What is a good gear ratio for RC drag racing?
The Drag Slash’s standard 76/22 gearing is perfect for all-around driving fun.
How does RC gearing work?
The pinion gear is attached to the motor’s output shaft while the spur gear is attached to an output shaft on the transmission. Changing these gears alters the ‘gear ratio’; a higher ratio equals more torque and acceleration but less top speed while a lower ratio equals less torque and a higher top speed.
What is the ratio on remote control cars?
The most common size or scale of an RC is 1:8 scale (or 1/8th scale). Mini-RCs come in even much smaller scales, 1:28 and 1:64 being most typical. Also note that because the scale of an RC is relative to its full-size vehicle, two vehicles of the same scale may be vastly different in size to each other.
How do I choose gear ratio?
The conventional procedure for selecting gear ratios is to pick ratios that run the engine rpm to redline at the end of the medium and longest straights, and pick the lower gear ratios to minimize the rev drop at each shift. This method minimizes the number of shifts per lap.
What does a smaller spur gear do?
Gearing changes are mainly done to make a vehicle faster, or on the scale/crawling side, crawl better. A bigger pinion or smaller spur gear makes the vehicle have more top speed, at a decrease in acceleration.
What does a bigger pinion gear do RC?
As stated previously going to a larger pinion will increase top speed, and generally decrease acceleration. Going to a smaller pinion will lower top speed and increase acceleration. Larger pinion=more heat, smaller pinion=less heat, more heat=less runtime.
What is the difference between 1/10 and 1/16 RC cars?
A 1/10 will have better ground clearance, at least when comparing identical vehicle types, and not a 1/16 size truggy with a 1/10 scale onroad racer. 1/10 is also easier to work on, due to parts being bigger, less cramped together.
Do gear ratios have to match?
As long as there’s less than a 1% difference between the ratios, they’re considered “close enough”. If your front axle only has 4.11 gears (37 ring gear teeth and 9 pinion teeth) but your rear axle has 4.09 gears (45 ring gear teeth and 11 pinion teeth) the ratios don’t match exactly.
How can I make my bright RC faster?
Replace the grease you normally use to a lighter, oil-like lubricant such as WD-40. Thicker grease tends to gunk up, clogging gears and parts, where lighter lubricants will keep things moving fast in your New Bright RC car. Give your New Bright RC car a look over, checking the gears and internal rotating parts.
How do I make my RC gear faster?
One of the cheapest and easiest ways to increase the speed of your RC is by adjusting the gear ratio. There are two gears on your RC, the pinion gear and the spur gear. Both can be upgraded to give your RC either a faster top speed or better acceleration. This is the gear that is attached directly to your motor.
Does smaller pinion give more torque?
RE: Larger pinion vs smaller pinion Smaller pinion = More torque, slower top speed, better acceleration, consequently better runtime, less heat and stress on motor.
Is a smaller pinion gear faster?
A bigger pinion or smaller spur gear makes the vehicle have more top speed, at a decrease in acceleration. It’s most likely that gearing up will make everything run a bit hotter, and shorten run times. A smaller pinion or larger spur gear has the opposite effect.
