This is the first of three races to determine the 1991 2WD Off Road World Champion. Masami Hirosaka, Rick Vehlow, and Kyle Reed were the cars to beat.
Location: Sterling Heights, Michigan
Vehicles: RC10 Stealth Car, Losi Double-X, Schumacher Cougar, Traxxas TRX-1

Awesome. Back when off-road was off-road. Love seeing them throw a roost up.

[@dronepro7316]

This was when r/c was still a great sport. More sense of a community, but still in nova and competitive. And a real off-road track that wasn’t super hard packed.

[@joecaca4136]

They need to bring back dirt tracks that have all the real features of OFF ROAD racing like this one! Watching this video further reinforces the nostalgia of reading rc car magazines that covered the IFMAR championships. Like others said, seeing roost being thrown is a must in off road racing. I wish they would get away from the high bite traction racing.

[@therctutor8100]

Now these are race tracks. Loose, loamy, unpredictable and “fast”. Anything can happen to anyone. Wish these types of tracks would make a comeback. These are the tracks that made people like Brian Kinwald (RIP) smarter and more adaptable. These are the tracks that made young guns think critically.

4 mins in.... "on him like white on rice...." oh how times have changed haha

[@davidhilton5414]

Haha like Larry Huffman that used to announce Supercross back in the 80s. “All over him like a Krishna at the airport” Baha 😂

I was into R/C pretty hard back then, hard to imagine its been that long since I went to watch this event.

[@Bormac073]

Liked. Subscribed. Great seeing the older IFMAR events on KZbin. Thank you.

[@markn2615]

Panasonic scr or sce sub-c cell batteries. 7.2v 6 cell or more likely 8.4v 7 cell packs. all these dudes had all the goodies. hand-wound custom motors, plus the 8.4v 7cell packs = pretty fast. it was the runtime that got 'em back in the old days. you could only maintain a charge for 4 or 5 minutes back then.

[@ctsd623]

7 cell packs weren't legal, it was 6 cells only for IFMAR and ROAR. And Sanyo made SCE (yellow) and SCR (red) cells, and the subsequent SCRC (black) cells that give the best of both worlds

[@davidhilton5414]

Is that dirt flyin, and lines developing that I see?! Not to mention the whoops!! So rad!

[@Silverexpress01]

From what I remember, that was a very nice track. I was 17, and saved up all my money for a Tamiya Grasshopper. Picked it up from Joe's Hobby Shop. I think. That was a fun summer and gas was still relatively cheap for the Cardoba.

[@RacerEckss]

I don't like to self promote but....Thumbs up to bring back roost!!!!

[@rustyATV]

Yes, looks like like mine. I believe Losi also introduced the Hydra-Drive at this race. I remember reading the article where the author noted the Losi cars went through the "Surfs Up" section smoother and straighter than the others, and they attributed it to that.

[@jaylestingi5418]

I had a feeling Losi introduced the Hydradrive at this race. It was plainly obvious that Kyle Reeds Losi went through the whoops way better than Masamis Stealth car. I has a BNIB Hudradrive with both light and heavy hydradrive fluid (gear diff oil) and was going to adapt it to my old 22 3.0 a few years back. Todays black CRC carpet "off road" tracks don't need it! I race on road now but love this era of RC

[@mattluszczak8095]

Best tracks. Fast open and flat out!

[@asepiwan1]

that was truly cool .... was that young Hirosaka-san?

Post up some old 1/8 offroad racing if you have!

What kind of batteries and motors were these guys using? I've been in the hobby quite awhile now myself, and remember Lipos coming out, and brushless motors coming in to play, and they were both past 1991, for consumer, regular guys like me, anyway. Did these guys get hands on goodies, cuz those cars sure look like they move out nicely for a brushed motor! I did notice the battery pack shot in the beginning, and that's no Lipo.

[@twopopsaqullu9721]

The batteries were 1500 milliamp sanyo cells but probably had 1800 actual milliamp because they were the best of the best saved for the top racers .

[@PeTroL420]

They used 540 sized brushed motors that were hand wound and they were in the 11 to 13 turn range. As far as the batteries, they were Sub-C sized but I believe they still used NiCads in 1991 and had 1800mah. I'm a little hazy about the batteries but what I do remember was that you wanted to get a set of Matched batteries if you wanted to be competitive. Matched batteries were batteries that were put in a machine that would charge the batteries at something like 5 amps but then then would discharge at 20 amps! This cycle was repeated a number of times and then the final time they did it, they printed a little label with the amount of time in seconds that it took to discharge that cell at 20 amps and then they would group the batteries in a set of six and those six batteries had similar discharge times. This was done so the voltage of each battery would drop at the same time so the effect you had was a car that would be going fast and then slow down to a crawl when the battery pack ran out of juice where Unmatched batteries would gradually lose voltage instead of a sharp drop because there are cells that are discharged before the other cells so the battery pack gradually loses voltage instead of dropping all at once. Also, the Matched batteries with the longest run times went for a lot of money.

[@robertturnip7850]

Yeah umm Lipos and Brushless motors were a long way away in 1991.

[@originalrcfun7368]

@@PeTroL420 Great write up☝️👍

[@originalrcfun7368]

@@robertturnip7850 Matched batteries was very good back then. When the lipos became aviable, the nimh batteries was low priority and was not of good quality. And has been ever since. The only "good" nimh batteries today is from Traxxas, Reedy, LRP / Nosram and Team Orion. A matched pack cost 80-90 bucks back then, when a ok basher pack cost 30-40,- After each run, you discharged each cell individually down to a spesific voltage. After charging the battery, they allso boosted the pack, with a bigger pack, to push in as much power as possible just before race start.

[@superbrit3845]

Looks a real tricky track to race on. Can see why Associated developed a one off RC10 for this track as it's mega bumpy.

[@RockItRC]

Awesome LOL classic!
