For every mating pair of gears in an RC car, there exists a gear ratio. The gear ratio is simply the number of teeth of one gear divided by the number of teeth of a mating gear.
What gear ratio is best for RC drag racing?
The Drag Slash’s standard 76/22 gearing is perfect for all-around driving fun.
How is differential gear ratio calculated?
The calculation uses the number of teeth in the ring gear and divides it by the number of teeth in the pinion gear to provide you with a [result] to 1 ratio. For example, if the pinion gear has 41 teeth, and the ring gear has 11 teeth, the ratio would be calculated as 41/11, which is equal to 3.73 = 3.73:1.
What is a 5 to 1 gear ratio?
For example, if a motor drives a 12T gear to a driven 60T gear on an arm, the 12T driving gear has to rotate 5 times to rotate the 60T driven gear once. This is known as a 5:1 ratio. The torque output is 5 times as much, however, the speed output is only 1/5.
How do you calculate 3 gear ratios?
To calculate the gear ratio:
Divide the number of driven gear teeth by the number of drive gear teeth. In our example, it’s 28/21 or 4 : 3. This gear ratio shows that the smaller driver gear must turn 1,3 times to get the larger driven gear to make one complete turn.
What is the best gear ratio for 1/4 mile?
A 4.10 gear would be your best bet to get because it will push the weight out of the hole and it would be easier to adjust your MPH with tire size.
How many teeth do 3.55 gears have?

How do you calculate rear end gear ratio?
Turn the wheel TWO revolutions and count the number of driveshaft turns. The number of driveshaft rotations will help you determine your rear axle ratio. For example, if it turned 3 and a half times, it’s a 3.50:1 ratio. If it turned 4 and a quarter times, it’s a 4.25:1 ratio.
How do you calculate final gear ratio?
By simply dividing the ring gear tooth count by the pinion gear tooth count, the ratio is determined. For example, if we divide a ring gear with 41 teeth by a pinion gear with 10 teeth we find that the gear ratio is 4.10:1 (41/10 = 4.10). Tire diameter will also have an effect on a vehicle’s final drive ratio.
Do gear ratios add or multiply?
For example, for the gear at left the blue gears are 7 and 21 teeth, while the green gears are 9 and 30 teeth. Thus, the first gear ratio is 7:21 and the second is 9:30. Multiplying the two together gives (7×9):(21×30) = 63 : 630, which is 1:10.
Which gear ratio is faster?
A lower (taller) gear ratio provides a higher top speed, and a higher (shorter) gear ratio provides faster acceleration. . Besides the gears in the transmission, there is also a gear in the rear differential. This is known as the final drive, differential gear, Crown Wheel Pinion (CWP) or ring and pinion.
What is a 8.1 1 gear ratio good for?
Baitcaster gear ratio chart
| Gear ratio | Speed category | Main applications |
|---|---|---|
| 6.7:1 to 7.9:1 | Medium speed | Standard applications (e.g. spinner baits, swimbaits, plastic worms, bottom bouncing rigs, etc.) |
| 8.1:1 to 9.3:1 | High speed | Open water fishing, long casting, pitching/flipping, targeting bass close to cover |
How do you calculate gearing?
How to Calculate the Net Gearing Ratio. Net gearing can also be calculated by dividing the total debt by the total shareholders’ equity. The ratio, expressed as a percentage, reflects the amount of existing equity that would be required to pay off all outstanding debts.
How do you calculate work?
Work can be calculated with the equation: Work = Force ? Distance. The SI unit for work is the joule (J), or Newton meter (N m). One joule equals the amount of work that is done when 1 N of force moves an object over a distance of 1 m.
What is the fastest RC drag car?
XO-1
Traxxas claims its all-wheel-drive XO-1 is the world’s fastest ready-to-run, electric RC supercar. It says the XO-1 can hit 60 mph in 2.3 seconds and exceed 100 mph.
How fast is Traxxas drag slash?
In the end, we were able to achieve a top speed of 65 MPH. Like with other VXL vehicles, the Drag Slash is equipped with TSM or Traxxas Stability Management. We found it best to turn down the TSM for straight-line, high-speed runs.
How fast do rc drag cars go?
The majority of RC Dragsters can typically hit up to 60 to 70 mph, but there are some that can hit up to a whopping 100 mph.
Does higher gear ratio mean faster?
Gear ratios can be boiled down to a single statement: Higher ratios (with a lower numerical value) give better torque/acceleration and lower ratios allow for higher top speeds and better fuel economy. Higher ratios mean the engine has to run faster to achieve a given speed.
What is the best gear ratio for a semi truck?
1 to 1 or direct gear, is always the best gear for fuel mileage, quietness, cooler temperatures in the transmission, and more pulling power. However, to run in direct gear, the rear gears must be either 2.64, 2.47, 2.21 and I think there is even a higher gear than the 2.21. The average speed today is 70 miles per hour.
What gear ratio is better for torque?
In general, a lower final drive ratio will lead to less torque at the wheels but a higher top speed. Meanwhile, a higher ratio will result in the opposite, i.e. more torque at the wheels but a lower top speed.
What does 48 pitch gear mean?
Well 48p is the pitch of the teeth and 90t is the number of teeth on the gear.so its a 48° pitch gear with 90 teeth. its always important to make sure the spur gear and pinion gear are the same pitch.The pitch of each gear must be the same as the other in order for them to mesh properly.
