I have some questions about the electronics...

How much weight the car without electronics (but with tyres)...¨

I can see thta most of the people are running 4s with 1/8 electronics. I was thinking about using the car as light as possible... Is it possible to mount a 540 motor on the E1?

My objective would be to run the car with 2s or 3s with a TS160 and 540 motor (2 poles or 4 poles)

Do you think it would be possible?

Hi, I published in my facebook page fb.com/BURIracerE1 an album with the weigths during the finishing steps.
I have to add a picture of the rollers weight with tires but without electronics

But you can re-calculate:
1830g (roller+motor+esc+battery) - 850g (roller only) = 980g for electronics
2250g (ready to run) - 980g (electronics) = 1270g

To use 3s might be a good idea, i completed some of the pre serial cars with simple Turnigy and Trackstar components as a 'junior cup' edition for our youngsters. A bit slower but still fast enough and a lot of fun for beginners
And some days ago I ordered a Tenshock SC-401 V2/5Y - 3400 RPM/V to test with a 120A SkyRc Toro SC120 esc and 3s battery. Because of the price this would be a very interesting combination. So the TS160 will be more powerful, but i dont have any experience with this esc.

Besides i just finished an extreme lightweight custom made BURI-Racer E1, the rollers weight is less than 750g!

Best regards, Tom

Thank you for the information.

The TS160 is a pure 1:10 speed control, I'm not even sure it will accept 4-poles motors.
My goal was to use touring car configuration on this car, as it is very lightweight, but it seems a little bit too heavy for that... (the heaviest car I run with this kind of electronics is a 4x4 Durango which is 1850 grams RTR)

I can see on the last picture that you are running without additive, we are trying to promote the same thing here for all categories, have you a video of how the car is behaving without additive?

Hi, I think its realistic to reach 1850 grams RTR with the BURI-Racer when you use 3s components, leightweigth body, rims and maybe some lightening additions on the roller chassis. I will let you know with my own tests.

I never used tire additives - i am strictly against this. In all my videos on my YouTube channel BURI-Racer I honestly can say no driver ever used tire additives! Its just fun and even on a dusty track it makes fun to drive the BURI-Racer!
The sticker is from a swiss guy at the time the additives came to 1/8th nitros... I like it, because i want to stay the hobby easy - at all!

One of coolest threads I have ever read. I really like the design of the E1. I'm curious though why Fibre Glass/G10 wasn't used instead of Garbon Fibre to further decrease cost?

Hi DavidNERODease,

i already built some cars of the pre seria with glass fibre chassis, they were absolutely ok. But talking with RC-fans there are not many that would accept a lower priced car if they have the chance to get a carbon one for a bit more.... In Italy some companies offer a kind of silver looking glass fibre chassis, but due to the loss of price difference it doesnt really make sense.

Best regards

Hi TomAT.. I send you a PM.

Parcel is travelling, I'm so impatient... :-)

EDIT: My parcel is here! It seems very very very robust (by the way I'm used to 1/10 cars...

Has somebody already try to run this car with a 540 motor? In 2s or 3s...

Hello Airwave, I did my trial run on a damp track with a 2200KV motor and 4S. This set-up really makes the car fly! The moment the weather allows I'll try again and will also try a 1900KV motor.

1:8 systems are very affordable:

If the only thing that you want is to make some laps, or run the car on the street, of course you can.. But it is not going to be fast if you use the right gear to keep the motor in safe running conditions. (Not only the overol weight is important) the movements parts are heavier than any 1/10 scale especially the tires and the axles.
If you manage to adapt the 540 motor can to 1/8 scale motor mount, (I don't think that they share the same bolt patern) You are also gonna have to use an adaptador for the motor shaft. (the 540 is some like 3 mm and the pinion for 1/8 are 5 mm). OFNA use to have that adaptor in the old garmin SCT that maybe you can use.

good look with you modification...

Attention please ! ! !
I did try the hobbykings turnigy waterproof combo you mentioned above. I ordered at all 14 sets with 1900kv up to 2300kv because its really cheap! But 8 of them burned within the first 3 battery runs! The esc can be really dangerous! Please take care!

My recommendation is to use a 120A 4s esc like Hobbywing WP-SC8 or SCT-Pro or SkyRc Toro SC120 and a motor like SkyRc ToroX8 1900kv. Its not that expansive and many of our drivers run this without any problems and they are still fast!

The holes distance is the same, so 540 motors will fit. I will try a Tenshock SC-401 V2 3400kv motor the next weeks, it has a 5mm shaft. I want to run it with 3s LiPo. Maybe a good combination, lets see.

After going back a few pages (reading and looking at pics), make me want to get one now!! The car looks great (machined neatly, fit and finish looks marvelous). Will have to move some older r/c stuff so that I can try to add one to my collection (and maybe start a class of them in my state's series race).

For those looking to save weight, I switched to a SC based 550 motor (LRP 10L) and am running a 3S LiPo with no issue. I have modified the chassis a bit to lower the weight further. Yet as Tom has already stated the car with a 550 1/8 motor and 4S far from needs tire additives / traction compound, if anything I feel the car when running my worn 1/8 tires from my 4wd IC chassis, does not let the chassis work as well. The chassis feels like it's in a bind and reacts similarly as a 4wd IC car when it's tweaked or you stripped a shock rod end out of its threads. Just my 10 cents.

Hello,

With the beginning of February i announce some news: i, Thomas Burger-Ringer, distribute now alone by myself. I sold out my partner that was reponsible for sales and b2b business.
The BURI-Racer E1 shaill be offered by a dealership network - dealer inquiries are welcome, please send an email to: [email protected]
