A return for rear motor cars ?

[Buggyman]

Hi all, hope everyone is staying safe and well.
At our local club we have decided to have a rear motor class when racing can resume and I have got myself a car for this purpose. I find myself more eager to run this rather than my new associated b6.2 and I started wondering why. It seems that the thought of running a rear motor class appeals to alot of members and I personally feel even though they are certainly not as fast as the new breed of laydown cars they seem to have a more nostalgic charm to racers who have been racing for say 10 years of more. It's left me wondering if we will see manufacturers ever
start making rear motor cars again and maybe even developing them further if this class was ever to get popular. To maybe start this I ask if you have an opinion on this then I would love to hear it and maybe post pics of your rear motor rides if you have any. I'll post some of mine when I have painted it. Thanks all...

[fidspeed]

would be a wonderful return
problems I see are who currently makes a rear motor modern 2wd
schumacher still do a KD but instantly I'm at a loss if other manufacturers do ?
I hope I'm wrong do yokomo losi or AE still have a rear motor car ?
if that's the case were into running vintage stuff and spares can be hard to find
plus just sold my last b4::(
I have a topcat nib to build but it would be no match for a xx xxx or b3 b4

great thought at club level on old school grass only though :thumbsup:

The Schumacher kd is rearward mid motor. I was thinking motor out the back. At the moment it's all vintage or re release but you can get an old b4 or cougar kr for not alot these days and it's all for fun.

This is mine, I was hoping to give it a run this year outdoors but that’s not now going to happen:thumbdown:

We run vintage at YORCC, which by default means rear motor. Mostly Associated and Losi cars.
This is my B3 and I also have a B4.2 though the B4 is deemed too new as we use 2000 as a cut off for vintage.
I definitely find the B3 more fun to drive than my B6 and it works really well on the low grip gym floor.

[MHeadling]

I've built up 2 x B4's during lock down and intend to race them in the SE, 1066 club are going to do a 'Classic' meeting on grass so will be cool running the vintage and the rear motor cars there

I've seen a few races in the states where they run a rear motor class

Doubt we will see company's go this route but nice to see all the rear motor cars being brought back to life

Some pics of my b4.2. body courtesy of penguin RC.

[Yorkiebar]

The last made ones I can think of are the TLR 22, VBC Firebolt RM and the Yokomo BMax2. There's also the others like the Ansmann Mad Rat.

[jasonrcb]

We have been running a rear motor class in the midwest region for the past 6 months or more,the MAM series had it's own class for rear motor and both coventry and telford did seperate heats if the numbers were enough,it was really good close racing not to mention fun and regardless of a newer or vintage rear motor times were pretty close,at 1 of the kidderminster MAM rounds Tommy Hall qualified his b4.2 3rd overall in the normal 2wd class and only a few seconds off beating his own TQ,it wasn't a low quality field,bone dry track and 15yrs of development of cars to where they are now he got within a few seconds of TQ

[Chillout47]

Rear motor all day for me, and I also cannot wait for the cab forward body trend to die out as well - I absolutley hate the look of them, to the point that I won't race a modern car!! vintage is the future for me!

[c0sie]

Original "cab-forward".

Are you guys that are running the rear motor cars struggling to source parts at all?

[adey]

I will say I ordered the cab forward body for mine as it's the plus 8mm chassis and thought the rearward cab rear body from penguin wouldn't fit as it's the standard length. I have a read cab body off my old car and it can be made to fit easily as it seems so I will be ordering a rear cab from penguin as I think it will be better looking and more original. That said I am not sure if the b4.2 came with a cab forward body in the kit.

Funny this thread cropped up.

I purchased a Centro off ebay and unconverted it back into a B4. I'm more excited to run this than the latest 2WD I've recently finished building! It has all the period parts like brass bulkhead, alloy steering rack, uprated slipper etc.

It's been wired up since this photo, with the receiver stashed under the ESC platform. Can't wait to try it.

[Cobra]

This is the rear motor TRF201 ran at the MAM,s in the mid west

[Buggyman]

So who now is on eBay looking for a rear motor car or parts lol. That b4 looks real nice.

[johnboy]

I am selling some B4 parts all new in packet just listed in the sale section

[/tobys]

Would love to get a rear motor buggy again; ran the XX for years back in the day and on my return (10 yr lay-off) a used B4 and loved it. Availability is tricky though (I’ve been looking, admittedly not very hard, for about 6-12 months and not found anything suitable) and I would be concerned parts would be hard to get/expensive if I did get something?

[Buggyman]

What type of rest wing is that mate ?

Shame the B4 isn't old enough to run in vintage but if you're just looking for a rear motor car it's a very good chassis. Maybe a B5 if you can find one but I've not seen many.

[Danosborne6661]

It's Phat Bodies new rear wing :)

B4 was a game changer when it arrived around 2003, nearly every car was a B4 in 2wd. Only die hard XXX fans used their's

Still have my B4 Stealth from 2003 bought from Morley Models. Original Cyclone Esc and KO Servo. It's more like triggers broom tho, lol

[CHEVY]

Triggers broom is looking fit for work

[MHeadling]

My weapons for the rear motor class are ready, and hopefully a trip to the new Nemo dirt track :thumbsup:

[Dazzieboy]

The Kyosho RB6.6 came with all motor configurations in the box including rear motor. These parts will also fit the latest RB7 :thumbsup:

[HarlowS]

This bodes another question...... can a 10-15 year old car compete against the likes of the schumacher and kyosho cars of today that have kept an option of rear motor...... Will this become a fair match ??? :confused:

Correct me if i'm wrong, but not on high grip surfaces. Maybe closer in the wet. Be interesting to see but I even think dirt/low grip versions of mid cars would still lap faster. All depends on the driver too.

