Right there's plenty if threads kicking around on here all ready , but there's bashers and racers

This is my micro build thread
For racing

I will be competing this year in the wrca and brca micro indoors

I have owned a shark up untill now and swore buy it . This has now gone to a new member at my local club
The car was supereb and set up a treat

I have been a proud owner of the mini 8 just over a week

My initial idea was wait till it's out , wait for people's set ups and wait for a go

As I own a 2.0 1/8 nitro i know Losi make a good car , parts are everywere and good priced

So I thought go for it ! Lrp shark bits are impossible to get hold off never or less my boxes of spares they will run dry one day

On first thoughts the buggy was heavy but looked excellent build quality

Standing next to the shark it looked similar in dimensions but the shark was made to just look like a toy ha ha

Mini 8 unboxed

It wasn't long untill I stuck a set of new Yellow pins on her

I then tried the stock nimh battery

Washout, disapointment

Out came the soldering iron and deans and on went my lipos

Booooooom
Result . Now were talking

A few mods to battery tray , a few new hes in chassis and a moved esc and car was wicked

After 2 mins I lost power to front wheels

The Losi factory failed to use loctite to secure the grub nut on drive shaft to the carrier to box

Easy fix though and did the rear the same time

The shocks were next
It was like a trampoline

There was hardly and oil in them
I first opted for 40wt oil all round as I ran this in my shark

Here's a vid to show the difference in fronts done to rear

This night I raced it first time in prep for the wrca
I found it a good car , lots of understeer to be true
Twitchy and a light rear end, this contributed to my understeer

Back at home I changed the rear shocks to 30wt oil
Also at this time I moved the shock positions on tower to inner and bottom to outer
This was front and rear

Also I lowered the car so the shafts were level
After this I dropped the rear slightly lower

I worked the camber to neg 2 on front and neg 3 on rear

They were all over the place out the box
Also I have rpm
Ball caps on order now as these pop off for fun
!!!!!!!

Here's some pics so far

I used my shark goblin shell

Next to my shark, swapped shells to

I'm currently using totally stock electrics other than the inolab servo

I have changed the slipper , ie tightend it 1/8th of a turn

Running + 10% punch

Ohhh and used a bit of fuel tube in front shocks to stop them locking out as the shafts are a bit tight on the front on full compression( drive shafts )

I also stocked up on some spares

2 of everything practically. Ha ha

Here's a vid of us running at our wrca last Sunday



I'm
Not really sure what I'm going to do next
But I can promise you that thus will be one of many set ups

The cars new so don't know what's strong what's week whats good what's bad lol

Any advice is gratefull and any questions I will try my best to answer

I should have added

In
Using rhino 1010 mah 40 c burst lipos
They have nice thick gauge wire
Also using
1300mah 35 c burst storm batts

The rhino are my Batt of choice thou as they are excellent value for money and give really good punch

I also have the stock nimh if any one wants to give me something for it .


I will be trying out my White rally blocks next time at track

I also forgot to mention, I'm experimenting with some weights at rear


Also I just had some awsome graphics emailed back to me for my pit box stickers and shell stickers

They fall online great with my shell
Bit Girly but impact will bd great

What you think ???

Can't waitt to get them fitted now

Right after a lot of thought and also in readiness for next weeks racing

I've decided To strip the front gear box and fill with standard grease

As these have differentials geard boxes and not seald like the 1/8 set up you cannot use weighted oil

What I will be using is the kit grease from my old rc18

I will take pictures of this in steps

The aim of this is better powering out of corners , and eliminating twitching . It will deliver more power to front when needed and balanced power

After a great day racing today

I came home and made a steel plate to strengthen the front hinge pin holders

I have a set , now minus the front as I gave one to a mate as he killed his I'm 1st heat

As I no longer currently have a spare front untill he gets his I strenghend mine

It's only a temp measure until the alloy ones get released in uk

Here's what I done

The wholes are oversized for play to avoid being to tight that will effect drop and suspension wish bone return and also will weaken the rear plate



Posted Image

We will see how this goes next week

In regards to the day the diff mid barley helped

Tonight I'm going for 100k Durango shock oil sod it !!!
I've seen it done and works a treat

The wing seems nice

I went for White rally blocks my old favourite but just couldn't get on with them
So returned to my dreamy pins

I will continue to use blocks but just couldn't today, they didn't agree with track in my opinion

I've left the rest if the set up as week before and really started getting used To car
I betterd my average time and fastest lap over last two times using buggy so happy

Also I beat the boy I sold my shark to and come 3rd in the b final
For myself this us extremely well considering its 2nd time out with car realistically
Now used it approx 50 mins max

Will post the new front diff rebuild again in a bit

I think you need a new set of drill bits !! stick em on the Santa list !!!! next time try using a punch and drill nice and slow and on to a block of wood that should help out a bit better then you'd get a nice clean hole and in the centre hope that helps you out. was you on carpet as there looks like a lot of fibre on your dog-bones someone once told me to use wd40 helps stop it from sticking to them never tried it myself but thought id pass it on

Lol , they are new drill bits
It's steel sheet , had night mare drilling it

It's only a temp measue to stop the front plastic hinge pin splitting
It's not seen so not to bothered on cosmetic appearance at moment as I've orderd my alloy ones

The thing is it works so I'm happy ;) but thanks for heads up

Btw , yeah . We run a carpet track of course . Mixed with shiny surface here and there

Also rebuilt the front diff as I said I would

What a messy job, the oil smt lush though
Posted Image

It's 100k diff oil. Like glue. Silicone stuff

Front diff feels nice and tight now. Should help
