I’m shocked more people dont watch this series this build is dope as hell and very informative 👌🏼

[@rcclassiccrawlers4368]

Very cool build. Love the detail you use to explain your process. Keep up the great work.

[@Jim-gi6ov]

Awesome looking buggy..great job & thanks for the ideas on stuff. Excellent clear instruction. Thankyou..

[@PetalosFam]

Man, o love all the info. Thank you. Kart is dope!

[@bigpermsgarage6290]

I'm glad I found your channel from rather b welding! Thank you for being so thorough. Very cool build.

[@teamletteracing]

Your videos are awesome! Appreciate the time you put into them

[@mihkus]

You have seriously good content. First time ever I see someone build a front suspension and steering exactly how I would do it if I had ideal conditions with infinite amout of time. That 1.5k subscribers will be 200k by the end of the year if you continue like that. Great stuff.

[@timstewart567]

Thanks for the great information and education. I have been building mostly two-wheeled projects but am collecting parts for a crosskart build. I'd like to get my steering geometry right (or close to right) on my first try. This should help!!!

[@MGSnake100]

Damn this was informative! I'm looking to build a street legal version of a buggy like this so minus a few street legal details this showed me a lot of what I need to know. Thank you!

[@josecuadrado6699]

Dude your video is the shit thank you so much for the series much love

[@Thewatson77]

Man you’re really putting out some great information with this video. Much appreciated for sharing all the research and work you’ve put into this bad boy so far 👍🏼👍🏼

[@jimkhana6881]

Thanks man that was the idea! I want other people starting from scratch to learn as much as possible! Im not a fan of the pro guys that wanna keep all the secrets lol

[@Thewatson77]

@@jimkhana6881 I couldn’t agree with you more about not keeping all the secrets. I’m all about sharing knowledge and helping others with their projects as well , I think that’s why I can truly appreciate the time and energy that you’re putting into it. Like minded people should be helping boost each other up so we can all learn and grown our creative passions together. 👍🏼

Nice work!! You would like to see my homemade 1/5 49cc RC car!!!

[@brianswelding]

Great job!!!

[@jimkhana6881]

Thanks brotha

[@sepedius]

Its also great for going over bumps when your a-arms lean back just a little bit like yours. It puts less stress on the joints! Never thought about that?

[@davidcart28]

Hello and thank you for documenting these videos. I love to watch build vids it gives me inspiration to do something but here in the uk we do not have many places to use them so almost makes it pointless. If you like fabrication look on here for project binky you would love it Keep up with good work stay safe

[@steveharmon9000]

What cad program did you mention? Something 360 ? Why did you choose that one? Great video btw.

[@prahlad7412]

How did you attach the rod end joints to the chassis like that? did you weld on threads?

[@naiquetonge4315]

Waiting for the build plans

[@CamberKitesurfing]

that's gonna be super cool, have you done a video on how to get good ackerman angle?

[@jimkhana6881]

Ive talked about it briefly in the steering video. I havent figured the math though

[@felmi5032]

Thank you for your videos. I started researching for crosskart builts months ago but your work will help me a lot when i start my own crosskart. Probably you already know it but these 2 channels build almost the same crosskarts. Don't want to advertise their channels but maybe you still need some ideas for your project : Kj Raycing and Murisec54

[@jordanbuchanan6511]

Hello, Awesome content I love your build series Does your steering setup have an adjustment point for toe in or out for alignment?

[@jimkhana6881]

Yeah the adjustable heim joints in the tie rod will adjust toe

[@toekneecovarrubias6185]

Antidive is for heavy breaking so you won't lose your caster angle causing ur wheels to toe out

[@JonathanNichollsjono]

Your kingpin inclination is fine as it is. You don't want camber change when suspension is compressed while the crosskart is traveling straight. You only want camber change when the front wheel suspension is compressed or extended in a turn. You do that by increasing caster angle. At the moment it's about 5 degrees (ok), 8 degrees to 10 degrees would be more ideal. However, check it yourself by turning your front wheels to see how much positive or negative camber it has in each direction. The wheel that you used in the video should have positive camber to the right (becomes inside wheel in a turn) and negative camber to the left (becomes outside wheel). Castor does mainly two things, it helps with stability so that your steering centres itself, and it introduces camber change in turns. Too much camber makes steering heavy.

