MX-4 FOREVER - A Very Special 4WD Buggy Designed and Built by Masaaki Hirosaka and Masami Hirosaka.

I am extremely fortunate to be able to add this rare and oh so very special buggy to my collection.
My video production skills are far from good, but I do hope I have done this buggy and more importantly, what it represents, justice. All stills in the opening slideshow are from Masami and Masaaki's Facebook pages. Links below.
Over twenty years in the making, the MX-4 FOREVER is the final piece of work by Champion Mechanic Masaaki Hirosaka and his son, The Legend, Masami Hirosaka. Designed and then built by hand, only 100 buggies have been produced. I am lucky to have number 41.
For a detailed build diary of the MX-4 Forever please see the Facebook pages of Masaaki and Masami Hirosaka.

Thank you for your posting.

[@KaiCityRC]

My sincere thanks to both you and Masaaki San for producing such a wonderful RC. ☺️

[@compsrx1]

Beautiful car. Love your introduction with heart warming music. Enjoy the Legend of legends in RC. Masami-San❤ KO.

[@KaiCityRC]

Thank you! 😊

[@MrSneakyGunz]

❤ You have a very special son. ❤ What an amazing gift... I certainly couldn't run that kit.

[@RCShiney]

It seems like such a shame that these cars that they worked so hard to produce will most likely never see the track, but if I had one, I don't think I could run it either. It's a work of art. It's special that your son got you this and seems fitting given that it was a father and son that made it. Congratulations David and thanks for sharing this wonderful video.

[@KaiCityRC]

I totally agree. These, indeed any RC was made to be driven. I try to drive everything I own, so I can honestly say I only have three shelf queens - cars that were built and never driven. Everything else gets used, though as my collection has grown the frequency of use has declined. This MX-4 is very special for so many reasons, so I don't think I could ever bring myself to run it. But never say never...

[@florabee9283]

I never thought I’d ask you not to run a car, but I am for this one!

[@16-BITFPV]

You wouldn't like me that's for sure LMAO I run everything, I even take new/old toys out of the package.

[@KaiCityRC]

Thank you! ☺️

[@wadeskelton7585]

It’s clear just how much you appreciate this car David and for that you deserve to be one of the lucky few - your love for the hobby comes through in every video you make brother congrats and thanks you 👍

[@KaiCityRC]

Thank you for the kind words and for taking the time to watch and comment. I am very fortunate to have gotten one. The RC hobby has been a life-long passion of mine and I'm lucky to have such an understanding family! 😊

[@BajaJeremy]

Congrats David! What an amazing gift and I’m so glad it came to you! Thank you for sharing with us

[@KaiCityRC]

Thanks for taking the time to watch and comment. You're right, it is an amazing gift. I am very lucky! ☺️

[@rcaficionado]

Wow, what an amazing gift from your son! Whatever you decide to do, enjoy it and always remember his generosity.

[@KaiCityRC]

Thank you! It certainly was a very special gift. I am very lucky. ☺️

[@MrNitro468]

Hats off to you sir! Keep it on the shelf where it belongs to admire. Whole lot of rc history there built by the best.

[@KaiCityRC]

Thank you!

[@AddamsPlayground]

Well your son just won the son of the year award for sure! LOL! What an incredible piece of RC history and I could never take it out and run it around. If it were a a Tamiya or Kyosho "limited edition" car then sure. It would be limited to thousands to tens of thousands of them. This one is exceptionally rare, hand built by the master himself and only 100 ever to be made. I would end up storing it in a safe!!! Of course it is yours so by all means, it is yours to do whatever with it. I am sure no matter what it is not going to be a decision made right away and just a thing of beauty to look at over and over again!

[@KaiCityRC]

Hi Addam, sorry for the delay in replying. I somehow missed your comment. 😅 I always try to run everything I build, even if it just lightly or once. But this is too special (for many reasons) to run. Perhaps in the future I may change my mind (never say never). But for now, I'm content to just admire it on the shelf...Well, at the moment it's back in the box. 😁

[@AddamsPlayground]

@@KaiCityRC I 100% understand! Definitely a very special one indeed!!

[@martianrc5516]

I love your channel, please never stop!

Thank you! ☺️ Truth be told I've been struggling to find the time and motivation to produce videos of late. and have so far only put out one video this year. 😔 Hhopefully I can find the time to produce more content soon.

