Thank you for this

Yes, I'd wondered why my AR Tuned Build was performing faster than most AR setups. I didn't realize that running two different compounds had a significant difference in overall speed.

I've currently only got the Junior Japan Cup circuit and am building a bigger track. It seems corner speed and stability on the lane change is the key, this may be the secret weapon :)

Very cool. Using the last configuration will definitely increase overall speed. If you start flying off from your lanechange, you may need to start increasing the angle of your front rollers.

While I do agree that it would have been more definitive to have averaged runs, there were some other reasons that I had to consider in choosing to run the test the way we did it. I had to get there early enough so that I didn't get in the way of other customers so I had some self-imposed time constraints. So that forces me to use Alkalines since that would minimize the time to run the test. If I had chose to use NiMH the test would have taken much longer due to recharging the batteries to the same voltage every run. The motor also starts to change in performance the more runs you put it through. If I were to give each configuration a total of 2-3 runs that would increase the number of laps the motor would run from 12-36. The motor will heat up, carbon will build up, list goes on. I didn't want to have to clean the motor after each run. Which goes back to time constraints again. I've always wondered about the one way wheels as well. Good idea mate, don't be surprised to see a video like this in the future. I probably wouldn't bother with testing different sizes of the one way wheel sets. I'd narrow it down to just using mediums to see if there's a big difference. The track would also need more corners. But yeah its definitely a good test to see if the benefit of having a differential in the corners would outweigh the extra weight and possible reliability concerns.

Getting them set up properly is the hard part. You need to pierce the big gear in the wheel but not the face plate, then attach the wheel and gears to the shaft before attaching the face plate, this will get you the best fit with out the little lateral play they tend to have. You may also need to trim the wall the middle gear sits on in order to have the wheels spin correctly, I find sometimes they have a bit of resistance if not sanded a bit.

Drew Fox me too I love using them for tech tracks.

D'aww, Uncle Jan. When are you guys due?

Yes, that is correct. Consider a couple of things though. Running the same test 10 times and then times 3 takes considerably more time. In addition to that, it also requires 30 sets of new alkalines. Which I do not have nor care to spend the money. If I use rechargeable batteries instead, the process takes even longer! If you run the motor that many times, the performance starts to change and will affect the result, which adds another variable that we do not want. My prediction is this, even if I ran each tire setup 10 times, the difference to itself would be around +/- 1% Which can be considered negligible.

There are too many variables and in order to minimize those variables I chose to give them 1 run each. And as you saw, there was a clear difference in each configuration just from 1 run each.

Thanks for the reply point taken, off video topic question, do you have a video explaining roller angle effects? like what is the general angle to overcome 3 lane bridge, slope + curve etc. I know that will be depending on the track layout, your build etc, if you can just kindly give us newbies a rule of thumb regarding this. Thanks!

I generally stick to 5 degrees when I use 19mm HG rollers at the front. I usually do not go below that unless the lanechange is in a very slow portion of the track. But then again 5 degrees still handles more power so I'd still stick to 5. If you start flying off at the lanechange with 5 degrees try and increase to 7. If it still flies off, start praying to your God.

Thanks and well noted! I always do the later. haha

Good question. For super hard and low friction. I have not in the same manner as these non trimmed tires. But jave have used that combination in many of my Open Class builds. Check them out on my instagram. Link is in my KZfaq Bio. For Super Hard and Hard, i have them on my AR Chassis Basic Build Car. It is pretty fast. And I will do a comparison video of my basic build of MA, AR, and FM-A soon, so stay tuned to the channel.

Z3N Bluster ok im wait for ur next video...

I don't understand your first question. A higher gear ratio like 4:1 has more torque, but less top speed. A lower gear ratio like 3.5:1 has less torque, but more top speed.

I think what he means is, what is the proper thickness of the brakes?, how mm it should be ?.. and is that any relation with the gear ratios... lets say if we want to change to high gear ratio, should we adjust the thickness of the brake... CMIIW...

​​no general formula for this one and no direct correlation (like thicker brake sponge means you have the up the gearing). You will have to assess and imagine the effects of each brake thickness as well as the gear ratio on the track layout. Use the vacant time before the competition starts to plan how you will tackle the course.

You should get the Large Diameter 5-spokes and have tires trimmed for those. If you can't do that, use Medium Diameter wheels.

Its up to you. it depends on your budget. I highly recommend the AO620.

It sounds to me like a high speed track. if there are no jumps and youre using a rainbow lanechange. Use Jet Dash. If you dont have a Jet Dash, use Ultra Dash.

No, I don't use Reston tires.

ah its not popular anymore due to super hard tires

No. The chassis on this car is MA. You're not allowed to use Power Dash on MA.

Z3N Bluster i build my MA car like your car but i change my gear to 3.7:1 and use mach dash..is that good jan?

Uden Beater bcause power dash is single shaft motor dude

ashmo That's probably too much power dude. Maybe Hyper Dash at the most. The MA car is built for Tuned Motors, so try not to wreck your car with Mach Dash.

