Does overdrive in RC Crawlers actually work? - pros and cons of overdrive gearing for rock crawling

[@RCReviewChannel]

Big subject for sure since overdrive is so popular these days. Most folks do a bunch of mods though when installing overdrive so it's hard to evaluate the effect of just overdrive. It's key to isolate just overdrive's effect so folks can make an informed decision about it. Agree or disagree with the effects of overdrive? How do you know its effects and what situations does it help and what situations does it harm performance?

[@deliriousruis4170]

33% is too much od. 22% is optimal. Helps you steer way tighter and back wheels still help you climp steep hills without back flip. Building comp trucks helps finding the optimal setups. U dont need od at all when u just go safaring.

[@Harvey600]

Though I don’t have much crawling experience, listening to what you found in the test, I engineer brain thinks that 33% od would give an advantage in something like a cheater rig, but, on a trail truck, it’s not worth the expense. I’m building an Elements builders kit 2, I’ve gone 5% to begin with, I haven’t had a rig with od on it before, so I want to see what a small amount gives me, rather than going 12% straight away. Thanks for the test and results.

[@Egsise]

Finally someone who can do side by side tests. I have kept my crawlers stock and their performance just keeps getting better and better. Or maybe my skills just improve the more I drive, silly idea isn't it?!

[@joshrichie9833]

33% is to much i wouldn't go more than 15% and it helps going down when things get weird the front pulls the truck out of a tip over or forward flip over better

[@twisterzman]

Interesting, due to so many who claim it's such an advantage. My trail trucks obviously don't need/ want it, my "closer to comp " class 2 truck seems to not need it as well, but...I found shock and obvious tire choice makes a bigger difference. Thanks for the comparison.. You proved that driver technique is the best "mod" you can make to your truck. 😉

[@Roadnuts86]

I’ve only run overdrive in my two Element trucks. My Sendero runs the optional 12% and my Trailrunner runs 6%. I find, on most of the obstacles I tackle, that overdrive helps me noticeably. I’m glad I have it and have no intentions of going back. I really notice it when climbing and having a sharp turn at the top, it really pulls me up and over. Also, when sidehilling, I’ve found it helps pull the truck to safety in my experience. Overall, I think some overdrive is good, but maybe too much is a detriment?

[@RCReviewChannel]

Pull the truck to safety. I like that. Having a little slide in the rear helps pivot the truck up towards the hill.

[@mgscheue]

Yay, physics! Well-done.

[@shushstunes]

Hi I have a element rc enduro and have seen several KZbin videos where people have laid their rear shock down in a diagonal position for more rear suspension travel. I would love to see you test different suspension configurations to see what improvements can be obtained for better crawling Thanks

[@ryurc3033]

Just one thing I've learned from my own shock testing, sometimes giving up a touch of flex for stability is better than all out max articulation.

[@FredrikOlesen]

Agree, you Can make to much flex And droop☺️

[@EXPIOWA]

I agree with your assessment. But will take it even farther. OD is generally worthless. It creates a partial bind situation. With experience you realize keeping your rig bind free is more beneficial. Knowing how to manage binding situations is high level crawling. If you don't know what I am talking about you will later when you level up. 😉 Don't worry about it. OD causes continuous strain on components and run hotter. Shorter battery life is another fun side effect. If you are at the rocks with me and start bragging about your overdrive, I will say, "Cool". Then proceed to drive around you.

[@RCReviewChannel]

Thank you for sharing your insight and experience with us.

[@loum7008]

Thanks for the test!!! Maybe 33% is just too much. I have over/under 27% in my TRX4 Sport and really do love it. You have a bunch of hours on your TRX4 sport. I bet if you swapped out the overdrive you'd miss it. Hey thanks again for all your content. Greatly appreciated!!!

[@sr20detized]

The lighter the rig, and the more front biased the weight of the rig, the more OD will be a benefit. I don't see the benefit beyond 10% or so in trail, light crawling rigs. You'll definitely notice the benefits in comp oriented rigs. In a heavier rig you're basically adding "in motion" dig. You would never administer dig in a climb but with a heavier rig that is exactly what you're doing with all that weight transfer when it gets steep. Just a little OD to keep those front tires dug in is what you want in a trail rig. Great demo.