[HarlowS]

I was referring to the comparison of a 10-15 year old rear motor car versus a modern day rear motor car.

[revol]

I'd have thought they'd be pretty similar. The gearbox on my B3 really isn't that different to the B6 bar the obvious layout change. The internals are very much alike. Only thing i miss on the B3 is a gear diff.
What else has been a big change in 10-15 years? Big bore shocks? Tyres? All things that you could retro fit if you wanted to. Certainly the gearbox on a B3/4 can handle current brushless motors no problem, apart from the fact you'll wheelie every where on high grip!

[/tobys]

Agreed - I would have thought the suspension geometry is very similar and the B4 gearbox innards are robust (just no decent gear diff). I would think a B4.2 Or rear motored B5 would be very comparable to/competitive with those previously mentioned “modern” rear motor buggies.

[Big G]

All B5’s are rear motor Toby. Otherwise they would be B5M’s

[stuey]

I have been considering converting my X-6 squared back to a B4 as I am more likely to run it that way. I have a B6.1 so the mid motor car is covered. Nothing wrong with the X-6, just nowhere relevant to race it these days.

[Buggyman]

This thread is popular. Lol.
I think even if rear motor cars are not really a car for manufacturers to persue......they live are still going strong in the minds of racers.

[charlesk]

There's just something rewarding in driving a car that can and need to be hustled to go fast.
Which is one of the reasons rear motor cars are enjoyable.
The other one obviously being nostalgia.
Saying that I love driving my B3 runner and building a nice spec B5 to be able to continue to run RM for fun.

I race both a B6D and a B3 at York on a mix of carpet and low grip gym floor and the B3 is by far the most fun to drive, though not as quick over all as the newer cars.
I might get my B4 out when we finally get racing and see if I can get it handling as well as the B3.

[Buggyman]

To offer another spin on the rear motor thing.. anyone think a rear motor could ever be made faster than a mid motor on high grip. Bearing in mind the new Porsche 911 gt2 has just set a ridiculous record time around the famous German track...ahem,, in front of the Ferraris and McLaren's with its engine at the back. I know it's a totally different kettle of fish but principally it's a car with the heavy bit in the wrong place and it raised a question in my mind. Could a rear motor car be made competitive and if so...how.
Obviously there will be people shouting no way but it's all for fun.

[charlesk]

I'm afraid the gt2 rs has the motor so far forward that it's not actually a rear motor car, weight balance 39/61 is the territory of mid engine...
So as much as I like driving rear motor rc, mid motor will be quicker on anything but v.low grip.

[Buggyman]

Your spoiling the fun here mate. You know that don't you.....lol

[revol]

You'll never overcome the basic physics of having that much weight out back beyond the rear axle. You could add weight to bring the balance further forward but then you end up with a heavy car. As you turn in the effect of having the mass at the rear on high grip is obvious, the car just wants to sit down on the rear and you end up loosing what little front grip you did have. On successive left/right sections its even more amplified.
Still a good low grip set up though.

[Buggyman]

I don't know if anyone would remember but the Durango dex210 had the ability to run either 3 or 4 gears in rear motor guise. What difference would the 4 gear make in rear motor ?.

[charlesk]

Your spoiling the fun here mate. You know that don't you.....lol

Part of the fun is driving something you know is compromised 😂
Love driving rear motor, but I'm also aware that I'm faster with my 6.2 everywhere.

[Kev B]

think the 3 or 4 gear was all about motor rotation on and off the power to generate grip. Bit like when you watch a dragster leave the line and twist with the motor rotation.

I think the fun part about rear motor cars is the calm predictive chilled driving style. I find them easier to drive on the limits compared to modern stuff and although not as fast just rewarding

[daz75]

Before they went EOS and used the slippy floor I got my XX into the a final against the modern cars. Nowhere near as fast on EOS tho

[Aire valley]

And there you have it.....carpet tracks, the ruination of fun driving..!.😉

[smokes]

Being running my rc10 worlds rerelease with 13.5 at a1 racing, itc ould hold off the B6,2 on most of the corners except a downhill hairpin it would roll unless I braked. The shocks are leaking air.

I am Thinking of putting a old 7.5t in it to see what happens.


Note a1 racing is low grip astro.



Just need new o-rings to seal the shocks up and it should be good to go.

[pbiggy]

Hey all, been floating around oople for a few years, quietly gathering handy info on various things.

During lockdown, I came back to the idea of racing and 2wd buggies and duly rocked up to the NORA track with my badly setup mardave cobra on mardave spikes all round, only a loose slipper in the final kept me from the glory of D last place, beaten by an 8 year old driving a kf!

Anyway, I bought 2 new to me cars, same chassis, 3 or 4 gear standup MR or RR, some weird ass 10mm hexes at the front meant steering was merely a wish when power was applied with the kit ribs(!) but day finished much to the delight of the cheering crowds, maybe it was laughter but it's all a bit of a haze after an evening of strong tea to celebrate.

This week, I bought a veg steamer, threw the oe wheels in for an hour kit set the geometry and peeled off the ribs and inserts no problem, glued in some green cut staggers and it was like a different car, actually had steering at all parts of the corner with just a touch of understeer on the corners leading onto longer straights.

Anyway, nobody has mentioned the hobao hyper h2 so heres my vote for RR fun in a car that you can still buy new for 140 for the pro kit or around 210 for rtr with a brushless system, go look it up, big bore alloy shocks, 7075 alloy narrow chassis, decent spares available at great prices, seems strong. Only negatives im seeing is no way to adjust rear toe and the easy to swap out original 10mm front hexes, losi 22 are a straight swap giving 12mm as are lots of other front end 22 parts. Theres a section about it in the archives here.