Thank you for this video. Such a beautiful buggy, especially with the backstory about the creators. Also it's so nice that your son gave you this treasure! ❤

[@owenbuttle3304]

Incredible David. I’m so pleased you have one of these and I can see you will cherish and appreciate it for a long time. I couldn’t bring myself to run it… ok maybe briefly in my living room!

[@KaiCityRC]

Thank you! Perhaps one day I will run it. But for now, I'm content to admire it on the shelf. 😊

[@stephenpheonix6549]

Wow you are so lucky and your son is so kind and thoughtful. What an amazing buggy and way ahead of its time. It would have been so fast if they made it to the worlds. Thanks for sharing your unboxing. 👍🏼💯🇦🇺

[@KaiCityRC]

Thank you for taking the time to watch and comment. I am indeed very lucky to have one! I have no doubts the MX-4 would have done very well if it raced in the 2001 Championship. 👍

[@agevan6735]

Wonderful! Thanks for sharing!

[@KaiCityRC]

[@claytonfarlow76]

What a fantastic video, you really did the car justice. Anyone can see how much the car means to you from your expression and how you talk about it! You also must have been one of the first to receive their cars, so to get a video out so quickly is a real treat, thank you. Difficult to know what to do with the car regarding driving it or not. Perhaps the answer is to have 2 cars!

[@KaiCityRC]

Thank you for taking the time to comment. ☺️ Being in Japan, relatively close to where they were built, meant I received mine quite quickly. Fortunately it arrived on a Saturday, so I had the time to record, edit and upload the video on the same day. Several other Japanese buyers have received theirs too. Some of whom have installed electronics and are preparing to run them! Funny you should mention having two. Even if I could afford it, I don't think I could buy two. Personally, it wouldn't feel right to take two of such a limited number and deprive another fan of the pleasure of owning one...

[@claytonfarlow76]

That’s a very valid point regarding having two cars. I can’t imagine it would’ve been that easy to get two anyway, even if you had the means to do so. I keep searching for ‘MX-4 Forever’ on KZbin looking for new videos now they’re out in the wild. There is now a short video going around of someone driving one.

[@KaiCityRC]

@@claytonfarlow76 One Japanese owner, "mrc matrix racing club" on Instagram has just completed a shakedown run. There's a short video on their feed.👍

[@jemster38]

You're a lucky guy! If it was me I probably wouldn't run it. It's a collectors' item for sure.

[@KaiCityRC]

Thank you! ☺️ The story and people behind this car are what make it so special.

[@coygtrc]

It's absolutely beautiful, David. Some years ago, I would have bought it immediately. Still I would have preferred to have the choice of building, knowing that the engineering was anyway close to perfect. I would totally understand that you do not run this car. Kudos to your son, that's an incredible gift and thank you for showing it to us 👏🤝

[@KaiCityRC]

Thank you for taking the time to comment. I also prefer to build kits myself, but this is an exception. For me, the fact that the MX4 was built by the Hirosakas adds a great deal to its value. ☺️

[@laserbeam1620]

Wow what an incredible piece of machinery. I'm jealous!!

[@KaiCityRC]

Thank you. I'm very fortunate to have one in my collection. ☺️

[@n22pdf]

Wow this is amazing David.. incredible.. a beautiful buggy.. you must feel honoured to own this car.. wow.. Pete

[@KaiCityRC]

I feel very lucky to have one in my possession. Something I never thought possible. The history, how it was made and the people behind this machine are what make this so special. Thank you for watching and for your continued support. ☺️

[@theoagrc]

Amazing David!! Looks stunning and what a special gift from your son. I am not sure I would be able to run that and I run everything 😁

[@KaiCityRC]

Thanks Craig! 😊 Like you I run (almost) everything. But this is something very special... For now, I will admire it on the shelf. 😁

[@hinnmanfamily]

It'd be awesome to have some running videos from Masami, I can't imagine anyone else running one of these works of art.

[@KaiCityRC]

There are some short videos of it running on various tracks. I also have some footage of it doing a few laps at the GFCC on the day it was first announced.

[@nc6766]

The very definition of a masterpiece.

