Been racing the Buri now with more racers at our track in Apeldoorn the Netherlands. All racers who try this class are all enthusiastic. We all discusse the various things we try to get faster and `since I don`t read much about the technical side on this very nice class here are our testing conclusions.

Its track and grip related off course.

Driving style;
The former nitro 8scale racers were getting faster laptimes in regard to our former 10scale electric racers because of the difference in driving style.
So I coached one driver on the stand when to apply throttle and when not.
This racer became much faster in a short while and more important. had lots of fun. So this is important, Nitro 8 scale driving style makes quicker lap times. (brake before the turn and throttle on beginning the turn all the way out)

Weight distribution on the Buri car,
Its seems that this is not that important on this chassis in regards of lap times. I tend to always want even weight distribution so to get straight acceleration when starting from a standstill. So the best, in my opinion, is the 2x2S lipo radio plate with the esc on the side.

Batts.
When using the same kV motor the 2x2S lipo option is approx. 0,5S faster a lap on our Track. In comparison with the 4S lipo block/brick.

Body,
Used , PF 909,R15B,R18,R19 Blitz 040,035,
The R18 is very good with much steering so is the Blitz 040. The 909 is very liked because this body is very calm and fast to drive. I like the 040 very much because it gets the fastest lap times for me. Body placement is very important and moving it forward or back is needed and has big changes. More than on my nitrocar.
For bumps we use more forward rake, this is more angle although the back can not be higher/exceed the rule limit we use from the nitroclass.

Motor,
Tried motors sensored en unsensored from 1750 to 3200kV. I like the high speeds with the higher kV motors but its difficult to have lower temps on the electronics so beware. Had my lipo cuttoff higher adjusted which killed my total driving time. So in general; 1900kV will give lower temps and more drive time. Heats of 6min are good. Sensored makes a difference with starting a heat.

Timing,
Higher temps comes with rollout and timing, so beware and temp your esc and motor. Also temp your batts.
Some have destroyed their batts because of this. Lower kV and longer heats will dimish the timing and rollout and this is good because it will safe your electronics is the general consensus.

Rules,
We have adopted the general rules from this class with the 1950kV motor limit(corrally motor).

Chassis,
We have Corrally also driving on our track and we will see the Easy 8 soon from Shepherd.
We welcome these chassis because this is good for the class. The Corrally seem to do well also.

ESC,
The Toro 150A combo seems to be very fast. The HW combo is very driveable and both are fast.
I like the temps log the HW provide with the Wi-Fi module , Toro has similar I'm told with their laptop program.
Some more esc have been tried and all seem to be good.

Tires, rule 35/32 shore like the nitro`s
Matrix is very liked by the majority although I race Ennetti and like them very much. Laptimes are the same.
Other brands are also used and good. We tend to want to use one brand in the rules for our track to have uniformity and we'll discusse this for next year. Important to have pinions ready to adjust when the tires get smaller. This to keep temps in control. The car seems to like smaller tires though.

Hope this information is helpful and have fun racing this remarkable class.

great info, thanks for sharing

Hi to all BURI-Racer fans!

I want to tell you some news about my project BURI-Racer - the simple electric 1/8th 4wd pan cars:
with October 1st, 2017
- I will support dealers worldwide directly
- I deliver the BURI-Racer E1.2 kits with additional parts: the aluminum motor plate, the carrying handle bar and the motor fan mount.

The dealers list in my website BURI Racer will be updated continually.
So I am glad to name and welcome some new dealers:
- Italy: www.albertmodel.com and Hobbypoint
- Luxembourg: www.t2-esch.lu
- The Netherlands: RC-SPECIALIST
- USA: www.facebook.com/norcalpancar

Fantastic!

Kits and spares on their way to California!!

