Tamiya Grasshopper upgrades. Hopper to Hornet
Вставка

- Thought this would be awesome to try. Roll through all the parts that made the Tamiya Hornet different from the Grasshopper and see how each effected the chassis. I hope you all enjoy these little videos. Been great spending time with the kids making them! Please like and subscribe and be sure to share (my daughter says I must say that..lol) if you want to see more. Huge thanks to all the positive folks commenting. Please let me know if there is something you would like to see (vintage rc) and I will see if I can put it together.
i just bought new grasshopper fo us50, this is my first tamiya rc
Great car. Enjoy my friend.
Fascinating outcome 🙂👍🏻
You need to upgrade the front tyres as you have the rear, makes the world of difference. I found the best combo for the Grasshopper is front wheels and tyres from The Fox and rear wheels and tyres from Hotshot 2 (including adapter/spacer for different offset. It transforms the wheel base of the car and helps stabilize that weight back end. Pins it down nicely. Also think about a few grams of plasticine in the nose for ballast against the rear. May seem mad adding weight, but it's just enough to shift the F/R bias in corners, now that your centre of gravity is lower from the earlier weight savings (shell). Great video!
been enjoying your content and am taken back 40 years to the heyday of early rc! big shout out to your daughter who has done an exceptional job capturing all this great footage! the dream has always been to play but also to see the cars in action and taking the bumps and jumps .. it's like you heard my wish from 4 decades ago. so good!
Thanks so much my friend.
It definitely gives us something fun to do together. Driving these old cars brings me right back! Appreciate it!
That was really amazing video and comparison!! Absolutely loved that!!! Thanks so much!
Cool video 👍
Thanks so much!
That's a neat backyard track. Plenty of area for spectators (neighborhood kids).
Down the street kid got a Slash for Christmas. He is SUPER excited to get it on the track....Should be a blast watching him learn to drive his 1st R/C on his 1st "track".
THANK YOU sooo mich! I like hopper style / design but want performance '))
This was the most fun as a kid to uppgrade the cars between races and practice ☺️ new shocks and wheels.. lots of fun 😄👍 great video and camera work ☺️💕
Got to love the upgrades and results. Still remember strapping in a modified motor for the 1st time!
Thanks so much for the comment and view. We appreciate it!
Great video!
Very cool video… thank you so much for sharing.
Thanks for the view and nice comment! Appreciate it.
Great job, lots of effort not gone unoticed
Thanks so much!
Nice job with the track layout
Thank you.
I would liked to have seen if just the tyres alone with no the changes would make a difference. I also often wondered of its possible to fit the talker gearing onto the little motor. Might rake all day to get up to full speed.
Great video.
Cool vid, props to the film crew:^)
the grasshop' is the best...beautifful with that sandbuggy body really fun with a 540 or bigger,not efficient but fun! regards from france! :)
Really great great video, great content and filmed on a phone!!!!
Thats an awesome track you have there. I was surprised that with more horsepower it pulled the same numbers. I also realized that with the bigger motor you got more air tome and air time kills lap time. Your daughter is a great filmographer if thats a word. Lol. I see her having a great future filming motorsports events
All about the weight and track size imo. Given proper room to air it out...it would be no contest.
Nice video
I had a lancia 037 my Freind had the grasshopper
Both had 380 motors total fun
Also nice xmas clip 👍😀
Had a Lancia as well (unfortunately sold it...). We are having a blast making these. Thanks for watching!
We should go to the website to Tamiya base they have all past and present motor specs. I have a dirt tuned motor on my grasshopper 17,000 RPM at 7.2 v I run it with a 7.4 v with 50c rating.
Brilliant idea for a video. I thought I’d watched all your videos, how did I miss this?! Awesome.
Thanks so much!
Was told the dark header screen is a little off putting. Might need to update that a bit.
This was a super fun one to do.
Should do another version on the new track.
Really interesting. Power brings its own problems. Any weakness in the chassis will show up with more torque. You can hear the under-damped hop under acceleration with the RS540. I think Tamiya's engineers knew what they were doing mating the 380 with the 'hopper.
I agree 100%. Going to re visit this a bit on the new track.
What a great effort you put into this video. The plot-twist of losing time with the 540 motor was surprising, but its understandable from the video showing the traction difficulties. I have seen some video where lead ballast has been added to the chassis of the Hornet to improve the handling.
Thank you so much. It's greatly appreciated. 100% a Power to traction available issue once you strap in the big block. Working on one with some suspension mods. Hopefully I can get it posted this season.
Awesome vids mate 👌
Thanks so much! Appreciate the view/comment.
Thanks for the detailed analysis.
I was about to build a Grasshopper with a silver can 540. I'll be installing a Sport Tuned 370 instead.
Cheers.
I have one here for mine as well. I still need to figure out how to get a pinion for it...but I assume it should not be that difficult. Thanks for the view and comment!
Great video. Footage was great. Big up your daughter. Now I am interested to know how it would go if you did the motor swop first.