[@jasond1245]

I've never thought od was worth it reason I don't have it in any of my trucks.

[@EverydayMinimalist]

Overdrive on the vs410 is great for a “2nd” gear. However the rear axles have to be locked into neutral. That’s about it lol

[@RCReviewChannel]

Great advice. A lil more speed!

[@gamingstokr7299]

Great video here. Really shed some light on something I've heard so many praise. Definitely a pass for me now. Not enough situations where it provides a clear advantage over the number of situations where it actually hurts.

[@RCReviewChannel]

Exactly. Everyone recommends it but few actually where it helps and where it harms performance.

[@danweiss4928]

This is why testing is so important. I am a firm believer of testing before I claim something helps!!

[@RCReviewChannel]

Yeah having a switchable overdrive really allowed the A/B testing on same conditions/time

[@richardemmons835]

It's really about getting weight added if you add overdrive if you get more weight forward or add forward weight the beautiful thing happens when the two are added together 🤙

[@RCReviewChannel]

Yeah, overdrive has a better chance of contributing if the vehicle is already optimized for low, forward weight. And good traction is needed too. Overdrive may help throttle bump techniques too.

[@crocsonletsgo9665]

Spoiler alert. Not really. 😂

[@Memeteam903]

So I guess I need to tell all my friends how awesome I think there overdrive is and wish I had it while I continue to make climbs they can’t and call it skill🤣

[@RCCinematic]

They be overdriving these prices on RCs now.

[@ChrisGorman87]

I just can’t get myself behind this whole overdrive front gears. As a mechanic I wouldn’t do it to my real truck so I wouldn’t do it to my crawler. But that’s just my opinion. Take it like a grain of salt lol

[@bluecollarbarbell4370]

Good information, I makes me rethink overdrive. Thanks

[@paint444]

I have an moa crawler so can dial in any overdrive I like. Crawling at its non overdrive limit..when I try the exact same with overdrive....absolutely no chance. Taction is everything crawling...so surely overdrive has to make one axle skid..whether climbing side hilling or descending...you need Traction!

[@rcbashnz3096]

I run in the forest, so dirt and tree roots, I have found the phoenix overdrive very situational, the 6% is good all round, but a few places the 33 can drag it over the top where the 6 can't, just about finding what it can and can't do, trial and error, part of the fun

[@RCReviewChannel]

True. Great to have the switching options. The key though is explaining where it helps, where it doesn't and where it harms performance.

[@cburns117]

Well, I just got my underdrive gear for my rear diff on my TRX4 Sport yesterday. I was watching this for some positive affirmation, but here comes Francis with the honesty bomb! Great video

[@swerv512]

I'm looking at a few transmission options options right now for a trx4 portal- based LCG rig. Now I'm really scratching my head... or is it now clear which style of transmission to buy?!. This video shattered all of my very limited crawling knowledge. I guess I need to do the research myself. Thank you for continuing your unbiased reviews and research to help us all get a better idea of what and when things work.

[@gibsonlife573]

I think a lot of guys run overdrive to be able to turn sharper and then and also helps suck your front wheels down sometimes you know or lay your tire over on its side and use the sidewall or there's certain strategies in overdrive really help but I can definitely see by this that it is not that great

[@joenames670]

I think it all depends on the type of rocks, here in Vegas our Red rocks have this sand paper texture and over drive shows improvements in climbing. Was testing it out with my vs410 phoenix as well.

[@RCReviewChannel]

Correct. In high traction situations, overdrive has a chance to help in the steep ledges.

[@manualuserX]

My trucks just need brass 😌

[@gpaull2]

We don’t have grippy sandstone where I live. We have loose dirt, roots, moss, etc. My friends without overdrive clearly have more traction and easily get up hills that struggle on with my VRD Carbon with 33% overdrive. It’s like applying the rear brakes.

