I fear these will be too dangerous. I dont want to be a kill joy, I love models. Without suspension, it wont take much to lift the nose and if you know what happens to a 1/8th when the nose lifts, there is no way I would marshal it, specially with EP drive. Car park racers need only hit a stone and the car will become a plane...

One of my club members adapted a 1/8th IC car to EP, it was insanely fast and heavy. I was sitting marshalling on the twisty section I could not hear it approaching. A 2S version would be advisable to keep it light if you want to attract newcomers or beginners.

Just out of curiosity, why 4wd? It would seem that if your ultimate goals were simplicity and low cost (to get the most people involved) you would do a 2wd version with the same basic principals.

His intent was an entry into 4wd, with no suspension, the car initially shown was a 4wd IC car. TOM is trying to get people into the hobby by simplifying it. It is simpler - no suspension, single belt drive vs three etc. In being 4wd it is also more newcomer friendly, i.e. it is much more easy and forgiving to drive.

What are you going to use to secure the steering blocks to the front arms? I like the electric setup, looks simple and easy to maintain. Have you thought about making conversion kits where you can just unbolt the front/rear ends of some of the current 8th scale nitro cars and just bolt them onto your chassis?

I like this project very much! I'm looking forward seeing pictures of the nitro version.

@TomAt
Are you going to sell these cars?

Rollout of pre seria models on April 25th
 

Rollout of our pre series electric models: absolutely fantastic!!! :):):)

We finished 6 cars (a lot of work and rework for the first ones ;) went to the track and did run without any setup modifications - as there would not be many.
total weight with body: 2250g with 4s LiPo and 2300KV motor and 120A esc

Even other nitro drivers tried and all were deeply impressed!

The next day there was a race at the Stoehr-Ring: 2 Serpent 977e and 7 BURI-Racers (+the prototype car)!
in the finals the top laptimes were: Serpent 977e: 18.000 BURI-Racer: 18.423
Thats half a second for an unsuspensioned car! Absolutely great!
Have a look at the race results at:
http://www.morac-graz.at/rennen/2015...1-8/index.html

And have a look at the reactions on fb.com/BURIracer

@ blis: The danger depends on the attention of the driver. My expirience is, there is no differece between suspensioned and the new unsuspensioned cars. My cars pass curbs nearly the same style the suspensioned do.

@ s1a1om: Thats what I would have answered: 1/8 IC Fan is absolutely right

@ JLock: This first version comes with fixed steering blocks, I am already testing front steering blocks with pivot balls. So probably I will change the next seria to this style.

@ Johnson40: Bad news for nitro: in this moment all energy is on electric version, because of more interest.
Yes we are preparing a real commercial seria with professional partners first the electric one - but my heart still is for nitro.

I will keep you updated.
best regards, Thomas

Wow!
Thanks for keeping us updated (^_^)

BURI Racer E1
 

BURI Racer E1: absolutely simple - minimized construction, maintenance, setup and easy to drive! Time for a lot of fun!

Looks really, really, good. How much for the kit and where could one buy/order one??

@ JLock: Sorry, but it needs some more time.

We just finished a pre seria of 15 cars, test them the next three weeks to find weak points and then we start production of 50 / 100 or 200 cars. In this case we will give every purchase and sales in professional hands to get serious products.
It will last until summer to be able to offer and ship the kits.

In case of interest please send me a pm so I can inform you directly.

regards, Thomas

My next car is ready for rollout: I call it BURI-Racer E2 because of 2x 2sLiPo
In the front Pivot balls and many standard parts, the belt in the middle.

But there are some pros an cons compared with my E1.

some short videos you can find in Youtube: search for BURI-Racer

Wow this bad boy is already starting to evolve!!! Looks good!!!

Here a video of the first laps with the BURI-Racer E2:

The next cars are finished: BURI-Racer E1

And one picture of all the parts (exploded view) - not many?! ;)

Nejc Mihelič with the Buri Racer E1 - just a few easy laps at the end of the race in Tolmin. :) :)

The asphalt is rather new, so the best condition for the unsuspensioned car.

International Race of MORAC-Graz
 

Last weekend there was really a great race at the track of MORAC-Graz! More than 60 competitors did fight in 6 classes (1/5 gas, 1/8, 1/10-200 and 1/10-235 nitro, 1/8 and 1/10electric).

In 1/8th electric there were 11 drivers with 10 BURI-Racers and 1 Serpent 977e.
The winner: Martin Burger-Ringer 2nd: Nejc Mihelič 3rd: Pascal Knoeller , all with BURI-Racer E1
The best laptime of Nejc with his unsuspensioned BURI-Racer E1 was only 0.7 seconds slower than the best lap of the day with his Motonica / Picco (16.80)! Thats great!

Evaluation model for the seria
 

Hi,
here some new pics of the evaluation model for the serial production:
some additional features and again a bit more simple!

I hope the next pictures come to show the ready sets for delivery ;) I hope until the end of August ;)

And the first laps with this car: Mounted - switched on - driven - setup? no need! - just have time for fun! :):)

BURI-Racer E1 serial production
 

Coming soon: production in progress... BURI-Racer E1 the pure 1/8th electric racing car! Have time for fun! The availability will be at the end of August.

Die Produktion läuft: der BURI-Racer E1 ist einfach - mehr Zeit für Spaß!
Ende August ist es so weit!

Looking Good!!:)

These cars look pretty awesome, please keep us posted when available in the States!!!

fantastic. looking forward to usa availability

Last weekend at the 2nd international clubrace of MORAC-Graz there did start 9 BURI-Racers and 1 Serpent 977e in E8. The winner was Martin Burger-Ringer who was best in all 3 final heats. The best laptime of the day by Marcel Knoeller was only 0.4 sec slower than with his Shepherd/Woldt Performance nitro car!
Look at the video, Marcel is pretty fast in the green car...

