B-MAX Competition Frequently Asked Questions:

Q: Is it allowed to install tires / wheels in the opposite direction?
A: Yes. If the tire and wheel size are the same, it can be mounted in the opposite direction, such as with the wheel rim on the outside.

Q: Is it allowed to paint the chassis?
A: No. Painting the chassis would stain the race track.

Q: Can I cut it to adjust the tread of the wheel?
A: No. B-MAX regulations allow wheel machining only to drill holes for shaft penetration. Wheel modification other than the above is not allowed.

Q: Is it allowed to install large diameter barrel tires on large diameter low height wheels?
A: No. Install tires of a size that matches the wheel diameter size.

Q: Is it necessary to install a split bumper like the VZ chassis?
A: No. It is not necessary to install a split bumper or rear stay in the standard state.

Q: Is it allowed to use alternative mesh from other brand?
A: No. Racers must use only the official Tamiya product.

Q: Is it allowed to bend the screw?
A: No. Please use straight screws. If the screw bends unintentionally while driving, straighten the screw.

Q: Is it allowed to glue FRP or carbon plates?
A: No. The original look of the plates must not be tampered.

Q: Trackin Mini 4WD cannot be fastened with front and rear body catches.
A: There is no problem as long as it is fastened with a genuine Tamiya body catch.

Q: Is it allowed to remove the front cowl?
A: Yes. As long as it covers the wheel and cutting the cowl is not allowed.

Q: Is it allowed to remove the wing?
A: Yes. The wings can be removed and the wings of different models can be installed.

Q: Is it good to put the body low?
A: No. Body catch modification is not permitted except for trimming.

Q: Is it allowed to reduce the claws of the body catch and the backlash of the receiver?
A: No. B-MAX GP is based on the concept of unmodified regulation as much as possible. Therefore, please do not modify it.

Q: Is it allowed to make a hole in the MA chassis to remove the battery?
A: No. Chassis modification is not allowed.

Q: Is it allowed to cut where the body plate or mass damper hits?
A: Yes. However, modification that significantly changes the shape is not allowed. Please be careful when modifying the body.

Q: Is it allowed to modify the body to reproduce the manga?
A: Yes. There is no problem if it is a kit (body) that Tamiya gives modification advice in the instruction manual etc. Please note that other than that, it may be judged that the modified changes the shape significantly.

Q: Is it allowed to modify the gear?
A: No. It must comply to official Tamiya Mini 4WD regulations.

Q: Is it allowed to put a figure other than Tamiya made?
A: No. It must comply official Tamiya Mini 4WD regulations.

Q: Can I paint the plates?
A: No. FRP or Carbon Plates must retain it’s original look and form.

Q: Is it allowed to combine tires and wheels with different widths?
A: Yes. However, it is not allowed to adjust the width of tires and wheels.

Q: Is it allowed to embed 520 bearings in the standard plastic rollers of the kit?

• Racer’s name and/or number will be called for stand by using random draw for each heat.
• Only the racer will be allowed in the stand by area. 
• Marshal’s Call to Pair – Pairing Marshal is given all authority by TM to pair racers according to his prior knowledge and judgment call subject to the rules of Tamiya with special consideration for same team conditions if it is a team based competition or class/chassis based if it is a class/chassis-themed competition. 
• Racers are not allowed to calibrate brakes during stand by.
• Racers are allowed to tighten loose screws and nuts during stand by.
• Racers are not allowed to remove the cowling of their race cars, to manipulate their batteries by removing them, to oil their motors, tighten brakes and screws using any tools or devices.
• Racers are not allowed to release their cars on the race track as a form of practicing once the race has begun. As with any other violations listed in this rules, the racer’s car will be subject to automatic disqualification with no remorse.

START OF RACE

• Racers are called at the starting grid for each race of that heat.
• Racers will draw a number on which lane they will start.

WINNING CAR

• Car that finishes the required number of laps first wins the race
• All four wheels of the winning car should cross the finish line to be declared as winner.
• Dead heat rule applies during the race and subject to the declaration of the starting marshal.

• Any car reversing in any part of the tracks is immediately declared as DNF and will immediately be removed off the race tracks. In a banked portion of the tracks, once a car back tracks, reverses or slows down, it is automatically considered DNF and is immediately removed from the tracks.
• Slow but moving cars will be considered DNF if the lane it occupies will block the faster cars. This also known as a lapdown. If there are only two cars in the tracks then the faster car is already considered the winner if it is hit by the slower car. If there are three cars in the tracks then there will be a re-race between the faster car that was hit and the second faster car. The slowest car that caused the hit will be removed from the race.
• Racers conduct will strictly be implemented specially in the track area. Improper conduct is not tolerated and can cause disqualification of the racer.
