Budget Crosskart Reverse Gearbox Install (Harbor Freight Predator Big Block) KJ Raycing VF-1
HTML-код
- Опубликовано: 27 мар 2023
- **** UPDATE!!! The gear box did NOT slow the kart down any!!! Somehow the jet came lose in the carb; terrible timing! Update video coming soon along with a little surprise, KJ Raycing style 🦾
Wanting to add reverse to the Budget Crosskart VF-1 Safari Mode, I found a gearbox on Ebay stating it could handle up to 18hp, it looked beefier than the standard 212cc gearboxes and is sold by reputable company (Blast LED). So I pulled the trigger on a $300 reverse gearbox option and this is how I mounted it. Now figuring out how to mount something is a lot different than seeing how it's done and replicating it; so I hope this helps you guys with your projects and I am definitely loving all the VF-1 builds going on. Having reverse on this crosskart makes me want to hit some trails and it's just in time as the weather gets better here. And I'm prepping all my karts for the Busco Beach trip and can't wait to see you guys there!

Your have made so many peoples dream of building a cross kart a reachable reality with your videos, and I just wanna say, I always get excited when I see you have posted a new video. Thank You for all of your videos, and how open and giving you are with all your knowledge, Your The Best!!!!! Keep Up The Awesome Builds. P.S. you should build one that can jump on motor cross tracks like a Dirt bike, I have only really seen one guy do that, thanks again.
Thank you so much. This was all for you guys so it’s really nice to see a comment like this. As far as the motorcross track; I think some nice custom shocks would do the trick pretty easily on any of my builds… 👍
@@KJRaycinghi i want to know how much its costs for a crosskart and do you export it to other countries ?
@@Centurion. you build it yourself, not buy
I've gotta say the more content of yours I watch the more I appreciate your approach on these builds along with increasing amounts of respect for not only the time you have to put In building em but also the countless hrs you spend just to share the knowledge with us viewers, and btw as much as you appreciate us we appreciate you as well!! I've learned new things and I'm sure everyone else has also id imagine so needless to say thank you for simply just the time you take alone while elaborating on the how to's and all that you share!!! 💯🤟👊
Thank you so much! The channel and plans were all started for you guys at the request of builders that saw my work. It is so great to get a comment like this and keeps me motivated to give you guys more. Thank you again.
Thank you for the update regarding the gearbox and slowing you down. After watching this the first time I've had that same reverse gearbox just sitting in my garage as I didn't want to nerf my death cart.
Great review of the gearbox, probably won't use it for my build...but it looks like it'll be perfect for another project I have!
Although I may never build one of these. I do enjoy watching you overcome the obstacles in the build process. And from one veteran to other thank you for your service. I'm writing this on the 4th of July so Happy Independence Day.
Thank you sir/sergeant. I hope your fourth was amazing. I hope you do get the chance to build one, it is a fun project to tackle.
This is awesome!! Glad to see that you got it worked out!
It’s going to be a perfect trail machine for Busco!
Your one of the few people doing these videos and your videos are probably the best
Thank you sir, I really appreciate that!
Wow, well done mate!
First time subscriber in your channel, once I see your videos, I love crosskarts and builds even though we don't have it here in the Philippines 👍😍
Thank you so much 👍👍👍
The amount of power you've shown there seems just right for keeping a youngster out of serious trouble.
The kids of all ages love it! I have an adjustable throttle stop so the speed can be set wherever, so everyone gets seat time!
Where's the fun in that..? "Trouble" is just another word for "learning" ;-)
Dude thats a sicc crosskart 🎉 makes me wanna scrap mine and go back to the ol' drawing board 😮
Hy, super idea this little box. The rear gear is fantastic. I have one crosscar, with 600 Honda 4 cylinders. It's amazing to drive it. But I have not rear gear, because its an engine of motobike. And sometimes it would save my situation. Thank you for this video. Kris
That's a good job I have seen people using a starter motor it's slow but it works.
I am new to your channel but I like what you are doing, keep it up man.
Thank you so much!
I bought a 15 to blank sprocket took it to the machine shop and had it bored to the same as the 520 sprocket's hub after they turned down the 529 teeth. It had a slight press fit then the two were welded together (one bead of weld on each side). I searched everywhere for a replacement sprocket that would convert it to 420 with no luck. I thought about removing the output shaft and having it turned down to 3/4 with a key way so gear changes would be super easy. I may still do that in the future!
