Best Gearing For Losi 22S no Prep Drag Car! TESTED!

- Taking a box-stock Losi 22S No Prep Drag Car - what gearing works the best for the car?
I bought a whole slew of pinions (from stock all the way up through 39T!), plus a smaller spur gear just to see what would happen.
As I stepped up in gearing, the performance changed for sure...but it is possible to go too far on the stock electronics. Overheating and cogging quickly become a factor. To improve this, new electronics would certainly be required.
Test pinions:
- group 1: amzn.to/3ijIB3F
- group 2: amzn.to/3ihvekw
Losi 76T spur gear: amzn.to/3hL92zU
Have you been testing gearing on your Losi 22S? Where have you ended up at, and at what speeds?

Thanks for taking the time and sharing this info 👍🏻🍻
I hope it was helpful!
That was a good tutorial on gearing a drag car. It really took off a couple of times but I understand the heat issue..it's been hot here in TN. I've been getting a lot of thermal shutdown on my trucks..fans have been a must. Great video 👍
Thank you!
Very cool knowledge , thanks for sharing your results ! It will save others a lot of time ! Thanks for the video !
Thanks for the kind words. I really hope it is useful for others.
cool information and testing
Thank you!
Thanks for sharing👍
Glad to help!
At my local track with Porta Tree timing system, regeared 22S Drag cars with legal (2S) batteries typically run low 2.7's, high 2.6's around 48 mph.
Chasing gearing with the GNSS is difficult because of their accuracy. It's also been my experience that to find the absolute best gearing for a particular car/motor, you need to let the motor completely cool and use a fresh off the charger batter each time. Otherwise, you're gonna find on subsequent passes that it losses a tenth or more after the initial run with the "perfect" gearing.
Thanks for the tips!
I did fully charge the battery between runs, and gave the motor/esc around 5-10min to cool. Still not completely cool by any chance - especially with how hot it was.
Folks seem to continue to talk about these mid-2 second runs with this car, and for some reason I can't seem to get anywhere near it.
I learn this from others youtubers, the higher the gear ratio you force the motor and esc to heat more faster, put more stress and heat, to prevent that you need a much better esc can handle the tires size and gear ratio
Thanks!
Depending on the transmitter, u can set a "soft start" aka "accel". Get rid of the whiplash effect in take off.
Yes! The factory controller does not have this.
Dude
Back off on the clutch
Monitory our your 6 ft time until it’s Perfect. +-.05 constant ,then let see the 132 ft time
The car has to go absolutely straight for 132 ft to get a consistent GPS read
Thanks for the tips!
Nice video my friend 😍😍👍👍👍
Thanks!
I was running 21/84 everything stock except the rear shocks and was using the mamba x esc and just spectrum 5000 mah 100c batteries. And 53mph at low 2.6’s at a local cash day’s using the traxxas tree timing system.
Great - thanks for the feedback!
Pretty cool man..some good options in there don’t think it would be the battery
Maybe! It might just be the ESC overloading also.
Not sure what to think.
Thanks for chatting last night on the live stream!
Just came across this video, and you just mentioned one of your thoughts on being geared too high. I had the same experience with the esc cutting out before the finish line with 23/84 gearing, and I was using a brand new freshly, fully charged 8000mah 100c continuous (with 200c burst) battery. First 3 passes cut out before 132ft. I know it wasn’t too hot. The week before I used a 21/84, with a 5200mah 50c continuous (100c burst) battery, and I was able to get complete runs, without the esc cutting out before 132ft. I thought I would bump up to 23/84, with the more powerful battery, the next weekend, but the esc couldn’t handle it. I programmed the esc to give me the 5th level of punch (the highest), and the 8th level of timing, (the highest), and then I re calibrated the throttle, neutral, brake, (I guess they call that calibrating the transmitter/esc). I changed the pinion back down to 13/84, and tried it out on just a storage charge, (3.8 volt per cell). It did not cut out, battery was not fully charged, but got 2.84 46mph. Tomorrow the battery will be charged all the way. Tires will be sauced, wish me luck. But yeah, I think that stock esc, and motor, cannot handle that much torque, or too tall of gearing, for sure.
I agree 100% - I think the stock ESC just can't handle that much load.
Good luck with your testing! I hope you find a few more tenths to knock off! :)
@@RoadsideRC yes sir, as always, I love the testing, and videos you do, and now, some of the comments that people post. Thanks for all the great info, from you, and your viewers.
this cleared up alot for me i was having the same problem thank you
So your results are specific to your motor, correct? If I have a 4.5T motor, which the manufacturer suggest a gearing ratio of 7.5:1 to 8.2:1, what size pinion should I be using?
Yes - my results are for my motor/esc - total setup. There is no "right" pinion. You will need to get a set of pinions like I did, and test it for your specific situation.
good sharing.
Thank you!
Hey I’m a new subscriber to the channel , your content is awesome, I just bought the Losi 22s roller kit , thats how I stumbled onto your videos looking up what I can do to make this thing better , my question is , do you think I should go with the electronics that the car comes stock with ? Or should I go with something different, I wish I was able to get the rtr but my funds at the time weren’t great lol
Actually, you did the right thing by getting the roller.
The RTR is not setup for any class. Doesn't fit in 13.5, and too slow for Outlaw.
You need to see what classes are run near you, and pick one to go with. That will dictate what electronics you go with.
