I've been pondering what I want to do with this. I keep wanting to add truggy features to it, i.e. truggy diff cases (D8/D8T/etc), center diff, swapping to diff arms, etc. Not to mention the issues with fitting 8S between the rails. The above solution seems best, but I am just not content with it.

So I began to wonder why not just go with a truggy (my RC8T) to began with. The issue is I really want to run the Baja 5B tires/wheels. But there aren't any 24mm adapters; after poking around I found that Integy, yup the same, makes some extenders for "buggies" and a different couple of options; so I picked them up to see.

First is this.

However, this don't work as when the wheels are added there aren't any threads left to thread the nut on.

Second is this.

Well for my case, they were two wide so the pin wouldn't line up with the hole in the axle.

Third is this.

Ah! They work; almost... had to grind a tad off the end to get the pin to match up, not too much and not where it will seriously hamper things. They are pretty well machined and very beefy, much more so than the standard RC8T axle extensions, but its probably made of the standard crummy alloy Integy uses. The one thing I really don't like is that all that keeps the pin in, and its a standard pin through design, is a large o-ring. I should note that these come with two sets of pin holes, the 3mm for like the RC8T and a slightly smaller set; the pin holes are perpendicular to each other. So these should fit the LST/LST2/LSTXXL, most 8th scale truggies and buggies, plus probably some more. Savage not so much.

These things are wide! From the outside of the bearing to the outside of the hex, the standard RC8T axle extension is 18.75mm. These are 38.5mm. So thats a 39.5mm, 19.75 per side, of extension! Not quite sure I needed that, could use probably just 20mm. Total width, outside hex to outside hex, is 422.25mm.

Here they are in comparison to the standard RC8T axle extensions...

And here they are on the truck... need to pull it apart and get a comparison shot between the two.

Obviously these are 23mm hexes, so need some metal tape to take up the slack for use with the 24mm Baja wheels. The biggest issue is that the threaded shank is only 9.5mm as compared to the 24mm Baja hex hub which has a threaded shank of 12.5mm. So the nut won't fully thread onto the shank. As a reference, the thickness of the wheel is 4.5mm for some ProLine Tech 5 wheels as compared to 6.5mm for the ProLine Desperado wheels. Basically there is about 3.4mm of thread outside the Desperado wheel and the hex nut is 6mm thick; slight issue. Suppose I could grind down the wheel about 2mm; wouldn't be prefect but still.

Now, if I could only find someone who could machine me a set of these, about 19mm shorter, and with 24mm hubs and 12.5mm threaded shank it'd be prefect.

For reference, the pin through design for the RC8T has a pin that is 3mm diameter and 16.5mm long; not quite the 4mm that the Baja uses, but its slightly thicker and definetly longer than the standard Savage pin.

And just some shots with the 5B tires mounted...

Can u maybe provide info about the tire/ rim, front and back?

How tall are tires, what is the weight of the rear combo and front combo?
Dosent look much offset by the rims alone?

How do u like them?

They are Baja 5B tires/wheels; specifically the ProLine Badlands tires and Desperado wheels. Somewhere in this thread I believe I provided the weight. None of the wheels I've seen for the Baja 5B, I haven't looked at the truck wheels as I think those are just too big for an 8th scale platform, have any offset. But as an FYI, neither do the 3.8" Trenchers.

I like them for a large "buggy" platform because they have a low sidewall, so it drives more like you'd expect a buggy to as opposed to say a monster truck.

I have been desperately looking for an ideal tire for the savage... I wanted to maintain truggy handling... and like you said, it is important to keep the side wall low. Yes those trenchers are huge but the side wall is massive! I HATE ROLL OVERS!
i think the proline baja tyres are great! (people dont like them on heavier bajas as they wear quickly, but they should be perfect on the savage)... also with the powerful brushless systems, there isnt a worry about moving these tyres

and i believe the heavier wheel/tyre combo def gives more stability at speed...

edit

just had a re read of your entire thread! I love how you have tried to play around with the truck so much!!!
You are going the CEN arm way, and i have tried the LST Arm direction... We can compare which hubs work best with these tyres haha
What do you think?
Also with your experience with your tyres, how have you found them in corners? do they slide a little or is there so much side bite that they grip and force you to roll over?

On asphalt it does have a tendency to roll over in sharp cornering. But I attribute that to the higher CoG on both the TVP design, the higher placement of the motor in the Flux TVP design, and the batteries being over the driveshaft, and a bit with the width of the truck even with XL axles.

Offroad I've really had no issues.

Since I'm looking at turning my truggy into a 5th scale (mostly because I found myself trying to truggify the Savage so why not start with a truggy intead), I turned by Savage back into a standard sized Flux to run on 4S (for now); got one lid painted up and this how it ended up...

Some non-standard features...

TCS Crawler TVPs (until I decide what I want in custom carbon ones to fab up)
ProLine Trencher tires on Tech 5 wheels (love the look of these mounted up)
Integy rear-hubs
FLM Drag Link (http://www.fastlanemachine.net/prodd...lm48000&cat=22)
FLM Skid Brace (http://www.fastlanemachine.net/prodd...lm47500&cat=22)
Spektrum DX3S/3100R transmitter/receiver
Running 47/19 ratio (may go up to 47/20... if I want tons of speed, I can whip out the truggy)
HD Drive Gear 18-23T (102514)
Yellow springs and 50W oil
Modified steering hubs (see further up this thread)

Will be looking at swapping to using truggy-style hex hubs instead on modified XL axles. Also when I rebuild the diffs I'll swap to using the Vorza/D8 cups and HD internals.

May eventually put a 1518 (my 1520 is going in the 5th scale) with the GCM 42mm motor mount.

This is just planned to run on 2S or 3S; nothing too wild.
