Simple.. Direct.. To the point.. Easy to understand.. A fella could not POSSIBLY have asked for a better instructional! I have saved this for later study and subscribed!

Very good video my man !! Easy to understand and to the point !

[danwilliams]

Great video and very helpful!
I have a question….
It’s about the Lunchbox in the background 😆
What chassis is it on?
Many thanks 👍

I actually stopped messing with my RC car because I made it TOO fast. It was fun building it and modifying it but i think i crossed a line somewhere. Its way too fast and accelerates WAY too fast to the point it almost rips itself apart. I stopped when the next logical step was to upgrade all the parts to support the speed/torque. I live in a densely populated area so fast became not so much fun after a while.

Long story short i watched your video so I could learn more about how to gear it back down again because i previously just used trial and error to get it high torque and speed (upgraded so much stuff).

Thanks for this video it real helped me understand how gear ratio works better!

When we talk about brushed gear ratio has to be taken in good account since it is very important to get in that suggested range, considering how unefficient brushed motor are. Brushless on the other hand is more elastic

Do you happen to know what pitch most 1/8 scale buggies and SCT use, neither one of my manuals say they just tell how many teeth, I converted my 1/8 scale buggy from nitro to electric and the motor came with a 15tooth pinion and my center differential gear is a 46 tooth and it's real slow but the motor is barely getting warmer than ambient temperature, it's got incredible bottom end speed but top's out about 25 mph, was thinking of trying a 19t or 20t, your opinion would be greatly appreciated and I know that the 32 pitch gears don't mesh with the differential gear

Friend, please help me, I'm new to car modeling, I built an onroad car, with a 64pitch pinion with 40T, and a 64pitch 96T spur gear, I use a hobywing 10bl120a esc, the futaba 3pv radio has the end point at 100%, the 10.5T Brushless engine for 1/10 cars in the few laps I drove, the spur gear damaged all the teeth, how can I be doing so that this doesn't happen?

Nice simple explanation for the beginner, good work. B'N'CD

hello, im converting a 1/10 scale nitro basher into a brushless basher. my stock gearing (2speed) nitro gears are 45t and 50t spur. I want to add a pinnion onto the brushless motor that will work well with the 50T spur thats allready on the car. im planning on using 3650 Brushless Motor 4500KV 60A. could you help me pick the right pinnion size to go with this setup?

So for carpet racing would you want to have faster acceleration then top speed ?

I have the element enduro senduro. i changed the pitch to 32 on the spur and pinion. i have the slip pads and washers for the spur. Can i run this with the same trans and if so, what other parts do i need. If not, what do i need to buy to make this run because it's not running.

[TheAnthonyBrandi]

I have a arrma Gorgon and I switched from a t15 to a t26 and it's slow. Should I change my gear ratio to gain more speed or switch to a 12t.i keep burning up the stock. Motors.

[Thegreatesthits-su]

When i was young i would use to take my rc car apart and take out the dc motor.

[high-octane-stunts]

Would there be a way to make an rc car be able to “cruise” at a speed without it being almost full throttle the whole time

[FahmiSani-ql]

If the gear ratio is 10:1 whats the spur and pinion gear t?

[sirex]

I understand gear ratio, but why not put big gear on motor and smaller gear for wheels? Or it will be too much and car will be ripped in peaces? I am desiging my own rc car from 0 level and i thought that it was something logical, but i might not understand smth