[@SikSwanger]

I agree, all though you really won’t know the exact castor that car needs till you start text driving it. This is why I made my top a-arm adjustable to change my castor without pulling the top a-arm off the car. It might look all good when you turn it left to right and cycle the arms up and down when it’s sitting there, once you put the car through load that’s when you will really know where the castor should be at in my opinion. 👍

[@JonathanNichollsjono]

@@SikSwanger correct and I agree with you. I was just giving recommended castor angles for reference. Note: I looked at the thumbnail of the that turned wheel, in my personal opinion, I would increase castor slightly to give the inside and outside front tyre 'bite' in a turn when you are off road.

[@SikSwanger]

@@JonathanNichollsjono all good 👍 I wasn’t trying to correct you bud, Just putting my 2 cents in and what I’ve learnt and experienced over the years with these machines.

[@JonathanNichollsjono]

@@SikSwanger I'm not offended at all. Always good to discuss these things.

[@jimkhana6881]

Thanks guys. its something im gonna have to play with. I read a full suspension write up from a reputable crosskart builder (from 12 yrs ago) and they were shooting for 0-4° caster. didnt understand why and it sounded crazy low. Eapecially when you look at the other crosskart companies at full lock and their wheel ia cambered in (what looks like) 8°! But like @sikswanger said, i wont know til i run it. I GREATLY appreciate your guys' feedback. it means a lot to me. keep it coming theough the build

[@stevenpleasant5834]

Hi good video info could you show how you adjust the Caster please and very cool build do you think maybe some day you might try a 4x4 buggy build well keep safe.

[@jimkhana6881]

as of now I would make very slight adjustments by adjusting the front upper heim out and the rear lower heim out. Theres only so much adjustment in there though before everything else gets screwey

[@brianholt2058]

Thank you just that thank you. . .

Amazon sells some shocks that have 10in of travel and support 500 ibs 50$ each!! I’m currently useing em on my rear of my buggy, it’s definitely cheap I’ll say that, great vids keep the great work up!!

[@jimkhana6881]

Yeah There certainly are cheaper options. Ill be moving to a cantilever setep so i can run smaller, cheaper shocka

[@jasonbirch1182]

@@jimkhana6881 it's push rod or rocker arm, not cantilever. Everyone who says that is wrong. A cantilever is a stationary support structure not a moving system. Ever heard a overhead valve pushrod engine refered to as a cantilever engine? No.

[@BubbaB43]

@@jasonbirch1182 damn came in a little aggressive with that one huh! Either way I can tell you that the man definitely knows his shit just by looking at his buggy, so until you start making videos with this kind of quality content I'll continue to listen to him! Got to love all keyboard mechanics as they always seem to have the expert answer!

[@antoniskaloterakis7996]

Hello , Great video , great car cant wait to see it finished . I would like to ask you a question I ve heard you said that the maximum kingpin inclination shouldnt be more that 12.5 degrees , what if it will be ? what problems should that have , I am designing a leaning tricycle than in order to have zero scrub radius has to have 22.7 degrees kingpin inclination , I havent finalized yet the design and i might finally make less inclined or maybe not inclined at all , but I dont know things get way too complicated with leaning , whats your opinion ?

[@jimkhana6881]

I think you want some scrub to keep the bike tracking straight. The trike is totally different. I'm strictly talking about a crosskart with this ride height and geometry

[@antoniskaloterakis7996]

@@jimkhana6881 i dont know what you mean by bike traking but ok , I know its diferrent but the bump steer is the closest thing to lean steer , if the tie rods wont be put in the correct position the wheels will steer as they lean . In the current 22.7 kp setup i have now i see that the point that attaches to the rod end changes height for example 40 mm when steering right and 20 when steering left so i think that would effect ackerman making it more complicated
