Leaving the RC scene in the early 90's as a teenager, and starting it again in my 40's with my daughter, it's super interesting to learn what happened to all these companies in the industry over the years I was gone.
RIP Ofna bruh.
-Big front bumpers to no bumpers
-Mechanical speed controllers to Electronic speed controllers
-gear covers to exposed transmissions
-NiCad to NiMH to LiPo
-Brushed motors to brushless
-Aluminum to graphite and back to aluminum
-spacer shock collars to threaded shocks
-sleek car bodies to cab-forward bodies
Kinwald had a "undefeated season" in 1997 winning both the ROAR and NORRCA Nationals, the Reedy Race, and every 2wd mod race he entered capping it off with that win at the IFMAR worlds
Kinwald sounds like the GOAT
@@RoachRC Masami is the GOAT IMO(I don't think anyone will be able to touch his 14 world titles across so many disciplines),but BK definitely is in the conversation for best American RC racer ever
Awesome video! Loved Al Losi, Lucero, Peralta sk8ing back in the day. Now I'm old and LOVE LOSI rc cars at my local track.
"And a Hydra-Drive, whatever that is." - The Hydra Drive was a fluid dynamic slipper clutch. There were some other brands that made similar systems for both Losi and AE cars.
Think of how a slipper works, you have the spur gear being divorced from the transmission layshaft, and only transmitting power through the clutch pads. The Hydra-Drive works in the same way, only instead of a friction pressure clutch, it used a dynamic fluid coupling. Like a torque converter on an automatic transmission.
In the XX, the drive layout was pretty straightforward. The spur gear was lose on the layshaft, and keyed into the outer housing of the Hydra-Drive. Which was two clamshell halves with a series of radial fins on the inside. Looking kind of like a bicycle wheel inside. The outer housing which was spun by the spur gear, rode on an inner impeller which was keyed into the layshaft, just like the plates of a slipper clutch.
When you applied throttle through spur, it would spin the outer case of the Hydra-Drive, at which point the internal fluid (similar to diff fluid we use now in gear diffs) would dynamically fluid couple with the impeller, which would in turn drive the layshaft on the transmission input.
There was a single small friction disk on the back side of the spur gear, and you could adjust the engagement point of the Hydra-Drive by tightening down the adjustment spring.
Most of the team guys ended up running the Hydra-Drive eliminator included with the kit, that basically turned it into a standard friction slipper clutch. Primarily for feel, by reducing the mass of the Hydra-Drive from the drivetrain. And the few that did occasionally run the Hydra-Drive would use the longer and stronger clamping slipper spring, to tighten the engagement point of the Hydra-Drive to where it only ever came in at extreme full throttle.
The primary benefits of the Hydra-Drive was to really smooth out the power delivery on blown out, loamy dirt tracks, which were very common conditions at many of the bigger outdoor races at the time. It would greatly improve traction on starts by softening the wheel speed increase on starts, and also help to reduce the skipping and wagging that was common on rear motor cars. By using the inertia of the drive like a flywheel, along with it's ability to soak up wheel speed differences from bouncing a wheel off the ground, it would help the car maintain on throttle speed, and not get into the violent tank slappers that would happen on rutted tracks. See a lot of Masamis cars in this time period to see what I mean.
As slipper designs improved, and the quest for lighter weight drivetrains became more desirable, the Hydra-Drive and it's handful of similar designs, all went the way of the dodo, and where quickly killed off, never to be seen again. That said, I am surprised that in the current day and age of instant torque brushless motors, that we haven't seen a resurgence of a Hydra-Drive like device over the standard slipper clutch. Especially in 4WD where fluid filled gear diffs are the norm, and some form of fluid coupling at the drive input, combined with a fluid filled gear diff, would seem to make a lot of sense.
Here is a cool video about the Hydra-Drive, and one of the other viscous coupling solutions.