[@KotaroChannel]

A great RC buggy. From Japan

[@lo2713]

Such a wonderfull looking buggy, a good friend of mine is getting one, so i’ll be having a really good look at one soon. And another will be hitting the tracks, yes thats right. He’s going to run it. And hopefully i will be there to see it on track for the 1st time. Great presentation on this video 👌

[@KaiCityRC]

That's great! I got to see Masami drive the prototype at Tsukuba on the day it was first announced and it was quite something.! He didn't hold back at all. 😲 If I did run mine, ( a big IF) I don't think I'd be brave enough to venture onto a dirt track, so getting to see one putting down some laps is going to be fantastic! You'll definitely want to get some footage of that. Thank you for taking the time to watch and comment! 😊

[@lo2713]

@@KaiCityRC thank you for posting it, one car i would love to have been able to get. But way out of my price range 😭

[@travymoto1]

What a car. Wow

[@DivineInt]

It's such a beautiful car and I can understand why people wouldn't run them but surely it deserves some laps on a track, it's what it was designed for after all.

[@KaiCityRC]

I've had a lot of time to decide whether to run it or not. But no closer to making my mind up! I'm not one for shell queens and firmly believe that RC's were made to be run. But this one is different...

[@rccarloverluxembourg718]

glad for you, I just asked myself which one I would like to have instead of this and my easy answer is the world champion car I admired in my rc magazines for years :-)

[@KaiCityRC]

Thanks. ☺️ Owning the World Champion car would be very special!

[@marknethercott7024]

Wow! Absolutely stunning buggy and such an incredible history behind it too. Maybe save it for a special occasion like running it with Masami himself? Thanks for sharing!

[@KaiCityRC]

Perhaps one day the MX-4's will re-unite for a run with the Legend himself. It will be interesting to see what machine Masami chooses to run at next year's GFCC. 😊

[@tomconnors8165]

A beautiful car. The story of a car that could not drive the event it was made for should not wrap up with a bunch of cars on shelves. Don't abuse it, but let it be one of the few that got a chance. It will still look just as good when you put it back, and you will have given a bird its wings back. Whatever you choose, thanks for the video of it.

[@KaiCityRC]

[@Glocktologist]

There’s something to be said about raising a son who gives his father presents - of the kind that the parent couldn’t (comfortably) afford. And it’s not like your son can be that old since you’re barely middle-aged yourself. He has found success in life at a young age. The car looks phenomenal from an engineering standpoint, and it has an interesting history.

[@KaiCityRC]

Thank you for the kind words. ☺️ People often tell me I look quite young, though I personally don't see it when I look in the mirror each morning! 😁

Great video as per usual. Glad you got one of these. Appreciate your insights about the buggy (as well as all of your other buggies) and the pure racers that created it. It would be awesome to see a running video of it, but I can understand if you choose not to run it as well. That said, as Jerry Seinfeld has suggested on this topic, who are you saving the car for by not running it? Nice work!

[@KaiCityRC]

Thanks 👍

[@danjaz2000]

Im super happy for you. Thats how to do limited addition. In a way its like buying a Ferrari of the rc world. I think most will say dont drive it and they are probably right. But... you can buy parts...and we know if it's left on the shelf the tyres go bad. The belts go bad. The plastic gets brittle. Unless your saving it for someone else maybe you could enjoy driving it just once. But I dont blame you for keeping it perfect. It's only perfect once.

There original racecar just before 9/11 belongs in a museum, your car also belongs in a design museum I personally think you'll feel better one day if it does a few laps round a proper old school grass/dirt track no jumps, even the film would be a memory for you and your family I'm guessing it has ball diifs at least rear, remember Cecil Schumacher invented them .

If you want to run it but keep it perfect go to a vinyl wrap shop and they should have scrap pieces. I used some for my RC10 40th and it works great

Does this car have parts support? That should determine if it should be run or not.

It does. Purchasers are asked to contact RC Shop Hirosaka directly for parts and after sales support.

I can picture Gforce making a 4wd car to compliment Genova based on this car.

I think it is only a matter of time before we either see a Genova Mk. II or a 4WD machine from G Force. 🙂 What form a 4WD buggy would take is anyone's guess, but I'd imagine it would follow the Genova in being a retro inspired, predominantly plastic, but nevertheless very capable mid-tier machine.

I admit I considered getting one but this car is not a vintage, not a legend, not a former champion, not new, it's a semi-serialized old prototype... You shouldn't even get it out of the box. If it wasn't a gift, I'd tell you to sell it now because I'm afraid in two years, nobody will care for this car - no matter how limited it is