@@RoadsideRC thank you so much , I’m very new to the hobby , like a month old new , I started out with the kyosho Fazer Mk2 (El Camino) I put a copperhead 10 1406-5700kv combo and love it , but drag cars are more my style and doing research the Losi roller kit was more appealing to me . But thank you for the advice and can’t wait for your next video!
Best videos. For example team associated dr10 thanks 😊 about gears have a great time.
Glad you liked it
i found on stock electronics that 84/21 worked best for me ET was 2.54 at 56mph, Punch level 5 and Esc timing on Level 8. Good video! Anything over 21T pinion causes it to Cog off the line...
I saw that myself!
Interesting how drastically faster yours is than mine!
Amazing what I find when I actually read the comments. I happen to subscribe to both of your channels. I should have read your comments first, coach d, before just writing roadside rc, pretty much what you just said. Lol….I agree it does cog, but not so much with a freshly charged battery. But I think roadside rc experienced the same “ esc cutting out”, as I did, being geared too high. My stuff was definitely not too hot, it happened to me on my first 3 runs, at 6:00am, and I check the temps on everything.
84/21 2.54 at 56mph is a great time, might get to put that on tomorrow. That is about the fastest time the losi rtr class winner got, at that straight line showdown, I watch that took place at Great Lakes raceway, or something like that, it was on live rc (you tube),last weekend. Thanks man
@@OH-Hobbies all good fam 💯
How many turns on the slipper an what tires?
Just replaced differential had spur gear out, looking for tips on adjustment for the spur gear with the spring, i noticed on launches it’s less aggressive which is good for now then ramps in down track, want to dial in this adjustment if possible
That is adjusting the slipper clutch. Slowly change it 1/4 turn at a time. Tighter means more power transfered.
Have fun testing!
I thought it would be alot faster than a geared up DR10 stock, but its wasnt really. It all comes down to tuning it seems with these RTR drag cars, which is true for all cars really, it was faster, bit not all that much quicker, sometimes not quicker at all. Good test!
Thanks! Yes - tuning is very important!
@@RoadsideRC heck yeah. Love your channel!
Love your site for info just got my first R/C Losi Summit Chevy SS going to run 3s battery in it, i am old school just turned 64 can you tell me what gears i need to have a 3:73 gear ratio. Thanks for any help you can give me Gil.. Ill check back later and let you know how it went.. Thanks Again
Awesome! Hope you enjoy it!!
Your Chevelle is beautiful 🎉
Thank you!
Nice video!! I’m getting 2.710 @52 mph with a 19t pinion gonna try some other ones soon
Great time! Is that with stock tires?
@@RoadsideRC thanks, I’m running proline reactions and gonna try air tires soon
That is the exact same gearing I am trying tomorrow morning. I am using reactions, on split six beadlocks, no foams, tires cleaned and conditioned, (sticky kicks), and I just programmed the esc to #5 setting on punch, and #8 on timing. Tried this set up in front of my house, but battery was only on a storage charge (3.8volts per cell) and I got 2.84 46mph. I suspect I’ll get the same as yours an a full charge, if your esc settings where the same.
@@OH-Hobbies I’m getting faster I got 2.6 @53mph on the same set up
DR rc’s, just got 2.71 50mph, with the same gearing, 19/84, first run on a fresh battery, of coarse. I had to replace the stock spur gear, and slipper pads with a new one, and I also lightly sanded (220grit) the sheen off the metal plates that sandwich the slipper pads.
Out the box no mods I got 2.89 @ 49mph. 5000mah 100c. I don't know if maybe the gnss is wrong.
Thanks for the feedback!
im new to this hobby. ive had my car for a week. stock slipper piled and have an 84 on order. was able to put an 87 tooth in the car with the stock 16t pinion. the car launces way better and seems way faster. but seems to go against all the information ive been reading. everyone says go up bigger on the pinion. would anyone be able to offer me some insight
Getting a performance analyzer - like the GNSS unit is KEY for drag racing.
The spur gear swap was only 3 teeth = 3% total change (3/87). It would be an unnoticeable change.
As an example, a single tooth on the pinion would be a (1/16) 6% change in gearing.
cool 😎
Thank you!
Are these runs on 2S or 3s lipo ??
2S
I've heard the 22s is illegal in some drag classes. Is that true?
Hmm. Good question - not that I have heard near me.
@@RoadsideRC ok. Maybe it's just a sort of club to club kind of thing.
I was running better that that on stock.. r u doing burnouts? I don’t understand..and I was only using a 75c battery… 2.910 at 47 mph.. not I put a 21 in and I haven’t tried it yet.. also removed my cover cause of the axel.. if u can get it dialed in so it’s running straight instead of doing a lot of steering input that would help.. I also use a floor mat out of my car to do a burn out on.. I will try and run it this weekend and let u know how it does..
Thanks for the feedback.
Yes, for some reason, this car seems slower than basically everyone online. Not really sure why, honestly.
3s?
Nope. Only 2S allowed in my local area.
So realistically nothing made a huge difference
Of course it only takes a little bit to win a race
It was more the limitation of my battery and electronics.
@@RoadsideRC right. That is the name of the game in competitions. That’s what makes it a semi level playing field. That is kind of why I’m interested in this car. I have all the 80-90mph 6S-8S off road stuff. But you have to get creative to get insane speed on 2S