Thanks for letting me know.
bro can I use this for my essay project lmao
@@RoachRC Gene Husting said in an interview that Associated actually raced hydradrives on their cars at the 1993 World Champs. So a pretty important piece of off-road history!
Very good explination and history of the HD. I never did run one back in the day, and it didnt seem to have a big advantage on the local tracks, but I always thought it was an interesting concept. I happen to have one brand new in the package, and some rebuild kits. And no they are not leaving my hands.
Well done on both videos I raced a JRX2 Pro and a RC 10 1990-1993 I enjoyed the flashback and the History Thank you !
I wish I still had my Losi LXT. Got it at 13 in 1993 and that R/C car did so much for my mechanical knowledge. 13 years old and built the kit. Things have changed with all this RTR. I sound like an old man
I had no clue that variflex was a Losi product. I had a sweet hot pink variflex skateboard back in the 80’s
Great vid! Losi actually started importing the Yokomo C4 about the same time as the JRX2 came out. Jack Johnson was a driver for them and raced locally here in Vegas at Circus Hobbies. He raced his prototype JRX2s for years before it actually came out in 1988 and raced the C4 in 4whl until shortly after the JRX2 came out, then Losi wasn't importing them and Jack had switched to Kyosho for 4whl. Within a few months Team Associated began importing the YZ-10, read into that what you will lol And because there has to be at lease one in every comment section...the JRX-Pro SE didn't have the same molded chassis as the Junior 2. The Junior 2 chassis had provisions for the 5 link while the Pro SE chassis didn't and had a narrower body because of this. Also, the Pro SE had an extra set of holes for the rear suspension and transmission since the chassis was shared with the LXT stadium truck which ran a longer wheelbase. The XX-4 weak spots were the front shock tower (which would pretty much break every time it flipped on the track, at least until the revised tower came out) and the front bulkhead. 4 wheels BITD weren't the most robust vehicles so you pretty much had to hold your breath every time you got out of shape in midair 😆
XX-4 front caster blocks were another really weak point on that car. Mine was a rocket, but if you tagged any corner it was a DNF.
Found you like 2 hours ago instantly subbed.... You're legit too good at this thanks for the content keep it up
I personally like Losi and TLR products. I have a Losi Ten SCTE 1.0, 22sct 1.0 and 22 2.0. They perform well on the track, and I have lots of fun racing them.
Great video! Awesome coverage of RC racing history. Well done my man!
Super cool video! I didn’t know any of the backstory to TLR. I definitely learned a lot. Glad you are back and hope all is well.
Awesome history on the Losi brand man! Loved it!!
It's good to see you back. Have missed seeing stuff from you.
Great work. Keep em coming!
Great video bro!
Great video as always from your channel. Great research on this one and use of old clips
Glad to see another video great work keep it up!
Excellent video
Awesome video man
I grew up going to the Ranch Pit Shop in Pomona Ca. It closed in the late 90s or early 2000s as i remember.
Nice videos and great soundtrack. Subscribed 🙃
I've been R/C car racing since 1986 and these videos (AE/Losi) bring back a lot of good memories. Thanks. Those were some great days of racing.
Glad you enjoyed it man.
Back when off-road racing actually meant using a dirt track.
Another great video. Be fantastic to see some 10th touring car history ones as well and how that has changed over the years
Cool video i finally had time to chill out and watch it!
Glad you liked it😄
You do fantastic films, keep it going Sir.
great video
Rest in peace Brian Kinwald.
The Hydra Drive was a viscous coupling that gradually put power to the wheels so you didn't spin out. It used fluid similar to shock fluid
I still have my JRX-T and RC10 from the early 90’s. I’m starting to get interested to get back into the RC scene. Specifically 1/10 oval and off-road
The Hydra drive was a slipper clutch but rather than plates it was close to what you get in a road car with a fluid clutch. Was very good on low grip tracks like pure dirt before blue groove clay was a thing.
