[MHeadling]

Hi Chaps, you may have seen our car in the Petit Rc report, I thought id post up some pics of it in detail if your interested?

As you can see in the shot the chassis has been milled out so the servo wire runs under the cells:

[GRIFF55]

looks good!

[MHeadling]

So here is the latest pic, Scott (Rebel RC) has got a anodizing machine and its gone orange! I will get this together shortly and give it another run, so far it goes pretty well on the high grip, just need to get some better set ups/weight distribution on the car! We have had some interest from the US about the car but have not drawn it in CAD yet, who knows if it will be released as a kit? It will prob be too expensive but we shall see.....

Looks pretty cool. I love the orange anodizing.

[coolcars782]

Wow that looks really good Mark. Is this going to be put into production ?

Carl

[Aran]

hi mark,

nice looking logo you have there :thumbsup:

just wondering if the chassis is the same length as the standard b4 chassis?

if not how much longer is it?

thanks

[tymill]

I'm liking the anodised chassis.... how about going Gold as an homage to the car's '84 roots?

Cheers,
Ty

[MHeadling]

Thanks for all the interest in the car guys!

Just to answer a few of your questions:

It's exactly the same wheel base as a STD B4

Yes Tymill gold would be cool! We can anodise it any color you want!! Or maybe supply it clean ali and you get it done perhaps? Who knows it's early days!

Its hand machines at the moment and we are not sure to put it into production? If any of you know how much something like this costs to CAD and CNC machine then please let me know.

Big thanks to Aran for the design work on the SMR decals you can see on the car and Dave at A Signs for the decals and T-shirts!

Basically you just bolt your B4 front and rear ends on the chassis, fit a low profile servo and saddle packs and your good to go!

The shell you can see Scott (Rebel Rc) made from a pop bottle.

I'll let you know some news if we can work out production costs etc!

Car looks awesome, but I don't think DMR Bikes would be too happy

[Jamie.T]

P.M sent, im very interested in possibly buying one of these. All depends on price of course.

Jamie........

[MHeadling]

Well spotted on the graphics front!! We may have to design a new logo!!

When I can find out cost etc I'll let everyone know!

[Aran]

Car looks awesome, but I don't think DMR Bikes would be too happy

http://www.mtbracephotos.co.uk/mtb/images/logo_dmr.gif

yeah if you started to sell them dmr might get little upset, might be able to do something about that

[MHeadling]

Cheers Aran, I'll be in touch about a new logo, I dont want to upset DMR!!

I just saw the logo on my bike and thought that will do for the petit as we were pushed for time, something a bit flashier will be on the horizon!!

I think I need to get some cars made first before I worry about stickers! :D

[MHeadling]

Some more pics I have found of the build:

[Thomas P]

Looking ACE Mark....Just hitting F5 all the time now :D

[BloodClod]

Very sweet car!

How does it run compared to a standard B4?

Can't believe that was machined by hand - simply amazing! How long does the machining take per chassis?

[B&H Racing]

Your car does look good Scott/Mark :D

And up against it, don`t it look like the X6 ate all the pies !!! :woot:

[MHeadling]

A couple of pics of Scotts car, its been tango'd!! :thumbsup:

[j.m.]

How does this chassis change the performance of the car?

Jon

[MHeadling]

To be honest I found the car great on high traction surfaces, it jumps well and I found it nice and easy to drive, we havent done alot of testing with the car so have just been using B4 set ups on it so far.

We have only ran the car the the Petit RC (carpet), Eden Park (Astro), Will Johnson ran it at Worksop and Spud 31 ran it at Stofold so its early days!

When I get some chassis made up it would be good to get some set up work done on different surfaces etc.

[Aran]

does the chassis just fit saddles? or can it be adapted for sticks? :P

[MHeadling]

Hey Aran, You would be hard pushed to fit a stick pack in it!

It was designed around saddle packs. There is just enough room for the electrics let alone a stick pack battery!

[Aran]

yeah i thought that, what might be an idea then is to have a low profile servo but mount it up right, there might be a shell issue but there could a more forward cab shell.

im planning on trying to get all the weight in the centre on my standard b4 chassis, just waiting to get a low profile servo. saw a guy do it to a ansmann mad rat. see how it goes :thumbsup:

thanks

[Thomas P]

Wow, Scotts car looks real good!! cant wait to get one of thoose :)

[Sk8er_alex]

Very unique car looks strong have you got the final shell design yet

[Thomas P]

Any updates Mark? :)

[MHeadling]

My proto chassis is being drawn in CAD at the moment, this should be done next week and then I can e-mail this drawing out to get some prices for machining some chassis.

As for the shell it will be the same as what's in the pictures!

I'll PM all the interested people once I have a price worked out, it will be a limited run if cars, 10-15 max. It's going to be an exlusive club owning one!!!

[Thomas P]

Sweden calling Mark, any updates on the SMR4 ?

