Hello guys and sifu. Super noob here.One noob question. What screw set needed to mount roller bearing on hg for speed set up?

Well, the rear brake skid comes with the stock kit is made of low-friction POM plastic (as with the plastic bearings), so it will have less wears than the others.

By the way, I have somethings to asks: What is the difference between the normal rubber tires and the silicone tires? And what's the difference between the normal tires and the trimmed ultra-low-profiles tires?

Also I recently noticed that all Tamiya motors that are made by SMC motor uses carbon brushes. (This includes the Sprint-Dash Motor my old Max Breaker have) I wonder what's the benefits with the carbon brushes compare to copper brushes.

Silicon tires warms up faster thus having more grip compared to rubber. But if you have a long circuit and the silicon tires are not taped it might come off easily once it warms up (getting loose). It's okay for lower speed layout with many jumps or uphills, but the advantage is not by much.

There are a few different reasons we want to use low profile tires.
1. Soft rubber tires are generally bumpier especially when combined with plastic wheels. Trimming it to low and absolutely flat profile it gives more surface area which is more stable when landing from jumps.
2. Reduce overall wheel+tire diameter for lower center of gravity and slightly faster acceleration

Carbon brushes wears out faster than copper brushes, but the more it gets worn, the better it performs (more surface area touching the terminal) until the carbon finishes.

Ah. Now I understand how those works.

By the way, since I stays in Ipoh, I have a question to ask: is Tamiya Unlimited Trend Store at Ipoh Parade still exists? If not, what about the Tamiya 4WD Ipoh Underground store at Complex Yik Fong?

I ask this because tomorrow I will go there to buy a new Mini 4WD car with either the MA or AR Chassis. (if lucky, I might get the Shooting Proud Star I wanted) And don't ask me to go to Taipoh store, because me and my relatives doesn't know where the shop is.

Edit: Nevermind, I found both shops to be alive well, though I have to buy the new car (and the new FRP plate) from the Tamiya 4WD Ipoh Underground store at Complex Yik Fong as the Tamiya Unlimited Trend Store at Ipoh Parade haven't open yet when I arrived there.

While I didn't find the Shooting Proud Star, at least I found and brought the Beat Magnum Premium and replace my old Max Breaker as my current car. (Due to the fact that while I am at Ipoh Parade, I did a test run on the race circuit but my Max Breaker's rear wheel become loosen and eventually comes off! What a shame.)

How do you know if it is silicon or rubber? Or are you referring to the Pneumatic tires? Are XL tires trimmable? They seem low profile but still bouncy on tracks

No. He's referring to the silicon tires, not pneumatic tires (which no one uses right now). Anyway, all the low-profile tires from Tamiya can be trimmed, but I am not sure about the other makers'.

Anyway, here's my Beat Magnum Premium with all the GUP attached.

All Invited !!

I have used 2 lane track but not original Tamiya selling RM 200 for 2 set..

Boring la semi tech. Anybody playing Sotong Speed on the 31st?

Well, post a pic of you winning using those brakes then

Seriously, I am really fat and I am wearing eyeglasses if you ask me. And honestly, I don't think anyone will dare to challenge me because my car is somewhat slower than their's.

Anyway, I trimmed the tires a bit to be flat so it will always have max grips. And...I planned to buy a Power-Dash Motor and the carbon pinion gear pack as my old Sprint-Dash Motor is finally broken.

so is the brakes up to racing spec or not

Well, if you mean braking power, I will say not much unless you add the sponge tapes on it. In fact, I am going to add the sponge tapes on the brake skid AND the old frp plate I attached to under the front bumper.

Heck, I hate to say this but there's times where my new car had either course out or flipped on the end of the lane-change section of my own 2-lanes junior circuit at my home because it going too fast.

Don't play 2-lanes

I hope I can go to Ipoh Parade to do practice races anytime I wanted, but I can't because my family are busy doing their own things and I have to take care of my grandma who had fractured her own right arm and hasn't healed yet since a half-year ago.

And my room is too tight and isn't large enough to place a 3-lanes junior circuit and I don't think my family will allow to place the circuit on any place in my house other than my room, so buying a 3-lanes circuit is out of option right now.

Tak tanya pun. Point is. 2-lane LC is tighter than 3-lane. You are only encouraging yourself to play slow

I see.

By the way, I read somewhere on the internet that the full potentials of Sprint-Dash Motor and the Power-Dash Motor can only be reached by using the certain rechargeable batteries (like Tamiya Neo-Champ batteries and Panasonic Eneloop batteries). Is that true?

Takes no Sherlock to know a 1.3V Ni-MH performs greater than a 1.62V Alkaline bro