[@RomekRolnik]

The gears ratio difference is too big, 25% overdrive it is maximum in my opinion for stock model because it’s start to dancing side to side like on a muddy uphill if it’s more than 25%. In my rig I got 20% overdrive and it’s optimal ratio for me, rear axle needn’t to be dragged by a front one like we could see here with more than 30% overdrive. My opinion about overdrive is positive, 1.)it’s help a lot for climbing purpose but if you know how to play with gear ratio. 36% is a way to much for stock car like this 2.) positive thing is stability on rocky climbs. With overdriven front axle, model completely stopped to jumping and losing contact between tires and rocks and that’s the most important thing in overdrive I think. 3.) over 30% of overdrive at the front gonna work as hell but you need also distribute weight of all car like 75% -80% at the front with low gravity center. Than it’s a killer BTW You have one of the best RC channels on KZbin man and for sure best one about RC crawling. You using the same crawling track, same hills and obstacles with bunch of different rigs. That’s help a lot, showing differences between different models. Great comparison, great episode and great job at all. Greetings from Poland 🇵🇱

[@scale6039]

Great review, puts me thinking if I really want overdrive in my crawler. Espacially for were I ride. Thanx 👍

[@RCReviewChannel]

Exactly. That's my intent is to make sure folks understand the dynamics and are able to make the right decision for them, instead of just following the hot trends.

[@gb25jr]

So I am new too this..which one do you choose? 12t- 33t or 10t-35t or 11t-34t? That's where I'm confused...some help would surely be appreciated..

[@mickd8188]

That's the beauty of the the Phoenix and Vfd twin.... you have all the options including dig at the touch of a button to flick through and try while getting the line done... All my other rigs are generally 6% to 11% with dig which is a pretty good balance of performance for a wide range of terrain and driving. Cheers 👍

[@RCReviewChannel]

Thanks for sharing. 12% seems to be a good balance without too much downside.

[@oscarg439]

Can i run overdrive if i run on both trails and flat land constantly? Also will it help in snow?

[@yiarkungfu]

I was just getting ready to overdrive my belly dragger, you saved me some bucks and trouble. Thanks Francis

[@petejones6827]

im wondering if i can put the overdrive gears in the rear also on my trx4m, heres my theory i have the crawler gears i love the slow crawl but it lacks in speed but i also dont want the trail gears cause it lacks in slow crawl i wish i could get a gear ration more in between them since i cant maybe i can just overdrive the front and rear 27% bringing my top speed up but not taking away too much low speed crawling

[@dennistolentino5275]

i idol,, i just want to know the ar44 overdrive is same the k44? this is compatible? thank you

[@mgscheue]

It does make sense. The coefficient of static friction is always greater than the kinetic coefficient and, with overdrive, assuming all the tires are in contact with the surface, some of them are always going to be slipping, so less grip.

[@shuster1921]

Wait,,, What?!,,, ;-)

[@DSMOffRoad]

Well done. I’ve found the same results myself and prefer very little overdrive.

Love this. Any amount of repeated testing will show you that OD can't benefit you if you don't have traction. Why everyone aims for 30% is beyond me.

[@RCReviewChannel]

Exactly, exactly. And now I see how harmful it can be when traction is low or when one doesn't have the best tires.

[@BigO-fg1fn]

Guys would I go overdrive 27t in front and under drive 33t on AR44’s?

[@petejones6827]

so what im getting is it helps in LCG build where you are maxing out your climb angle

[@houstonrccrawlers6445]

Overdrive is better in comp build and rigs that are for pure rock crawling like gspeed build trx4 build and so forth in my opinion

[@RCReviewChannel]

Agree. The rig has to have the best low cg, forward balance for the Overdrive to help. And then for just steep climbs, overdrive is not that helpful as it loses traction. For ledge type technical climbs, it can help. Gotta have that sandpaper like grip though.

[@krisbahler8264]

Awesome review thankyou! Just as Logan from Western Desert Wheelers says, 'keep the rubber side down', that and applying drag racing methodology, it's all about the traction that comes from great geometry

[@RCReviewChannel]

Great tip! Traction is always king. And weight distribution!