Nice job what a great project
Thanks!
i think the point of the beefy chain is that when you do jumps while on throttle the wheels spin up and when you hit the ground you get massive impact loads through the drive-line.
Love your work mate at least you’ll never have to worry about breaking chains. We race these buggies in Australia and chain breakages with the 1000cc+
Sports bike engines is a big problem( that’s with 530 drag chain too) more power yes. Ps: you need to make that jump into a little tabletop. Thanks again appreciate you work.
Oh I’ve seen the carnage of what you guys race, looks amazing! The “jump” was a start to something bigger but I have massive rocks just under the dirt so it became a test bump 😁. I’m so glad you enjoyed it, we have just as much fun with this under powered machine as we do the high hp karts.
Very cool
Well done.
You are always inspiring people. You always do great work on how to explain your work, but I haven't been able to see/find out how you installed that "TACHOMETER"...
I have a project in process with a forward/reverse gearbox from a snowmobile. I was told they can handle around 100hp.
Nice job ! I agree 100% on that big-phat-chain. On my aluminum 250 Ninja kart , I went from a 520 to a 428. Had to match the 250 counter shaft spline to the 428 pitch. If interested, I can get you the name of the sprocket source (sorry, all my paperwork is out in the shop)
I would like to get that sprocket source, when you have a chance
I put a 459 on my Yurf Dog, with the reverse gearbox. I did it pretty much the same way. Still waiting on exhaust and carburetor breather, had to replace them because of the lack of space.
❤ wow so very nice 👏
stover lock nuts are narrower than nylocks for adding threads to the end of that shaft if necessary
OMG! REVERSE!
Thanks so much for testing that out as I know reverse would be nice but not at the cost of power
We’ll get it back up to where it was. I like to baseline upgrades… if I had done the motor at the same time as the gearbox I wouldn’t know the differences it makes.
I have a few Polaris Xplorer CVT transmission only problem is they're 20 years old now. I'm running 7.25 on the chain side need to bring it down to 5 to 1. She's a crawler non VF build
What tooth sprocket did you use and what top speed what tire diameter what rpm at top speed with 1:2 ratio change in gear box witch doubles engine RPM with gear box installed?
i've seen people use a starter motor on different builds as a reverse option. A bit more fab is needed but the cost is much lower.
Awesome design. Is this the same steel tube as used for roll cage or standard seamless steel tube? Interested in buying plans and building. The difference in pricing between the pipe type like twice as much for the roll cage steel.
Thank you. Honestly in the end you can use whatever tube you want, but I highly recommend DOM (seamless) if you are going to put more than 12hp in it. DOM is the racing standard for a reason, and these can be built for some serious speed. I hope you get the chance to build one 🦾
Go power sports sells a stage 2 kit for a 420cc predator engine I don't know about the 459 max engine.
Found gear box sold not far from me in Ga. Thanks for information.
Be careful that it is not the weak one if you are using a big block motor.
@@KJRaycingit is from Blast LED out of Ga. Found 530 sprocket @ MBI karts out of Ohio with hub drilled for the sprocket hub from Gopowersports
for my alxe.same as the one youused on your cart with 40 series CVT set-up.
I love the build, but you’ll get a lot better performance if you flip your clutch around whether it’s the drive or the driven, they need to open opposite of each other to keep the belt aligned through its movement
How do you tention your chain with that mount?
2 -1 isn't too bad mine is 3.26 to one on my trans going to order 50 axle sprocket hopefully to get some speed out of mine with my current set up is 23.635 to 1 (trans ratio to chain gear ratio) I think lol
It also works really well with a 780 torque converter! It just needs to be geared lower.
Maybe if it were a v-twin 😁. In my opinion anything bigger than a 420/459 with a 40 series would make me just start looking at atv engine swaps. There is a pretty drastic jump in cost over 420’s.
A 40 series doesn't maintain belt alignment unless you flip the primary engine pulley around. Also the spring in the driven pulley is directional depending if you face the spring side inward or outward which also determines which way your primary needs to face to maintain alignmen throughout the speed range of the system
It works the opposite of a 30 series, in a 30 series the stationary or flat side of the pulleys are on the same side, on a 40 series the stationary side of the pulleys need to be opposite sides from each other to maintain your belt alignment throughout the speed range, your belt will last a lot longer if you maintain belt alignment
@@RomoRoosteris correct in this assessment. You can verify in comets 40 series instruction manual
Loved the build with the 40 series reverse gearbox. Do you think it would hold a built predator 420 engine? Thanks.
