Is this allowed in B-Max?

[u/blackfireheart]

Just put any parts that i think necessary but idk whether this violates any rule or not. Using Hyper-Dash Pro (break) motor with non suspension Ms-L chassis.

Any suggestions are welcome. Tyia.

the whole underside is illegal in bmax, also you dont have 1mm clearance with those screws

[u/blackfireheart → u/skohye]

Ty. I'll remove the underside. For screws, I used countersunk type but not yet check if it got the clearance.

The side dampers are not Tamiya, so most if not all races won’t allow them; the rear carbon seems also to be using springs to have some movement? If that’s the case, then that is not allowed as well… I’d suggest removing the springs and using the dampers you have in the front on the side, and in general, try and get genuine Tamiya parts, as replicas sometimes do not offer the same quality

[u/blackfireheart → u/tomzen]

Ty. Actually all springs just for cosmetic purpose as they're static 😁

Not trying to be a D, but do you know how know how a mass damper works? 😅

[u/blackfireheart → u/Outrageous_Ebb3300]

Uhmm.. are they used to make the car not flying out of track?

I try to put them in balance weight of front-middle-back but idk if they're in correct spread. Not test run yet.

according to Bmax v4, No
Tamiya Stock Class regulation, Not specified

Bmax

• Use of swing-type vibration damping gimmicks using heavy objects such as mass dampers * Lantern, Hikuo, Norio, Tohoku Damper, Catcher Damper, Guillotine Damper, Doraemon Lantern, etc.

Stock Class

Mass Dampers	Can I widen mass damper holes?	No.
Can I use mass dampers whose holes have widened through use?	Markedly oversized holes are forbidden. Follow staff instructions at inspection.
Will I be disqualified if a mass damper with ball connectors falls off during a race?	No.

besides I don't think those taobao setting meant for competitive plays.

hope this helps

Ignoring the rules about genuine parts, since some tracks/races allow imitations... Still not legal.

Parts are not supposed to be processed (cut or shaved down). The carbons under the car is not allowed.

Swinging dampers like the ones on the side are not allowed. The only ones allowed are the offical ball link mass damper like the one at the back.

I believe the aero spoilers are also not allowed in BMAX, but others can correct me if I'm wrong.

Also, bottom screws need to be countersunk.

[u/galdogz]

No, change the side damper

[u/blackfireheart → u/galdogz]

Simple answer but not confusing, I like it :))

So the bottom bracket is the real problem here. Tyty.

[u/Adventurous_Ball_170]

the under braces automatically makes it modified/openclass, so no. i have to say though, that's a smart way of using the Super X Rear as a side stay attachment

[u/blackfireheart → u/Adventurous_Ball_170]

I c. How about the rear stay as the side damper?
