HB D8T By Sir Slide Alot.

building a D8T Brushless.

battery box from RC-Monster

CBRacing is likely going to import the EliteRC motor mount you will see in the pictures further down.

This futures a block that bolts to the motor and slides into the mount on the car.

One screw into the block, easy access for adjusting gear mesh and changing pinions.

Offcourse the car is powered by Castle MMM V3 and NeuCastle 2200.

juice provided by Hyperion G3 5500 35C 4S lipo's.


















Got R Done!!!












Fan on motor, from 55°C to 45°C.




Major update:













Pretty low C.O.G.

Hello,
great a tread for your D8T brushless !

I can see just one picture .

I only posted 1, this show the center diff clearence.

it is only 3mm and the slipperdiff is way to fat to work here.

any idea's?

lenght wise its fine.

EDIT, put more pics on original post.

Thanks for the new pictures, you will probably have to make some holes to mount the slipperential and make a new top plate.

This car has a cup holder.

also, i tried yesterday mounting without top plate and it also hits the corner of the radio box.
but the backsection of that still has to be hacked, so i'll see.

It's seems complicated , I'll notice the slipperential cant' be mounted on a D8, it's probably the same on the buggy.

Yes, D8 and D8T are made exactly the same in the center.

it's a bit difficult. it will go in the RC8T.

picking up you motor mount tomorrow at the post office.

You are fast

Yes I do my best to be fast .

Seeing how i hate the losi battery tray in goes a proper one.

can you tell me the size in the picture?

Hi,
I have verified on the ones I have, I have 1,9 cm.
Your order was shipped yesterday .

Nice, i'll go see where that brings me.

Edit, it should fit easy, if my measurement is good.

I think it will arrive on monday .

likely, but usually no one home so the postman take's it to the postoffice.

Hi,
thanks for the new pictures, great car , is the D8T lighter than the RC8T?
We want a video !!

Update. :gni:

Great , tell us you feelings compared to the RC8T .

Good:

Handles better.
Easier to work on.
Better quality.

Bad:

Overpriced in Europe.
ugly roof on body.

Thanks for your feedback .

No problem, here some more.

Runtime on the field with CC 2200, Hyperion 5500 4S and mostly flat-out driving 12 minutes to 14V cut-off.

temps where no problem at all but offcourse it isn't very warm anymore, i think around 15°C.

Now the Truggy has about 2H runtime on it and nothing is wearing at an alarming rate other the the front-center cvd.

but that seem to be the one part on my other truggy that wears most aswell.

All in all very satisfied with the D8T.

Good news , for the cut off you could set it at 13V, it's safe enough .

Hi, Sir Slide Alot.
I'm on the way to make my D8T a brushless truggy, i've ordered the motor mount for the D8 by CBR.
And i'm wondering what pinion should i use with the MMM v3 2200kv and 4S lipo to get good performances and run times ?
About the front center CVD of the D8T, i've experienced some troubles with the screw that holds the CVD to the front diff, and solved the problem by adding Hard Threadlock on it, and after 10L of nitro with a powerful engine, it seems to be still in good conditions.
I'll see with the Brushless motor.
Thanks Alot.

14T is very nice. 13T is slow. haven't tried 15T yet.

Salut,
perso je te suggère entre 14 et 16 dents en fonction de la piste et des températures moteur / contrôleur.
Forcément, l'autonomie sera meilleure avec 14 dents.

Edit : Sir slide a lot m'a devancé .

Thanks for the fast replies....

Hi Sir Slide Alot, i've checked my front center drive shaft, and you were right !
It is wearing out very quickly !!!
In order to change my center cvd, i've ordered the optional one from hpi/hotbodies, ref : 67217.
This one seems to "smoothes out the harsh angle", in order to avoid the very fast wearing of the original one !!!!

Traduction :

Sur le D8T Hot Bodies il est vrai que comme le disais Sir Slide Alot, le cardan central avant s'use très vite.
J'ai vérifié le mien, après 7 litres il est très usé.
Afin de le remplacer j'ai commandé le cardan option de Hpi/Hotbodies ref : 67217.
Celui ci a l'air de rendre l'angle de liaison avec le diff avant moins important, ce qui réduit d'autant l'usure de celui-ci.
Alors, possesseurs de D8T --> Option Obligatoire

Hot bodies 67217

When mine is gone i'll replace with Kyosho MP9 front shaft.

ST-RR wheel axle work too, i'll fit those aswell.

Hi,
thanks for the new pictures int he first post , very beautyfull motor mount.

They will arrive at CBRacing soon .

regaring the pinion gears i had falling of, your suggestion works.

Also mods that can be seen in the pics are a associated spur gear on the HB diff.

it was modified in a lathe to fit over the diff cup, as the HB is 1mm fatter then Associated's diff.

And a custom topplate for clearence on the wider spur.

Painted the rear mudguards aswell with flat black.

Excellent Mods again Sir Slide Alot!!!
Your D8t transmission, pinion:spur, must be silent now ?
What is precisely the reference of the associated spur you used ?
I've posted the pics of my D8T conversion, that was inspired by your's: My D8t Electric

Excellent Modifs encore, Sir Slide Alot!!!
Ta transmission de D8T, pinion:couronne, doit être silencieuse maintenant ?
Quelle est la reference précise de la couronne associated que tu as utilisé ?
J'ai posté les photos de la conversion de mon D8T, qui à été inspirée par la tienne : Mon D8t Electrique

Less loud, but silent no.

i think mod 1 is to big to be like 1/10th scale, usually cant hear those at all.

89521
e-Conversion Plastic Spur Gear, 50T

that is the gear, but be warned it takes modification with lathe, otherwise it will not fit.

Hello,
Happy to see you finally fixed your pinion .

Your 50T spur isn't bigger than the stock one?

La couronne plastique ça réduit un peu le bruit mais c'est pas forcément la solution miracle, l'aimantation des moteurs type Neu y est aussi pour beaucoup.

It is the same size.

but the teeth are twice as wide.

Sir Slide Alot a écrit:It is the same size.

but the teeth are twice as wide.

Good .

PS : I chose you a new avatar .

i dont remember the old one.

it was from Hyperion right?

i tore the D8T all apart, working on something.

Yes your old avatar was Hypérion G3 .

What are you preparing?

My own chassis.

i have my cardboard prototype ready now.

Not sure where i'm gonna end up.

Hi, Sir Slide Alot,
Today i broke the top plate that holds the center diff of my D8T.
And i was wondering, where did you find yours, i mean the X plate you put on it ?
I've changed my shock springs for the orange, like yours, and now it doesn't hit the ground on each jump, and the chassis seems more reactive than before.
It Was another great tip from Sir Slide Alot
Keep on going this way, and thanks for all.