Noticed the rules for the Pancar Electric 8th class on the AGM and would like to comment for all to also comment:

STOCK CLASS (4wd Without Suspension)
11.8 Fixed chassis cars without any moving suspension components . 11.9 Minimum weight to be 2200g (ready to race). Agree


11.10 Batteries to be any commercially available hard cased Lithium Polymer up to maximum of 4s (14.8 volts). These may be installed in any configuration, 1x4s, 2x2s, 4x1s with a maximum nominal voltage of 14.80v. The maximum permitted voltage of the cells when checked at anytime using the section multimeter must be a maximum of 4.2v per cell (16.8v maximum in total). [I]Would like this to have LIHV also because this is already available and why ban?[/I]

All batteries must be homologated by EFRA and must be in the EFRA list. 11.11 The brushless motor (Maximum of 2650kv - 2600kv) and speed controller combination must be or have been previously commercially available and have a maximum Euro recommended retail price (RRP) of 350 euro including all taxes. I think this is an unnecessary rule, max 1950 KV please, and price rule is bullshit

The motor must have a 5mm pinion shaft. 11.12 Speed controller reverse operation must be disabled Agree

BODIES
11.13 Bodies must follow same rules like 1/8th IC cars (see 6.7 to 6.9 Appendix 1).

11.14 CUTS OUTS. One cut out for cooling of motor / esc with max. 30x40mm. Any part of the body cannot be folded outwards to get more air to the motor. It is also not permitted to have a system under the body for conveying air inside the body. Should be left to the driver, unnecessary rule

11.15 WINGS AND SPOILERS. Wings and spoilers must follow same rule like IC cars (see 6.12 Appendix 1).

@ djiewie:
I totally agree with you!
I was not informed about the British proposal with these motor and other limits and I was not present at the EFRA AGM.

At all I am happy the first step to an official rule is done as well as a clear definition modified / stock. We will try to get an adaption to optimize the rules through the year and hopefully can make a fine defined EFRA race at the EURO40+ in Utrecht....

1950kv should be the correct limit for the 4wd pan cars, the price limit is nonsense and the air conveying system should be free - otherwise the fan also must be defined....

Thanks for the support, and wish you success with this adaption, because I will attend the race 40+ in Utrecht.

See you there.

If the max is 2600kv then 1900 should be ok as it is a lower rating ? Higher kv motors such as 2700 are not allowed. They is what my interpretation would be.

I do not understand why LIHV is not permitted? You can allow LIHV and set a maximum voltage like in 1:10th Electric? For 4S that would be fully charged 16,88 Volts...
Motor rule?! Stick to a maximum of 1950kV !

I'm very pleased the majority of the 1:8th pancar racers at our club stick to simple rules:
- Motor: max 1950kV
- Battery: max 4S (never mind the configuration)
- Tires: freedom of choice (no additive, gentlemen's agreement)
- KISS..

@Thomas
If you have the time and opportunity, come and visit our club. We have a nice and very competative field of 1:8th electric pan-car racers.

Kind regards, Freundlichen Grüßen,
Johannes

The new 1/8 electric classes (modified - stock) are integrated in the nitro rules as they are part of the IC section in EFRA. So the electric expirience may be lower.

I will try to publish my proposal to define the stock class in my basic intention to clear and complete but simple rules as soon as possible.

I will be pleased to visit AMCA as I plan to come in late August 2018 to the EURO 40+ in The Netherlands

The rules are their interpretation of how to grow the class. I know in Germany we have a huge push for the Stock Spec 1:8 IC with their spec .21 motors. My son has run this class, and he does very well. On the other hand he also races my Buri with a 2050KV motor on 4S in EG8 and is actually better at wheeling it than I am. We have tried 3700KV SC motor with 3S. We have also test run the Shepherd Velox-E on 6S with the TTB setup, and that was too much.

I do believe the KV limit should be a Range i.e. from 1800 - 2100 because ESC programming can make most very Tractable.

The same with the bodies, restricting openings is a bit rediulous!!! I know we are not building ground effecrs cars here!

The LiHV rule is perhaps, he are affraid, and have no safety knowledge as for dealing with them.

Oh well, I am.just very glad we have an endorsement and a series. If anyhing this class will grow. I just hope it does not go the way of Pro10 in the 90's - Motor / Battery wars killed it off!

+1

If it has the word stock attached to it then get ready for the battery motor war. Thats the problem with any class other than mod these days.

The Stock Spec i am talking about is Nitro...

True, but this class is different. I hate stock classes because of this, I agree.
Most choices should be left to the racer I think will let the class grow. But experience learns that its difficult to deal with higher kV motors temp wise. So for beginners this class is good and because there are not that many setup possibilities, one can be competitive with the experienced racers. At least for the pancars I believe with the direct drive this is.

Speeds are (very) high and so driving skills will end on top. The word stock is there for a little misleading.