It is rated for 18hp, anything above that will need some testing. You would think a torque limit would be more definitive though…
@@KJRaycing ok great. Thank you very much. Love your videos.
nice job im sure you will sort out the power issue
Abom79 might be able to do some machinist work for you on the output sprocket👍
The engine is still stock… I think we can easily get back to where it was 🦾. Thank you!
Dang, pretty awesome gearbox if it lasts.
We’ll torture test it the best we can!
Hi kj raycing i have some honda odyssey buggy and i want to instaled a predator 670cc engine bit i dont know where can i buy the torque converter clutch and the gear box can you help me plz thank you
your smiling ear to ear having so much. a crosskart maybe in my future?
Man they are fun at any speed! My friends are speed junkies and still love the simplicity of a “go kart” style crosskcart.
I am going to attempt using a 90s polaris atv transmission, I have a 95 300 4x4 that is all chain driven besides clutch on engram side. Front diff constant with electric locking hubs. Heard of anyone using such parts with any success? Like your chassis’s and builds, your helping a lot of people.
I have the two stroke 400cc version of this with HLNR gearbox waiting to go into an XL frame! I think it is going to be awesome!
@@KJRaycing yeah this is a HLNR as well, I’ll be keeping an eye out for a video if you end up doing one with it.
Adding this transmission geared it down as you showed in the video. So maybe the "loss of power" is really a loss of wheel speed which would slow the buggy down and maybe make it feel less responsive.
I compensated for the gear reduction 10/60 to 12/40 so technically it should have been doing burnouts with a reduced top speed. The gearbox makes it feel like I’m running really big heavy wheel and tires. I just put the crosskart tires back on now that the snow is gone and I’m going to do a little cvt tuning before I upgrade the motor to get a solid baseline for that gearbox. Thank you for the comment, I kind of like trouble shooting and this is definitely and angle to look at.
What gear box is that and can it be used in golf cart fabrication is not problem for me
we have a crazy project planed for busco and i want to do a reverse gearbox on it but we are building a 25 or so hp 390 and we aren’t sure what gearbox can handle the power do you have any suggestions of what can handle so much power
It’s the torque that’s hard on the gear boxes. I don’t thing the 390 is putting out more torque than a 459 if that makes sense
More information on gear box like who makes it and how much power is it rated fore?
Information is in the video and in the description. I’m not sure how else to get the information to you guys.
mantap bang
Man that would be awesome street legal. Ever see any.deer with all that land
What was your top speed with the gear box?? Stock engine??
Great video!!
Top speed was 42 mph with the stock governor on the engine. Need to get some valve springs for some more rpm’s!!!
What kind of four reverse gearbox is that?
gm flywheel and a starter could probably be modified to work with this thing for reverse
25mm 6 spline bore sprocket (same as many production motorcycle sprocket's)
If you blow up that reverse box look at polaris atv transmissions. Polaris high low reverse transmissions are usually around $2-300 used.
I've seen a few behind mild motorcycle engines in buggies. I don't think they'd take Hayabusa power but easily strong enough for your predator.
I have a sportsman 500 I was planning to use for a donor and I agree with you 100%, but since this is the budget kart and I’m looking for upgrades vs donors I thought I would give this gearbox a try. Not too shabby and I still have the 500 for a future build 😁
huge? your wheels. are they golfcart wheels, and what is the wheel bolt pattern?
Hear me out.
Remove the center brake rotor. Move your brake rotors and caliper to the outside wheels. Now you can put a starter ring gear where the brake rotor was. Now install a mini starter on top of the ring gear. Now you have electric reverse.
That’s a really awesome idea!!!
Assuming the test pilot there is your son. We need to get him a mullet :D
Man that’s cold 😆. I fly with him and he’s only 14 years younger than me. And we’re not allowed to have mullets 😐. But if we could…
The torque converter driven unit is mounted upside down. Belt life wont be so long if you do this.
