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 🤘🤓

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. 👍🏼

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

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...

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?

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.

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.

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.
@HarleyDesignsInc

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.

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.
