Default GCM racing and Platinum RC Products introduce the RB2

Well Gentlemen I have been given an oppurtunity to build and race an RB2 carbon edition. Its really a meeting of the minds here having Platinum RC Products and GCM Racing coming together.

This is an e-savage based platform. that stretches the chassis 4cm's.

This chassis is the offspring of candy and sex. It's just that nice.
It's a very nicely cut piece of carbon fibre. There were no loose strands or off center holes. The chassis went on to my bulkheads like they have done it before.

So I will start with a few pictures to show the setup these guys are giving you.

I have been using the original roadboy chassis in black. I loved it, and it has seen some real abuse. and is still straight as an arrow. Here you can see it pictured beside the Culmination Edition.

Note the thousands of pre-drilled holes for mounting hardware. More on that later




I installed a set of the GCM V2 diffs. These remove all the slop from the output pinion and they look very very nice.



It's a shame the beautiful red is hidden inside the diff case.......
GCM has also made revisions to the original RacerEx arm. Here
you can see the first design pictured next to the new. There appears to be more flex in the new design as well as considerable weight savings..

There are many many holes for mounting the tranny either in the stock position or having it reversed.

The kit includes dogbones that are for a nitro savage 18ss. You can either use traxxas 5mm t-maxx diff cups or Ofna 9.5 series. You can also find your own dogbones and make a setup that you think works best for you.

For example any savage dogbone will fit these cups as well as any 9.5 series ofna dogbone. There are literally a few dozen combinations you could have.

Here is a few pictures of the tranny mounted between the plates




I like the look of the traxxas cups, but the ofnas are of better quality I believe.



If you remove the stock ESC holder from the chassis brace, it makes an excellent mount, and of course there are holes to mount the new plate lower on the chassis. This will lower the center of gravity aswell....

Like I said earlier, when you have two smart guys working together your bound to have something great. it's inevitable.

aswell as how nice everything fits together.

I will be racing this in the MT class during the outdoor season. With 10 minute mains my 5000mah lipos will survive and be charged between heats.

It should be exciting and hopefully put a challenge to the revo dominance of this class.

I will post some more pictures of the truck later today when I mount my receiver.


feel free to ask any questions or air out any comments/concerns.

cheers

Default RE: GCM racing and Platinum RC Products introduce the RB2

heres some information about the parts. mostly weight and warranty info.

straight from their websites.

The arms are surprisingly strong with the engineered stress relief and ultra-lightweight. Infact the upper arm weights only 15grams and the lower arms only 40 grams each.
We do not recommend RacerEX for trucks with a running weight over 4.4kg.
All RacerEX suspension arms are heat treated by a boiling process. This greatly strengthens the arms and avoids the snapping plastic problem that is common to machined plastic parts.
Designed as a racing arm for track conditions



TWINv2 Diffs:

Includes 2 new planet gears, a new planet shaft, one anodized aluminum diff case, shims, and 4 2-56 machine screws for mounting.
Weight is a few grams only over stock plastic case and internals. New solid billet case and new planets are the single answer to failed stock E-Savage diffs.
We are recommending using heavy grease.
If the case or the planet gears fail, simply mail them back to GCM and we will send you replacements at no charge.
Carbon Fiber 4mm RB2 Chassis plates:

Designed and supported only through GCM Racing. Full 4mm fibreweave carbon chassis plates sold only through Platinum Products, the chassis manufacturer. PRC also sells matching HD center dogbone kit.

Reversible gearbox mounting from 79mm motor spacing to unlimited in the rear.
Mounts TwinForce trays directly, or straps or custom skidplate trays.
Has mounting holes for the future Jedi-E motor mount.
142 grams set, our BL custom tray chassis is 184 in aluminum and carbon plates are 33% thicker.


just awesome in my opinion

very nice built. i like some of the gcm stuff really well. especially the diffs.
i will however never understand that people spend much money to make a monster truck look like a "quasi truggy" whereas they could have bought a real racer truggy to begin with which would most probably even perform "better" on a track. but to each his own. [8D]

bye

ps: the most needed part for e savage, namely stock length cvd were never produced by gcm or am i missing something?

Hey....I feel like I've seen this before.

GCM makes solid stuff, with great customer support. I like how they'll replace a failed diff if it happens.

well i didnt spend much money makin it a quasi truggy like you think. $20 in shock towers isnt really that expensive. neither was using a spare wing mount from a buggy and an $8 wing.


This vehicle was purchased as a basher vehicle and remained so for well over a year. but then i took it to a track..... it didnt perform very well so the modifications began.

also, just so your aware, they actually have MT classes at most race tracks. which means monster truck, not truggy or buggy, but monster truck. but to each his own right

yeah those mt classes are sure fun. i thought of it more like a "fun class". however if the rules allow for such heavy modifications like you showed above it seems to be more "serious" (as far as a hobby can be seroius :-). it then makes sure sense to modifiy the monsters. but then this "upgrade spiral" starts you know because a standard monster which was originally not constructed for trackuse will not be able to compete.
anyway ... who cares. as long as its fun all is fine.

Freakin Sweet!!!

I think theres a specific savage mod that uses the LST shocks though, the 1/8 buggy ones should be perfect but just fyi

rhyslar the mods are pretty simple to be honest. nothing very complex at all. i have a 2wd stadium truck i race aswell. and this is fun without dumping $700 on a new truggy.
might wanna take a gander at this here man...........
http://e-savage.com/forums/showthread.php?t=1822&page=2



rcdude. i was running LST shocks for a very long time actually. all you need is a small spacer to move the shock rod end away from the upper arm. its a great mod and with 25wt oil in those shocks the truck was a great basher.

2 words....... FRIGGIN AWESOME!!!!!!

That has got to be the coolest E-Savage I have ever seen! Great build!

What made you ditch the LST shocks? I have OFNA shocks on my Maxx and they are great, but I have also heard nothing but good things about the LST shocks so I am wondering why you switched?

I ditched the LST shocks because of weight and to lower my center of gravity.

however, in all honesty i liked the way the truck handled better than with the ofna shocks i have now.

i need to spend some time tuning, and if i'm not happy i will install the LST shocks again.

i didn't say its complex. you just turned a nice little basher into something like a truggy by changing tvp, wishbones, adding a wing, new shock towers etc. that seems to me "heavily modified" eventhough it was pretty easy to build i agree.

yeah i know this site.

imo those ofna shocks fit pretty well this car from any aspect. i do not see any advantages installing the heavy fat lst shocks there.

well the truck performed flawlessly at the track. it is very very competitive with revos now and if i was a better driver there would have been better results.

need to spend some more time tuning, but heres a video of the a-main this past sunday.

I would also like to add that any 1/8 size body will fit very well on this chassis.

I am currently running a hyper8 ST body, and it looks fantastic.
This chassis really makes the e-savage a competitive racer.

if you don't want to run a traxxas revo, I would get this chassis and add some flavour to the MT class in your area.

well i have raced this truck now in the Canadian Offroad Championship series here in BC.  and I finished in 4th out of 11.  This was the only NON REVO based platform.

to finish 4th as a ROOKIE driver and against race designed moster trucks really shows how well this truck handles.

if anyone races monster trucks, you need to take a look at this chassis so you can bring something different to the monster truck class at your track.

very light and nimble on 3s with enough power to chase down a big block revo.

I love this truck.