Just make one. I've got a big old snowmobile reversing tranny.😅. Dandahermit. Im looking at your two place side by side. Just wish for a 4 wheel drive.Guess I need a big 4x4 quad to build it.
could you do a high end build and compare things you like about it and not like about it and tell us if you have more fun on the high end 1 or the cheaper builds that would be very interesting on the pros and cons on both builds
Yes, sir! Just waiting for spring and the snow to go away. This is the fourth single seater and they all have different engines, a new “shootout” video is definitely due.
@@KJRaycing thank you they do say sometimes the things the FIA do takes the fun out of things i just hope its not the same
One of the clutches should be turned around to keep the belt aligned as it goes through the travel. The 30 series clutches are asymmetrical, one side of the clutches and belt are flat, so the same side moves on both clutches. On the 40 series, both sides are tapered, so opposite sides need to move to keep the belt aligned. From some reason, the instructions for some 40 series seem to show both moving parts on the same side, some instructions are actually correct showing them on opposite sides. Maybe the incorrect ones are just that the Chinese copied the design without understanding the design. Watch the belt alignment (in neutral) as the clutches travel through their range, you'll see the problem. This will cause major wear and power loss at higher speeds.
The secondary clutch uses ramps to downshift with more torque. Your clutch has dual ramps, so it will work both directions, but the torsion preload in the spring will likely work better in one direction. Therefore most people flip the drive clutch.
I had a manco dingo 13hp that came with the clutches installed like he has them and it worked - definitely doesn't seem ideal though, but it'll work until you start to have way too much power I suppose. I wonder if running them like this though, while wearing the belt faster, you may be pulling it tighter than the proper orientation, maybe less slippage? maybe negligible though.
And yes, there are 2 spring types for the secondary depending which direction you run it.
I love when I get comments about fixing my setup after I’ve shown video after video after video of it working perfectly with no broken or worn belts and cvt temps incredibly low. Thank you for the insight though, I will try your setup in the future but I think you may be focusing on the wrong thing. I wish you the best.
@KJ Raycing that's good to know, I also didn't see much belt wear with my setup, but I didn't ride it often. The original commenter was just stating the ideal way I suppose.
@@KJRaycing Yep, I am new to your channel, still haven’t watched all your videos.
I’m not new to the basics of CVT’s. Every snowmobile and ATV ever ever made, where they have done the Engineering, has the moving parts of the CVT on opposite sides to keep belt alignment. Even the Chinese ATV’s I have worked on have been correctly oriented. I’m glad your setup is working for you as is.
There is very little info on this on RUclips. Hopefully someone will post something. I can’t step up at this point as I only have access to the 30 series asymmetric style, and ATV style for slightly larger builds (I have 2 old Polaris chain drive transmissions with high/low/reverse). If I get a 40 series I’ll contribute to the community also.
Thank you for what you have shared, this is an amazing amount of info that my son could use for building his own. The pricing on your plans look extremely reasonable as well.
Can the budget kart run with a 670cc Predator V-twin?
Yes. They are all the same frame and can be outfitted with whichever engine you want!
@@KJRaycing Sweet! Thanks!
reverse is nice for sure hopefully when you upgrade the engine it will offset power loss.
We’ll get there whatever it takes. Problems are only problems until you find a solution 🦾
how can you adjust the chain ?? the engine could slide before you added reverse gear box .. does not look like the gear box will slide with the engine ?? I could be wrong ?
Check out the homebrew rear end video. The adjustment is in the rear carrier and the engine mount. There is a ton of adjustment.
I destroyed one of those gear boxes with a predator 420.. I did modify the engine to get max power but yea, it worked for about a week. Hopefully it’s not the same one I got, though it looks exactly like it and cost around the same
It’s not the same gearbox, there are VERY subtle differences; well at least I hope! Did yours use a 530 chain?
Hey bro i know you said it in qbother video. But what series or rouge fab bender did you purchage. Thanks
M600. RogueFab now sells a KJ Raycing crosskart package to take the guesswork out of what tools you need. Check it out!
Ok thanks man they don't have the 600 series is there's a difference between 600 and 601 or they pretty much the same ?
There is a KJ Raycing Crosskart build package. They are well aware of what I use. If you get that you can’t go wrong 👍
Just curious on hard it would be to make it 4x4?If anyone could do it...We all know it would be you.Keep up the great work.
