TT02B or not TT02B : a TT02BR Build

[matisse 1626]

 

TT02B, or not TT02B, that is the question:

Whether 'tis nobler in the mind to suffer

The Hop-Up’s and pay an outrageous fortune,

Or to modify against a sea of doubters

And by opposing end them

[droidy 91]

Feed it bearings, super glue or cable tie the servo saver, crank up a garish paint job and then you're good to go. Really doesn't need anything else.

Tires suitable for your terrain are a consumable.

Fancy electronics are a luxury.

Shiny bits are shiny but you'll be too scared$$ to have fun.

You sir do not know me or have missed my previous builds, and so I say well come and well met friend!

For this will be a journey of a multiplicity of  Hop Ups, many shiney, none blue.

buckle up buttercup, this is gonna be fun.

[matisse 1626]

An exhaustive and somewhat complete inventory of Hop-Ups purchased for the TT-02B : 

1 x TT-02BR 

2 x 22065 TT-02 Type SRX  aluminium gear box joint

1 x 53141 Lightweight King Pin Set

1 x 54820 TT-02B Stainless steel shaft and support bridge

1 x 54967 TT-02 Type S steel adjustable suspension mount

1 x 53301 TL-01 Stainless steel suspension shaft set

1 x 54028 TRF Buggy aeration oil filled damper set

1 x 53576 TRF Damper oil seal

1 x 42214 Damper X Rings (50 durometer)

1 x 53585 3mm shim set

1 x 51581 Buggy rear dish wheels

1 x 51580 4wd Buggy front dish wheels

as you might expect I’ve other parts in mind and a few potential mods to try, but this will do for the moment. The unneeded parts from the kit will be sold to help fund these hop-ups, as always.

Looking forward to this. I've been considering doing something similar myself.

Are you racing this or just for fun?

[Juls1 1718]

Very nearly done this myself. Stumbling block is making the xv02 slipper clutch fit 

there is a few complications, largest being getting slightly bigger bearing to fit the stock chassis, fibrelite make a mount to do away with the gear cover which helps. Gonna have to try though.

Thinking the same exact same thing, I’m it could be made to fit in some way although ive not looked into the bearing sizes. 
 

what do we need to make fit?

I think the biggest issue initially is that the output shaft to the main driveshaft is 8mm this in itself is only an issue because I’m not aware of any 8x11 bearings. 8x12 yes. But not 8x11. That being said I’m not entirely certain the drive gear will fit, but it looks at least from photos and specs that it may be possible. 

[matisse 1626]

It has arrived!!

Inside its the usual mish mash of bags, including some truly wild decisions…

 

Everything that you see that is Blue, will of course not be blue by the end of this build. 

 

This is Bag B, hold tight for some questionable packing choices. I mean to start with why is that rear hub all in its own? I wanna know what it did to be ostracised in this way….….

 

ahhh yes, shock bodies, turnbuckle ends and a single rear hub. Makes total sense.

 

The classic Tamiya “Shaft bag” at least there is precedence for this even if it is silly.

 

Here’s a bag full of Damper parts…..and some random sponge tape…

on the plus side though, TRF X-Rings! A nice little upgrade over the stock TT-02 alloy damper set that wasn’t listed on the parts list iirc. I will of course not be using them. Lol

[toyolien 5908]

Subscribed. Just bought the TT-02 SRX but kinda wishing I'd have gone with this instead...

Could you ream the hole to 12mm and use an 8x12 bearing with a flanged outer race to locate it?

This seems like a sensible plan

[matisse 1626]

 

soon all of this will be silver, and I will be happy.

[matisse 1626]

So, its looks like @wtcc5 had basically stolen my thunder and already produced a great build with very similar upgrades…maybe i should just stop now, i mean whats the point….?

PSYCHE! As if I’d deprive you of the entertainment…:)

Anywho, potential slipper mod aside there are two things that i beed to decide on quite soon, body and hubs.

For the body the 501X shell @wtcc5 is using looks great, but id had my eye on the 502X given I’ve always been partial that JConcepts Illuzion type styling. So go for that or stick with the Neo Scorcher?

Hubs is a more interesting one as we have the potential here to remedy a lack of kickup by adding caster. My thought is to use DB01/XV02 caster blocks and uprights, that is if they fit in the arms. 
 

Does anyone have a DB01/XV02 hub they could measure for me?

 

[wtcc5 5758]

Noo, please! Don’t say that. Yes, we could have made one thread with both builds in it and yes, we both have a giant nail in our heads regarding TT02… but yours will be a different style. Silver aluminum and 502 body will give it a whole different aura. And I (need to be selfish) want to see your build and result. So you need to continue for the fans 

[matisse 1626]

 

amazing what you can do with some drain cleaner and Autosol

[matisse 1626]

Seems like everyone has decided to delay shipping things to me, PJ sat on my order for a week before dispatching it, sigh.

Anywho, the delay starting of course meant the inevitable happened, I ordered more things….

ABEC5 bearings are on the way from RCBearings.co.uk and I just took the plunge and ordered a new front hub system….

DB01 caster blocks (10deg) with DB01 uprights and M05 low friction king pins. Fingers crossed it fits….

oh, and these arrived.

[matisse 1626]

I may or may not have ordered more hop-ups….

 

[wtcc5 5758]

That is the way! All in or nothing 

[matisse 1626]

Little prep work today in anticipation of parts arriving in a flurry during the week ahead, which is convenient as im away in Germany….

anyway, tapped the screw holes on the chassis and gear covers.

 

And then decided to add to my list of “small things in a build that will make zero difference to how the car runs but are pleasing anyway” 

Yes, I sanded off all the burrs left from the sprues so the diff gears are nice and smooth on the edges. Totally pointless, very pleasing. BTW can recommend 3M professional 400grit paper, the non-slip backing is great. 
 

 

 

[matisse 1626]

Good post day. 

ABEC5 bearings, because smooth is better.

Also a whole load of other stuff that you’ll be introduced as we go through the build, but here’s some of it.

Whilst i was fettling last night I got to thinking about how many different variations of plastic there are in this kit. It’s fascinating how the different formulations of ABS and PA-GF have been chosen for their individual material properties.

For instance, the chassis, gear casings/bevels and Diff internals are technically PA-GF, so a Polymide with glass fibre inclusions, yet its clear that there are all different recipes chosen for different reasons.

Believe or not, but I sanded all parts from sprues...

This isn't Schrodingers experiment; we KNOW you bought more hopups.

Do you have list, how many of each type bearings are required?
