my sons first Tamiya buggy. at Christmas. so cool.
Nice, great first cars.
I would have killed for this when I had my Grasshopper 2 back in the day. It was my first hobby-grade RC car, and I've got some fond memories of going up against folks with RC10s and Losi vehicles.
Dude me too! I wanted something like this so bad.
WOW! The Outtakes REALLY show how much abuse that it can take!!! 😲😎
I forgot about this one. I want to get either the Grasshopper II or Rising Fighter - and do THIS.
I saw how the second design update was necessary. Version 1 had the upper Rod out of line with the Lower Arm - creating Negative Camber gain on compression. Glad you fixed it. 😉
You know what Alberto? I AM another one of those NUTZ who enjoy tinkering and reengineering Tamiya's bottom end line. 😜
I just don't have the Engineering background, or ANY CAD skills, like you to actually be able to DO this.
So I'm glad you're out there, doing what you do, for the rest of us!!! 😁
Hey.... About a year ago, you mentioned a couple of times that you were going to design a King Blackfoot type Front Suspension for the ORV Chassis............
Any closer?? 😁😁😁
Carmine ✈🚂🚙
I have not but I promise it is on the list!!! I need to do that soon!
@@AMPROEngineering AWESOME! The ORV front end is the only thing that I really don't like about it.
They finally got it right on the KBF, but the populous didn't appreciate it at the time.
That was great! Would love to see more slow motion video, showing stock hornet and rising fighter vs full modified hornets and rising fighter suspension working.
I like that idea! I really should have done that but my Super Hornet and RF are both in work. Soon as they are done I will do that.
this makes me wanna go get a tamiya model again :)
Now that is a compliment!
thank you for making these!! i just got a grasshopper 2 and i cant stand it when it reverse
Neither can I. It is absolutely irritating to see that
Looks very impressive. Good job on those slo mo jumps, showing it in action. Would really wish, for the looks, that those extra mounting holes on the uprights weren't there though. Would look more 'stock' if the uprights where shorter. But it works the way it is :-) Would love to see it mounted on your Hornet III RF. I think with everything AMPro mounted + a fix for the rear slamming, the Hornet III would actually work better than the DT-01. That would make it a real Hornet III - defeating the Super Hornet's replacement :-)
I agree with you on the holes but I felt that it was more important to have consistency on minimizing parts should someone have multiple of my front ends. Currently, every front end I make uses the same uprights. I just ordered a set for the Hornet 3 (Rising Fighter) in red. My next side project will be the trans pivot. That will be an easy one. The GH2 is also easy but the Super Hornet seems to be a massive challenge. You would think it is the same as the GH2 but the rear mounts on the shocks screw up the geometry. It is a bad design.
AMPRO Engineering Never had a Super Hornet up close and don't think I ever will. But I'm ready to transform my RF into a Hornet III :-) ... once I solve the problem with the rear Rolling axle. Saw a solution with a fishing line on a Hornet that might work with the RF as well but prefere a more visual pleasing solution. Keep up the good work.
I should have this done soon.
AMPRO Engineering Sounds very, very good :-)
such a brilliant video, make Rc cars sir.
Thank you
Hmmm.
I wonder if you have thought about a kit that includes these GH2/SH/RF lowers & uprights with the upper from the GH/H, for the Hornet/Grasshopper.
When Combined with the GH2/SH/RF inspired rear kit, & the battery/trans retainer & new door, they should work out nice.
I think I need some clarification on what you mean about the lowers, uprights and uppers for the cars. I am intrigued.
I am looking at doing a crazy Hopper/Hornet build.
My idea includes:
The front) Your Super Hornet lower a arm kit but using the Hornet upper control pivot and a Tamiya M04 (or Traxxas Bandit/Rustler) steering knuckles, either would likely need to be slightly modified to fit your uprights (c blocks), but they would allow modern hex mount wheels.
The rear) Your (Super Hornet inspired) Hornet lower rear suspension mount, Hornet battery tray door, Hornet battery tray door retainer (which one depends on what gearbox I get), Hornet shock & wing mount (depends on whether I use a Hornet or Cyclone/Manx body), & Tamiya aluminum hex mount adapters for the Frog.
Basically I wish to mix n match parts from your Hopper/Hornet & Hopper2/Super Hornet/Rising Fighter front suspension kits.