I think I could do it and I would definitely take a crack at it. It’s the cost that keeps me away though, diffs and transfer cases are all expensive and I think it would also need a pretty good motor to make it snappy and responsive like the 2wd karts. Maybe someday though when I find the right donor 😁.
@@KJRaycing I would probably suggest an old yamaha grizzly with the push button 4x4 as a donor, usually can find those pretty cheap, modify your ride height for a shaft going under ya to your feet for the front wheels, could use a hand button or even a foot button like they do in gators. just an idea...
I think your losing power due to the number of teeth on your sprockets. For instance If you have a 10 tooth driving a 40 tooth,, and you switch to a 12 tooth it needs to drive a 48 tooth to maintain the same gear ratio
Where did you get the gear box I want one for my project with a 420 big block predator with 40 series on it.
Info is in the video and in the description. I’m not sure how else to get the information to you guys.
@@KJRaycingwhere are you living at what state & town I live in Jackson S.C.
I seen snow in your videos so it must be north or west of me.
I have worked all over the United States from homestead Florida to Hazelton Pennsylvania out to Tioga North Dakota it was a good life but a hard life on my family and I. But the money was good to support my two Boys&Daughter oldest son is 31years old daughter is 15 years old now wife is 50 now
Do you know of a reversing gearbox that could handle a 50hp four cylinder motorcycle engine
RPM gear boxes.
Buenas tardes amigos
Que precio tiene tu vehículo tu crosskart amigo
You are creative, my dear. .
Can I give you some suggestions!
Your channel has zero content, this should be interesting......
@@chrismustry9302 Yes, there is no content, but I have some ideas to offer you
Can I use a 212cc engine to build a cross kart?
Well yes, it will be a similar speed as a 212 go kart. Maybe 30 mph top speed. But you’ll have awesome suspension 🤓
Do you have any kart frame blue prints for purchase?
Yes sir, check the description for all if the links or you can find them here kj-raycing.dpdcart.com 👍 Enjoy the build.
@@KJRaycing thank you buddy
I'm at 6:07 and I would just get rid of the plate flip the secondary so the primary run with each other and not put the belt in a bind.
I’m not sure there’s enough shaft for that. I’m going to do some cvt tuning and some engine upgrades, stay tuned!
I added reverse and had to completely transform the rear end on my buggy
Reverse is a tricky thing for sure. It’s either expensive, complicated or both! This box so far has been affordable and not to terrible to use.
I’m surprised how much power it zapped from your kart.
Check the newer video… I was mistaken. The main jet came loose during the gearbox install, it still has tons of power! I can’t update videos on RUclips but I did put it in the description.
Does anyone know where we can get this reverse gearbox? I can't seem to find any
Description. Check the description of the video if you want information about the video. The gearbox is on ebay and sold by Blast LED as the description reads. You guys make me crazy!!! 😁😁😁
MBI karts sells 530 series sprockets hub drilled for sprocket hub sold at Gopowersports with 3¹/8" bolt pattern out of Texas.
You might have drag from the spacers not riding on the edge of the bearing correctly
Yeah I think the cvt could use a little adjustment, good call.
Can this work for a 140cc 4-stroke go cart enginw
Yes
@@KJRaycing ok thxk
Heck, I like the budget build the best. I'd let anyone drive it. Reverse isn't required in my opinion. It may be nice to have, but not necessary.
Thank you and I totally agree! I put reverse on it to see how nice/necessary it would be and to hit some serious trail. You are absolutely right that it is not needed but it is at least pretty cool.
The easiest solution would be to flip the drive clutch on the engine
My I love the channel, but I’m sure you already figured out your clutch is backwards. You either need to flip your primary or your secondary either one would make the clutch set up, correct
Thank you! When the clutches are engaged the belt is straight, when they are disengaged it is not. I’d rather have a straight line pull under load than at idle.
Кто разбирал этот реверс, есть к нему видео или чертежи общего устройства шестерён
whats the top speed ?
There are a lot of factors to that question. The main one being an upgraded ungoverned engine. I’ve gotten up to about 45 on the stock 3500 limiter. If you’re willing to sacrifice burnouts and low end fun or get the motor to turn 5-7k rpm you could probably get 60 or 70 out of it. A combination of both could get you more.
I love it. But feel like it lost some of its Punch
It definitely has… but it is a new challenge and the engine was due for some simple “massaging” anyway. Governor delete and a mikuni carb should get it right back where we want it 😁
Is there a link to the gearbox?