[@DTW-bx2vy]

Overdrive / underdrive makes climbing slightly better but it certainly makes the steering radius far worse. Steering radius, proper weight distribution, & tires are the most important factors in a crawler rig & I would never take away steering radius just to be able to climb only a small bit better.

[@RCReviewChannel]

Overdrive/underdrive improves steering radius for sure. The reason is it drags the rear tires a little bit as the front wheels are spinning faster than the rear. This is more true the bigger the speed difference. At the extremeis DIG where the rear wheels don't spin and that steering radius is as tight as can be. For climbing, it sometimes help, but only when there's a lot of traction on hand. Slipping the rear tires is not a great help in already slippery conditions.

[@D.C.Johnson]

This is good information 👏. Potentially could inform the hobby in new ways moving forward. Innovation relies on fundamentals and application provides confirmation.

[@nathanstrong4359]

Just switched back to stock diffs. I’ve seen too many times my rig loses traction. Thinking about it, OD doesn’t really make much sense and I feel I just sort of bought into the gear hype instead of truly running the best stuff for what I want to do.

[@steveblackbird]

Really appreciate your review Francis. I for one was going to overdrive my modded SCX10 but after watching this I think I'll keep it as it is.

Oh and experience with a bit patience goes a long way too lol. Cheers!

[@ka4172]

Would be nice to test how shiftabel lockers can help in difficult situations.With a open rear your truck never roll over on the steepest hills you can turn tighter with a open rear.I have several situations cant get out because the locked axels push the truck straight in to the obstacle.With open the lockers the truck can get out of a ditch where locked axels doesent allowed climb out. Try you will be surprised what possibel. An open axel can also turn one wheel with double the speed because of the differential effect this sometimes help me on extreme slippery surfaces. Try you would be surprised what sometimes possibel.It doesent matter if you cant get out with locked axel why not try with open axels ? It cant get more worse than stuck ,

[@Nordlicht05]

The first thing I did was change the overdrive I to normal gearing.... But I do not use my crawler for real crawling 😂 so nothing to see

[@brianellison3525]

On my sharp rocks with my lcg rig, the od helps for sure. I waited for about 4 months for my gear set to come in, and immediately was able to get the front end to pull itself up and over a crest I hadn't been able to get a start on before. The turn radius benefits alone were worth it. A bit of drag back there, and I'm turning on the inside tire radius very consistently. I think for an extreme crawler it's a must.

[@RCReviewChannel]

Yup, ledge climbs with high traction and tight steering are its contributions

[@BarbarisII]

Say I want 20% more upfront, but I don't want to actually increase the speed. Could I put 20% underdrive in back? What are the comparisons between underdrive/ overdrive, an I on the right track?

[@CasperRc81]

We don’t have those traction issues in Az a lot of our rock is break over edges etc. I can’t stand a vehicle in Az without dramatic OD. my trx4 defender which I lightened back half into a truck and cut about 1” up into the doors easing the sliders about 10mm into the body I drive without. Why? Because with my 55t motor and the Lowest pinion gear 9t maybe I can unlock the rear diff and loose traction. The steering trumps all rc’s radius stock. I have a custom rig that has the og scx10 front axle with the gear overdriven from stock and huge jump in rear with the ar44 rear axle. Think my ratio is 2:52-1 front something like that and the rear ar44 is 3:75-1. My wheel base is 11” that’s why. We have good traction here. Our traction sucks when on river rock type rocks and we use a lot of side wall pressure to pull through lines like V-notches. We should be in the habit of lining up your rear tires for the climb instead of your front like if you were pulling a v notch in the middle of a turn. Your reviews are great happy holidays and God bless you and your family.

[@TerraQuestRC]

I too was having some doubts and maybe it is really only of value in rare situations, which then leaves a question of is it worth the cost. I think the real problem with it is that the front is actually dragging the rear and can cause the front to lose traction faster. I would like to see an option to switch from four wheel to front wheel drive, like dig.. just not locking up the rear. In fact I am waiting for the rest of my parts to build the Phoenix, I am going to give that a try.. not dig but front drive only.

