@Danosborne6661: That's a sweet little car you got there!:cool:

DrPaul 11-10-2013 06:12 PM

I took out the weight from my car, no brass bulkhead, no lipo weight and the car is much better i only have 20g just in front of the servo, no alloy parts. You just need to raise or lower the inner ball joints & lengthen or shorten the links to adjust grip from slippery to grippy tracks. :thumbsup:

The heavy brass weight is for the MR car, not for MM.

I added 15g to the front of mine which I removed when I bought the ally upgrades and optional brass 11g bulkhead nose weight. I run stagger ribs, but you can run cut staggers if you want more front end. The car grips like mad, but has loads of steering when you want it.

Thanks! That's what I thought of doing.

Can anyone else remember how you shimmed the gears?

skyaflake 14-10-2013 01:28 PM

I received the carbon chassis, front and rear-towers. I will take some pictures of them tonight and show them here and on Facebook (url is in my signature). Mounted and unmounted of course. The first "batch" is just to test the production process and quality.

I will test them Wednesday and possibly Saturday on a tight indoor track. As far as I can see and feel, the quality of the parts is fine.

Already I'm having another idea for a small tuning part to raise the gearbox. But this is still in the drawings. :D

skyaflake 14-10-2013 06:43 PM

Pictures are up at : http://blog.rccss.nl/2013/10/b-max2-...carbon-please/

Will make some pictures of the carbon chassis tomorrow. :thumbsup:

skyaflake 15-10-2013 05:32 PM

And pictures of the chassis: http://blog.rccss.nl/2013/10/well-be...pics-included/

Will be testing all parts tomorrow.:thumbsup:

mes 15-10-2013 06:07 PM

Sweeeet! :thumbsup: What price range do you expect for the individual items?

dikke hond 15-10-2013 06:47 PM

I will keep an eye on you tomorrow, skyaflake!! :D

Front tower will be around 10 euros. Rear tower will be a little bit more expensive. I guess to 20/25 euros range.

For the chassis I'm aiming at the same price (or cheaper) as the Alu chassis. Guess around 40 euros.

These are all estimates, but I want to have good offer for everyone for a fair price. :thumbsup: Just keep checking the blog or facebook. I, of course, will post here too.

I've received a lot of visitors, thanks everyone :wub

@dikke hond, you bet, lol. :D

Quick question does the ver 2 bmax2 come with ti turnbuckles? On yokomo website it shows a few pics with them fitted on the v2 car and other pics the steel ones?

discothesnake 15-10-2013 10:20 PM

Hi Mark, I don't think it does. The only differences seem to be chassis, idler gears and geared diff. I think.

Very nice. what's the flex like on this? what thickness carbon sheet?

skyaflake 16-10-2013 06:57 AM

2.5mm, flex is between the plastic and alu chassis, but the carbon chassis weight is less. I'm going to play around with the parts tonight at a indoor track where I drive regularly.

MHeadling 16-10-2013 08:39 AM

Cheers for the info Disco :thumbsup:

skyaflake 17-10-2013 07:54 AM

Did some testing yesterday: chassis was great. A little bit more flex than the Alu, spot on for me. My motor was a little bit too much for the track (again), will put in a 8.5 for the next time. The towers were good, no problems with them. :thumbsup:

mes 17-10-2013 11:41 AM

Did you crash enough to test them properly? :p

mekios 17-10-2013 12:07 PM

Has anyone found a good delrin replacement for the rear-rear hinge pin bushings?
The stock ones seem to be wearing out soon.

Not had a problem. What surface are you racing on? Dirt?

Yeah. I was upside down a lot when I was having way too much traction. :thumbdown:

No real crashes to be honest. But testing will continue of course :thumbsup:

As far as I know there is no replacement part. I found no real problems with the bushings. Are you racing on dirt?

mekios 17-10-2013 03:18 PM

Yes, i did in summer. Now only carpet and astro.
Well it's obviously from dirt and i had seen some Ghea delrin inserts, though they were for Associated vehicles.

Typical that I went to order the carbon battery holder today and it's now out of stock!

