e35: 3D Printed ORV Rear Double Wishbone Suspension

[@garyhenke806]

this stuff is amazing to watch man!!!!!! was into Tamiya cars 35 yrs ago, and still have the original frog, f150 hot shot and another gold wheeled something. was great to build them back in the day. and with todays technology a persons brains and ideas we see what can be done. AWESOME!! thanks for having such a intense desire to make parts better!!!!

[@AMPROEngineering]

Any time man. I just want all the parts that i wanted as a kid! Now I can finally have them

[@addiemonsterrc3990]

All my parts just shipped, so stoked to get this all together! Went with red/purple~

[@AMPROEngineering]

Oh nice!

[@geniusanthony]

Viewer number eight, four minutes after upload! I have to tell you Mr. AMpro, I look so forward to you videos. Thank you for all the effort you put into these videos and your products. I have yet to obtain Tamiya beyond my new-found missed childhood TA-01/02 obsession. I specifically enjoy being able to nerd out on rc away from my own workshop, so kudos on allowing me to live vicariously through your exploits.

[@AMPROEngineering]

Oh it is my pleasure! I am happy you like them. These upgrades are all things I wanted to do to these cars since I was very young. I am happy to finally be able to create the upgrades I always wanted.

[@nelsonapontejr.6793]

I can wait to see this completed, and for the parts to be available! I live in the northeast and want my original Blackfoot to be my winter project with these parts. Keep up the great work!

[@AMPROEngineering]

Thanks man. I will post a killer running video as soon as I can get somewhere with more than a curb to jump off of!

[@muddfoot69]

I have an old Blackfoot in a box and a re-release runner monster beetle....looks like they may be getting some new life

[@AMPROEngineering]

I am glad to hear that. They are great cars.

Did i really say that? Sounds like something I would say.

[@leonridgewell7484]

Nice work on the rear suspension build! Tamiya should of done in the first place i reckon.

[@AMPROEngineering]

Yeah the trailing arm was fine on the frog but with the big wheels, it really messed up the geometry.

[@gregoryguza4623]

That setup is absolutely awesome! Please let us know when you get the rigid upper arms out there. I'm definitely going to get this for my Subaru Brat. You are a genius for fixing the well-known issues with these Tamiya kits.

[@AMPROEngineering]

Thank you! I will let you know. It won't be long. I'll make sure there is a video too!

[@gregoryguza4623]

I was just looking in the Shapeways website and I couldn't find this upgrade. I only saw the front arms and the front bumper mount. I'm guessing it's because it's so new that they didn't have a chance to post it yet?

[@AMPROEngineering]

I am still testing them out. Its been raining and I also need someone to video for me. I just need to make sure the parts are tough!

[@gregoryguza4623]

That's cool. It's always better to be sure first. Take your time. I'm looking forward to seeing the video.

[@AMPROEngineering]

So I think there will be some upper rigid links coming out. It will cost more and take more specialty parts but I cannot argue what people are saying about how accurate it well look. I think I need to suck it up and make it happen!

[@martineps6223]

cuz at the same time I will order some of the other parts too to make the front end real nice

[@AMPROEngineering]

Cool man. What is your wishlist?

[@martinneps9387]

@@AMPROEngineering How can I find out exactly everything you have for the Blackfoot trucks that you did 3-D print Please comment back I wanna make my trucks better if I'm still waiting for the king Blackfoot parts Thank you very much

[@nfarc7542]

That set-up is awesome. I wish it could be put together for closer to $50 so I could justify it. Nice work though!

[@AMPROEngineering]

Yeah I know, prints are a little pricey still but 5 years ago this setup would have cost $500! They are getting cheaper every day...

[@billgoodspeed4381]

Can you add ampro decals with this setup so we can pop em on our trucks I love your products......

[@AMPROEngineering]

I like the way you think! I am actually working on getting some made. Ill let you know!

[@frankiechow39]

Hopefully you can offer a kit to convert the battery door to the brace for the Boomerang like what you have done to the Frog. Of course, the side would have to be modified for battery changing.

[@AMPROEngineering]

Actually, i am. I have a hotshot that I am building now and it will need that battery area totally changed.

[@frankiechow39]

The Boomerang and hotshot battery section is quite different. But the Boom is stiffer.

