- Its already 2 years ago since I released my trailing arm conversion kit for tamiya Grasshopper (and hornet also).
Developing the kit was such an enjoyable experience for myself, I learned a lot in 3d modeling and 3d printing skill, which upgrade my rc hobby to another level.
However the kit had some issues since this conversion it was my first attempt with 3d printing.
I decided to go through major upgrade to the kit for :
more simple assembly,
more strength and rigidity
as well as economically cheaper parts.
Watch how I managed to upgrade my own kit for far better grasshopper!
You can download 3d print files from below

Tamiya Inc. should hire you and start the Grasshopper 3 project :)
Great piece of engineering, congrats!!
thank you so much for visiting my channel! I am kinda too old to get a new job^^ though that would be a great adventure for me even at my imagination^^;;;;
I love the fact that you went for inboard motor. Well executed. Respect!
thank you for visiting my channel! returning to midship revealed far better after all! Also sub and liked your go-cart videos man they are exciting!
Just what I was looking for. Great reinvent. Thanks for sharing.
glad you like it! thanks!
Respect always 👍🏼
thank you^^
So awesome, can't wait for the slo-mo vid!
thank you! I will upload the video maybe end of this week^^ my daytime work for living is pressing me hard^^;;;;
Great work again. Nice that you keep on searching for perfection. Very clever designing around original axle and readily available parts for the TT platform.
thank you so much for visiting my channel! Yes! reusing the axle was my most satisfying part in this whole upgrade process^^
Bravo! Nicely designed 3D printed parts to accommodate the cost effective metal parts for this classic grasshopper. 👍
thank you so much for your interest!
Hi there and a super upgrade and some really impressive CAD work to 3D print the new components. Nicely done. Take care and best wishes 😉😊😉
thank you John always for visiting my channel and interest in my work!
Awesome idea and perfectly executed 🙌🏻👍🏻 Looks like it handles really well. Very cool Grasshopper
thank you! and yes by returning to midship layout, it has the good proportion of OG hopper, and even better with the trailing arm suspension^^
Wow that is amazing customized 3d print parts.
thank you always for your interest!
That is excellent!
I just put together a grasshopper with yout front wishbones and rear hornet conversion kit a couple of days ago, i wanted to do the previous trailing arm upgrade but didnt because, as you note in the vid, it is quite expensive.
Looking forward to being able to start printing this version and upgrading my Grasshopper, going to order the parts needed so they will hopefully already be here when you release the files :)
thank you so much for interest in my work! and additional appreciation for downloading my previous design. I am sorry the design was not perfect I really think after a rough terrain test, this new version is far better then previous version. I will update when file is uploaded soon!
@@HumbleVintageRC No need to apologize, im very thankful for your work!
I saw the two shorts you put out, the landing after hitting that rock was really solid, no rebound at all :D
I just put up a couple of makes of your designs ive printed over on cults :)
영상도 잘보고 가유😊
ㅎㅎ 항상 고마워요~~^^
I really enjoy your work and ideas.
thank you so much! your feedback is really helping me^^
I always enjoy your videos, excellent design, way better 👍
thank you so much, it is such a compliment!
That was really nice to watch! I love this possibility to make own solutions to things, although I never done any 3D printing myself, maybe someday, ha ha! I like that you used TT-02 parts, very common to find.
thank you! 3d printing is still not at level of standardized consumer product yet, but someday maybe! thank you always for your kind interest!
YOU'RE A GENIUS! WHAT A GREAT 💡...
many thanks!!!!
Great design. Are your parts printed in PLA or Nylon?
Hi thank you for visiting my channel! all my parts are home printed I use PLA+ basicall slightly better than pla^^
I really like this design, but I have a question after watching the video. How is the differential supported between the outdrives?
