Josh these are the videos u do I love the most I may not understand it 100% or be doing the same build but it's awesome to learn new things and watch you geek out with the numbers, math and physics of it all that's when you're on your wheel house keep these types of videos coming bro 🤘🤓
This has been bothering me for a while now so I just did the calculations for the StealthX transmission and had to use "percent change" instead of "percent difference" to get the exact advertised over drive values of 11.834% and 5.698% (front gear set 52/28, rear gear sets 53/27 and 54/26) the other confusing thing I found is that the overdrive values are based on just the center and output gear ratios not the final drive ratios.
I dig your technical videos, takes me back to when you first started and would voice details of the details. My mother always tells me “The Devil is in the details.”
Great Marketing Video.. so when does Vanquish start to manufacture the items you just prototyped??? Obviously now that you produced it other people are going to want it also..
Thanks for the math lesson. I myself recently built a "mullet" which I enjoy very much and although I initially guessed what gears to put and where, I'm now able to know exactly what kind of overdrive I'm dealing with and taking the guesswork out of what to install and where, especially since I've been making changes to better suit my personal preferences and driving style. 👍🏼
So your saying my sweet ar44 front trx4 rear idea is probably going to not work based on the axles having different FDRs. Well looks like a VS410 pro is the only option then. Loved the video and the techy info. Reminds me of my 1:1 days👍
I watched the entire video These are the vids i need... anyone can unbox an rtr...... but who's gonna help with all my mad scientist creations if not u..... thanks and keep emm coming
i am a visual type of person, a graphic designer by trade and not an engineer! hehehe you have the truck in front of you... why not show us the insides of this build?
Ya my new bright tj build with a terrible 11.24” wheelbase and 7lb rig I need all the help I can. So I run an overdrive front ax10 metal housing with the hd overdrive gear 2:53-1 and flipping the housing upside down do to the different cut in gears. The rear I choose an ar44 that is 3:75-1 out of my 1.9 wraith making my difference according to your calculator 38.85%. It’s extreme but man it’s so detailed in picking a line. With 4.19 hyrax and 80mm shocks to save pinion angles. I need to loose weight in the rear with such a short wheel base and wanted ground clearance which compared to an OG ax 10 it feels like there is a portal in the rear. Also I made a custom forward trans mount plate milled out of aluminum. And my tcase is another ax10 trans laid down side ways. My forward diff gear drives the tcase slipper clutch shaft giving me crazy gear reduction. I run a castle slate 2850kv micro x 54/11 on 3s and still only achieve 5mph. 😂 your builds are always awesome and has inspired me greatly thx you.
I hate math. But you did a good job of explaining how to calculate over drive 😉👌🏻 Did Vanquish release higher over drive gears or is it only the 6.5% in stock?
I like the video...I did know how to calculate gear ratios....key word did...I petty much completely forgot over the years...now I know again...Great video.
I love these kind of videos! I'm a Computer Science guy, I loved the equations! Really trying to incorporate overdrive more in my kits. Thank you for taking the time to explain in such thorough detail.
The best technical specification about overdrive ! Really clear and full of interesting information about an apparently strange upgrade, that is became significant after your analysis ! Really a good job !
I'm trying to get around 20% overdrive in my scx10ii with ar44 axles. I have the 27t 8t overdrive gears in the front but it's only around 10%. Is there a way to get closer to 20% with out going this route with portals?
awesome video..even when its older . My question is would one of the now easily available budget reverse gearboxes make it possible to put a portal to my budget truck ? A transmission like that is around 40bucks only .
I went with the Ultra, but I have been noticing a lot more Pros, and I was wondering why. I always thought for a crawler Portal axles were the best you could get for crawling. Rear Portal only makes sense to do if that's why you would go with the Pro, unmodified why would the Pro be a preference for a crawler ? Just wondering, already have my Ultra.
It fully a personal opinion between having more clearance at the axle or a lower center of gravity. The Pro also has a little more steering (51 degrees vs 47). And then it comes down to if you like the look of a portal or straight axle better.
Great video...although, I've got another suggestion for you (and, if you do, I'm certain a LOT of people would be interested in a "how to" video): 4-wheel steering VS4-10. Obviously, a duplicate of the included front axle couldn't be used for the rear, due to the offset pumpkin, but maybe the VSP07850?
To build a very capable rig,math is a very important tool to help with the driveline to work at its best performance level.Why bother building a rig to be at its peak performance if you don't understand gear ratios.Its a must know how in my oipion.Thats for sharing.Yes it almost felt like I was back it school for a minute.L.O.L.But still great info.
In your example. If the drive shaft rotates 10 times. The rear wheel makes 1 revolution while the front makes 2. How is this not 100% over driven? 2 is 100% greater than 1.
Because you are assigning the importance to the front or rear without any specific reasoning for that. If do the same calculations but flip the importance, then you get a totally different number. That’s why you have to average. This is just how it’s done, it’s not an opinion, it’s the rules of math.
@@HarleyDesignsInc I am thinking about it as tire roll out. The front tire is covering twice the ground as the rear. I am having a hard time seeing how dividing the difference by the average works. Seems disproportionate to me. If I run the Dready mod on a Hammer T case. I come up with 31.5% OD. What do you come up with using that method of calculation? Not looking to argue. I enjoy math and like to understand it when I come across something new to me.
Makes perfect sense to me but I have been in the offroad 1:1 world for 20 years so ratio calcs are fun to me. I have a Capra and I thought the inside of its 3rd member had an area specifically "carved" out for the ring gear to slide into...now I need to break it down again and see if the ring gear can be flipped to the other side. I would need to swap my transmission out though...Capra trans is geared too high.