[@Belyaztacadel]

I've been watching some of your videos lately and I am very impressed with all the transformations and add-on to old vehicles. I will be visiting the web site (Shapeways) soon just to browse your products and see if I can find some updated parts for my Tamiya Jeep Wrangler. I would love to make changes to the rear suspension and make it kind of independent suspension without sacrifice the differential. I'm also looking for sturdy front knuckle arms. I have owned the vehicle for two decades now and it has been in a box for almost 15 years. Looking forward to find great products for my Jeep. Thanks.

[@AMPROEngineering]

Thank you very much Delfin. Good news it that lots of companies make parts for the CW01 Wrangler. I do not as that is pretty new for me (considering how old that model is you can see what I think is new) but RC4WD and eBay are splattered with parts for that model. You will have no problem with upgrading that bad boy!

[@efremkiel8798]

very very cool! looking forward to the driving footage :)

[@AMPROEngineering]

Sheesh... me too! It's been raining

[@GhostofTatooine]

Wow, you were not kidding when you said it was a tight fit. Done now though. Very good looking prints and very strong. Pricey to the UK, due to import taxes ect, but well worth it. My issue now is, I had bought aftermarket Aluminium shocks and they were fitted horizontally. Now they fit vertically onto the new hubs, the ones I have are way too long. Any idea what length the shocks sould now be to get the best fiting and suspension travel?

[@AMPROEngineering]

Yeah that is a shame it costs so much to get there given Shapeways is located in the Netherlands. The shocks needed are 80mm. That is what the stock ones are so maybe add some internal spacers to get the eye to eye length at 75-80mm. Email me at [e-mail] if you have any issues.

[@GhostofTatooine]

@@AMPROEngineering yeah, weird. They say if it is more than £135 then I am an imported and have to pay the duty. I guess it is to do with where you are as the designer rather than where they are as the maker. Anyway, glad it is now done. Have the shocks so will be installing them later. Have a 2S lipo to try out too but will probably not go Brushless. Seen some videos and it just seems a little to uncontrollable for my liking. Anyway keep up the good work and if you ever get the .STL files out for sale I may print some of my own stuff from you.

[@civicdaniel10]

Simply perfect !

[@AMPROEngineering]

Well thanks!

[@raymondgard5098]

Shapeways shipped out my order for this project...been wanting to do this upgrade for so very long. I need to know where you got them Ball Cups. I have always thought the stock ones are trash and never have found a great substitute for them

[@AMPROEngineering]

Awesome! Send a pic when done! So everything was located on eBay. Search 3mm ball stud and usually they come with cups. Just make sure the shaft is an M3. For rods i just used m3 all thread, also from ebay.

[@elsdp-4560]

THANK YOU...for sharing.

[@AMPROEngineering]

My pleasure.

[@billgoodspeed4381]

In used washers on my front double wishbone suspension for my pumpkin.......👍

[@AMPROEngineering]

0.5mm ones? Those are what I usually use.

[@GhostofTatooine]

Hi, awesome upgrades for an absolutley ace car. Still inspiring people after all this time too. Just so you know, all parts required including the battery doors in a mix of black and red are priced at £124.00 shipped in the UK. Quite a lot. Do you sell the .STL files for home printing?

[@AMPROEngineering]

I do plan on adding them to the Ampro Myminifactory but I am stuck at the moment since I dont have my cad tool anymore. I am getting a license soon and then I can add them there! Stay tuned.

[@ocularcavity8412]

Very well designed i can't what to see what you make for the bandit

[@AMPROEngineering]

Lol me too. I need to get moving on that. I have a video showing the body work almost done.

[@Zack-nj3ej]

Do you know if the original Tamiya Bush Devil has a similar rear end? I would love to find one. I really dig the early 90’s color graphics on that truck. Sorry, that was off topic. 😂🤦🏻‍♂️

[@AMPROEngineering]

Yes, the bush devil came out with a revised transmission with double wishbone suspension. That then became the Super blackfoot and it was revised again for the KingBlackfoot. They are solid transmissions and rear suspension setups.

[@Zack-nj3ej]

@@AMPROEngineering then I’m about to Indiana Jones myself an original Bush Devil! Thank you again for all the great info!

[@popeb69]

What a fantastic product. How has the material been standing up? I will be ordering the Blackfoot rear and the pumpkin front heavy duty camber

[@AMPROEngineering]

Its been great. I have two ORV's with this rear end, this one and a Frog. Both are running hot mods (something I do not recommend) and have had zero problems. I do not abuse or bash them but they certainly are jumped!