In stock at MB today. I picked one up this afternoon.

skyaflake 21-10-2013 06:53 AM

Team Azarashi "Erithus" has been released. Will be available soon (early mid November) at your Azarashi dealer. (In the UK that's DMS and X-Factory UK Dealers..) :thumbsup:

I'll (see sig) be taking in a couple as well. But for the UK guys out there ordering at DMS would be easier.

OneKiwi 21-10-2013 08:52 AM

Sorry but I think that body is just ugly. Im one of the few people that are for the cab foward designs.

skyaflake 21-10-2013 10:07 AM

I kinda like it. I miss non cab-forward bodies, even though I like cab-forward as well.

mes 21-10-2013 04:05 PM

Most bodies can look great with a decent paint job; sometimes you just need to get used to it. When the Bulldogs were released, I thought what a f*ugly shell, but now I like them and hope there'll be one for the MR in the not too distant future.
For now, I am without a buggy and will 17.5 turn race short course with the other guys in my club - unfortunately, there are hardly any buggy drivers left. My son, however, found the MR much to his liking, and is getting better and better, at the age of ten possibly already better than me. He will need a mid-motor shell to match my one-race-old RM Finnisher. Well, I've always liked Azarashi, and my son has got no choice! :p

For dirty low traction tracks, which is better (rear motor)?

Standard size lipos and esc on top

http://gigantesrc.com/116-168-thickb...-10-tt-2wd.jpg

Shorty size lipos and esc behind the lipo

I feel a lighter car is more nimble and faster to change direction. A heavy car is slow and sluggish, but safe(r).

I've not run the bmax 2 as a rear motor, but on dirt/clay I much prefer my b4.1 with a shorty and esc mounted in the space behind, than with a full length stick pack. I'd go shorty myself.

skyaflake 24-10-2013 07:29 AM

Did play around last night on my local indoor track. We were allowed to use traction additives. I just put on some old (pretty) worn out Nanobytes, car was great, despite the lack of on-power steering.

I just need to setup the car for a little bit more on-power steering, probably I just need to loosen my slipper a bit. The car goes a little bit (too) wide. Off-power steering is great.

Carbon parts held up great. Release is scheduled for begin November - as it looks now, I'm going to be busy with the B-Max4 release as well :yawn:.

I actually preferred the shorty battery with the esc on the side or top. Depending on your track, you might want to run the shorty in the rearmost position.

skyaflake 28-10-2013 10:32 AM

Carbon parts (chassis and towers) are going to be produced asap (I've sent out the order).

Prices will be announced as soon as possible. They should be competing with other carbon parts making brands :thumbsup:

I purchased a Hyperion saddle lipo yesterday only to find it does not fit my BMAX2. I cant close the battery holder after i put the lipo in... Is there any way i can make it fit?the dimension is 69mm x 46mm x 31mm

That lipo is oversized, not a fault with the car. 31mm height is too big, normally lipos are ~25mm high. Send it back and use regular sized packs.

Limit front droop. Mine extended part of the shock shaft is about 17mm while standard is 20.

Thanks, will try that :thumbsup:

Hi there

Someone try to make a bulldog fit to the bmax2mr?
I tried the jconcepts for the rm bmax2. It looks horroble.

Mike

skyaflake 03-11-2013 03:36 PM

Prices of the B-Max2 Carbon parts are here:

http://blog.rccss.nl/2013/11/busy-wr...re-the-prices/

€40.- for the chassis
€10.- for the front tower
€25.- for the rear

Guess that's pretty reasonable.

skyaflake 05-11-2013 05:57 PM

And now in stock. First batch is limited, so don't sleep :thumbsup:

any idea if the front brace for the alloy chassis is available by itself?
and what the part number is?

skyaflake 05-11-2013 07:21 PM

it isn't as far as i know :thumbdown:

Brett.w 11-11-2013 05:43 AM

Hi Guys

I have a BMax-2 MR running in mid motor (8.5t) configuration and stock set up apart from adding 3000wt oil to the rear diff.

The issue I have is that it is impossible to put the power down with out it the car veering to the left or the right, coming out of a slow corner and accelerating is very difficult. One of the marshals said that it was because one of the rear tyres is ballooning before the other?

I have tried the rear motor configuration and it still does the same thing.

The track we run on is low traction, loamy dirt.

Any suggestions would be great thanks.

Cheers

Brett