[@jbrc1322]

Cool scientific video. I always had a feeling that high OD was actually hindering certain situations, and it is very apparent now with this platform. However... I must credit OD for making me a better driver due to the disadvantages it poses in certain situations. I believe with the right throttle control and wheel speed, any obstacle can be overcome with high OD vs. low OD. On the other side of the coin, the tighter turning radius can only be achieved with the high OD and that isn't something to write off especially in comp situations where every reverse counts. One last point that didn't get touched on is the way OD essentially acts as a mechanical suck down winch and helps the rig sit lower in most situations whilst in forward motion. This does have the opposite effect when reversing, but with that tighter turning, you shouldn't really need to reverse much, right? In conclusion, for the dedicated trail rig 0%-20% and for the dedicated rock rig 15%-40% works for me.

[@RCReviewChannel]

Good feedback. With a low CG vehicle with great balance and forward weight, I believe one can throttle blip and power punch a little more consistently. Less chance of looping out with a nice brushless bump. I could not demonstrate it consistently in this test video but will keep trying

[@danielkonrad1444]

Thats exactly how it is👍

[@JokerInk-CustomBuilds]

by all logic overdrive shouldn't work... by overdriving one axle you will drag the whells on the other axle and loose traction.... but yes, hanging on the front wheels on a ledge, overdrive will make them spin and dig you foreward and over rather than letting rearwheels push you up before you center f gravity tilts forward... but in all other cases you will prefer traction.... overdrive should ex make your rear end slip on sidehilling...

[@jasonbickford4283]

I've recently done some suspension tuning on my rig. During this tuning I've realized that overdrive really hurt the vertical climb ability. It causes the back tires to lose grip.

1 thing I learned with overdrive from first hand experience is it can and will damage motors.

Not sure on brushless motor but on a brushed motor,it definitely will damage it when pushed hard.

Many of those climbs defiantly slippery looking rocks. But having the front spin 30 percent faster seems like working against each other. Sweet scientific video though.

Low cg, and grip of tires most important in all these scenarios. Unless bell getting hung up! You got best comparison videos out there.

Thanks buddy. We may go to high traction places to further investigate. Throttle bumps/blips may be more effective with overdrive

[@FoyeTroute]

Slight off topic question. Did you use the Burley trailer (test #5) to get the crawler out to your crawl spot? If so, does the crawler bounce around too much back there?

[@motorbreathjz]

how does the overdrive work?? i dont see no mechanical moving parts to actuate them?

[@MThompsonjr115]

Great video! I've always been of the opinion that when you have little to no grip, OD is not as beneficial, and as you found it's worse in some cases. In a high grip situation, it does have some advantages. I think you make a good point, vehicle positioning. I think it is much more important than anything else.

I'm still fairly new to RC crawling so take this with a grain of salt. In my Sendero HD, I went with a bowhouseRC skid + SCX aluminum dig transmission off Amazon. Pretty much immediately, I was appreciating being able to climb and reposition the front tires without losing the rear tire placement. The Sendero has a pretty good turning radius and steering angle, but I found myself not making turns well on a gated comp course and being frustrated by that. I am definitely looking forward to getting to another comp and trying their gates with the dig feature. A couple times I also liked having the dig for controlled decent off a steep rock. I was using the factory 6%, and I didn't notice the loss of the overdrive, only the benefits I gained from the the dig transmission having 4WD / front-wheel drive / dig. All that being said, I still think I'd like to own a VS4-10 Phoenix 😁

I give you a lot of credit for using that nice truck. That is a very nice body on the Phoenix and it already has scratches. Enjoy it!

[@RCReviewChannel]

Thank you. It took a lot of hits since I had to keep driving at the limits.

Great test! Thanks for the effort. I still want the Phoenix for Christmas if i can find one.....

[@RCReviewChannel]

Good luck! We just saw that it's still out of stock.

Hi, I am a beginner to RCs but I am getting hooked to it fast and I like your videos! I was wondering if overdrive could help if you put additional weight on the front...in fact make the truck a bit too much front heavy? That may also increase traction on the front. What do you think about that?
