Oapr Lmp Class (Questions)

Recommended Posts

Hi Peoples ... hope I am not being to naive asking dumb questions. But the fact is I have been out of slot car racing so long and now wish to get back in. So questions may be a bit naive, or even downright obvious and any fool would know, but not this fool.

 

First: OAPR LMP class.

 

In the rules it says the body must be 15 thou imperial. But the nearest in millimetres is 0.5mm

1 .. This would mean a 0.5mm body was 19.7 thou ... would this still be within '15 thou' or illegal ?

 

2 .. Does the class allow any body-form from the Le Mans that raced since 2000 ? or only from 2008, but livery may be from 2000 but not body ?

 

For example this car raced LMP (unsuccessfuly I believe) from 2000-2002 ... would this body be allowed ?

3 .. If the above body is legal would anyone know where it could be purchased in 1/24 ?

 

4 .. Does anyone have a list of exactly what bodies are allowed ?

 

I have many more questions but probably enough for now!

 

Thanx in advance ... Greg

Nobody will object to you using thicker material.

No it is not allowed, the rules state:

Any true 1/24 scale representation of a 1/1 LMP (Le Mans Prototype) car that has raced in the American Le Mans Series or the European Le Mans Series from 2008 to 2013.

 

3 .. If the above body is legal would anyone know where it could be purchased in 1/24 ?

 

4 .. Does anyone have a list of exactly what bodies are allowed ?

 

Here is the latest homologated body list:

- from Patto's; the Peugeot 908, Aston Martin AMR and the Audi R18.

- from EE.au( contact me); the Peugeot 908, Lola Aston Martin, Lola BT70, Acura, Audi R10, Audi R15, Audi R18, Porsche RS Spyder and Pescarolo.

If anyone has a body they would like to include, please let me know and we will homologated it if it fits the specifications.

 

I have many more questions but probably enough for now!

 

Thanx in advance ... Greg

 

Please refer to discussions that took place in the 'Special Events' section - the Qld Enduro Champs. That is also were you will find the latest ruleset for this class - see top of page 3.

 

Thanks for asking, this way we all get on the same page.

 

Cheers,

 

Jan