Oh god..the plastic shocks were just awful ..lol.
YES put some of front rubbertube 1cm with grease in the back zylinder over the screw you have a little damping :)
You should checked it with the hard body too with the pin type tires on the back.
Awesome video, my hopper has the slotted front pivot too (along with ball bearings) but still on the pogo stick friction shocks. Had to glue the tops on otherwise the shocks would fall apart lol. Got a 27t stock motor in it and It don't need nothing more 😂. As much as I understand the Hornet is a overall better car with these upgrades, i just prefer the look of the Grasshopper body shell more
Big fan of the Hopper body as well.
Think it looks cooler.
Great video guys.
I always wondered what Grasshopper mods were worth messing with.
Thanks so much.
Was really fun to do this one!
i have Tamiya Hornet already and got another one cheap, i thought i made a mistake not going for a grass hopper. your video game me the idea of putting grass hopper body on a hornet and have an upgraded grass hopper. thanks
Awesome! All good either way. These cars are beyond fun to drive!
You should do all these differences in reverse too.
Great work! THANK to your daughter roo! I like how you think of things :) sorry for my englisch greetings from germany. Could you do three laps AND eleminate slowest? PLEASE ONE try with softer rear springs AND grasshopper body =}}
Thanks so much for the comments! Getting cold/rainy and dark very early now. It's making it tough to get things filmed (been trying to get the Sand Scorcher video done for three weeks). If I get some time after that one...I am always open to new ideas!
Meaning with all the changes.
GH seemed a lot more peppy with the hornet tires
I think they absorb some of the shock for sure. Definitely more grip on hand.
I put a Sport Tuned 540 motor in my Grasshopper with a small LiPo and yeah, it was better before with the 380.
I have a Spektrum radio from my Granite on it, which is good because it has a 50-75-100% throttle switch on it, I rarely put it above 75 because the car can't handle that speed without randomly flipping over, especially with the Hornet tires on it.
Could you update the description with the suspension parts you used?
That's a lot of power for sure for a little buggy. Might do a hopped up hornet video this year.
@Vintage Backyard RC, did you ever post …
1. Where to get the Hornet Shocks? is it a particular hop up part #? That seems like the one upgrade that was really worth it on its own (or maybe I made the wrong conclusion from the video?)
2. What lap counting system are you using there? Do you like it and have you compared to any others?
I had the shocks on hand...because I have just come across so many cheap Hornets over the years and have a hard time saying no when I see one for sale...lol . If you look on Ebay people part out re-re shocks for very cheap. No particular part number that I am aware of though..
I use the Orion lap counter system. It's very old school but still works great. Have not tried anything else because this still seems to work great.
Thanks for the questions! Sorry for the delayed response.
After a lot a research, I discovered that the Tamiya CVA Short Shocks are a perfect fit for the GH. I just finished my build this week and started looking for suspension upgrades immediately.
Loved it. You need more laps per test though, sample size of two is statistically too small. 5 min, maybe 10, but the more the better really! 15,30,50,100! 😁
Think we did 3 and showed two on this one. Was still trying to balance out view length back then. We try and do 4 now.
@@VINTAGEBACKYARDRC You could do say 10 or 15 and jut show the constant ones. Too easy to muck up only a few laps in a row and then the average is screwed if you only do one good one. Or maybe you do 15 and take the fastest as best, or average the 3 fastest etc? Need that consistency to show real improvement and anomaly negation for off chart bard laps.
Awesome video! I’m currently looking at doing minimal upgrades to my Grasshopper. Are the oil shocks worth doing?
Yes. Might be better aftermarket options for sure.
you should have taken off the oil field dampers and use the friction dampers normally for it with the pivot rear end and see if there was a difference there too.
That is what is on my hopper. Makes it soo much better off road and on. It can lean in the corners making the front end work, however I had to glue the top of the friction dampers on as the extra movement meant the tops kept popping out
Do I need the tune up parts in order to build the car I got or do I not need them?
These cars run great right from the box. One hope from this video was to let people decide what they want to upgrade.
where;s the antenna don't you need that? it is a pain when it flips but can you still get good reception without mounting it up an antenna rod?
Modern 2.4 radio.
No need for an external rx antenna anymore.
It's wonderful!
Your friend with the grasshopper is the one dislike...
How to fix honey body on grasshopper?
To fit the Hornet body...you will need the front and rear mounts. Should be it my friend.
The slotted front pivot anyone know what part tree letter that is?
You need the D parts tree. I think it's #9005156.
@@VINTAGEBACKYARDRC thank you
'
both models are the same parts and different bodys...
but two motors are different sizes...
better use a 540 than 380
You should have left the grasshopper body on it you just made it a hornet 🐝 big deal. I wanted to see the grasshopper body with the 540 and oil shocks that would have been cool as the grasshopper in my opinion is better looking and I like the sand paddle tires . A little disappointed in this one. I like your videos but am such a fan of the grasshopper body... and tires..
I think you might like our 1st time attack video (coming soon).
Great video!
Thanks so much!
