Final 2


http://yokomo.blog.free.fr/index.php?

Got car today the build is on cheers Gary at Morley models and Michel at mb model's! But which car will be. Built first? Come on Ross get your finger out!

Anyone got any thoughts on which is best battery placement, I have shorty and saddle pack. So have three choices saddle or shorty straddled across, or shorty up the middle. What are the advantages and disadvantages, I will be running mainly outdoors on astroturf, so a bit slippy at the moment.

Thanks.

saddles i would think

bmax2mr spare are on website what i have left
there is 1 spare kit from what came today
see what comes in a friday

haha i just need to build shocks and fit speedo

I read about gear diff on carpet.
Is associated the only brand which has has no issues with ball diffs on carpet? I seems to me associated b4 series has the best ball diffs, because i dont see people prefering a gear diff on carpet on their b4's

I'm not sure any brands have issues with ball diffs, it's more of a personal preference thing (and current trend!) if you ask me. They are just different!

From the advice I've been given gear diffs should work better on consistent, smooth and high grip tracks (indoor/carpet for example) whereas a ball diff should to be better for varying/low grip/rough tracks.

I'm told gear diffs generate more drive when the grip is good, but a ball would feel more balanced when grip is less good.

And don't be fooled into thinking a gear diff is less maintenance either, from what I've been told gear diffs need attention too as they tend to loose oil, some slower than others, but oil checks are needed. Not sure what is worse either, a worn ball diff or empty gear diff?

Treat them as tuning options, not all round solutions!

AE are just slow to react, they do have a gear diff from the SC & RTR that some people are fitting I think, but you need the right car/gearbox/bearing combination for it to fit!

Thank you.

Manual online.

I quite fancy trying the geared diff but only on carpet.

I remember at the oOple race 2 years ago Team Durango factory drivers were running a dry geared diff in the 210. I may be wrong tho.....

Here is mine all complete. Brand new Speedpassion Reventon R speedo. Great value.
Just waiting in shell.

i have 1 gear diff left

Looks lovely, Your have to let us know how it goes! :wub

invoice sent gear diff sold to dave

no gear diff in stock now should be back n stock middle of next week

Will do! Will be trying it on Sunday :thumbsup:

No worries Craig, will sort it this evening.

Dave

I notice that Hayato is running in the Reedy Race this weekend. Will be interesting to see how he goes. Didn't see Naoto on the list tho.

Barry Baker is also running Yokomo in open class.

Neo is covering the race.

Any tips on building the car?

I found the layshaft had quite a bit of side play on my build, so I added a 0.2mm shim on either side:thumbsup:

Shock oils and pistons, I'm still pondering at the moment, as I plan to run mainly outside.

Yeah I noticed the play on the lay shaft. Ill need to get some shims.

Front end is very soft. I'd use piston no.1 in front and if your running on high grip then a stiffer spring will be needed. Either that or use Naoto's set up and go for 60cwt shock oil!!!

Building shocks tonight....not sure what to do with pistons...always ran associated 2 in front and 1 in rear on my Vega on astro So was thinking the same for Bmax to start but all the setups online seem to be 2 in front and 3 in rear??

Pistons
 

Yes 2 in front and 3 in rear...

What is the order of the pistons?

I take it 1 is the smallest hole to 3 which is biggest?

other way round from what i could see

heres mine.... need to shorten the motor wires a little but otherwise ok.

No they are the opposite way, which makes it a bit confusing as I would normally run a smaller hole piston up front on 2wd.

On measuring:
No.1 = 4 x 1.4mm
No.2 = 4 x 1.3mm
No.3 = 4 x 1.2mm

I know Sylvain, Naoto and the rest of the Yokomo team have found the ideal setting for racing indoors, as has been proved. But would this be ideal for outdoors on more bumpy tracks? I only ask as I'm unsure what route to go.

Yes this is why i am confused because I am the same...have always run smaller holes on the front.

Don't those indoor setups use 60wt oil in the front? sounds like it setup for less pack due to bigger holes but slowed damping movement due to the oil vicosity. Suspect it setup that way to slow the car movement down in yaw and braking on indoor tracks. or the blue springs match the damping for that setup.

There are some set-up sheets on PetitRc for the old rear motor car on outdoor astro tracks that I am going to use as a base. Red springs on front and blue on back with 30/35wt oil seems a reasonable place to start

Also that setup was used at the EOS were they were running D-boot tires. D-boot tyres make allmost all cars traction roll, at least my X6 doesnt like D-boots. Thats why the yokomo guys used that pistion shockoil combination i think.

Build
 

Finished my B-Max 2MR build yesterday, got to say it was a pleasure to build and went together very easily. Can't wait to race it next Sunday.

thats gd to hear

Mine all finished. Quick rattler shell while I wait on pro painted one.

Hope it goes as well as it went together.

gave car it first run today.
Very nice indeed.

Just need to get hold of one of the narrow bulkhead arm braces. Don't get why its not included in the kit when you get both bulkheads. Not in stock anywhere either which is slightly annoying.

Found I had a little understeer so moved the steering knuckle spacer to above so it dropped the axel 1mm which made a big improvement.
Think ill remove one spacer from front shocks too.

Does anyone know what weights the team drivers and using in the bulhead?

Looks great.....just finished mine and looking forward to trying it out tomorrow :thumbsup:
