So I came into RC cars from drones. In the drone hobby we use something called bidirectional dshot so an ESC can know the RPM of a motor. This leads to a predictable throttle response where a certain throttle value is directly equal to an rpm speed of the motor. Coming over to RC cars I had no idea that lots of brushless rc cars suffer from poor linearity between throttle input and motor RPM. So what's a good way of getting a really linear and predictable throttle response? Because I am filming RC crawlers and trying to keep them in shot. Holding a camera in one hand and the controller in another. I basically need a motor and esc where a certain amount of trigger pull is directly related to a specific speed of the motor. Like on a drone. Do brushed motors suffer from this? If I go brushless do I need to go sensored?

Hello, I started my Youtube channel about 2 months ago so still quite new. 😁 Taught myself to use a camera and edit for the first time around that time too. Learning and trying to see what works and what the audience likes. I didn't plan it this way, but most of my content is RC boats. Here's my channel https://www.youtube.com/@ChinaExpatsRC And here's my latest I made yesterday: And yes, it is very hard to get exposure starting out 🤣 As a Youtuber you pretty much have zero say over who Youtube recommends your videos to, You just have to kind of hope and pray that you get identified as an "RC channel" quickly by their AI algorithm and matched with an "RC enthusiast" audience. I don't think I've been identified as one yet.

Stock is a 280 brushed motor. I stuck a 370 which is sold as an upgrade. At first everything was fine. But I started to get random uncontrolled reversing at full speed without throttle input. This would happen when I changed the steering or throttle rate. It's now progressed to either just full speed running the motor as soon as the car is turned on. Or not driving the motor at all when the throttle is pulled. It seems like a remote issue because the motor only spins by itself when the remote is turned on and connected. Does anyone know how to calibrate these 2-in-1 ESCs or solve this issue?

Here's my cheapo A HQ727 which is a Slash clone. Running a 3660 brushless motor. I built it myself and designed the body. It should be able to run 4s but 4s eats spur gears.

The creator of the first video Hoonsrc goes into detail here about how he films. Most of his stuff is slowed down 0.5. But he doesn't explain why the sound does not sound slowed down. I tried to shoot some test footage. But the sound has a very obvious "slo-mo sound" in the background. (I also don't have a gimbal yet) https://youtu.be/pNnMKGSw6XU

Sounds like a lot of work. When the video is slowed it will become double the original length, but the audio will not. I guess they need to repeat sounds to fill it out. Or record B roll sound to dub in.

Ha ha yes, the Chinese stuff makes more sense when you see what the Chinese prices are. You can forgive their flaws more. Some of the stuff is 50% or more cheaper. I've got this cheapo MN99 a 1/16 Land rover D90, had a guy in the US want to buy one in another community and we found out they were $100 on banggood, I bought mine for $35 😐

I've recently come across a rabbit hole of these kinds of Korean scale truck videos on youtube. I already know how they are filmed, they use a 3 axis gimbal, shoot at 60fps and slow the footage down by 50% to make the vehicles seem more weighty. But how do they do the sound? I shot some test footage and the video sounded slowed down. I don't think they're using an engine sound module, as the noise is not constant, it's only heard when the RC is moving. Is this just the mechanical sound of their RC car being picked up by a good microphone?

Does this count as a scaler lol?

Hello everyone. I'm a British bloke that's been living and working in China for the past 5 years. Recently got into RC Cars and Boats after being into quadcopters for a while. I love my cheap Chinese RC like WPL and WLtoys 🤣 Hoping to meet some interesting people and talk about RC.