im new to asking questions online like this. so please bare with me. i'm debating on purchasing a 410 pro or ultra. my problem is i watched you video on the rear portal install on the pro and that is the way i would like to go if possible. i know this video is old, but has there been any new ways you've discovered to reverse the gears in the rear so i can run portals. i would be a little nervous with all the grinding personally. i would really like to go this route if at all possible. any help would be appreciated. Thanks, Jason
There had been someone who made a 3D printed transfer case adapter to do it as a bolt on option. I don’t have his name though! You could post in the VS4-10 Facebook page to try and have someone post it up.
Alright, I might be stupid here, but wouldn't putting a set of under drive gears in the front help to reduce that percentage as well, interesting build, but like you said not sure if that's something I'd want to tackle, liking the new house studio
That's awesome Josh, I love learning new things !! Appreciate you sharing, I love my VS4-10 Pro. Went together so smooth, while I was watching your live build video, really appreciate that !! Painted mine all-black, turned out awesome !! Just waiting on the LEDs what a great product, always logged vanquish Products. Again appreciate you sharing this video Love learning new stuff about the hobby until the next one
Absolutely freakin awesome vid man! This is the kinda video that keeps me coming back. I'm also a religious SNU watcher and am really only interested in watching YOUR videos on newly released rigs as you take the time to show us the guts... not the revel over the box art. I feel that so many channels are sadly afraid to pursue the math/science at the risk of boring some viewers. Thank you for filling that void and keeping balance in the universe. Now to keep my own balance... time to watch Mr Talbot beat an Xmax like it owes him money! Mmmmm... an evening of math and carnage... a perfect balance. Thank you.
Really interesting stuff! I'm glad you released this video - got very intrigued when I first heard about you building a rear-portal-only rig. After watching your Enduro video with the Vanquish chassis swap, I started thinking about a build myself with the VS410 chassis, Enduro tranny, and SSD axles and was even considering swapping the rear for the SSD portal axle because I heard SBG mention you were running something similar. Then, I heard of the Capra coming out and decided to sit it out and wait to see what it includes. I still have the parts (except the portal axle) sitting around - at some point I'll be assembling them in some sort of combination. I hope you don't mind, Harley, that I included an embed of this video in a new thread over at rccrawler.com to increase discussion of the use of portals, overdrive, reversed transmissions, and flipped ring and pinions for more performance...
Good job, Josh ! I liked the 'chalk board' that you pulled out. I'm impressed that you took on that task. it reminded me of my algebra teacher using gear ratios and torque curves to explain transmission design and shift points. Excellent !
Very outside the box Josh, it was fun to listen too and I was very curious how you were able to get this to work when I 1st came across seeing you run this at that Autism crawl event! Thanks for explaining it in detail.
Nicely done Josh. I would say it was actually refreshing to see a video that is so technical. I thought you did a good job to keep it simple and interesting. I come from the full size world of wheeling, so for me all of this really connects me. Also Josh, i think this is what sets your channel apart from others because you do keep it technical. Im pretty sure the simple non technical people are watching RC Girl. Shes cool too but she is really for the entry level person
I made it Josh, great video its good to know the science, physics and logistics plus the benefits of what we do with our tiny trucks. Keep on bringing it to us. 🤠🇺🇸☝️
This video was perfect timing I'm in the middle of building a custom rig right now and I was trying to figure out the gear ratios thanks a lot Josh for all your help.👍
Don't enjoy math for maths sake, but when it is applicable math I am all over that, thanks for the insight, now I am going to start my own database of gearing stats.
I watched all the way through. I ignored the math because I have no need for it, but if I ever do, now I can re watch this to get the math I need. Good video.
@@HarleyDesignsInc thank you man. I actually watched this vid 2x and copied the formulas from it... and I was braining so hard that I failed to see I was answering my own question using it.
I don’t know if I will ever use this info but it is always cool to see what others are doing . Thanks , the rc hold/shelve looks good. Do you have a video of it? Like to build something to hold my rc’s better.
Harley, I don't agree with your method of calculating the overdrive ratio. You should not use the average. In your example figures of 5:1 and 10:1 your back wheels would be turning once while your front wheels are turning twice. That is a pretty obvious 100% overdrive.
@@HarleyDesignsInc www.rcrcnt.com/articles/calculate.htm has a different take on this. I'm completely uninterested in how much faster than the average my front wheels are spinning, I do want to know how much faster they are spinning than the rear wheels. Why would the average be used? What is the source for your math?
@@HarleyDesignsInc So you are saying that the difference between the average ratios of front and rear is of more importance than the difference between the speed of the front wheels and the speed of the rear wheels? Take that to extreme values and it makes even less sense. Two rotations at the front to one rotation at the rear is pretty easy to work out to be 100% overdrive. I still don't see what value there is to working out the average, it simply adds unnecessary complexity while telling us nothing about the real ratio of front to rear which is what, unarguably, is a far more useful number.
Because that just isn’t how math works. You’re placing importance on one value over another without a reference of importance. As I describe, either number could be chosen and then you end up with two different values. This is just the rule of math, not a debatable method. You can read this for a breakdown to a very simple level if you want more information: www.mathsisfun.com/percentage-difference.html