No link because they are sold on ebay like the video says 👍.
Got the gearbox...what's your top speed on that?
That box is bigger than mine. Hmmm??
If you had a lathe you could’ve made a new shaft for the reverse box
I would love to have a full on machine shop, but I like finding solutions that don’t involve expensive tools. This channel was started because of guys like me in garages that wanted to build. I try to use simple methods with the simplest tools possible to make amazing things. It is a very fun challenge. Thank you for the insight and the comment 🦾
🔥🔥🦾🦾
Get a hold of Sprocket Specialists they can make a 6 spline sprocket to fit.
I ordered my rear sprocket from them. It was shipped yesterday. They were very good to deal with.
@@williamlanphar630 Yes sir they are my go to sprocket supplier if i can not find it else where.
520 chain is better anyway, plus most motorcycle engines already use 520/530 so could maybe use it with those - at risk of blowing it up lol. Thank you for the tip though, I'm going to save their website for my cb350 engine build.
@@M.TTT. I am running a 530 racing chain on my Honda Shadow 600 V Twin powered mini buggy and it holds up great. What KJ is saying is he wants less rolling resistance so he's switching to a smaller chain size. And no problem glad to help.
@@FukTheGovernment465 ah true, but a well-cleaned/lubed 520 vs 420, KS there really that much of a noticeable difference? Interesting how much it could be, I would think the gearbox having assumably sprockets and chains or bevel gears would add more rotating mass, maybe a thinner oil?
I enjoy your videos I like the way you go about things give a man a fish feed him for a day teach a man to fish feed him for life nothing but respect for you and you family. I was a pipewelder and pipiefitter by trade for 28yrs before a ATV accident 05/06/2018 it changed my life as I knew it I was forced to retire from the pipe trade I was in truma icu in a coma for three months then was transferred to

My son is 25yrs old he balanced the rotating assembly with my friends help and watching him he is learning alot along the journey.
If we get plans from you and build your VF2 &VF1 carts he will be the one doing the physical work but I also have a young man like my son we will also build one for him if that is OK if not let me know he has put street bike motors on golf carts not to safe on a golf cart at 105mph.he got rid of golf-cart thank goodness before something bad happened.

easy reverse: a car starter motor
I think a car starter motor could be more complex… you have to find a matching flex plate/flywheel to mount to the rear end, a bracket to hold the starter motor, tuning and aligning the bendix and getting the perfect gear mesh to not destroy everything when you use it. This gearbox is probably cheaper than the R and D plus parts of a starter motor reverse. But yeah, clearly you have tons of experience with it, right?
very interesting idea, would definitely need a good/larger battery, maybe a secondary battery even, and very good charging system.
If it's that easy, how many have you done?
@@chrismustry9302 if this is youtube, how many videos have you done?
@@atsekjoker sick deflection attempt, bro. I have about a dozen more videos on my old account than you do(a whopping ONE lol), my current real life doesn't allow me the time to film and edit content. How about that 'easy' reverse setup you've obviously mastered?
Possible dumb question....
Can sprinkler pipe be used for a roll cage? Orif not, where can I salvage the right metal and/or what am I looking for
All depends on how fast you want to go… I’d say sprinkler pipe would be good for around 15mph. You are looking for DOM tubing with a wall thickness of .095 if you want to go fast 👍
If cromemoly tubing .80 if Dom mild steel I would run .135 wall for high speeds NHRA roll cage specs for drag racing cages.
In case of high speed impacts on track with concert wall.
Sprinkler pipe is carbon steel seamed pipe it should have a grade on it to tell specs of pressure use for water psi internal use to transfer water at high pressure and volume to control fires and protect investments.
Sprinkler pipe is scheduled 80 pipe for treading and is very heavy for a chassis.
I think your losing power due to the number of teeth on your sprockets. For instance If you have a 10 tooth driving a 40 tooth,, and you switch to a 12 tooth it needs to drive a 48 tooth to maintain the same gear ratio
I need to do an update on this video… power turned out to be just fine, the jet was loose in the carburetor. I kept the same gearing even with the 1:2 gearbox so acceleration and top speed are the exact same. It is actually a freakin riot to drive and the gearbox is awesome. I’ll do an update when I finish the video for the engineered jump I’m building. Thank you for tuning in 👍
