As the silicone with the cornstarch is very thick, the best solution I found was to spread it like this, I couldn't just pour it in, so I made the mold with that in mind.

Thank you very much for your comment, after several attempts this was the best solution I found, I tried using some materials to soften the final rubber but I never had good results, and as I was going to use it on tarmac it was good that it was harder and more resistant. If you find out what the material is, I'd love to know. Thanks!

It is closer of a 1/10

​@@3dimensions478 thanks for the design.. im on my progress to complete the print

Thanks!

In the past I used the same method, however with silicone I have a lot more grip.

Thanks, in the next projects I'll try to improve the process.

I used construction silicone, I don't know if the results will be different with others

@@3dimensions478 ok thanks.

No, I designed the molds myself, but you'll certainly find similar toturials on youtube

27.8 kmh = 17.27 mph Top Speed

All the electronics I used are in the instruction manual in the description link.

This is amazing I’ll be printing this today

I shared the files in the last video on the channel.

@@3dimensions478 thx u

I used silicone from Soudal and cornstarch from a Portuguese brand.

Thank you! I have never used foam tires so I can't compare, compared to rubber tires the silicone tires have more grip. The biggest disadvantage is the lifespan, they last less time, especially on very rough surfaces, however I have tested on concrete and asphalt and they didn't show significant wear.

Have a link to the 3d mold model?

I will use these tires and rims on my next RC car, I have already finished it but still need to record and edit the video. When I post the video I will make all the STLs available.

I didn't put a differential in this car because as it is off rod it would sometimes cause it to lose traction in one wheel and that wheel would be spinning non-stop without moving the car. And with a differential lock it is more fun to drive on loose ground. The A2212 is my favorite motor for small cars, cheap, powerful and reliable. I found an ESC with reverse for just over 20€ and the programming possibilities and braking make it a good buy.

No, I just have a 2S and so I only used that one.

@@3dimensions478 oh okay i have a motor like this but im running 3s and it gets pretty hot. how hot does your motor get (aproximately)?

@@lucasvanhamburg4937 It is difficult to quantify but the engine did warm up a bit, but it was much less than in cars, for example.

@@3dimensions478 so I thought

Thanks, in this model you should use the best orientation to print each part, for example to use less support material.

Thanks! Yes, the differential bases are inspired by the Tarmo4, I really liked the way it's possible to remove the differential without disassembling the whole front axle so I decided to make my version. And yes the TPU shocks hold up well, when I'm not using the car I leave it with the wheels up, more properly I support the chassis on a roll of tape to prevent deformation in the shocks.

anything from 30 amps and up should work. get one for a car if you want reverse

I apologise but I never made the files available. The car gave a lot of problems and the final result was bad so I didn't make them available so no one would have a bad experience.

Try "stretching" the bevel gear on your slicer to increase the Z axis dimension a little. If it doesn't work let me know so I can change the STL and then send it to you to fix the problem.

3Dimensions yes please can you change the stl and paste it in the comments please that would be great thanks

@@dopesongsrimix5620 Send me your email by message on Thingiverse.

3Dimensions sure

@@dopesongsrimix5620 Did you send anything? I didn't receive anything.

Thanks my friend! Glad to hear it! Best regards

Thank you very much! The tip I have is for you to watch a lot of videos of other projects and also some "real" rc cars to have a good base and an idea of the kind of car you want to build. It is very important at the beginning of the project to already have an idea of what you want to do so that everything works together properly. Some weeks ago I tried to make a rc bike but I didn't have the expected results so I didn't release the video, but one of the parts that surprised me was the transmission, I used two belt pulleys in PLA and one belt in TPU and it worked very well, in the future I will try to make a car powered by a 3D printed belt.

@@3dimensions478 Thanks for the reply! I already looked at many rc vehicles and real cars. I also design a Mini Speedtank, but it has no suspension and a really simple gearbox. Although it isn't to complex, I spend a lot of time in CAD. Also started three times from scratch :) I think I will start with the rear axle, print it out and look if it works. When you had a good experience with TPU I'm not that afraid trying it ^^

And i have new tyres

Glad to hear you liked it and would love to see the end result! I have never used another engine but I think 4300kv is too much, maybe between 1000 and 2000kv is best, if you have too much power you can break transmission parts more easily.

3Dimensions ok can is make the structure any stronger cuz i was hoping this car would support the motor

I already have ordered the motor so

3Dimensions ok now im talking 3100kv

Thank you very much and I'm glad you enjoyed the video! I changed the extruder to a dual gear and can print flexible filament with some quality. When you finish my project I'd love to see the final result! Thanks again.

As long as the dimensions are the same it can handle it, you can for example use a motor with more Kv and you will already increase the maximum speed.

3Dimensions can i use different size motor like the 3900kv ones? If that was possible it would be too good

@@dopesongsrimix5620 If the dimensions are the same you can use it.

Its diameter is a bit larger and the length but can i adjust ?

@@dopesongsrimix5620 I'm not sure if that engine fits but you can try.

You will need various types and sizes of bolts and nuts. All measurements and quantities are in the instruction manual.

Thank you very much!

Thank you very much!

Thank you very much! I know that if I used the suspension and tyres not 3D printed I would have a much better performance, however my goal is to make the cars with all parts 100% printed, obviously without the screws, bearings and electronics.

Hi, all the parts and dimensions are in the instruction manual but if you want I can send you the links I used, I bought everything on aliexpress.

@@3dimensions478 yes pls that would be great
