International Race Kampenhout GRAND PRIX   2015 – briefing


About practicing

After your practice run, please stay at least 5 minutes on the track for marshaling your friends… and other competitors J.


Race duration is 5 minutes. Every driver will race 4 qualifying rounds and 3 finals.

Line up beside the rostrum a few minutes before your heat (pass behind the rostrum!). Wait for the “race over” call of the previous heat. First all the drivers come down the stairs before drivers of the following heat go up.


After your heat do not forget to shut off your transmitter and bring it to technical inspection together with your car. Proceed directly to your marshaling position.

Marshals stay on their position until the replacement arrives!

After marshaling you can collect car + transmitter.


Important: make sure your transmitter is recognizably labeled to avoid mistakes when you pick up your transmitter after marshaling.


About racing:

– round by round, two best results to count

– starting order first round by lottery, then according to results of previous round

– in the first round you can do two laps as warm up to check your transponder by driving over the loop

the straight is a go slow area during warm up lap and after “race over” call

– starting grid for all finals chosen by pole sitter A final


During qualifying, let the faster drivers go by. No shouting on the rostrum (or elsewhere), be a gentleman at all times.

Marshals have to wear the fluo vests and solid footwear. Marshals are allowed to do a quick fix if needed (refit loose ball cup) whilst still keeping an eye on the other cars on the track.

Don’t drive in the opposite direction.

No drivers or mechanics on track before the “race over” call.

If your car breaks down during a heat, stay on the rostrum until “race over”, bring your car and transmitter to technical inspection and go to your marshaling position before repairing your car.


Lower finals may be run with 11 drivers to avoid an extra final with only a few drivers.


About penalties:

Warning or stop and go 5 seconds in pits at the end of the straight.

Failing to marshal = loss of best result of the day.


Practical information:

Car numbers are to be collected at timekeeping (near rostrum).

Number stickers: one flat on the front windscreen.

Marshaling order on timetable.


Parking and pitting:

Absolutely no race related parking near the playground/kitchen area.

The parking area near the track will be used as pits, so park your car further down in the park to both sides of the outer road. Do remember to keep this outer road free for safety regulations.


On Saturday and Sunday afternoon the entry/exit of the Park might be blocked due to ongoing activities.


Please keep the premises clean, bin bags are available at timekeeping and catering. A skip is placed near the school building.


Enjoy your race!

Camping in the park is exceptionnally allowed from Wednesday on at a cost of 3 euro per person. Basically it is bush camping, there are no showers. You can bring your generator, but use it wisely. A central power point will be installed next to the pond, bring a solid extension cable. If you need more information about the type of electrical socket we have in Belgium, check the general info again. Oh yes, nights will be noisy in the park because of the ongoing festivities. Need we say you can always join the party!
Park your car left or right of the road, for safety regulations the passage needs to be kept free. During the park festivities entrance and exit of the park might be blocked on Saturday and Sunday afternoon.
The date of the nearby rock festival at Werchter has been forwarded one week, so for once trafic and hotel occupancy will be more “normal”.

General Info


Hello GP drivers,

Thank you for your entry. Here is some general info about our 2015 race.


The MBV track is situated in a public park behind school buildings.

Address: Park van Relst, Aarschotsebaan 128, 1910 Kampenhout (Relst).

The track has an astroturf surface. Jumps? Oh yes, a 90° table top, whoops, a ski-iiii jump, a fabulous “wall of death”, two cobble stone sections,  a tricky off camber turn, …

Special feature: unique underground drainage worth seeing. Drainage holes and pipes under the track lead to one collector on the lowest point.

The rostrum along the straight is more than 2 m high. Lap counting is installed underneath.

On the parking area right next to the track tents will be put up for pitting. Some drivers prefer pitting in the camping area which is also close to the track.

An average lap is between 27 and 29 seconds. Highest grip when the track has dried after it rained, slippery when wet. Prolonged dry weather results in slightly slower lap times.

Yes, we know all that, but what changes did Willy made this year?

The main jump has been moved to the “hoechelenkant”. The wooden washboard is in wood heaven now. The wall is covered with thicker astro. And really new is the flexy fence all around the track.


Schumacher Mini Spike 2, all types, all compounds for the driven axles.

Additionally for the 4WD front wheels the Schumacher Wide Stagger Rib (all compounds) will be allowed.

Cut and shut not allowed.

Recommended compound for dry weather:  yellow .

Recommended compound for wet weather: silver.


LiPo: 7,4 Volt originally hard cased LiPo’s.

Use and charge according to manufacturer’s instructions. Liposack recommended for charging.

Charge regime CC/CV, maximum allowed voltage setting on charger: 8.40 V or 2S.


No motor limit, brushless (to EFRA specifications) allowed.


2wd 1474 g,

4wd 1588 g



Friday: registration and free practice,

Saturday: 8 heats 2wd

Sunday: 7 heats 4wd

Timetable and briefing will be sent the week before the race.

4 qualifying rounds and 3 finals for everyone

race duration 5 minutes

round by round qualifying, 2 best to count.

RC4 decoder (hand out RC4 PT available if needed). MRT transponders probably won’t be fully compatible with an RC4 decoder.



You can search for hotels near Brussels, Leuven or Mechelen.

Camping Veronique is only 3,5 km from the track:

Camping Trianon Hever,  8 km from track:

Camping in the park (3 euros per person) during the event is exceptionally allowed by the Council from Wednesday on and at own risk. The park is not a fitted camp site, there are no showers (only showers provided by nature), limited 220V from Friday on. You can bring a generator but use it wisely at night. Keep outer road free. Do not leave valuables within grabbing reach. And don’t count on quiet evenings, especially on Saturday night there will be loud music in the big party tent.

This is a link to the local festivities:


Type of electrical sockets used in Belgium:

or search Google for: CEE 7/7

Power 220V supplied in the pits. In the camping area there will be one centralized multi socket, so bring your own good quality extension lead.

If for some reason you cannot attend the meeting, please let us know as soon as possible, as there are still drivers on the waiting list.

See you soon,

Willy & Liliane,

MBV Kampenhout.

Update control tyres Kampenhout International Race:

For 2015 we will have as control tyres (on driven axles) the usual Schumacher Minispike 2 (all compounds).

Additionally for the 4WD front wheels the Schumacher Wide Stagger Rib (all compounds) will be allowed.

A good opportunity to test these tyres as they are also the control tyre (in yellow compound) for the World Championship.




Our 2015 GP will be held on the first weekend of July, coinciding with the park festivities as usual. It will be on the Efra calendar as International Race. However the format will be the same as before and an Efra licence is not required.


free practice on Friday

2wd on Saturday

4wd on Sunday

Control tyre for driven axles: Schumacher mini spike 2, all types all compounds.

Entries will stay open  from the 9th of February until the end of February.


By sending your name and class(es) raced to, you can apply for a place.

Everyone can apply, even without personal invitation.


You will receive a confirmation for the entry or reserve list after the end of February. Payment details will be in that mail. Do not send any payment before this confirmation with payment request.