I believe the JRX2 finished fourth at the 1989 IFMAR Worlds, finishing behind the Associated RC10GX Stealth Prototype.
Great video! Liked and subscribed.
Can u do Kyosho next?
Team Associated had their origins in slot car racing;
Team Losi had their origins in skateboarding - and in Team Associated.
Great video. The buggy shown at 13:25 is a prototype buggy raced at 2005 Ifmar based on the JRX-S touring car. Looking at it now, it reminds me of the new Serpent SRX4 Gen 3 4wd buggy...
Great videos, thanks! I'd be interested in a video about classes, and which were most popular when.
7:20 the double x was an almost clean sheet design from the JRXpro SE. The only thing it really had in common was shock bore diameter and bearing sizes in the rear. You must be thinking of the LXT, which had many parts in common with the Pro SE
Really interesting stuff. Would love to hear about more classes too, like Gas Truck, which I never got to experience because it wasn't popular here, Touring Car, which I never heard anything from Losi about and 8th scale where they were quite innovative in the beginning and then somehow disappeared from my local market while apparently still booming in the US.
Also, little but important thing: AE kits are made in Taiwan (not China) and current Losi kits are made there too (not sure about older ones though).
I think Losi cars were manufactured in China for a short while early on. The fact that they're now in Taiwan is pretty good.
I had a JRX2 good times!
I think that many JRX2 prototypes were converted to dirt oval race cars, and the JRX2 was strongly associated with dirt oval racing early on. One magazine actually made the mistake of calling the JRX2 a dirt oval car. Later on it was officially released as an off road buggy.
I used to run my gold pan at the ranch;)
Now do a vid on how Gil started Helion & Arma.
Still have my losi jrt and xxt cr also xxxnt and a few rc 10 buggys
Hydra drive was a viscous fluid coupling slipper clutch. That usually leaked all the fucking time and had a lot of rotational mass.
So on the 1/10 acale market i agree Losi didnt do much between 03 and 2011 but on the 1/8th scale racing market they dominated it with the eight and 2.0 version
Hi nice short video.
The picture shown at 13:26 is not the 22-4.
It is a prototype Offroad car based on the JRX on-road drive train. It never made it to production.
The 22-4 is quite different from the picture shown.
My JRX2 instruction manual was lousy, but it was a great car. The Tamiya manuals were much better.
If you don't know what a Losi Hydra Drive is , you sir need to slap yourself across the face ( twice ) and beg forgiveness from the Losi die hard fans !
Nice vid , sound comes across a little muted and a little fast - keep up the good work :)
I would like you to do a history lesson on the races Tamiya and kyosho during these time because they have one races in the past against losi and associated.
Tamiya Frog was way before the JRX2.
RIP Brian Kinwald
Great vid.
You sound a lot like Sam Harris.
It was called the Ranch Pit Shop. Not Pit Stop
Xxx bk2 was amazing
I thought the Junior-2 and the Junior-T were stupid. They had no mechanical speed controllers. You had to get expensive ESCs for both of them! The Kyosho Ultima II still came with a low-cost mechanical speed controller.
Ya but the ultima was garbage
@@gary19222 Which Ultima?
I would like the history of traxxes
I have to ask this did Avi allow you to use this footage from RC retro it's probably stupid question or you wouldn't have it here Hope you know them he certainly talked about me on this channel occasionally.
He did.
6:45 there is a sample text.
Should be fixed now
@@RoachRC oh good. Good video by the way and I love the vibe of your vids.
@@threeis3451 Thanks man
As a 90s kid Losi and Associated were the best. Traxxis made toy quality junk.
Not a single mention of the on road stuff like the jrsx and the type r.
Much like the associated history video. Most of the onroad history is buried and seemingly intentionally so.
Team losing. Discontinuing parts 2 days after they come out with a new car
Eh
just for everyone DO NOT BUY LOSI HIGHROLLER!
Losi's for racing, not high rolling lol