I watched the whole thing, it was actually very informative, and helpful! So many TH-cam videos just skim across the technical info and it sucks!
Did you just say the VFD transmission is stuck with overdrive? That would not be good for a truck of this caliber... or me...
Did you run the stock links in the rear with the portals? Or did you have to also get new links?

Still more fun than geometry yesterday
I loved geometry! My favorite class I ever took 😁
This look to have fun with. Great info. The F9 portal cost is nothing for Performance.
Could you use an underdrive ring and pinion in the front
Yes. But they weren’t available at the time I made this video.

Math class 101 is fine for me as long as its vehicle related hard data is always great to have but rarely dished out great job
I'm confused, lol. Good explanation on how you achieved the gearing.
Thanks for the video. I was considering this now I can run some numbers see if its doable on my rig
How does it work having an overdrive trans and OD gears at your portals?
I work thru all the math in this video.

Great video, I've always liked math so it wasn't too much in my opinion.
So basically $400 for This rear axle set up
Return on investment with actual measurable performance gains is pretty much zero I'd say.
You lost me when you said "Math" but thumbs up for the math people :)
My head hurts... but... I learned something. Thank you sir.

how did you get the 8.71:1 for the rear
It’s explained around 11:00
Thanks I enjoyed it and now I understand gear ratios much more.
Really cool to do your own engineering. I liked the video. Lot of good gear ratio info.
Definitely a video to add to my stuff I may use. Honestly I watch this channel for the tech.

The shelves in the back are from IKEA and called the Lack. I reinforced them a little but that’s all. Nothing fancy!
Did this to my trx4. Definitely some overdrive in that rig.
Under drive the front as well. This was an interesting video thanks for nerding out on this!
I don’t think they make an underdrive gear set yet, only overdrive which is the opposite of what I need. But maybe it will be available in the future.
Ring gears.would be too big, right??? Or a pinion thatd had to be too small to work right???
Professor Harley. I thought it was fun.
Love the information thank you I’ll put it to use 👍👍
