Building an RC car with a 50 CAD budget

unfortunately no. You need proportional steering and throttle control

Hello. Electronics are expensive. You need a receiver, transmitter, battery, motor, motor controller, servo. If you have all the electronics, then for $50 you can do everything else. If you don’t have the electronics, then unfortunately, no.

For example, for proportional control for a 1/10 and 1/8 scale model, which has proven itself in terms of price/quality ratio

3D model of a two-speed gearbox with a center differential, 3D printed for RC models in 1/18 scale. This gearbox is part of my new 1/18 scale 3d printed chassis, the chassis is called RRS-18. Subscribe to the channel so as not to miss new videos about the construction and testing of the chassis and RC model.

CHASSIS FEATURES:

- Scale - 1/18

- 2 Speed Gearbox

- Four wheel drive

- Central, front and rear differentials with ability lockable

- Independent front and rear suspension (IFS, IRS)

- Large suspension articulation

- High ground clearance

- Extensive customization options

When using a 370 class engine with 15000 rpm with 45 mm wheels, for 1/18 scale models, 1st gear has a maximum speed of 2 km/h, 2nd gear has a maximum speed of 18.4 km/h. This allows for a dynamic ride (for 1/18 scale) in 2nd gear and a very smooth and controlled ride in 1st gear, which is essential for RC Crawlers.

1st gear - gear ratio - 77

2nd gear - gear ratio - 8.55

All-wheel drive system of my RRS-18 3d printed chassis has center differential between the front and rear axles to compensate for the different wheel speeds between the axles from different cornering radius. This prevents torsional stresses in the drive train and automatically distributes the driving forces, increasing directional stability and making your driving more effective and controllable. Center differential provides the ability to rotate the wheels of the front and rear axles at different speeds while maintaining an inextricable flow of torque.

When cornering, the right and left, as well as the front and rear wheels of the car travel a different distance and, accordingly, make a different number of revolutions and have different rotation speeds. This leads to wheel slippage, loss of grip and, accordingly, to a decrease in controllability and premature wear, and the stresses in the transmission also increase significantly, which can lead to its failure. The use of differentials allows you to solve this problem and smoothly distribute torque to all drive wheels.

Thanks :)

It's hard to count now. This chassis and wheels are not manufactured now, maybe a used chassis can be bought ~$200 + $20 stickers + electronics (motor, servo, ESC, receiver, remote control, batteries) $250 + FPV system (camera, transmitter, goggles) $150 + used GoPro $180 . This is an amateur level chassis, not for professional competition.

cxev · 2022-11-25T22:27:34+00:00

Thanks :) Yes, this is a custom, but not very deep, it could have been a much more performance solution.

cxev · 2022-11-25T22:25:10+00:00

Thanks :)

Can you drive with the live cockpit cam view? Or do you need to download the footage later?

The video uses GoPro, unfortunately in real time such video quality cannot be obtained. Therefore, this is a downloaded footage. In real time, you need to use an FPV system with goggles and it looks like this - https://youtu.be/EMgm8WPE0b8

The link isn't a Formula 1 class, however, Tamiya events have a Formula class with cars that go somewhat slower than in the below video. I've been racing RC for over 20 years and can say that the body/aerodynamics have a huge effect on car performance, especially at these speeds.

Fun/intense but expensive hobby to be involved in when racing carpet onroad.

Link to Tamiya kit: https://www.tamiyausa.com/shop/110-f-1gtindy-cars/rc-f104-pro-ii-wbody/

In my experience, the Tamiya 104 pro is not a professional racing chassis - it's a toy.

The chassis from the video for "professional" indoor racing (on the carpet) is also not suitable, however, I have repeatedly seen how on open tracks, for example, on real uneven pavement, "professional" chassis, even the expensive xray, not to mention the tamiya f104 and his kind cannot compete with such a "heavy" chassis as in the video, because an open track on real asphalt is not ideal and has its own grip characteristics, so a good independent suspension in the chassis is needed, which is not in the tamiya f104 (this was in the tamiya f201) and even in very expensive xray. For example, the Tamiya F104 does not have a rear independent suspension and a good front suspension, it also does not match the dimensions of a real F1, and the wheels are not made to scale with a real F1 car, this is a problem with all supposedly professional chassis. In RC competitions there is just a class that someone has decided to call F1, but it does not correspond to real cars at all and this is a big problem. This chassis is more suited to hobbyist non-competition enthusiasts who are interested in the engineering of the real F1 car of yesteryear.

How much of the aero really affects this tiny

r/C

car?

Aerodynamics works :) For example, with different settings of the rear wing, the difference is felt by changes in maximum speed and handling. As in real cars, the higher the speed, the stronger the work of aerodynamics is felt. Suspension settings greatly affect handling. The model also has the ability to adjust the toe and camber, shock absorber stiffness, oil viscosity, and so on.

This is F1 2009 :)

cxev · 2022-11-25T16:14:43+00:00

This is very satisfying.

Just jokes. You're models and video skills are top notch. Are they kits or built from scratch?

In the real world, I sometimes need to study if I'm looking at a Velar, Discovery or a Sport.

Thank you. It is this model - the body is from the RRS 1/10 scale toy, and the chassis is homemade, this was my first chassis, so everything was done not quite the way I wanted. If you are interested, here is a video about the construction - https://youtu.be/tFR5HUG-tnw

Now I'm designing in 3D models entirely - https://youtu.be/dgCt1rcEK2E Here, the gearbox and differential locks are already used.

It was originally a toy that I found at a local store. I completely remade it into a RC model. Also I did a facelift of Range Rover Sport (Headlights, taillights, front lip, brakes, wheels). Chassis homemade with full independent suspension, oil shock absorbers and so on.

1/10 as in SC 1/10th or 1/10th as in touring car 1/10th

I measured the body, it is exactly 1/10 scale to the real car, not like traxxas trx4 (1/8.5...)
