Lipo narrow chassis

brand new concept lipo chassis,

flipped trasmission , centered electronics and outside lipo position

fully balanced without additional weight

Milling.......

Thanks to my friend Mario and his powerful CNC milling machine............

new lipo chassis is coming!!!

Yokomo on the blocks....

after a while.....my new project, a rally bashing car.......so:

Yokomo CGM chassis: i've cutted the downstop wings to have better downtravel, raised up the suspension blocks and longer damper ends.

Electronics: Team Wave rb30 esc, ko fast servo,lrp phaser receiver and an old novak 10.5 ss pro

Tire and Wheels are from tamiya: rally blocks on ford focus rims (the only rims found at lhs)

Body: Tamiya Lancia Delta......

Missing: Tamiya lancia delta rims, Tamiya rally cockpit and maybe a light kit...........stay tuned.

Thanks Masami...

After some rumors on the net, the "legend" of rc racing Masami Hirosaka has announced his retirement from the race events........

Good luck to Masami for his  work as team manager of the new yokomo team project and developer of new products.......

Shock Towers....update

I've received first shock towers....very cool machined and super stiff carbon fiber......a "must have"

 

BD5 exploded diagram

Shane's Bd...cool mods!!!

Cool BD mods by new zealand driver Shane....the most are on the front :

team corally bones on rayspeed axles

titanium racing front spool modded with cutted slaves and yokomo alu retainer ring 

chattering free cvd 

direct steering with long turnbuckles

thanks to shane for sharing this mods....i 'll adopt them on my bd!!

BD5 new officil pics

Hi to all

team yokomo has published new official pics of BD5

Shock towers...harder and lower

These new shock towers are disigned for foam tires, the shock mounting holes are lowered by 2mm....i've planned to make them from hard 4mm carbon fiber to have the best stiffness .

avaible soon ...if interested please drop me an email to :  yokomo.fan@gmail.com

Basic foams setup sheet

This is only the starting point for the test i've made yesterday on the new 3mm chassis....

on shock building :

i've used black diafram on top of the shock, without orings or foam pieces to have zero rebound .

have used 37 foams front and rear , trinity tire tweak on the rears

very short tecnical track so geared the 4.5T 85-18

front anti roll bar : copper 1.5mm?

rear anti roll bar: 1mm ....also tried no roll bar front and rear and the car was still good

front suspension spacers on front are 4mm (not 3...)

LRP TC spec setted on 4° race program (soft...) 

timing on motor 0°

lipo foam's spec lower deck ...first impressions

Chasiss has arrived.....it has very sharp and clear edges , good carbon fibre.....thanks to fibre lyte uk for the nice work.

i've made some balancing holes on the chassis for better add weight on the car....also have made a lexan lipo retainer ......the car is well balanced with "only" 40g of Pb as you can see from the last picture it stays on two screws firmly......

First track test was really good!!! the car is awesome to drive, better turning stability and very reactive.......i've tried 37 shore foams both front and rear , with trinity tire tweak only on the rear tires.

I was really impressed by the fastest lap time ......now i 've to work on setup to make it better.

soon i'll post my foam's setup here.

Milled motor mount !!

Easy balancing 

blue is better!!!!!

World economic crisis? make it cheaper :-D

This is a 5 cent lipo retainer for my SDW car.....very cheap and very easy to make from 0.8mm thick lexan sheet....i've used a light machine and a cutter to make it....

Some lipo retainers will add stiffness to the chassis...this one doesn't change original chassis stiffness, so i would prefer it to the carbon fiber one.

on yoko BD looks very clean:

Finally some news...Yokomo BD5

FROM YOKOMO JAPAN:

Belt drive 4WD

- Four-wheel independent double wishbone suspension
- New design mass aluminum oil damper
- 2.5 mm thickness carbon fiber chassis
- 2.0mm thickness symmetric shape carbon top deck
- 3.5mm carbon shock tower front and rear
- Front one way
- Fron and Rear sway bars
- Titanium turnbuckle
- Strong body post
- Front and rear aluminum machined bulk head
- rear and front ??
- Aluminum machined steering plate
- New design universal drive shaft

in this spy shot you can see similar layout car, but different shock towers....:

These are old photo found on the net ....the car looks close to this but revised in some areas :

Carbon Bumper (3mm)

Avaible soon ......

Lipo chassis.....why not?

I'm working on a new design lipo spec chassis.

The project is based on a symmetrical drawing to alow same stiffnes on both side......more details very soon.....stay tuned:

Different Materials lipo holder for better balance Left-Right

For better balancing weights left/right side and front /rear i'm thinking to adopt a modulae brass lipo brackets:

Balncing test made using 3Dsmax Reactor :

45g lipo rear bracket and 12g on front seems to be a good starting point to have a nice balance.

Final revision: the rear lipo bracket could take some fixed weights to alow a fully , simple, balancing method....now the cahssis has 4 additional holes on the both longitudinal and crossing axes to make fine balancing adjustments.

Soon avaible at Fibre Lyte Composites..

Dusty track?? DIY differential covers

download this image, print it on glossy paper,  attach a double side tape on back and follow the shape with a good cutter......