[@popeb69]

Ordered my parts yesterday from shapeway!! Does that disc come with the transmission brace?

[@GhostofTatooine]

Quick update. Now decided to purchase the parts to modify our Monster Mini. Should be good.

[@AMPROEngineering]

Sounds like an awesome project!

[@GhostofTatooine]

@@AMPROEngineering need to order some hardware bits and pieces as I don’t have many spare parts. Looking forward to putting it all together

[@geniusanthony]

not to nitpick but... at 13:00 you mention a 3/8 drill bit. 3/16 is what I believe you meant

[@AMPROEngineering]

No thank you! I need to know that stuff. I meant a 1/8 was what I meant. It is 3.175mm. Ill make a note in the video when I go home.

[@AMPROEngineering]

OK I made a note. Thank you again for pointing that out!

[@carbonitegamorrean8368]

had to go back to E28 & e34 in the middle of this...lol...I watch all your vids regardless of content (rather I have or like the chassis or not = but (I like ALL Tamiya hard bodies)) I have a Blackfoot(s) chassis (in running order & another in a box "parts" cause they don't interest me), also a King Blackfoot. I acquired all for the bodies at the time. Actually wish I could get rid of them. That all said, ; you have made the "ORV" worth having if someone was interested in spending the money & time on them, good on ya.

[@AMPROEngineering]

Thanks man. I am all about the oldies!

[@DirelectRC1]

Great mod! Awesome web site man. A lot of great stuff on there

[@AMPROEngineering]

Glad you like it! They are a lot of fun to design.

[@morgan8m]

Great Stuff. Can't wait to get it installed. And you are correct, I can't keep my dogbones from coming out using the standard suspension. Also, what is the rough/actual length of the upper links with the ball cups installed?

[@AMPROEngineering]

Yes, you can keep the dog bones. As for the upper link, center to center it is 45mm

[@morgan8m]

@@AMPROEngineering I'm sorry. I meant I was experiencing the same thing with my dog bones from slipping out, as you demonstrated. However, I just installed the new suspension with the stock Blackfoot shocks and for some reason the arms are really hanging low as if the shocks are too long which is still making the dog bones slip out of the drive cup. Any thoughts?

[@scottmills2627]

That's pro work man

[@AMPROEngineering]

Thank you!

[@estefanopassatore8150]

May you do the same thing for the Buggy Champ and the Fighting buggy?

[@AMPROEngineering]

No not at this time. Someone else used to and they were all machined aluminum.

[@CarmineRC]

You have just made me want to get the new Blackfoot!!! 😁 👍 👍 Are you planning a King style front double wishbone setup too??

[@AMPROEngineering]

I have thought about that but I have started to improve on the original design of it and right now it is really working well on my test truck!

[@65BAJA]

19:16 Could you drill the chassis boss out and run that all thread through, then use a nut on each side?

[@AMPROEngineering]

Technically, yes that would work.

[@UlisesBatalla]

Can you please put this together as a kit with all hardware and keep it at a reasonable price

[@AMPROEngineering]

All costs are set through shapeways as they print them. Sadly I do not have the time to make kits.

[@billgoodspeed4381]

So can't wait to pop this on my monster beetle......

[@AMPROEngineering]

Soon man, soon....

[@joefugate2215]

I'm beginning to think there is something wrong with my chassis. The chassis brace lined up perfect. All three holes in the transmission lined up perfect. Wha'd I do wrong??? Also I was able to use a washer on both sides of the suspension arms.

[@AMPROEngineering]

What's the issue that you are having?

[@joefugate2215]

No issues. .....was joking because everything lined up perfect without having to stretch anything. I do have a question the turnbuckle though....what is your distance center ballstud to ballstud?

[@AMPROEngineering]

OH! Haha! You had me concerned! I can't tell you off my head but as long as the upright is perpendicular to the ground you are good. Remember to test the travel with your shocks before you add oil to them. The rear suspension can bind the axles if the shock is too long. You may need an internal spacer (I used a 2 mm spacer in mine).

[@joefugate2215]

I measured the distance of the lower control arm mounting points (45mm) Then bounced the car a few times and put a carpenter's square on the bench to make sure the tire and rim had 0 camber.

[@AMPROEngineering]

0 to neg. 3 is good. I usually go to around -1.5. Helps on turns but isn't that noticeable.