I didn't see the pin that normally goes through the center of the differential and between the original axles.
hi! thank you for visiting my channel!!! this design uses the same pin as stock hopper gearbox. I designed the diff gears with the hole for the pin^^ maybe that isnt clearly shown in the video? thanks for your feedback
thats a lot of work, i love it !!!
thank you! so much for visiting my channel! Yes it took me some weeks to get it designed, printed and assembled^^ I guess that gearbox in video was about version 0.8, I had printed the gearbox and arms over 5 times for validation and fine tuning^^ now I am pretty satisfied^^
so cool. Did you redesign everything in cad? Also, why not use brass inserts instead of screwing directly into pla?
thank you! my latest design update uses bolt and nuts for joining gearbox. Yes screwing into pla directly is not so good in terms of durability and maintenance. New design reflected that. Thank you for your comment!
found it thank you
files for grasshopper 1 and 2 is different, the link I gave you in my previous answer was for GH2. good luck!
@@HumbleVintageRC uh oh I have gh1
WOW!!.. That is awesome. WOuld you be willing to print and sell a complete set ?
thank you for visiting my channel!, well, I upload all my design files in thingiverse but right now its being delayed....will upload soon^^
I want to try this rear suspension, but I am sure producing the custom diff gear will be my stumbling block. Any suggestions on an economical way to metal print (or have printed) the diff gear?
hi! thank you for your interest in my mods. first, metal printing is pretty expensive as you addressed. my spent for metal printing was about 50 usd per set (2). you can choose to cut the stock axle and attach appropriate drive hub (such as kyosho optima’s). I used this method before I entered 3d printing era.
I suggest to print the diff gear in petg or pla+ this will endure more than 5pack runs with stock 540 motor run. If you want to run more you can simply replace the diff gear. Sorry for my limit in this design.
Wow! Super cool!! I wish I had the patience for learning and working with CAD design I have done a few very simple things and have tried other more complex items and I get so frustrated I end up tossing the idea! Great job on the engineering and design! If it was in black it would look factory!!! Are you planning on selling the files? I would love to print one and try it out! Very good job!!!
Hi! enormous thanks for interest in my work! The frustration that you encountered is exactly what I experienced in first few months, almost the whole year after I started 3d printing...all was headache and waste of print filaments....but I am sure your efforts will pay-off soon! I am now really a great supporter of 3d printing, take your time and be patient you will catch up soon! I don't sell my design files, I will upload it in thingiverse, just that I am right now too busy, I should be able to upload the files maybe this upcoming weekend^^
@@HumbleVintageRC Thanks for the encouragement! Thank you as well for sharing the files I am really interested in trying it out!!! You should call it the hopping hornet!!
super mechanic❗️
thank you! overwhelming compliment^^;;;
Amazing !!! where find stl files to try it ? I've a grasshopper race of the end of june and i Will be very happy to test it !
Thank you! file is not yet uploaded, I am way to busy to finalize and fine tune^^ but sure it will be available before your race!
@@HumbleVintageRC Just mounted, All printed with PLA. Hope enough stronger for the pinions. Now it's to find time to test it ! ;)
Hi there, this us really amazing work. I am trying to do this with my son's grasshopper and we are almost done, but have run into an issue. I purchased (I think) the exact same dog bone set as you. However the shaft of the axle isn't long enough to go all the way through the grasshopper wheels. It is only 12mm from the end of the threads to the pin hole, where standard grasshopper axles are 24mm. Did I just buy the wrong set or did you do something special to attach your wheels? Hope I didn't buy the wrong thing 😢
thank you so much for your feedback. I think you bought the right axle just that you need to print the wheel. those wheels are part of the work. or you can use optional extension hex adaptors to use normal hex adaptor wheels.
this limit is the reason I am working on next version of this trailing arm kit with new design and parts. though that older design works well kif you can print the wheels. sorry for the confusion^^;;;
can you check out this video for the next version. though its not finalized yet, this may give you some better idea

No problem, I didn't realize I needed to print different wheels too! That's super helpful, I should be able to figure that out no problem! This has been a super fun project to do with my son and you have done amazing work here. Thank-you so much 🙏
🤩👍💥💯😃👌👏☝🤩
thank you Ron^^