Of course with plenty of parts and mules, you could probably try it out yourself (& possibly fix any errors while improving on the idea).
What do you think?
Wow, the length people like us go to to mod an old car. I love it. Well with that kind of mod, I would say that the upper link be changed all around and not use any of the designs simply because they had constraints that you probably don't need to worry about. I think that a version of the Hornet center control pivot is what you would need. This project sounds amazing!
Yeah, it is an odd passion.
But I am this way with RC cars, Hot Wheels & even the full size things, stock is fine, but sometimes, things need updating or just plain personalization.
I also have an old Traxxas Bullet that I am restoring & an old Bolink Sport '91 {Jammin' Jimmy] that I am resto-modding, finally found an easily obtainable way to update to hex drive wheels thanks to servo city.
Same here. RC cars are a secondary passion of mine. Number one hobby is full sizes cars but I need to tinker with everything. Thankfully my wife is the same way. I know the Jimmy you are talking about. Two of my friend had those when we were kids. So fast!
looks great, i kinda want to dive my lunchbox off my roof now.
LOL!
I am thinking that I may invest in a grasshopper II, get this upgrade and get some mad max designs to it.
The GH 2 is a cool little car. I like mine but a more useful upgrade is the trans brace I made for it. It keeps the car quiet so budgetarily (is that even a word) speaking, I would go for that before the arms.
Haha, cool. It is a great car even stock.
Hi did you know that you can change the hornet front arms to the grasshopper 2 and put oil filled shocks on the hornet?
Yes but the offset is wrong and the angle of the shock is no longer lined up. I also hated the camber gain.
Those jumps......landings looked impressive! Even the off balance landings handled well. That double upper control arm mount looks MUCH stronger than the single one in the other kits....
Any chance of a double brace for your other Buggy kits?? 😲 😲 😲 😲
And, do you have a Novak ESC AND a Tamiya MSC in the SAME car?? I don't know if I'm seeing things.

Well it all has to do with how the load is applies. The upper link on the Hornets is very durable because of how they absorb impacts. The one i call the cosmetic upper link is very weak but as the name implies, it is there for cosmetics, lol. This one here did turn out to be stronger than I anticipated and I love that I have to make no mods to any part of that body or chassis to make it work. You know me and cutting stuff...i hate that.
Lol and yes, I have MSC's in almost all of my cars for both cosmetics as well as a way to get them out of my drawers. I had around 30 in a drawer that was just for MSC's. I needed the room so I tried to sell them on ebay but no takers. Then I said screw it and installed them all as a way to get rid of them! Problem solved.
Now THAT'S some method of clearing stock!!! 😁 😂
Yeah, the upper link on GH II, SH & RF just LOOKS more secure to me...
I just like the look of strength.
I hate to pop even MORE ideas in your head, but if you lengthened the upper tabs on that piece - as an OPTION for people who don't mind putting holes in their vehicles....
That extended upper tab could have a second hole, to mount it with a screw, to the shock towers.
I only did some basic math, but it appears that it would make the whole front assembly STRONGER than stock!
Whadd'ya think?
Interesting thought. I see what you are saying as it would secure the whole thing much better. I need to investigate that. Well thought.
I've been good with theory throughout my life....
It's the execution that often gives me fits!! 😁
Fortunately, I now know someone, well versed in CAD!👍👍😎
these are the arms I had in mind over stock old narrow hornet :)
Would this suspension mod work on a Grasshopper 1? Do I have to modify the chassis or the body? I'm thinking about purchasing the set.
No, I make one for the Grasshopper but you will need to mod the body.
I don’t remember if I asked you,
1 do you recommend dummy VW engine for the Hornet.
2 can you recommend road wheels and tires for the Hornet?
Just for playing in the church parking lot, I can’t afford a road car.
1. I dont know of any but I am making a ford 2.3 for the hornet gearbox. 2. No, I use the factory ones since I like how they tires look, they wear down pretty quick.
@@AMPROEngineering Thank you, your comments and knowledge is not wasted on me 🙂
Low gloss black aka satin black
Well they make a satin black also. Low has more sheen than satin.
Great work. So you have a link where i can buy the right ball studs and Cups?
No, there is no great place. I use ebay and you know how those links keep expiring. Just 3mm threaded ball cups and matching studs. I use threaded rod for the links.
