Wow, I was expecting the calculation to be much more complicated. Thanks for providing the calculator.

Thank you so much for the calculator. Life saver!!

Great info. I found 3 bags with pinions in my spare parts boxes. I know there's some 48p, some mod .6 , but for some of them it isn't obvious to say whether they're P of mod. So I used the calculator and these are the results from 22 pinions : 8 of them were Tamiya 0.6mod and measured as 0.55, 0.56, 0.57 and 0.58mod. None were actually 0.6mod. 2 other pinions were identified as 47,9P - we'll call that 48 . 5 others were identified as 0.52mod or 48,8P - no idea so we'll make that 48P as well (because two of them are known 48P Kyosho pinions) ?... 4 others turned out to be exactly 0.5m but 3 out of 4 are definitely not .5mod (# teeth incompatible with the car) : one of them was new in an unopened bag; a RW Racing 48P 18t pinion ???. I also checked a Novak 32P that turned out to be 32,2P. And a Robinson Racing 1mod that turned out to be .97mod. To top it off, I uninstalled a known .5mod and that came out as .48mod. So I don't know what to think of this calculator. Either the calculator is lacking precision or the brands making the pinions are.

Thanks for putting this info together - exactly what I needed! cheers

Thanks for sharing this with us!

Dude, thanks soooo much. Had to get a replacement gear & wasn't sure how to get the pitch measurement on it. didn't want to get the wrong size. Thumbs up for sure!! :)

Thanks for sharing this info!

Thank You for that 🖤

right on... Thanks dude!

Thanks man 🤘🏻🤘🏻🤘🏻

Perfect, thank you a lot!

Thanks so much and help me alot

Great vid subscribed !

So To be exact, I need to match equally my diametral pitch between the spur and pinion right?

Im struggling, i need to match the amount of teeth and diameter, my value is 9. 4mm and 14teeth for pinion but spur is 16.4mm and 26teeth, so that meants i need a pinion of 14teeth and pitch of 45.4, but it wont mesh correctly ami right?

Nice info Ryan.

Thank you ,

Hi appreciate if you could add the link to your website to the description

Thanks 🙏

Thank you so much mate! This helped me determine what is the pitch of my Xinlehong 9125 pinion and spur. Avoid me to trial and error what pitch pinion do i need for my brushless conversion. 👍👍👍🤜🤛

This helped me out alot thank you.

Pls tell me how to check pressure angel of gear which used for transmission purpose.

good video buddy!!! the question is how can we calculate the pitch cycle diameter of pinion gear??? (I don't know if I'm expressing it right.) i have problem with my rc motor pionion gear.....wears out very quickly I want to change it and I don't know the inner diameter....... I searched for information and the only answer I got from the company is that i must buy new motor and that "they dont know" the inside dimension of pinion gear and they dont sell seperately pinion gear for this motor :-) :-) i dont want buy new motor, its not broken.....just want change the pinion gear of the motor.

Is this calculator glitchy ?? I’ve pulled 3 gears off a basically brand new redcat gearbox, and measured all 3 diameters and counted the teeth.. when I use calculator I get 3 completely different gear pitches. Spur is 79T and 42mm Pinion is 20T and 11mm And the idle gear is 18T and 15mm All three come up different and not one match any common pitch I see ? Please help.. this is from a redcat piranha or cyclone xb10

Are you able to provide the formulas that the website uses to calculate pitch and modulus using the outside diameter and the number of teeth? Thank you for any help.

hello I have a problem with my kyosho outrage. I have upgraded to hobbywing quickrun 1060 esc + cap pack due to esc running into limb mode. My motor is 12T or 14T team orion brushed. i have 15t pinion and 41t spur (both are the stock ones). I have upgraded to 2s lipo and 2.2" tyres front and back. Ambient temp is 36 Celsius. The problem is that despite the cap pack esc is getting into limb mode again and i googled that maybe it is thermal cut off due to overheating. I guess ambient temp plays a role but I wanted to ask if my gearing is right? due to bigger wheels and the motor change.Do they stress my motor and esc?

So this will work, because I'm trying to find a pinion gear to buy and I have a 46t spur so idk what pinion to get?

Very helpful video. Can you please upload a video on how to measure Helical gear for drawing to order new gear. I appreciate your time.

right, so to convert my nitro car to brushless i need a 25.4p pinion with 3.175 shaft size.. i cant find this at all.

Pretty cool website! Dude, I have a doubt about how do I measure the ratio of a worm gear set. Could you help me with that? I can give you the number of teeth of the worm and the spur (worm wheel) together with both outer diameters.

Thank you so fucking much!

Building a hopefully speed car ...thnx.....hobao nitro 7 tq to electric brushless😎

Sad to find out 48p is not the same as 0.6mod 😤

I calculated a pinion and it came up with .68 mod is that still .6 mod orrrr please help

Think KZfaq is messing with you, your video stops after about 70 seconds and then it says no internet connection, then KZfaq tries to get you to download it.