Z3N Bluster Okay then,if i want to use Mach Dash at my MA car, what would i need to modify up to final form like, chassis cut,hanging damper, trimmer wheel, and build suspension?

No

Thx

May pambili na kasi majority ng batang 90s eh hahahahahaha bumili nga din ako.... Dati dun lang ako SA 60 na peke eh

same...bumili din ako ng starter pack na ROWDY BULLY naka atomic tuned 2 na..para kunti nalang need upgrade

Matagal na uso tamiya mini4wd sa pinas dude...

@@mineralwater25 bro he said nauso. Meaning it returned. Anyway. The brickyard in Glorieta is pretty cool

Medium Diameter Wheels.

I remove the covers on all my 620 bearings. The cover slows them down anyway.

@@Z3NBluster I thougt it'll be more prone to dust

Yes, but that also makes it easier to clean. The question is, do you want a slower car that doesn't have dust in its bearings? Or, do you want a faster car with bearings that are easier to clean?

Blame the KZfaq Algorithm :D

They should be trimmed. They regain alot of grip when they are trimmed.

I don't understand your question.

@@Z3NBluster sorry i mean the velg sir

What is a velg? I've never heard of this word.

Velg means rims

Super Hard generally.

The general knowledge is. Medium Diameters have less top speed, more torque, and lower center of gravity. Large Diameters have more top speed, less torque, and higher center of gravity. People generally trim large diameter tires to get the better center of gravity like medium diameter and also lose weight by having less rubber on the wheels of the car.

Z3N Bluster so conclusion is medium tire is better

Michael Kenny Depends on the rules. If you're not allowed to trim your tires. Use Medium Diameter in a technical track. If you're allowed to trim tires. Use trimmed large diameter.

Z3N Bluster owh i see... okai thanks for the information 😉👌

Sounds like you were racing on a high speed track. The track in this video is a technical track. It has slopes. The car setups required to maximize performance on these types of tracks are completely different from what you're describing. We race high speed too but we limit it to Tuned Motors. Here in the USA, it would be too dangerous to run very fast cars. If it flies out and hits somebody on the leg or worse, somebody will take you to court and sue you.

Z3N Bluster I recently got back to racing them again. Before I started, I was oriented about The three different classes. Pro-stock, speed-tech, and as you mentioned - high speed. At that Time we just want to be fast so my first true build was a high speed build. We didn’t have to deal with bumps. We didn’t deal with damping weights which didn’t exist back then. As a kid back then, I always was a bit scared everytime I ran The car. Ofcourse a car moving at those ridiculous speeds is no joke even my uncle was blacking off The track. The “oomph” you get from highspeed can’t be felt on pro stock and speedtech. But speedtech gave me The most headache. People don’t race highspeed in my country nowadays.

Luky H4rr13r Yes but the car will be more likely to bounce out. I'm not sure if you noticed, but the All- Hard Tires configuration bounced more than the others.

ill go with slick tires.. soft but thin.. you will hae to depend on the breakpads and side dumpers with stiff

Nope

Z3N Bluster idol maganda ba yung revtune 2 para sa ganyang setup? nag build kasi ako ng MA ginaya ko yung nasa video mo. ganyan na ganyan. and sa gears po pala anong magandang substitute for 3.7.1? ... I super like your builds.

Wag mo gayahin Yung ganto. We only tested the tires on this video. Use Medium Diameter wheels instead. Use Torque Tuned 2 Pro.

Use 3.5:1 if the track has alot of straights. If your on a more normal 3-lane track. Stick with 3.7:1.

Call them Medium Diameter, so everyone is clear. Yes. The center of gravity is low yet your top speed isn't going to suffer too much. If you you use Small diameter you risk having too low of a top speed. If you use Large Diameter you risk having a car with too high of center of gravity. Talk to your fellow racers to see and find out their reasoning as to why they use certain parts. We do not race, "Pro Stock," here in the States so I can only help you to a certain extent.

+Z3N Bluster thank you sir :)

Too much bounce and too much grip.

It sounds like you have underlying problems that sort of relate to your gears. If your Ultra Dash is slow. You may need to break-in your Ultra Dash or you need to work on making your transmission smoother. If your car is very loud, you need to work on your transmission.

are you filipino z3n blaster?

No.

@@Z3NBluster can you tell me the name of that product?

Tamiya Part Number 95371

@@Z3NBluster thank you very much

Instead of the Extra Large Diameter setup that I demonstrate here. Use Medium Diameter instead.

There is no best motor for Tamiya. It depends on the track. Always adjust your car to the track for racing. There isn't a motor that will be good on ALL tracks.

I heard Indonesia still has alot of Medium Diameter Low Friction tires.

We talked about that in the video. We said that the results skew towards hard tires, is probably due to the track configurations.

I would have.. Too bad you misspelled, "Buy." :D

You mean the distance between my rear brakes and the track surface? There is no ideal distance. You need to change your setup according to the track. If there are alot of bank sections, your car will slow down too much unless you raise your brakes. If the track has many short length jumps, you need to lower your brakes.