[@PeasantArt]

Love your vids. Just ordered all of your Monster Beetle suspension parts. Are rigid links available for sale?

[@AMPROEngineering]

Oh thanks! Hope you like them! I don't as the adjustable ones you make yourself are way better for handling. I could make them but they wouldn't work as well without slight negative camber.

[@Artax2040]

I really like your video, your job and those developments, but at 190$ for 4 parts, It s a little bit too much to revive my old new beetle from 86. At 100$ box for the set, I think I will buy one (but not at 200$). Currently, I ve just bought original rear parts for 30$, and I think I will improve them. But, I still want to say great jobs !

[@AMPROEngineering]

$190! Why so much? Isnt it like $90? Is shipping included? Shapeways sets the prices but I also have them all at my mini factory for home prints. Yeah they can be expensive, i agree.

[@edwardmatthews5899]

How long did it take to 3d print the bulkhead,subbed man you do some awesome work.

[@AMPROEngineering]

Jeez, no clue. I have shapeways do it all. Way easier and cheaper than me having to deal with it. I can imagine it would take 6-8 hours.

[@Jimreynoso]

I’m looking to buy a small $100 3D printer from eBay and start experimenting with it. My question to you is, how difficult is it to developer the file that will tell the printer what to print. I’m looking to print rc car parts.

[@AMPROEngineering]

I've bought around 20 printers and given them all away. I find that it is not worth my time to have to set up and maintain these printers. This is why I swear by shapeways

[@giuseppeveneziano1000]

This is amazing engineering, sir. I'm new to your channel, do you address your background in any previous videos? it appears that you design the parts then send out for printing? What software do you use? I've just become a giant fan, thanks for the outstanding work.

[@AMPROEngineering]

Thank you for the kind words Giuseppe. I do not talk about my background but I must say that it might make a good video soon. I am a Senior Mechanical Engineer at one of the best product design firms in Silicon Valley. I used to design pharmaceutical machinery but now have moved on to very high tech consumer products. I do all my own designs and then prototype them in house. From there, all parts are sent to Shapeways.com for production prints. I used to use Solidworks from 1998-2010 but then got fed up with the inability to deal with even the smallest of assemblies. I moved to Pro/ENGINEER in 2010 use it to this day (now it's called Creo). I have some awesome stuff coming soon so keep yours eyes peeled!

[@muddfoot69]

Thoughts on adding a hinge pin with E clips vs a screw pin on the arms? What measurement would work or What size screw pins do I need to complete this?

[@AMPROEngineering]

You are welcome to but they are usually designed to the application by the manufactures, something I am not able to do. You are looking at 2 35mm units for the main pivot and then 28mm untis for the knuckle. This is from the inside of the c clips.

I have a bunch of Tamiya 5mm ball studs... ..however when I got to attaching them they are too short!...where do you get the longer ones?...I Found these and looks like they will suffice-Duratrax Ball Stud Long Evader ST..Is that what you used?

[@AMPROEngineering]

That is so annoying! So I use 10mm shank ball studs. They seem to be long enough for everything I use. My recommendation is to ask a guy at the hobby shop but they look at me with a blank stare and then ask me what kit it's for. Look on ebay for a ball stud with a length of 10mm (threaded shaft). I will look for an auction and post a link.

[@eddieleon5548]

I ebayed the duratrax ball studs and ordered 4..dimensions look like they will be just perfect length..In your build video I would suggest it's imperative to drill the 2 holes for bulkhead that attach the Arms first, before attaching to the tranny..Wished I had before buttoning everything to the bulkhead. Just thowin it out there bud.I think its going to be ok tho.

[@AMPROEngineering]

Did I not? Maybe it is because I forgot to when I assembled mine too. I like to do these on cam the first time as I want to run into the problems that someone else does. Sorry bout that!

[@ecto1a2003]

what size ball cups should i get. i ordered the right size ball but the hole is too large for a 3mm shaft.

[@AMPROEngineering]

Well the ball cups I use are 4.8mm units. Kyosho makes nice ones I get on eBay. As for the studs, correct, the hole is 3.0mm so that you cannot thread into it. It isnt going to be able to hold a machine thread in place. so you need a nut on the back side of the ball stud (if I am following you correctly). 10mm long, 4.8mm diameter ball studs are what you need. Does that all make sense?
