A dream of creating my car was finally realised in 2005 with the Vantomme M1.1
(a concept car based on the SpeedMerchant Rev4).
The first try was merely a check whether the carbon fibre supplier could do the job...
He did a superb one, so my ambition was now a truly own design...

A few corrections were made to the very first design:
1)numerous chassis cut-outs
2)extreme small lower motor plate for easy access motor
3)a sharp X shape front design
4)a very short chassis with an extra bumper to attach
5)own designing using AutoCAD program to realy fine-tune the chassisline

The 'VantommeM12' (2007/09) hit the circuit for the very first time last weekend, this during a 'MRCZ Challenge race' (qualified in 2nd, 3rd in race),
battling with CorallySP12M, Hotbodies Cyclone12, CRC T-fource and L4's. Further testing and exploration of the car its possibilities are sheduled!

anything else on this car??

"New" prototype car by vantomme : Arrow.

Sneak preview:
Arrow 02
Arrow 03

Ideas...
- starting point: no 'traditional' battery location
- create some space for electronics (pretty hard with battery placement)
- rear suspension : CRC/Speedmerchant based (springs/tubes)
- rear pod : center pivot based CRC x-pod
- rear pod : V-dezign pod

Following soon...
*More pics on vantomme-Arrow
*Update on vantomme-M12 (new chassis + Arrow rear design)
*1/10th pan car (Arrow based + 4 cell + 200mm like CRC / SpeedM / BMI )
*Carbon axle spacers
* ...

Very nice job. I always dream of doing the same. Hopefully next year after I take CAD/CAM at my school, I will be able to design and build my own 12th too.

Benedict

Thanks RCSteve.
Once you get started with CAD/CAM and master the basics,
it's really great to design... and to keep on designing...
(really need to spend more time on racing instead of
designing ...)

Benedict,
car looks great congrats.

New pics of the M12 (BL edition) & the all new Arrow chassis design:

The weight of the cars ( 2,4 mm carbon chassis) is considerably lower
than the previous versions ... (864gr)
(fully loaded, with Novak BL - as shown on pics)
M12 : 845 gr
Arrow : 834 gr

Both cars will use the V-dezign motorpod (red Arrow now shown with CRC pod), but lower motor plate has an extra hole for the left hub so that the
'old' Asso/CRC style motorpod can be used.

Front suspension is pretty standard, every Asso-inspired (Asso L4, CRC pro-strut, IRS, old skool, ...) front arm fits the chassis.

More pics of the Arrow :

Arrow (side view)
Arrow (side view2)
Arrow (front)
Arrow (silver/V-dezign)

With an extreme short chassis, well placed cut-outs and 2.4mm thick, the Arrow turns out to be a very strong and lightweight chassis; only 33 gr!! (without bumper), making it a very light 1/12th car...

More to follow

come on Benedict-

Sure the chassis looks nice ... but when it comes right down to it you are just making something that someone else has already done. Just like all those other teebar cars out there. Why not design your own rear pod with something other than a Associated front end. Now then you would have my attention. Be original!

persuading them is the hard part. my teacher is so afraid of it it's unreal.

Benedict

Yes, exactly, another 1/12th car

... you've got a good point... it is maybe time that I start off with an own designed t-bar car...

Now that's a good question with a very simple answer: money and resources! I feel already lucky I have found someone who can create customized (= original?) carbon parts for me. Would I love to create my own pod? yes sir! but you are not talking to a company like CRC, Corally,... just a hobbyist having a great time creating his own race car(chassis) if I find someone who can do it (pod), I'll keep you posted!

I believe I already have ...

That's not my greatest concern when deciding on the pod, front and rear suspension... I choose to look at (proven) functionality and simplicity (in use),
and for the carbon parts... they are original

Benedict

The Arrow with brushed ESC and motor reaches 825 gr!

After the first run with the M12, I must say it is a very fast car!
FRONT
springs : 0.022
suspension : old skool
tires : jaco 2xpink

REAR
springs : white
tube lube : CRC red
tires : jaco yellow

Center spring : gold / 30wt oil

Just not enough steering, so will go for 0.020 or 0.018 front spring
or for jaco black / gray tires.
The chassis itself provides lots of grip, for indoor carpet racing
a bit too much => too much flex (better for outdoor/asphalt?)
=> maybe look for a 3.0 mm thick chassis for carpet ?

Also thinking about moving the side links (chassis points) a bit more to the front and the inside (thanks to the wider chassis I have plenty of space to do so top view). I'm curious about
the effect (if any) on entering corners ! (see CRC - Battle Axe- - they placed there links -on chassis- more on the inside)

Benidict, Great work!

The arrow looks to be a killer car. Reminds me of my Darkside MX2 but with GREAT improvements over the Inline Battery design: Larger area for ESC, Refined Upper Battery holddown, Lower Super Structure.

You mentioned the car had a push, is that because there is little weight transfer when slowing down for corners? I remember my MX2 was a killer car for sweepers and highspeed corners just I had to really slow down for infield.

The upper battery mount looks nicer then the Darkside but I prefer the posts in front of the battery like the Darkside. A fairly hard accident is going to eject the battery right through the servo.

Overall a nice looking car though. I really like the way you did the side spring mounts.