[MHeadling]

Hi Guys, sorry I have not updated this post in a while, been busy with other things!

No news on the car really, my Cad guy is taking ages and the kick up on the chassis will cost alot to machine etc so it seems like this project will be shelved I'm afraid!

Thanks for all the interest in the car!

[Thomas P]

Mark i have a few Qs about this Project.

[Rebelrc]

Thomas PM me ...cheers

[MHeadling]

Hi Guys, Sorry for the lack of updates on this for a while, I have spoken to the CAD man and he has it all measured now and should e-mail me over the drawings next week.

I will then send these CAD drawings out to some local engineering firms and see what its going to cost to do!

Speaking to Trish a while ago it seems the kick up on the front of the chassis will be a bit expensive to do as the machine needs to be re-set to do this angle.

I will see if I can post up the drawing once I have it.

[Thomas P]

Me Like :)

[TryHard]

Mark,

On the kick-up front, could you not adapt the design to take an X-6 front plate? So removing the alloy kick-up? Would work with the rest of the B4 front end.... ;)

Looks good though :)
Ed

[Thomas P]

GT2 ?

[Rebelrc]

Mark, How fast does she go mister....Lol:woot:
Thats my car.....LUSH!;)

[metalmickey0]

I have one question. Why? , whats wrong with the original? as i now just got a B4. Well thats two questions really:blush: As all the cells and electrics are in the same place

[Tom3012]

From my point of view, when i do conversions its for fun, its also nice to be different and brilliant when your creation goes as well as the original if not better... :thumbsup:

[MHeadling]

Well said Tom!! The main reason was to try it out and be different!

Scott (Rebel Rc) wanted to get the C of G as low as possible and with the chassis milled from Ali you can't get that much lower!

The car goes very well so far! We are not amazing drivers but it's quite different to drive compared to a normal B4 and on high grip is nice and safe to drive. It does need some set up work on low grip as Spud used it at a wet Stotfold and with it being so narrow it didn't roll alot and didn't create grip like the X6 and B4 were. He made some changes to the car and lengthened the links which helped but it's early days!!

One nice thing is it's at the Brca weight limit as STD, no adding lead or brass anywhere!

But like I said it's just to be different!!

[till]

and what is the brca weight for the STD class ??

[B4 Racer]

I would like to buy one of the "SMR B4 Chassis Conversions" and boddy. Please email me at [email protected] with the price and the time the chassis would be ready. Thanks a million for your time.

[Rebelrc]

Sorry B4 racer
we never continued to develop it into production so none to sell
many thanks for your interest though:)
sorry we cannot help:cry:

[cooper_xl]

Very nice..congrats

[Busadaddy]

I wanty lol

[rcjunky]

How are the batteries held in place? it looks like they cold slide around forward/backward. I'm planning on doing something similar on my losi, aluminum chassis, mid motored, saddle packs in the same layout but I'll be using the stock front end so I won't need to mess with the kick up, and making it have the wheelbase of the 22, so it will be sorta like the 22 MM layout but my biggest concern is battery placement, the last thing I want is the battery too far forward/backwards and need to re do it all as it will all be done manually at school.

[Rebelrc]

Many thanks Will Johnson (Rc-penguin) for running this car at maritime
It looked awesome all day (wish it went that well when I drive it) and got lots of attension and comentslike what is that lol(very orange)
Cheers for the great drive will
See you tonight for some model car sliding and wheelspin!
Love it:thumbsup:

[MHeadling]

Building up my SMR B4 (chassis has been gathering dust in my workshop), been through my parts box and getting it going again for a bit of fun/nostalgia.

Thanks to Spud and Griff for the bits for the build, going to try and make a coke bottle cab forward shell for it.

Thanks for all the interest in the car!

Im a cnc machinist (lathes) but also have milling knowlege too And the kick up is no more expensive to machine than anything else If Its done on a decent machine

[MHeadling]

Some more pics now it's finished, big thanks once again to Griff for his help on some of the spares I was missing during the rebuild and to Rebel RC for making it in the first place :thumbsup:

Ok fair enough Gixxer but its all about the mid motor now so just a bit of a fun getting the SMR car built again, I'll leave the mid motor conversions to Vega :)

[Rebelrc]

Looks great Mark
It looks just like mine lol
Except mine has proper wheels on it :thumbsup:
Cheers for the cheers

[GRIFF55]

Need tyres!
No worries bro:thumbsup:

[MHeadling]

Well the last SMR B4 was stripped down and sold and the lovely orange chassis was screwed to the wall in my workshop, a few years passed and I fancied getting it built back up, a £35 B4 and we are underway! (Bling will be added!)

[alex97]

Looks good. Off topic but how do you find the 2x20 tires on astro?

[MHeadling]

Thanks Alex, I've not ran the front tyres on astro as of yet but will give them a go, I had them in my tyre box from racing on grass back in the day and they were really good