Thomas,

I'm back in the U.S. let us know how the cars doing during the ENS this weekend. I see no mention in Redrc as of yet. Super excited to put a chassis together.

More to follow...

BURI-Racers Presentation at ENS in Ettlingen
 

Hi,
my friend Tommy did a fine work in Ettlingen, sadly RedRC doesnt look at non sponsoring items.
But after the race days some of the very top drivers did try the BURI-Racers and they were surpriced of the performance and really had a lot of fun!

Many people did agree that this type of car will have a real chance to be established as some kind of stock class for 1/8th electric! Low costs and minimum maintenance are important arguments!

I did make some short videos...

+ YouTube Video

+ YouTube Video

Fantastic!

Which is strange, because many times when there was a demo class at other events i.e. F1 they had some mention.

Either way, this will be a great class if the TTB motors stay out, maybe Ernie P. at Trinity could offer some spec 1/8 2100Kv motors that would go we'll with the class given he is all for spec racing, and keeping cost down. The 480+$ TTB motors may be the cream of the crop for 1/8 on road, but you still need the ESC, and not everyone can afford that setup.

On the otherhand, Thomas what motors and esc's did you guys run, 2000 or 2100's.

Hi,
the 120A escs of Hobbywing are really good working ones (SCT-Pro or WP-SC).

The motors we tried, but i am not fixed yet:
- Turnigy 2100 and 2300kV are the cheap ones but ok and well working
- SkyRC Toro X8 2250kV very powerful
- Hacker 2100kV very powerful but expansive

2300kV is really the maximum, the cars are very fast, I think 2100kV might be the the right choice to drive fast and have fun

Motor and ESC have arrived, awaiting Servo and Battery. Will post built pics.

Here is the progress sofar. Hardware swapped for stainless and ti. The new X-tyres will be replaced by some trued matrix tires.

More Pics, OCD set in. Replaced the turnbuckles with Titanium ones, made a receiver box (courtesy of an MP9) and mounts for it. Soldered up the ESC. Mounted trued (Squared) Matrix tires, made a new tensioner for the front to relieve some of the tension on the drive belt (was causing tweak - left side was -3mm vs. the right). Body has come in - just waiting on the Batteries, then finish soldering the ESC install correct length antenna tube, and get some asphalt under it.

So we put a few laps in, and have to say it drives very well. Son is still getting used to the power delivery - I will change the profile in the ESC, more on that later.

Put about a solid 15 minutes of running in - parking lot until body is finished then we will hit the track.

Motor never got above 125, and ESC stayed around ~98-101. Mind you these are all temps without the body on, and its 85 out with 61% humidity here.

The drive off the line is immediate and very direct although I noticed you have to watch the front to rear Diameter Bias on the tires. you can easily break the front loose once you get into the higher RPM's - I will play with the bias here in a bit.

It drives very well, reminds me of my Pro10 days, and the rear is similar to the chassis that had wide pods (Delta Villian, RC10L & maybe the TRC Pro 10).

The front end also reminds of kinda of the 200mm 4wd cars, having a one way setup, but the fronts reaction is different that 1/8 IC cars which I believe may be because of the lighter weight carried on that axle.

You get a bit of torque twist once you get the Motor to deliver its full potential too abruptly. If you use a smooth throttle delivery the torque does not over-ride the belt and cause the tweak front to rear. - I will see if the new throttle profile will help with that as well.

Sofar we can't wait to put some Foam down onto the track soon.

-only other updates since the last pics are the addition of the chassis protector tape, and the application of silicon spray to the belt to minimize dirt and debris.

Videos look great and cars very fast!
Can you buy this in europe somewhere?

Yes at the time it's only available in europe. I think Thomas may have finished the production cars. If you PM here or go to Buri Racer .com site you may get ahold of him that way too.

I know they just finished running in Italy at Mantua days.

Yeah saw that.

Thanks a lot! Looking cool indeed! Love the simplicity.

Awesome!!

@1/8 IC Fan
Really like your updates (^_^)
I just can't wait for the Buri Racers to arrive....
Meanwhile, I showed the Buri Racer website, pictures and videos at my track yesterday. Got a lot of enthusiastic reactions!

Can't wait to get mine... :sneaky:

That's pretty cool. Did you do any tailoring of the plies in the composite chassis and arms to change the spring rate or damping characteristics of the car?

Hi,
one main benefit is regarding the setup: Really, no changes needed !!!
Besides:
- you can adjust a little bit the flex between the chassis and the accu-plate and also the tweak of the frontend.
- you can move the upper arm plate a bit forward and backwards.
- there are different upper arm plates available to change the front camber between 0 and 3°
thats all you can change, you will not change everything: just drive and have fun!

Thanks, I hope it will help some. Plus everyone loves pictures.

I think that with a lower downforce body (given the cars lower weight) it will be a blast on the track. I can already see that it will curb the common detractor of regular 1:8 IC cars (tuning and cleaning). You can focus on driving and the adjustments are minimal (Toe, Caster and front end flex). Its nice to have a car on the pit table and not need a bunch of cleaning and adjusting.

I will concede that I went overboard on the Electrics and Batteries, yet have a simple 2100 KV trackstar system w/ 120A ESC is on the way. So as of now, I am playing with the ESC profiles, and have set the BEC down to 6V vs. 7V. Also to note I am running old 1/8 foams from my other cars - the Matrix wheels being a tight fit to get the QD to close, I will try some Hot-Race and Enettis's soon.

We will take it and the P8F to the track to run some numbers and see a direct comparison.