@@AMPROEngineering OK thanks. I think i found some on Tamico. Cant wait to get my double wishbone front suspension. Would you say that the items 124002-01 and 124002-02 on shapeways are a must have for an GH2? What do they improve?
@@AMPROEngineering Today i received my double wishbone suspension. 😁 That is so awsome. It doesn't make any sense to invest that money in that cheap little car. But it is awsome. Can not stop smiling when i look at it. Thank you very much. Well done.
Have you improved the shock tower on the grasshopper 2 mine broke the only way to fix it is to replace the original chassis
No i have never touched the tower on the GH and Hornet. I have a plan for a brace though.
Is that a novak super rooster your running on that?
Weirdly, yes. If you noticed the 380 motor in the car, you can see what an odd choice that was.
AMPRO Engineering nice i had one but was playing with it in some mud puddles and it fried:( oh well live n learn will definetly miss it though was a great esc.
Oh jeez..yeah electronics used to be very susceptible to moisture. Not like these new fangled ones lol
And in between the back shocks that white board with wires in it? What are those? I've seen with and without?
That is the resistor for the mechanical speed control which is not used any longer.
Just came across this awesome mod, thought to myself "I got to have this !"
So was fully prepared to buy a few sets, but then I went to the site and seen the price....... O.O
Honest question here: why is this so expensive ????
Seriously, I think for the price they're, there should be no cleanup needed to the parts before installing and all parts required included in a complete kit !
Am I missing something here ???
Well, that is just what 3D printing costs right now. This time last year they were $5 more expensive. Injection molded parts would cost 10 times that since the quantity needed is so low so the printed parts are by far more viable. Ina few years price will drop even more and materials will get even better. 5 years ago when I started this, the suspension would have cost $100 or so! Crazy how far it has dropped and what materials we have now.
Thank you for the explanation, I don't know anything about 3D printing and the costs involved, I may wait for the Grasshopper / hornet front end to come down in price one day.
The Lunchbox front end seems a little more reasonable, but I suppose there is less material there as well ?
My trouble is, once I have this kit in one of my cars, then ill want it in all of them ! LOL
Which will add up very quick and be very costly.
The LB has fewer parts but the front tires and added bulk make the parts more vulnerable to damage so I tell everyone that they cannot run anything but a silver can. Ill have a video soon of my Pumpkin at the track with these arms.
Very nice
Which filament do you use and which printer?
The surface looks amazing!
I don't have a printer. I use shapeways for everything but a friend of mine has been showing me the joys of his FDM.
@@AMPROEngineering its an amazing hobby/technology I love my printers BUT as you should be able to tell from this guys question you will never get quality like that from an FDM printer. Just wont happen. And im pretty sure ive heard you say you print your stuff out of nylon?...yah good luck with that with FDM. PLA is an amazing strong plastic and ubiquitous but its a lot like glass, strong until it aint.
@@yourapeeinguy8263 Totally correct. They can be mechanically sound but the cosmetics are harder to get behind. Yeah, almost everything is nylon or the new HP fusion. LOL! Yeah, strong till it aint is about right.
So I just got one. What's with that board in the back with wires under it and the other servo??
That is a mechanical speed control. This is what was used 30 years ago. They were all we had and they were terrible but I have an entire drawer full of them so I install them as decor.
What front suspension are you running on your GH2? It looks like the same suspension that is on the Hornet in your other double wishbone video.
So this suspension is a full Ampro design. There are part numbers in the video and in the description there is a link to my store where the parts are. I cover the install in this video along with all the hardware you need. If you have any issues, email me at amproengineering@gmail.com
@@AMPROEngineering I realized that I did not specify any reference components. My fault. I was hoping you could tell me what shocks you are running on those cars. Apologies for the vague question.
Do you do a roll cage for the hopper 1
No, the Hopper does not need once since the body is the structure. The lexan Hornet body loses all the support the hopper was intended to have.
I would pay 58 bucks for the whole kit. Balls, cups, thread rods, and whatnot. Some of us Dad just don't have the time to go and sit down to source all these items. Can't you come up with something? Before someone uses your parts to make complete kits and sells them under your nose. please help a single Dad trying to get my cars in working order.
Im really sorry man, I just do not have the time.
